Vitrectomy

What this procedure is

A vitrectomy is a type of eye surgery used to treat various vision problems. During this procedure, a surgeon removes some or all of the vitreous. This is the clear, gel-like substance that fills the middle of your eye and helps it stay round.

Once the gel is removed, your clinician may replace it with a clear fluid, a gas bubble, or silicone oil. These materials help hold the eye's tissues in place while they heal. Over time, your eye naturally replaces the gas or fluid with its own clear liquid.

This surgery is often done so the doctor can get a better view of the retina. The retina is the light-sensitive layer at the back of the eye that sends images to your brain. By removing the gel, the surgeon can repair damage to this area more easily.

What it treats or fixes

Your clinician might recommend a vitrectomy if you have a condition that affects the back of your eye. It is often used to clear away blood or scar tissue that blocks your vision. Common reasons for the procedure include:

• Retinal detachment: This happens when the retina pulls away from the back of the eye, which can lead to vision loss if not fixed.
• Diabetic retinopathy: People with diabetes may develop leaking blood vessels or scar tissue in the eye that needs to be removed.
• Macular hole: This is a small tear or opening in the center of the retina, which is responsible for sharp, detailed vision.
• Eye infections or injuries: A vitrectomy can help remove foreign objects or treat severe infections inside the eye.

The goal of the surgery is often to stabilize or improve your vision. While it may not always restore perfect sight, it can help prevent further vision loss from these serious conditions.

How common it is & where it's done

Vitrectomy is a common and well-established procedure. It is performed by an ophthalmologist who specializes in diseases of the retina. These specialists have advanced training in microsurgery to handle delicate eye tissues.

The surgery is typically done in a hospital or a specialized outpatient surgery center. In most cases, it is an outpatient procedure, which means you will likely go home the same day. Your care team will provide specific instructions on how to prepare and what to expect during your stay.

Because it is a specialized surgery, it is usually scheduled in advance. However, in certain cases, such as a sudden retinal detachment, it may be performed as an urgent procedure to protect your sight.

Recovery: What to Expect

After your vitrectomy, your eye may feel slightly sore or scratchy. Your clinician will likely place a patch over your eye to protect it for the first day. You will need to use special eye drops for several weeks to help the eye heal and prevent infection. Most people need to take a week or two off from work and avoid heavy lifting or intense exercise during this time.

If your clinician used a gas or oil bubble to help your retina (the light-sensitive layer at the back of the eye) heal, you may need to keep your head in a specific position, such as face-down, for a certain amount of time. It is very important to follow these instructions closely. You must also avoid air travel until your clinician confirms the bubble has dissolved.

Your vision will likely be blurry at first. This is normal as the eye heals and any gas bubble is gradually absorbed by your body. Your sight should slowly improve over the following weeks.

Risks & Possible Complications

While vitrectomy is a common procedure, it does carry some risks that your care team will monitor. These may include:

• Infection: This is rare but is treated with antibiotic drops.
• Bleeding: Some minor bleeding can occur inside the eye.
• High Eye Pressure: Your clinician will check your eye pressure during follow-up visits to ensure it stays in a healthy range.
• Cataracts: A cataract is a clouding of the eye's lens. Many people develop a cataract sooner than expected after having a vitrectomy.

You should contact your clinician if you experience a sudden decrease in vision, severe pain that does not improve with medicine, or a sudden increase in "floaters" or flashes of light.

Outcomes & Long-Term Results

The main goal of a vitrectomy is to stabilize or improve your vision. The final result often depends on the reason for your surgery, such as repairing a retinal detachment or treating complications from diabetes. For many patients, the procedure is successful in preventing further vision loss.

It can take several weeks or even months for your vision to reach its best level. Your clinician will schedule regular check-ups to track your progress. In some cases, you may need a new prescription for glasses or contacts once the eye has fully recovered and the vision has stabilized.

Emotional Support & Reassurance

It is natural to feel some anxiety about eye surgery. Please remember that vitrectomy is a standard procedure performed by specialists using very precise, modern technology. These techniques are designed to be as gentle as possible while protecting your sight.

