Surgery on the back of the eye to treat retinal and vitreous problems: what it involves, the demanding recovery, and how to choose a retinal surgeon.

What vitrectomy is for
Vitrectomy is surgery on the back of the eye, where the surgeon removes the vitreous, the clear gel that fills the eye, to gain access to the retina. It treats serious conditions that threaten sight, and is a major step up in complexity from front-of-the-eye procedures such as cataract or laser surgery.
It is used for retinal detachment, macular holes, a wrinkled membrane on the macula, severe bleeding inside the eye from diabetes, and complications of advanced eye disease. This is sight-saving or sight-restoring surgery driven by medical need. Because it is delicate retinal surgery with a demanding recovery, the experience of the surgeon and the arrangements for close follow-up matter far more than any consideration of price.
What the operation involves
Through several tiny openings in the white of the eye, the surgeon removes the vitreous gel and then carries out the repair the eye needs: reattaching a detached retina, closing a macular hole, peeling away a scar membrane, or clearing blood. The instruments used are extremely fine, and modern small-gauge systems often allow the openings to seal without stitches.
Depending on the condition, the eye may be filled at the end with a gas bubble or, in complex cases, silicone oil to hold the retina in place while it heals. A gas bubble is absorbed naturally over weeks, whereas silicone oil is usually removed in a later operation. The use of a gas or oil tamponade is what drives some of the most demanding parts of recovery, including the need to hold a specific head position afterwards.
What vitrectomy costs and what is included
Vitrectomy is a complex operation, and its cost reflects the specialised retinal surgery, the equipment and any tamponade used. Prices vary considerably with the condition being treated and whether additional steps, such as combined cataract surgery, are involved. Because it is medically necessary, treatment at home may be partly covered, so weigh any saving carefully against the practicalities of recovery.
A proper package should cover the assessment, the operation and any gas or oil used, medications, and the follow-up that retinal surgery requires. If silicone oil is used, ask whether the later operation to remove it is included. The most important consideration is not the headline price but the surgeon's retinal experience and the plan for close post-operative monitoring.
Choosing a retinal surgeon and clinic
Vitrectomy is performed by vitreoretinal surgeons, a specialised subgroup of ophthalmologists. Choose a board-certified surgeon who subspecialises in retinal surgery at an accredited hospital with JCI, TEMOS or ISO recognition, and ask how often they perform vitrectomy for your specific condition.
Because recovery is involved and complications need prompt attention, continuity of care is essential. Confirm how you will be monitored in the early weeks, especially if a gas bubble or silicone oil is used, and arrange a retinal specialist at home to continue your care. If treatment is abroad, plan a sufficient stay and a clear handover, including whether and when any oil-removal operation will be done.
Recovery and posturing
Vitrectomy recovery is more demanding than most eye surgery, and it depends heavily on the condition treated and whether a tamponade is used. Vision is often blurry for weeks, and improvement can be gradual over months. The eye is sore at first, and you will use anti-inflammatory and antibiotic drops during healing.
If a gas bubble or oil is placed, your surgeon may require you to maintain a specific head position, sometimes face-down, for a period of days to help the retina heal correctly, which can be physically demanding. Crucially, you must not fly while a gas bubble is in the eye, because changes in air pressure can dangerously raise eye pressure; this directly affects when you can travel home and must be planned for in advance.
Risks and what if something goes wrong
Vitrectomy is effective but carries the risks of major intraocular surgery. The most common consequence is that cataract development speeds up, so many patients eventually need cataract surgery afterwards. Other risks include raised eye pressure, infection, bleeding, and in some cases a new or recurrent retinal detachment that may need further surgery.
The success of the operation often depends on following post-operative instructions, particularly posturing and the absolute ban on flying with a gas bubble, so understanding these in advance is part of staying safe. Because retinal complications can develop and need prompt treatment, confirm before you travel who manages them and ensure your home retinal specialist has your full records and your follow-up plan, including any planned oil removal.
Frequently asked
What conditions does vitrectomy treat?
It treats serious back-of-the-eye problems such as retinal detachment, macular holes, wrinkled macular membranes, severe bleeding inside the eye, and complications of advanced diabetic eye disease.
Why might I have to lie face-down afterwards?
If a gas bubble or oil is placed to hold the retina in position, a specific head posture, sometimes face-down, keeps the bubble against the area that needs to heal. This can last several days.
Can I fly after a vitrectomy?
Not while a gas bubble remains in the eye, because changes in cabin pressure can dangerously raise eye pressure. You must wait until the gas has absorbed, which can take weeks, so plan travel carefully.
How long does vision take to recover?
Vision is usually blurry for weeks and improves gradually, sometimes over several months. The final result depends on the underlying condition and how much damage occurred before surgery.
Will I need cataract surgery later?
Often yes. Vitrectomy tends to speed up cataract formation, so many patients eventually need cataract surgery, sometimes within a year or two of the vitrectomy.
Is vitrectomy safe to have abroad?
It can be at an accredited centre with an experienced retinal surgeon, but the demanding recovery and flying restrictions mean you must plan a long enough stay and arrange close follow-up with a retinal specialist at home.
