What Is a Vitrectomy?
Vitrectomy is micro-incision surgery inside the eye. The vitreous gel — which can contract, bleed or hold the retina down — is carefully removed and replaced with a clear saline-like fluid, gas or oil. Working through tiny ports, the surgeon can then address the underlying problem directly: peeling membranes off the macula, removing scar tissue pulling on the retina, closing retinal tears and flattening a detached retina against the eye wall.
Common reasons vitrectomy is considered include retinal detachment (especially complex or tractional types), vitreous haemorrhage that does not clear, macular hole and epiretinal membrane, dropped lens material, and some cases of severe eye infection or trauma. Whether surgery is appropriate — and which technique fits — is decided from examination and imaging, always with alternatives discussed.
Before, During and After Surgery
Before: a pre-operative assessment checks fitness, reviews medications (including blood thinners, managed with your physician — never stopped on your own), and explains anaesthesia, which may be local with sedation or general, depending on the case and patient factors. Consent covers goals, limitations and risks honestly.
During: the operation is typically performed as day-care through sutureless micro-incisions. Duration varies with complexity. A gas bubble or silicone oil may support the retina afterwards.
After: individualised instructions govern head positioning where a bubble is used, activity limits, eye drops, and review timing. Air travel and altitude changes are prohibited while gas remains — the duration is specific to your gas and your surgeon's advice, never a universal number. Vision recovery is gradual: days to weeks with gas, longer in some macular conditions. Follow-up is structured and unhurried, with warning signs (pain, redness, sudden drop, increasing floaters or shadow) clearly documented for same-day review.
Results and Honest Expectations
Vitrectomy achieves its anatomical goals in the large majority of cases, but anatomy and comfort are not the same as vision: recovery depends on what the condition did to the retina before surgery, especially the macula and its duration. Cataract commonly accelerates after vitrectomy in phakic eyes and may need surgery later; pressure rise, infection and redetachment are among the discussed risks. Every prognosis at this practice is individual and evidence-based — no percentages are quoted to you that cannot be justified for your specific eye.
Common questions
Is vitrectomy major surgery?
It is delicate micro-surgery, usually day-care with tiny self-sealing incisions — significant, but far less invasive than the name suggests.
Will I be awake?
Often yes, with anaesthesia around the eye plus sedation for comfort; general anaesthesia is used in selected cases, especially for children or longer operations.
Does the gas bubble affect vision?
Yes — while present, vision through a gas-filled eye is very poor, and it clears from top to bottom as the gas absorbs over weeks. Your surgeon states your expected timeline.
Can I fly after vitrectomy?
Not until your surgeon confirms the gas has fully absorbed and permits it. Flying with intraocular gas can be blinding — this rule is absolute.
How long is recovery?
Surface healing is days; functional recovery is typically weeks, and macular conditions can take months. Follow-up schedules reflect this.
Will I need to lie face-down?
Positioning requirements are individual — some patients do, some don't, and duration varies. Follow your personal written instructions only.
What are the risks?
Infection, bleeding, pressure rise, cataract, redetachment and, rarely, further surgery. Each is explained in context of your eye before consent.
Can a macular hole close without surgery?
Some small, recent holes can self-close, but most symptomatic holes are surgical discussions. Observation versus surgery is a structured conversation.
Do I stop blood thinners before surgery?
Never on your own. The team coordinates any adjustment with your prescribing physician based on your surgical and medical risk.
What if my vision doesn't improve after surgery?
Outcomes depend on pre-existing retinal damage. Honest pre-operative counselling sets realistic expectations, and rehabilitation options are reviewed if recovery plateaus.
