Abstract

Pars plana vitrectomy is usually performed to remove vitreous opacities, reduce vitreoretinal traction, restore the normal anatomical relationship between the retina and retinal pigment epithelium (RPE), and reach the subretinal space. This surgical method involves an approach in which 3 ports (sometimes 4) are placed 3-4 mm posterior to the surgical limbus, depending on the condition of the crystalline lens. Complications related to conjunctiva, sclera, cornea and lens can be seen after or after vitrectomy surgery. Nuclear sclerotic cataract is the most common complication of vitrectomy. Cataracts may develop in up to 90% of phakic eyes in patients older than 50 years of age within 3-6 months after vitrectomy. There may also be refraction changes, iris defects, and an increased risk of long-term open-angle glaucoma.
