Steps in intracapsular cataract operation. A, Cryoprobe is activated by N2 or CO2 source. B, Conjunctival tissue is recessed to expose limbus. C, Incision is made into anterior chamber for distance of about five clock hours. D, Peripheral iridectomy is done to prevent pupillary block by vitreous gel. E, Cataract is removed with cryoextractor. F, Iris is reposited into eye, and anterior chamber is re-formed. G, Wound is sutured with fine 10–0 nylon sutures.

Steps in extracapsular cataract operation. A, Conjunctival tissue is recessed to expose limbus. B, Small incision is made into anterior chamber. C, Anterior capsule is incised with a sharp bent needle. D, Incision is enlarged to five clock hours. E, Nucleus is expressed by pressure at scleral wound transmitted to vitreous gel. F, Residual cortex after anterior capsule and nucleus have been removed. G, Residual cortex is removed with irrigation and aspiration by automated or manual technique. H, Wound is sutured with fine 10-0 nylon sutures.

Steps in phacoemulsification. A, Kelman phacoemulsification instrument. B, After conjunctival tissue is recessed, a 2-mm incision is made into anterior chamber. C, Anterior capsule is incised with a sharp bent needle. D, Nucleus is fragmented and aspirated. E, Residual cortex is removed by automated irrigation and aspiration. F, Incision is closed with a few sutures.

A, Specular microscopic photograph showing healthy corneal endothelium before cataract removal and placement of intraocular lens. B, Same patient 2 months after a difficult surgical procedure, showing loss of endothelial cells and enlargement of remaining cells to cover areas of loss. Corneal edema is beginning to be evident clinically.
