A cataract is a misting up of the natural lens, which sits just behind the pupil and helps to focus light on the retina. Cataract surgery involves removing the cloudy lens and replacing it with a clear synthetic implant called an intraocular lens (IOL). The focusing power of the IOL is chosen by your surgeon to reduce dependence on glasses after surgery.
About four out of five patients are completely free of glasses after Refractive Lens Exchange (RLE) with widely used contemporary multifocal Intra ocular lenses (IOLS).
• Monofocal IOLs – these lenses have on specific focal point. Most patients target good distance vision and wear reading glasses. This lens can also be set to give good reading vision with the patient wearing distance glasses post-surgery
• Multifocal IOLs – multifocal lenses aim to reduce spectacle dependence for a wider range of activities, including intermediate (computer screens) and near (reading) vision. If you are suitable for Refractive lens exchange, your surgeon will discuss which IOL type is the best option for you.
