Intraocular lenses (IOLs) are artificial lenses implanted in the eye to replace the natural lens removed during cataract surgery. There are several types of IOLs, each with its own benefits and limitations.
One type of IOL is a monofocal lens, which is designed to provide clear vision at a single distance. Patients who choose a monofocal lens will usually need to wear glasses or contact lenses to correct their vision at other distances.
