Latest developments in intraocular lenses.

[ILLUSTRATION OMITTED]

The first intraocular lens (IOL) for cataract surgery was implanted by Sir Harold Ridley in 1950 at St Thomas' Hospital in London. As most of the early cases had a disastrous outcome, IOL implantation fell into disrepute and it was not until some 30 years later that advances in IOL design, surgical technique, viscoelastics and surgical instrumentation began to make IOL implantation a safer procedure. IOL implantation is now the accepted routine for cataract surgery and there have been major advances in IOL technology in recent years. The goal of cataract surgery in the 21st century has moved from restoring sight to correcting refractive error and improving the quality of the patient's vision postoperatively. This article outlines some of the currently available IOLs that forward this aim.