Your medical team is there to support you. Do not hesitate to ask questions about your recovery or what you can do to help the healing process. Having a clear plan and a friend or family member to help you at home during the first few days can make the recovery process feel much more manageable.

Why doctors recommend it

A vitrectomy is a procedure where a surgeon removes the vitreous, which is the clear, gel-like fluid that fills the inside of your eye. Your clinician may recommend this if the fluid becomes cloudy, bloody, or is pulling on the retina (the light-sensitive layer at the back of the eye). This surgery allows the doctor to reach the back of the eye to fix specific problems that cannot be treated with eye drops or laser therapy alone.

Common reasons for this recommendation include:

• Diabetic retinopathy: When bleeding from leaky blood vessels clouds your vision.
• Retinal detachment: When the retina peels away from the back of the eye.
• Macular holes: Small tears in the center of the retina that affect detail vision.
• Eye infections or injuries: To remove debris or treat severe inflammation inside the eye.

Urgent vs planned treatment

The timing of your surgery often depends on the underlying cause. In some cases, a vitrectomy is an urgent procedure. For example, if you have a sudden retinal detachment or a serious eye infection, your clinician may want to perform surgery quickly to help protect your sight from further damage.

In other situations, the surgery may be planned in advance. If you have a macular hole or blood in the eye that is not clearing on its own, you and your doctor can discuss the best time for the procedure. This allows time to monitor the condition and see if other treatments, like laser therapy or injections, might help first.

Goals of treatment

The main goal of a vitrectomy is to improve or stabilize your vision. By removing the cloudy gel or scar tissue, the surgeon creates a clear path for light to reach your retina. If the retina is detached or torn, the surgery aims to move it back into its proper position so it can function correctly.

Success usually means preventing further vision loss or helping you regain some of the clarity you may have lost. While every person's eye heals differently, the procedure is designed to address the root cause of the problem and provide a better environment for the eye to recover. Your clinician will discuss what level of improvement is realistic for your specific condition.

Who may benefit

A vitrectomy is a type of eye surgery used to treat problems with the retina and the vitreous. The vitreous is the clear, gel-like substance that fills the middle of your eye. Your clinician may recommend this procedure if blood, scar tissue, or debris in the vitreous is blocking light from reaching your retina, which is the light-sensitive layer at the back of the eye that helps you see.

Common reasons for this surgery include:

• Diabetic retinopathy: This occurs when damaged blood vessels leak blood into the gel of the eye.
• Retinal detachment: This is a serious condition where the retina pulls away from the back of the eye.
• Macular holes: These are small tears or breaks in the center of the retina that can blur or distort your vision.
• Eye infections or injuries: Surgery may be needed to remove foreign objects or treat severe inflammation inside the eye.

When it may not be the right option

This surgery is often reserved for cases where vision loss is significant or the eye is at risk of permanent damage. If your symptoms are mild and do not interfere with your daily life, your care team might suggest monitoring the condition closely instead of performing immediate surgery.

Your clinician may also consider other treatments first. For example, some types of bleeding or retinal issues can be managed with laser treatments or special medicine injections. If the risks of surgery, such as the potential for developing cataracts (a clouding of the eye's lens), outweigh the likely benefits to your vision, it may not be the best choice for you at this time.

Questions to ask your care team

Deciding on eye surgery is an important step. You may want to bring a list of questions to your next appointment to help you feel more comfortable with the process and understand what to expect.

• What is the main goal of this surgery for my specific eye condition?
• Are there other treatments we should try before considering a vitrectomy?
• How much improvement in my vision can I realistically expect after the procedure?
• What are the most common risks or side effects I should be aware of?
• How long will the recovery take, and will I need to keep my head in a specific position after surgery?

In the procedure room

When you arrive in the procedure room, the care team will help you get positioned comfortably on a treatment table. To keep the area clean and prevent infection, a provider will gently wash the skin around your eye. A sterile drape, which is a protective cloth, will be placed around your head to keep the surgical area clean while leaving your eye accessible to the surgeon.

