Intraocular lens prostheses in cataract surgery.

The introduction of intraocular lens prostheses presents some real advantages for aphakic patients, but these must be balanced against practical and theoretical objections. Indications include the patient's advancing age, inability to use contact lenses and the presence of monocular cataract. Contraindications include the young patient, the one-eyed patient, and the presence of any ocular disease known to prejudice success.
