Vitrectomy Surgery: How It's Done, Uses & Recovery
Vitrectomy removes the vitreous — the clear gel filling the back of the eye — giving the surgeon direct access to repair the retina. It's the foundation of modern retinal surgery, treating conditions that often can't be fixed any other way.
Quick Answer
Vitrectomy is a surgery that removes the vitreous — the clear, jelly-like gel filling the middle of your eye — to give the surgeon direct access to the retina at the back. It's used to treat serious conditions like retinal detachment, vitreous bleeding, macular holes, and epiretinal membranes, many of which can't be treated any other way. The removed vitreous is replaced with saline, a gas bubble, or silicone oil to help maintain the eye's shape and support healing. Recovery varies by condition, but vision typically stabilises over one to a few months.
Key Takeaways
- Vitrectomy removes the vitreous gel so a surgeon can directly repair the retina — sealing tears, peeling membranes, or clearing blood.
- It treats retinal detachment, vitreous hemorrhage, macular holes, epiretinal membranes, severe infection or injury, and retained lens fragments.
- Face-down posturing is only needed if a gas bubble was used — not every vitrectomy requires it.
- If a gas bubble is placed, flying or travelling to high altitude must wait until it's fully absorbed, usually several weeks.
- A cataract commonly develops in the months to years after vitrectomy if the natural lens is still present — this is expected, not a complication.
- Vision recovery is gradual, often taking several months to fully stabilise, and the final result depends heavily on how healthy the retina was before surgery.
What Is Vitrectomy Surgery?
The vitreous is a clear, jelly-like substance that fills the middle of your eye. It helps the eye hold its shape and lets light pass through to the retina, the light-sensitive layer at the back of the eye. When the vitreous becomes cloudy, filled with blood, infected, or starts pulling on the retina, vision can blur or even be lost suddenly.
Vitrectomy is a micro-surgery in which this vitreous gel is carefully removed from the eye. Once it's out, the surgeon has clear, direct access to the retina and other structures deep inside the eye — clearing anything cloudy, stopping bleeding, repairing retinal damage, and releasing traction on delicate retinal tissue. The removed vitreous is replaced with clear fluid, a gas bubble, or silicone oil, which helps the eye hold its shape while healing. Over time, the body's own fluid gradually replaces this.
What Conditions Does Vitrectomy Treat?
Retinal detachment — when the retina pulls away from the back of the eye, needing prompt surgical repair.
Vitreous hemorrhage — bleeding into the vitreous, often caused by diabetic eye disease.
Macular holes — a full-thickness break in the macula affecting central vision.
Epiretinal membranes — scar-like tissue that wrinkles and distorts the central retina.
Severe eye infection or injury — where the vitreous itself has become a source of ongoing damage.
Retained lens fragments — pieces of lens left behind after a complicated cataract surgery.
Many of these conditions simply cannot be treated by any other means — vitrectomy is often the only path to preserving or restoring vision.
What Symptoms May Suggest You Need a Vitrectomy?
Vitrectomy is not recommended lightly — it's typically advised when symptoms point to serious damage inside the eye:
These symptoms should never be ignored — when treated early, the chances of preserving or recovering sight are significantly better.
How Are You Evaluated Before Surgery?
Detailed eye exam: A thorough look at the retina and vitreous to understand exactly what's wrong.
OCT imaging: Cross-sectional scans of the retina that precisely map the extent of damage.
B-scan ultrasound: Used when bleeding or clouding blocks a direct view of the retina, to see what's happening behind it.
Blood tests & medical clearance: May be needed depending on your overall health and the complexity of surgery.
You'll also be advised to stop certain medications beforehand, and given clear instructions for the day of surgery to keep things safe and comfortable.
What Happens During the Procedure?
Anaesthesia
Local or general anaesthesia is given, depending on your case, so you feel no pain during surgery.
Tiny Incisions
Fine instruments are inserted through micro-incisions in the wall of the eye.
Vitreous Removal
The cloudy, bloody, or traction-causing vitreous gel is carefully removed.
Retinal Repair
With clear access, the surgeon repairs tears, peels membranes, or clears any remaining blood.
Eye Refilled
The eye is filled with saline, a gas bubble, or silicone oil, chosen based on what your retina needs to heal.
Will You Need to Posture (Face-Down) After Surgery?
Sometimes, but not always. If a gas bubble is used, you may be asked to hold a specific head position — often face-down — for several days. This lets the bubble press against the part of the retina that needs support while it heals. It's demanding, but it genuinely affects the outcome, which is why your surgeon will explain clearly how long and how strictly it's needed for your case.
Not every vitrectomy requires posturing — it depends entirely on whether a gas bubble was placed and where the repair was done. Your surgeon will tell you clearly beforehand whether this applies to you.
What Is the Recovery Timeline?