High-level steps

The surgeon begins by making tiny, precise openings in the sclera, which is the white outer wall of your eye. Through these small ports, they use specialized miniature instruments to complete the following:

• Removing the vitreous: The surgeon carefully suctions out the vitreous gel, the clear substance that fills the middle of the eye.
• Repairing the eye: Your clinician may remove scar tissue, use a laser to repair tears in the retina (the light-sensitive tissue at the back of the eye), or address other concerns.
• Replacing the fluid: Because the eye needs internal pressure to keep its round shape, the surgeon fills the space with a substitute. This is often a saline (saltwater) solution, a gas bubble, or silicone oil.

Anesthesia and pain control

To ensure you are comfortable, your clinician may use local anesthesia to numb the eye area completely. This means you will be awake but should not feel any pain. You may also receive a sedative through an IV to help you feel relaxed or sleepy during the procedure.

While you should not feel sharp pain, it is common to feel a sensation of pressure or see moving lights and colors while the surgeon works. If you feel any significant discomfort, the team can adjust your medication to keep you calm and comfortable.

Monitoring and safety steps

During the entire procedure, the surgical team monitors your heart rate, blood pressure, and oxygen levels to ensure you are safe. The surgeon uses a high-powered operating microscope that provides a detailed view of the inside of the eye, allowing for very precise movements.

In many modern vitrectomies, the incisions are so small that they are "self-sealing." This means they often do not require stitches and will close on their own as the eye heals. If stitches are needed, they are usually very thin and designed to dissolve over time.

Immediately after the procedure

Once the surgery is finished, you will be moved to a quiet recovery area. Your clinician will likely place antibiotic ointment on the eye and cover it with a patch and a hard plastic shield. This shield protects the eye from accidental rubbing or pressure while it begins to heal.

As the numbing medicine wears off, you might notice some mild soreness or a "gritty" feeling, as if there is a piece of sand in your eye. This is a normal part of the healing process. Your care team will monitor you for a short time before you are cleared to go home with a companion.

Typical procedure length

A vitrectomy typically takes anywhere from one to several hours to complete. The exact time depends on the complexity of the eye issue being treated and whether additional repairs, such as laser work, are needed. Your surgical team can provide a more specific time estimate based on your individual situation.

Common approaches (open vs minimally invasive)

Vitrectomy is a form of microsurgery. This means your surgeon uses a high-powered microscope and very small instruments to operate on the inside of the eye. Instead of large, open incisions, the doctor typically makes three tiny openings in the sclera (the white part of the eye).

Through these small openings, the surgeon inserts lights and tools to perform the work. Because the cuts are so small, this approach is generally considered minimally invasive. In many cases, the openings are self-sealing and may not require stitches, though your doctor will decide if stitches are necessary for your specific eye.

Partial vs total

During the procedure, the surgeon removes the vitreous gel from the middle of the eye. This is often necessary to clear blood or debris that blocks light, or to give the doctor access to the back of the eye to repair the retina. The amount of tissue removed depends on the specific condition being treated.

Once the vitreous is removed, it must be replaced to keep the eye’s shape. Your clinician may use one of the following substances to fill the space:

• Saline solution: Sterile salt water that is eventually replaced by your body’s natural fluids.
• Gas bubble: A bubble that holds the retina in place while it heals and slowly disappears on its own.
• Silicone oil: A clear oil used for more complex repairs that stays in the eye until a doctor removes it.

Revision or repeat procedures

While many people only need one surgery, there are times when a second procedure is planned or becomes necessary. For example, if your surgeon uses silicone oil to support the retina, a follow-up surgery is usually required months later to remove the oil once the eye has healed.

Additionally, vitrectomy can speed up the formation of cataracts (clouding of the eye’s lens). If you have not had cataract surgery before, your clinician may discuss the possibility of needing a procedure to treat cataracts in the future.

Tests and imaging that may be done

Before your surgery, your eye doctor needs to get a clear picture of your eye’s health and the condition of your retina. They will likely start by examining your eye with a special light and a magnifying instrument.

