Hard contact lens corrections in aphakia.

Hard contact lens correction of aphakia is best performed with a single cut lens by a trial lens fitting. Lenticular design may be necessary. Continuous wear over age 70 may be necessary to achieve success and acceptance in more than 30% of aphakic wearers. Soft lenses are usually not practical in the author's experience. The increased use of intraocular lenses is decreasing the need for aphakic contact lenses. Merits of the hard contact lens in aphakia are discussed as a practical approach to the correction of vision by the ophthalmologist, and indications for single cut lenses and lenticular design are outlined.
