It is a surgery to correct refractive errors. It differs from the other methods of refractive laser surgery for myopia, hyperopia and astigmatism as it does not remodel the cornea, but replaces the natural lens of the eye.
The Natural Lens Replacement (NLR) has some common features with cataract surgery. The ophthalmologist removes the natural lens using ultrasound and replaces it with an intraocular lens (IOL). Correction may involve either close or distant vision, depending on the patient's refractive problem.
The Natural Lens Replacement (NLR) method is mainly recommended for those who already suffer from presbyopia and can not undergo refractive laser surgery for myopia, hyperopia and astigmatism to remodel the surface of the cornea.