Recovery after vitrectomy depends on the condition treated and the material placed inside the eye. Immediately after surgery, the eye may feel sore, watery, or irritated, and an eye patch may be worn for protection. Vision is usually blurry at first — this is normal. Antibiotic and anti-inflammatory eye drops are prescribed and should be used exactly as recommended.
If a gas bubble was used, sight stays reduced until the bubble gradually absorbs over several weeks — you may notice a wobbling line across your vision as it shrinks, which is a normal part of the process. Most people return to light activity within one to two weeks, with vision continuing to improve over one to three months, and full stabilisation sometimes taking longer depending on how much damage existed before surgery.
Can You Fly or Travel to High Altitude After Surgery?
Not while a gas bubble remains in your eye. Changes in air pressure during flying, or even travelling to high altitude by road, can dangerously expand the gas bubble and raise pressure inside the eye. This restriction typically lasts several weeks, until your surgeon confirms the bubble has fully absorbed — always check before booking any travel after vitrectomy.
Will You Develop a Cataract After Vitrectomy?
If you still have your natural lens, a cataract commonly develops in the months to a couple of years after vitrectomy. This is expected — not a sign that anything went wrong — and it's straightforward to treat with routine cataract surgery once it becomes visually significant. In some cases, your surgeon may discuss combining both procedures.
What Are the Risks of Vitrectomy Surgery?
Soreness & Blurred Vision
CommonExpected in the days after surgery as the eye heals, settling with prescribed drops.
Cataract Progression
CommonExpected over the following months to years if the natural lens is still present.
Raised Eye Pressure
MildTemporary in most cases, managed with monitoring or drops.
Retinal Detachment
RareAn uncommon complication, treatable if caught and addressed promptly.
Infection or Bleeding
RareClosely monitored during recovery, as with any intraocular surgery.
Life After Vitrectomy Surgery
Most patients resume daily activities once the healing process is complete. Vision may not be perfect, but it is often significantly improved compared to before surgery. Long-term care involves regular eye exams, protecting your eyes from injury, and staying on top of underlying conditions like diabetes. Paying attention to any new symptoms and seeking care early goes a long way toward protecting your vision going forward.
How Much Does Vitrectomy Surgery Cost?
Vitrectomy cost depends on several factors: the underlying condition being treated, whether gas or silicone oil is used, whether cataract surgery is combined with the procedure, and the length of hospital stay required. Save Sight Centre can give you a clear, personalised estimate once your condition has been evaluated.

Frequently Asked Questions About Vitrectomy Surgery
Yes, vitrectomy is considered a major eye surgery as it is done inside the eye. However, it is also a procedure that is performed very regularly by eye surgeons. With modern surgical machines, improved resolution microscopes, and improved techniques, vitrectomy is very safe and quite effective.
No, vitrectomy surgery itself is not painful. The eye is anaesthetised using local anaesthesia, or the patient is given general anaesthesia, depending on the situation. During the surgery, you will not feel any pain. After the procedure, mild discomfort, soreness, or the feeling of a foreign object is common for several days. This is normal and usually settles down with the prescribed eye drops and pain relief medicine.
During this time, the eye heals and inflammation reduces. Vision may be blurry initially, which gradually improves. Full recovery could take a few months. The exact time depends on the condition treated and the complexity of the surgery.
Eyesight improves in most cases following vitrectomy, but this may not return fully to normal. The ultimate visual result essentially depends on how healthy the retina was before surgery, as well as how early the condition was treated.
Yes, vitrectomy may be performed in both eyes if necessary. However, it is not usually done on both eyes at the same time. Surgeons prefer to operate on one eye and let it heal before considering surgery on the other, if needed, so recovery stays safe and manageable.
Vitrectomy treats retinal detachment, vitreous hemorrhage (bleeding into the vitreous, often from diabetic eye disease), macular holes, epiretinal membranes that wrinkle the central retina, severe eye infection or injury, and retained lens fragments after complicated cataract surgery. Many of these conditions cannot be treated any other way.
Not always. Face-down positioning is only needed if a gas bubble was placed during your surgery, to keep it pressed against the part of the retina that needs support. Not every vitrectomy uses a gas bubble, so not every patient needs to posture — your surgeon will tell you clearly beforehand whether this applies to you.
Not while a gas bubble remains in your eye. Changes in air pressure during flying, or even travelling to high altitude, can dangerously expand the bubble and raise pressure inside the eye. This restriction typically lasts several weeks until the gas has fully absorbed — your surgeon will confirm exactly when it's safe.
If you still have your natural lens, a cataract commonly develops in the months to a couple of years after vitrectomy. This is expected, not a sign that anything went wrong, and it's straightforward to treat with routine cataract surgery once it becomes visually significant. Sometimes the two surgeries are combined.
