Eye surgeons have implanted fixed-focus IOLs for decades. Surgeons implanted the first multi-focal IOLs just about 20 years ago to treat patients with cataract. In the mid-1990s, doctors started inserting the multi-focal lens to treat presbyopia.
In 1998, American ophthalmologist Dr Kevin Waltz was the first eye surgeon in the world to undergo Lens Replacement surgery. He received multi-focal lenses to replace the natural lenses in his own eyes. As an eye doctor and a patient, Mr Waltz has lectured around the world describing his incredible visual improvement. He labelled the procedure PRELEX, which is short for PREsbyopic Lens Exchange. We now refer to this procedure as Lens Replacement or RLE for short.
The results in the UK and the USA led a progressive group of international ophthalmologists to include Lens Replacement as part of their options. Their presbyopic patients are now able to have clear vision, reduce or cut their dependence on glasses.
As a bonus, another great advantage of Lens Replacement is that you will never need treatment for cataracts.