Your clinician may also order specific imaging tests to help plan the procedure:

• Ultrasound: This test uses sound waves to create an image of the inside of your eye. It is often used if the doctor cannot see the back of the eye clearly.
• Optical Coherence Tomography (OCT): This scan uses light waves to take detailed pictures of the retina, allowing the doctor to see its layers and check for swelling.

Medication adjustments

It is important to give your healthcare team a complete list of everything you take. This includes prescription medications, over-the-counter drugs (such as aspirin or ibuprofen), vitamins, and herbal supplements.

Some medicines, particularly blood thinners, can increase the risk of bleeding during surgery. Your doctor will review your list and tell you if you need to stop taking any of them temporarily.

Important: Only stop taking your medicines if your clinician specifically instructs you to do so. If you are unsure, ask for clear instructions on what to take the morning of your surgery.

Day-before and day-of instructions

To ensure your safety during the procedure, you will be given specific instructions on how to prepare. A common requirement is fasting. You will likely be told not to eat or drink anything (including water) after midnight the night before your surgery.

Because you will have anesthesia and your vision will be blurry, you cannot drive yourself home. You must arrange for a friend or family member to pick you up after the surgery is finished.

Here is a checklist for the day of your procedure:

• Follow all instructions regarding food and drink exactly as written.
• Wear comfortable, loose-fitting clothing.
• Arrive at the surgery center or hospital on time to complete any necessary paperwork.
• Ask your doctor if you should take essential morning medications with a small sip of water.

General surgical risks

Like any operation, vitrectomy carries some general risks, though serious problems are not common. Your surgical team takes many steps to keep you safe and comfortable throughout the process.

Standard risks associated with most surgeries include:

• Infection: Bacteria entering the surgical site.
• Bleeding: Excess bleeding during or after the procedure.
• Anesthesia reactions: Some people may have a reaction to the medicine used to numb the eye or put them to sleep.

Procedure-specific complications

Because vitrectomy involves working deep inside the eye, there are specific side effects that can occur. Your risks may depend on your age and your specific medical condition.

Possible complications include:

• Cataracts: This is the most common side effect, especially for adults over age 60. A cataract is a clouding of the eye’s natural lens. If you have not had cataract surgery yet, vitrectomy often speeds up the formation of a cataract.
• High eye pressure: Fluid pressure inside the eye may rise, particularly if gas or oil was used during the surgery.
• Retinal issues: In rare cases, the retina (the light-sensing layer at the back of the eye) may tear or detach.
• Lens damage: The natural lens of the eye can sometimes be touched or damaged during the procedure.
• Vision changes: You may need a new eyeglass prescription after your eye heals because the shape of the eye or its focus can change slightly.

How complications are treated

Most complications from vitrectomy can be successfully treated or managed. Your doctor will schedule follow-up appointments to monitor your healing and catch any issues early.

Common treatments include:

• Medication: Antibiotic eye drops are used to treat infections, and pressure-lowering drops can help manage high eye pressure.
• Cataract surgery: If a cataract develops or worsens after vitrectomy, it can be treated with a standard cataract surgery to replace the cloudy lens with a clear artificial one.
• Additional procedures: If the retina detaches or bleeds, further surgery may be needed to repair it.

Pain control medicines

Most people feel only mild discomfort after a vitrectomy. Your clinician may suggest over-the-counter pain relievers, such as acetaminophen or ibuprofen, to help with any soreness or a "gritty" feeling in the eye. In some cases, they might prescribe a slightly stronger medication for the first day or two if needed.

During the surgery itself, the eye is usually numbed with local anesthesia (medicine that blocks pain in a specific area) so you remain comfortable. It is important to tell your care team about any allergies to pain medications or if you have a history of stomach or kidney problems before starting any new medicine.

Antibiotics

To help prevent infection, your clinician will likely prescribe antibiotic eye drops. These are often started a day or two before the procedure and continued for a period of time afterward. These medicines work by killing bacteria that could potentially enter the eye during or after surgery.

In some instances, the surgeon may give a small dose of antibiotics directly into or around the eye at the end of the procedure. Your clinician will tailor this plan based on your specific needs. It is important to follow the exact schedule provided by your team to ensure the eye remains protected while it heals.

