[Importance of an intact posterior capsule for the vitreous body. Complication of posterior capsulotomy].
The various extracapsular cataract surgery techniques keep the anatomy and physiology of the eye largely untouched, since both the intact posterior capsule and the crystalline lens form a diaphragm between the aqueous humour and the vitreous. If the posterior capsule opacifies--which occurs in up to 50% within five years postoperatively--a capsulotomy becomes necessary. This increases the rate of retinal detachment and cystoid macular edema. To date no pharmacologic or immunologic means exist to prevent posterior capsule opacification. Implanting the IOL into the capsule bag and the biconvex lens design by itself reduce the incidence of opacification. The biconvex optic of the IOL seals the gap in the capsule, if a capsulotomy has been performed; fluorophotometry shows us that the diaphragm function remains intact after in the bag implantation as compared to sulcus fixated IOL.
