Intraocular lenses (IOLs) are artificial lenses implanted into the eye to replace the natural lens during cataract surgery or refractive lens exchange. These lenses play a crucial role in restoring clear vision, offering patients improved quality of life. With advancements in technology, various types of IOLs, such as monofocal, multifocal, and toric lenses, have emerged, catering to the diverse needs of patients. In this article, we will explore the leading manufacturers of intraocular lenses and their contributions to the field of ophthalmology.
