The current modality for correcting unilateral aphakia is by the use of daily wear hard and soft contact lenses and by the use of intraocular lens implants. The use of the Cooper Permalens soft contact lens as an extended wear lens for correction of aphakia was investigated in 177 eyes. The relative merits of the extended wear lens are discussed with emphasis on fit, visual function, and contact lens-related problems.
