Refractive lens exchange.

Abstract

Advances in small incision surgery have enabled cataract surgery to evolve from being concerned primarily with the safe removal of the opaque crystalline lens to a procedure refined to yield the best possible postoperative refractive result. As the outcomes of cataract surgery have improved, the use of lens surgery as a refractive modality in patients without cataracts (clear lens extraction) has increased in popularity. The removal of the crystalline lens for refractive purposes, or so-called refractive lens exchange (RLE), offers distinct advantages over corneal refractive surgery in selected cases. Nevertheless, in some middle-aged patients with high refractive errors, corneal refractive surgery can be a safe and effective treatment. In addition, the use of multifocal lenses offers an alternative for the correction of presbyopia. A further advantage of RLE is that it simultaneously eliminates the need for cataract surgery in the future. The keys for success in RLE are effectiveness and consistency in the refractive outcome, providing at the same time surgical and postoperative safety. To achieve these goals, adequate indications following strict risk/benefit criteria and refractive precision based on accurate preoperative protocols for IOL calculation and selection are mandatory, together with an appropriate choice of surgical procedure based on the surgeon's skills, minimizing complications.
