The first surgery in a human eye was performed in 1949, and approximately 1000 lenses have been implanted worldwide.1 ,2 Since then, significant changes in IOL technology have allowed ophthalmic surgeons to correct not only aphakia, but also other refractive errors such as astigmatism or presbyopia. To date, only a few cases with a Ridley IOL and a long postoperative follow-up of 30–40 years have been reported.3 Sixty-four years after the first IOL implantation, we have had the opportunity to analyse a Ridley IOL implanted 45 years ago, following its explantation. To our knowledge, this is one of the longest reported explantations of this type of IOL.

A 30-year-old man underwent surgery for a traumatic cataract in the right eye and a Ridley IOL was implanted. Forty-five years later, the patient suffered a car accident that caused an …
