Vitrectomy is a surgery to remove some or all of the vitreous humor from the eye. Anterior vitrectomy entails removing small portions of the vitreous from the front structures of the eye—often because these are tangled in an intraocular lens or other structures. Pars plana vitrectomy is a general term for a group of operations accomplished in the deeper part of the eye, all of which involve removing some or all of the vitreous—the eye’s clear internal jelly
Endolaser (Endophotocoagulation): It is a procedure wherein laser is done by a probe put in the eye during vitreous surgery. It is used to treat retinal tears in retinal detachment and to do panretinal photocoagulation in proliferative retinopathies.
