Leading London ophthalmologist Mr Danny Mitry speaks to Top Doctors about what to expect and the risks of vitrectomy surgery in this informative article.
What is vitrectomy surgery?
Vitrectomy surgery is done as a day case, small gauge procedure, often with the patient awake.
What happens after the operation?
After the operation, the eye is usually red and sore, and the vision tends to be blurred for the first, at least, few days after the procedure.
The eye will feel as though there's a foreign body in the eye and there'll be a certain amount of light sensitivity.
How does the gas bubble used in the procedure affect my eye?
In vitrectomy surgery, we often use a gas bubble inside the eye. If there's a gas bubble inside the eye, the vision will be blurred for the duration that gas stays in your eye. This can be up to four, or sometimes six weeks.
The gas bubble will gradually disappear from the vision and your vision will recover.
Are there things I should avoid doing after undergoing vitrectomy surgery?
With the gas in your eye, you can't take air travel due to changes in pressure which are unsafe for the eye. Sometimes after vitreoretinal surgery, we'll ask you to posture or position yourself in a particular way for the first 48 to 72 hours after the operation depending on the reason for the surgery.
Do you get cataracts after vitrectomy?
Cataract, if you don't already have one, does tend to accelerate after vitrectomy surgery and many people who will go on to need cataract surgery in the first two years following a routine vitrectomy.
What are the risks of vitrectomy surgery?
During vitrectomy surgery, we enter into the back part of your eye behind your lens to remove the vitreous (the gel inside your eye) and undertake any treatment that's required to the retina itself. The risks of surgery are less and less nowadays, with modern techniques.
The chances of significant sight loss are commonly from:
- an infection or;
- a serious bleed behind the eye.
They both occur in less than in one in a thousand cases.
The chances of needing a second operation are approximately one per cent from a retinal detachment, or another unexpected occurrence.
The biggest risk that many people are aware of, is the development of cataract, which occurs in approximately 90 per cent of people following vitrectomy surgery. Oftentimes, the development of this cataract requires further operation to remove the cataract, at least one or two years following the original operation.
