Follow-up of 3 patients with Ridley intraocular lens implantation

Three patients in whom Ridley intraocular lenses (IOLs) were successfully implanted more than 42 years ago are presented. One case had traumatic cataract at age 13. The other 2 had surgery for unilateral cataract of unknown etiology at about age 40 and surgery on the second eye approximately 40 years later. A review of other reports of late-term results with this IOL is included.
