Share 23/04/2019 What are Lens options for Cataract? Intra-Ocular lenses (IOLs) are medical devices implanted inside the eye replacing the eye's natural lens that is removed during the cataract surgery. The most important aspect of a Cataract evaluation is the selection of the most suitable IOL. There are many different IOLs, most requiring a slightly different implantation technique and recommended for different pre-existing vision problems as listed below: • Monofocal lens: These lenses are the most commonly implanted lenses today. They provide high-quality vision at a single focal point (usually at distance). • Toric lens: Toric IOLs are premium intraocular lenses that correct astigmatism. They have different powers in different meridians of the lens that help correct astigmatism and to give clearer vision and reduce dependence on glasses • Multifocal lens:Multifocal intraocular lenses have a variety of regions with different power within the lens that allows individuals to see at a variety of distances, including far, intermediate, and near. Not everyone is a candidate for multi focal lens and our team of expert doctors will carry out a detailed preoperative examination to recommend the right one. • Tri focal: Trifocal lenses are the most advanced intraocular lenses (IOLs) available today, providing clear vision for close, intermediate and far distances, without gaps in between. They are designed to enable a high degree of independence from glasses for patients leading an active life and wishing to do without visual aids. • Toric Tri focal: Toric trifocal lenses are recommended for patients with astigmatism undergoing cataract surgery. This treatment option enables patients to get back to driving, reading books and using electronic devices without contacts or eyeglasses with tolerable side effects. • EDOF: Extended Depth of Focus (EDOF) is a new type of IOL used in cataract surgery for patients with Presbyopia. EDOF lenses work by creating a single elongated focal point to enhance “range of vision”including far, intermediate and near vision thus providing clear vision at different distances. If you are undergoing cataract surgery, do discuss with your surgeon, the pros and cons of each of the IOLs and choose the one most suited to you.
