IOL Refrattive

IOL Refrattive


Cataract surgery involves replacing the cloudy natural lens in your eye with a clear, intraocular lens or IOL. These IOLs allow you to see clearly at near or distance but not both. This is because conventional IOLs only have a single focus. New multifocal refractive IOLs have unique focussing zones in the lens. These zones optimise focus for distance, intermediate and near vision. The procedure to insert the multifocal IOL is the same as conventional cataract surgery where the artificial lens replaces the natural cloudy crystalline lens. Under normal lighting conditions, central focussing zones allow a continuous focus over most distances. The majority of people alternate from near to far and most distances in between. During low light conditions, the outermost zone further optimises vision for distance vision. The optical design of modern multifocal IOLs also help reduce haloes that are often problematic prior to cataract surgery. Reinstate your vision by enjoying improved clarity for multiple distances with multifocal IOLs.
