Abstract
Phakic refractive lens (PRL) for correcting myopia or hyperopia are disclosed. The lens is implanted in the posterior chamber of the eye, with no permanent point of fixation, such that it floats between the patient's iris and natural lens. The lens corrects refractive errors in the eye, while maintaining the fluid dynamics of the eye and not causing stress or damage to eye structures. The lenses are made from a flexible material (such as those having a hardness of from about 20 to about 50 Shore A), having a specific gravity of from about 0.9 to about 1.2 g/cm , and have a mass per unit area of from about 0.03 to about 0.30 mg/mm . The method for using those lenses and surgical kits including those lenses are also disclosed.
