Refractive Lens Exchange (RLE)

RLE surgery involves removing the lens of the eye and replacing it with an intraocular lens implant. The procedure is essentially the same as a cataract operation with lens implant; however, in this case, the procedure is completed prior to cataract development. As such, individuals who undergo RLE will never suffer with reduced vision from cataracts.

RLE may be used to treat farsightedness, nearsightedness, astigmatism, and presbyopia. The optical results and quality of vision of RLE is superior to corneal procedures such as LASIK. With the benefit of sophisticated instrumentation to measure the length and curvature of the eye to within 1,000ths of a millimeter, and personalized software formulas, Dr. Singer is able to determine with a high degree of accuracy the proper lens implant power to decrease post-operative dependence on eyewear.

An accommodating intraocular lens can be implanted at the time of refractive lens exchange, which allows you to seamlessly see far, intermediate, and near. For the best results, both eyes should be implanted with the accommodating lens, as accommodation is a binocular event. However, the accommodating lens can be used in one eye only.

Dr. Singer's success rate with RLE procedures is over 99%. The risks of RLE include the rare event of retinal detachment (more of a risk with highly nearsighted eyes), and the risks of intraocular surgery (including the potential, albeit very uncommon, risk of infection).
