Intraocular Lenses (IOLs) are specialized implants used during cataract surgery to replace the natural lens of the eye that has become cloudy. These lenses help restore clear vision by focusing light properly onto the retina. IOLs come in various types, including monofocal, multifocal, and toric lenses, each designed to meet the specific needs of patients. Monofocal lenses provide clear vision at one distance, while multifocal lenses offer a range of vision, and toric lenses correct astigmatism. IOLs are essential for cataract surgery, providing patients with improved vision and enhanced quality of life after the procedure.
