Intraocular Lenses (IOLs): A Visionary Leap in Modern Ophthalmology
Intraocular lenses(IOLs) represent a revolutionary development in the field of ophthalmology, offering renewed vision and quality of life to millions worldwide. These artificial lenses are implanted inside the eye to replace the natural lens that is removed during cataract surgery or to correct refractive errors such as myopia, hyperopia, or astigmatism. With advancing technology and an aging global population, IOLs have evolved from being basic monofocal devices to sophisticated multifocal, toric, and accommodating lenses that offer a tailored visual experience.
Understanding Intraocular Lenses
An intraocular lens is a small, transparent, artificial lens made from materials such as silicone, acrylic, or other biocompatible substances. It is designed to focus light onto the retina, mimicking the function of the eye's natural crystalline lens. IOLs are most commonly used in cataract surgeries, which are among the most frequently performed surgeries globally.
Following the removal of the cloudy natural lens (cataract), the IOL is implanted into the same location—usually the capsular bag within the eye. The procedure is quick, safe, and highly effective in restoring vision.
