Diffractive multifocal intraocular lens implants for unilateral cataracts in prepresbyopic patients.

Multifocal intraocular lenses allow pseudophakic patients to obtain good near and distance visual acuities without an additional near correction. We report our experiences in implanting diffractive multifocal intraocular lenses in prepresbyopic patients with acquired unilateral cataracts and assess their postoperative visual acuities and stereoscopic vision. Accommodative function in patients following cataract surgery is discussed.

Proplast implant in Tenon's capsule after excision of the eye.

Hitherto implants used after enucleation have generally been extruded because of infection or tissue rejection. Proplast, an inert alloplastic material prepared from a combination of Teflon fluorocarbon polymer and vitreous carbon fibres, is a grey felt-like material which, when wholly implanted, is invaded by fibrous tissue and not rejected. Hemispherical implants of Proplast have been used in sixteen cases, no rejection has occurred to date (18 months), and movement of the implant has been good. At operation, the obliques are sutured posterior to the implant so as to hold it forwards and increase movement. The rectus muscles are sutured anterior to the implant in cruciate fashion. Tenon's capsule and the conjunctiva are closed separately.