Blood thinners and clot prevention

If you take blood thinners (medicines that help prevent blood clots), your clinician will create a plan specifically for you. They will look at why you take the medicine and how it might affect bleeding during the vitrectomy. The goal is to balance the safety of your eye with the health of your heart and circulatory system.

You may be asked to continue your regular dose, or your surgical team might coordinate with your primary doctor to adjust the timing of your medication. You should never stop taking any prescribed blood thinners on your own, as this could increase the risk of serious health issues. Always share a full list of your current medications and supplements with your surgical team during your consultation.

Emergency warning signs

While serious complications are rare, immediate care is needed if you notice sudden, drastic changes to your eye. Seek help right away if you experience a sudden loss of vision or if your vision goes dark. This can sometimes be a sign of retinal detachment, which is when the back layer of the eye pulls away from its normal position.

You should also seek emergency care if you see a dark shadow or "curtain" moving across your field of vision, or if you feel severe eye pain that starts suddenly.

Call your surgeon or clinic if…

Your doctor will want to know about any symptoms that could signal an infection or high pressure in the eye. Contact your surgeon’s office if you notice:

• Redness or swelling that gets worse instead of better.
• Yellow or green discharge coming from the eye.
• Pain or deep aching that does not go away after taking your prescribed pain medicine.
• New flashes of light or a sudden increase in floaters (spots in your vision).

Expected vs concerning symptoms

Most people have: Mild soreness or a gritty, scratchy sensation in the eye. It is also normal for your vision to be blurry for several weeks after surgery. If your surgeon placed a gas or oil bubble in your eye to help it heal, your vision will be very poor until the bubble dissolves or is removed.

Call if: Your pain becomes sharp or severe, or if your vision gets significantly worse after initially improving. While some discomfort is part of the healing process, symptoms should generally improve day by day, not decline.

Non-surgical treatments

Before suggesting a vitrectomy, your clinician may recommend other treatments to manage your eye condition. For example, if you have diabetic retinopathy (damage to the blood vessels in the back of the eye), they might use laser therapy. This treatment helps seal leaking blood vessels or shrink abnormal ones.

Another common option involves medicine injected directly into the eye. These injections can help reduce swelling or stop the growth of new, fragile blood vessels. In many cases, these less invasive steps are the first line of defense to protect your sight.

Watchful waiting

In some situations, your clinician may suggest "watchful waiting." This means they will monitor your eye closely over several weeks or months without performing surgery right away. This is often an option if you have a small amount of blood in the vitreous (the clear, gel-like substance that fills the eye).

During this time, your body may naturally absorb the blood, and your vision might clear on its own. You will likely need frequent eye exams to ensure the condition is not getting worse. If the problem stays the same or improves, you may be able to avoid surgery entirely.

When surgery becomes the best option

Surgery usually becomes necessary when non-surgical treatments do not work or if the eye condition is more severe. For instance, if blood in the eye does not clear after a period of waiting, a vitrectomy may be the only way to restore clear vision.

Your clinician may also recommend surgery immediately for certain urgent issues, such as:

• Retinal detachment: When the retina (the light-sensing layer at the back of the eye) pulls away from its normal position.
• Severe eye trauma: Injuries that cause significant damage or bleeding inside the eye.
• Macular holes: Small tears in the central part of the retina responsible for sharp, detailed vision.

The main goal of moving to surgery is to prevent permanent vision loss and address problems that the body cannot fix on its own.

Hospital services that commonly perform this surgery

A vitrectomy is a specialized eye surgery. It is most often performed in an ophthalmology department, which is a hospital wing dedicated to eye health. You may also find this service at a dedicated eye surgery center or a vitreoretinal clinic. These facilities focus on the back of the eye, including the retina (the light-sensitive layer) and the vitreous, which is the clear, gel-like fluid that fills the center of the eye.

Because this procedure is often done as outpatient surgery, you may not need to stay in the hospital overnight. Your clinician may perform the surgery in an ambulatory surgery center, which is a facility designed for patients to have a procedure and go home the same day. These centers are equipped with specialized microscopes and tools specifically for delicate eye work.

