Vitrectomy increases the formation of cataracts. Patients should consult with a physician about this risk before deciding whether or not vitrectomy is an appropriate treatment for them.

When vitrectomy is performed to reattach a retina, complications may include:

• Retinal tear
• Recurring retinal detachment
• Cataract
• Infection

Another potential complication associated with vitrectomy is fluid buildup in the clear tissue at the front of the eye (corneal edema).

All of these complications have the potential to temporarily or permanently impair vision. Clinical trials are investigating medication that may prevent or slow the progression of cataracts after vitrectomy.
