What Is Vitrectomy?
A vitrectomy is a microsurgical procedure performed by a vitreoretinal surgeon to treat various eye conditions. Modern vitrectomy techniques are also known as minimally invasive vitreous surgery (MIVS), with incisions measuring 0.5 mm or less. These incisions are usually self-sealing and sutureless, helping to reduce postoperative discomfort and recovery time.
When Is Vitrectomy Needed?
Vitrectomy may be used to treat various vitreous and retinal conditions. Whether surgery is appropriate depends on the specific condition, its severity and the findings of an eye examination.
How Is Vitrectomy Performed?
Tiny incisions are made in the sclera (the white of the eye). Microsurgical instruments are inserted through these incisions to remove vitreous gel, peel membranes, apply laser treatment or repair retinal problems, depending on the condition being treated.
What Fills the Eye After Vitrectomy?
The eye may be filled with a sterile salt solution, air, gas or medical-grade silicone oil at the end of surgery. Air and gas are gradually absorbed and replaced by fluid produced naturally by the eye. Silicone oil does not absorb naturally and may need to be removed in a separate procedure, depending on the patient’s condition and recovery.
Microsurgical instruments are inserted into the eye through very small incisions which usually require no stitching.

Frequently Asked Questions About Vitrectomy
Vitrectomy is a microsurgical procedure performed at the back of the eye. It may be performed as day surgery under local or general anaesthesia. Like any surgery, it carries some risks, but serious complications are uncommon.
After vitrectomy for certain conditions, such as macular disease and retinal detachment, the eye may be filled with gas or silicone oil. Adopting a specific head position can help support the treatment and recovery.
In some cases, maintaining a specific position during recovery can help support the treatment outcome.You may be asked to lie face down or position your cheek on a pillow. The recommended position and duration vary depending on your condition and type of surgery. Follow your surgeon’s instructions carefully.
If gas was used during vitrectomy, avoid air travel until the gas has completely disappeared, as cabin pressure changes can cause the gas bubble to expand and dangerously increase eye pressure.
Your eye surgeon will advise when it is safe to fly again.
Recovery typically takes a few weeks, but the time varies depending on the condition treated and the type of surgery. Vision may remain blurred while gas or other filling material is present, and visual recovery can continue for several months.
