Refractive Lens Exchange (RLE) is a vision correction procedure used to treat presbyopia, hyperopia, and astigmatism.It is a type of refractive surgery that replaces the eye’s natural lens with an artificial intraocular lens (IOL) to correct refractive errors.
The procedure is done under local anesthesia and typically takes one hour.During the procedure, the natural lens is removed and replaced with an intraocular lens that is designed to correct your specific refractive error.
The IOLs used in RLE are usually monofocal, meaning they correct your vision for one distance, either near or far.This procedure can provide a long-term solution to most people, as the IOLs used are designed to last a lifetime.
RLE can be a safer alternative to LASIK or PRK, as no laser is used.Possible risks of the procedure include infection, inflammation, or glare and halos around lights.
