This procedure is essentially the same as PRELEX except a fixed-focus lens is implanted rather than a multi-focal lens. Some patients are not suitable for PRELEX, but would benefit from removal of their natural crystalline lens and the insertion of a fixed-focus lens implant.

This group of patients includes those with specific refractive disorders, such as high myopia. Often these patients are outside the treatment range for LASIK and yet a multi-focal lens implant may not be appropriate. Significant astigmatism might also preclude patients from PRELEX surgery thus making Refractive Lens Exchange an option. For those interested in lens exchange but concerned about the risk of halos and night driving that can occur following PRELEX, once again Refractive Lens Exchange may be a more acceptable option.

Although rare, lens removal in high myopes does carry an increased risk of retinal detachment. As the surgical technique is similar to that for PRELEX, the common risks are as previously described in that section. We will discuss all risks with you in detail at your assessment to enable you to make a balanced decision.

There is now a new lens specifically designed to try and address the issue of halos in patients who do a lot of night driving. This lens effectively addresses the impaired contrast which occurs in low light following lens surgery. All options will be discussed with you at your assessment when you will have the chance to ask further questions. In the meantime we hope this information has been helpful.
