A vitrectomy is used to remove the vitreous humor or gel-like substance in the eye. This approach is often used to treat vision problems that are caused when foreign matter invades the retina or vitreous.
When light rays pass through the eye, any foreign matter in this area will cast shadows on the retina, which results in visual distortions and reduced vision quality.
The most common causes that necessitate a vitrectomy include:
When anesthesia takes effect, your surgeon will make small incisions in the eye; behind the iris but in front of the retina.
A light pipe (microscopic flashlight), infusion port (which is used to replace fluid in the eye) and vitrector (cutting device) are used together to preform the vitrectomy. Once the vitreous humor has been removed from the eye, a saline liquid is used in its stead.
The procedure is often preformed specifically by a vitreoretinal specialist. Patients will likely need to use antibiotic and antiinflammatory eyedrops after surgery, as prescribed by your ophthalmologist.
