Refractive lensectomy involves removing the natural lens in the eye, and replacing it with a plastic lens. This operation is essentially the same as it is done for older patients who develop a cataract, which is a clouding of the natural lens. In both situations, patients elect to have the lens implant to improve their vision and decrease their dependency on glasses. Refractive lensectomy is used especially for cases of high myopia, and high hyperopia. It is a relatively complex procedure, as it involves going into the eye, and has a different set of potential complications. Complications can include bleeding and infection inside the eye, retinal detachment, and other potential serious problems.