Patient resources and support services

Recovery from eye surgery can take time, and many hospitals offer resources to help you through the process. Your care team may provide detailed guides on how to care for your eye at home. This often includes instructions on using eye drops to prevent infection and manage swelling. They may also provide information on what activities are safe to resume during your recovery.

Support services may include:

• Vision Rehabilitation: Specialists who help you adapt if your vision is temporarily or permanently changed.
• Patient Education: Materials or videos that explain what to expect during the healing process.
• Home Care Coordination: Assistance in setting up your home, especially if your clinician requires you to maintain a specific head position (like face-down) after surgery to help the eye heal correctly.

Questions for choosing where to have surgery

Choosing the right place for your surgery can help you feel more confident. You may want to look for a facility that has experience with your specific eye condition. Here is a short checklist of questions to ask your clinician or the surgical center:

• How many vitrectomy procedures does the surgeon perform each year?
• Is the facility equipped with the specialized microscopic tools and lasers needed for retina surgery?
• What kind of anesthesia (numbing medicine) is typically used for this procedure?
• Who should I contact if I have concerns or an emergency during the weekend or after hours?
• Does the center provide or recommend resources for specialized recovery equipment, such as face-down pillows, if they are required?

Conditions commonly treated by this procedure

A vitrectomy is a type of eye surgery used to treat various issues with the retina and the vitreous, which is the clear, gel-like substance that fills the middle of your eye. Your clinician may recommend this procedure if you have certain conditions that affect your vision or the structure of your eye.

• Diabetic retinopathy: This occurs when high blood sugar damages the tiny blood vessels in the retina, the light-sensitive layer at the back of the eye.
• Retinal detachment: This is a serious condition where the retina pulls away from its normal position.
• Vitreous hemorrhage: This happens when blood leaks into the vitreous gel, making it difficult for light to reach the retina.
• Macular hole: This is a small tear or opening in the macula, the part of the eye responsible for sharp, central vision.

Other reasons for this surgery may include severe eye infections, serious eye injuries, or complications that occur after cataract surgery.

Related symptoms people search for

Many people who require a vitrectomy first notice changes in their vision. While these symptoms can be caused by many different eye issues, your clinician can help determine if a vitrectomy is the right step for your specific situation.

Common symptoms that may be associated with these conditions include:

• Floaters: Seeing small spots, specks, or cobweb-like shapes that drift across your field of vision.
• Flashes: Noticing sudden bursts or streaks of light, similar to lightning bolts.
• Blurred vision: A general loss of sharpness or clarity in what you see.
• Shadows or "curtains": A dark area or shadow that seems to move across your side or central vision.

If you experience a sudden increase in floaters or a loss of vision, it is important to seek an evaluation from an eye care professional right away.

Evidence overview

Vitrectomy is a well-established surgical procedure used to treat serious conditions affecting the retina and the vitreous (the gel-like fluid in the middle of the eye). It is considered a standard treatment for issues such as retinal detachment, diabetic retinopathy, and macular holes. Medical professionals rely on this surgery to clear blood from the eye, remove scar tissue, or repair the retina.

Clinical evidence shows that vitrectomy is often effective at improving vision or preventing further vision loss. For example, success rates for repairing a detached retina are generally high, often reported around 90 percent. While the outcome depends on the severity of the condition and the health of the eye before surgery, it is a primary option for saving sight in many cases.

Safety notes and individualized care

Like any major surgery, vitrectomy has risks, though serious complications are relatively rare. Your surgical team will take specific precautions to protect your health. Potential risks include infection, bleeding, or increased pressure inside the eye. There is also a small chance that the retina could detach again, requiring further treatment.

One of the most common side effects is the development of a cataract (clouding of the eye’s natural lens). This often happens sooner than usual after a vitrectomy, particularly in older adults. Because of this, your clinician may discuss the possibility of needing cataract surgery in the future.

Your care plan will be tailored to your specific needs. This includes the choice of anesthesia, which may be local (numbing the eye while you stay awake) or general (where you are asleep). If a gas or oil bubble is placed in the eye to help the retina heal, you will receive specific instructions on how to position your head during recovery to ensure the best result.
