IOL stands for Intraocular Lens. It is a type of artificial lens that is implanted in the eye, typically during cataract surgery. When the natural lens of the eye becomes cloudy due to cataracts, it is often removed, and an IOL is inserted to help restore clear vision.
Intraocular lenses can be made from various materials, and they come in different shapes and designs to accommodate the specific needs of the patient. Some IOLs are designed to correct vision for distance, while others may help with near vision as well. There are also multifocal IOLs that can provide a range of vision, allowing for better focus at varying distances.
The use of IOLs has greatly improved the outcomes of cataract surgery, allowing many patients to enjoy improved vision without the need for glasses or contact lenses after the procedure.
