In this video Dr Suresh K Pandey, Director, Suvi Eye Institute & Lasik Laser Center, Kota, India (www.suvieye.com; E-mail:[email protected]) discuss about common eye disease Cataract and its management during an interview done by a T V reporter . Speaking in Hindi language, Dr Suresh Pandey explains about three major age-related eye diseases (AREDs) — cataracts, glaucoma, and diabetic retinopathy that affect people after the age of 50 years. Intraocular lenses (IOLs) are artificial lenses used to replace the eye's natural lens that is removed during cataract surgery. At Suvi Eye Institute & Lasik Laser Center, Kota, Dr Suresh Pandey & Dr Vidushi Pandey use all of the different IOLs and techniques described in this information write up.Accommodating and Multifocal IOLs- Premium Lenses: In 2003, the Accommodating IOL was FDA approved for use in the United States and in 2005, new generation Multifocal Lenses became FDA approved. These IOLs improve both distance and near vision without glasses and do not require the reduction in depth perception associated with monovision. However, they have their pros and cons also. Accommodating IOL -- Crystalens The Crystalens, manufactured by Bausch and Lomb, gained FDA approval in the fall of 2003. The First Crystalens implantation at SuVi Eye Institute, Kota was performed in June 2010 and so far the results are excellent. It was designed to restore some of the eye's natural accommodation ability. In all of us, with the passage of time, the eye's ability to accommodate is reduced. Presbyopia results and many people start needing reading glasses when they reach the age of 40 to 50. Accommodation refers to the ability of the eye to change focus from near to far and back again with all distances in between.The ciliary muscle contracts to enable this accommodative mechanism to occur. When the intraocular lens is removed, the ciliary muscle still retains its ability to contract and relax and the Crystalens utilizes this normal physiologic mechanism. The Crystalens has hinges on the sides of the implant permitting it to move with contraction and relaxation of the ciliary muscle. As a result, focusing is enabled from far to intermediate to near range. The Crystalens is the only accommodating IOL that has been approved in the United States, however, many other lenses are in the research and development stage. The Crystalens often provides good distance and intermediate vision. Near vision has been improved with the latest Crystalens models, but patients commonly require a blended/ monovision approach to reduce the need for reading glasses. Multifocal lenses - ReSTOR and Tecnis: The ReSTOR Multifocal IOLs are manufactured by Alcon, USA and work by combining the strengths of apodized diffractive and refractive technologies to provide focus at multiple ranges. The lens has concentric circular ridges that are exceedingly small and permit the eye to change its range of focus. The Tecnis Multifocal Diffractive IOL is manufactured by Abbott Medical Optics. This IOL has multiple zones to provide near, intermediate and distance vision. Both types of multifocal lenses provide good distance and near vision, and come withaspheric optics. Vision for each IOL varies based on lighting circumstances. At SuVi Eye Institute, Dr Suresh Pandey & Dr Vidushi Pandey utilizesblended/ monovision and accommodating and multifocal IOLs. Effort is made to choose the approach and IOL that is best suited for a given patient. Each approach and IOL has its own pros and cons and not all patients are candidates for new technology lens implantation. It is important to appreciate that none of the approaches or lOLs provide total freedom from the use of glasses for distance or near vision and all patients must understand that they may need glasses after cataract surgery. However, blended /monovision and accommodating / multifocal IOLs provide an excellent opportunity for patients to have reduced dependence on glasses. Specific visual needs and sensitivity to glare and halos help direct which IOL is best for a given patient. Astigmatic Keratotomies and Toric IOLs for treatment of Astigmatism Astigmatism occurs when the front surface of your eye (cornea) has a different surface curvature in one direction compared to the other. Dr Vidushi & Dr Suresh Pandey will often help reduce the astigmatism of the eye to improve the quality of vision after cataract surgery. One successful way to reduce astigmatism is to make small incisions in the cornea called astigmatic keratotomies. Another method employs implantation of a "Toric" IOL.
