CATARACT & IOL SERVICES
CATARACT & IOL SERVICES
The human crystalline lens, which is clear and transparent, is part of the focusing mechanism of the eye. With the age, the lens becomes cloudy and opaque, thereby hampering normal vision. Any opacity in the crystalline lens which leads to decreased vision, is called “CATARACT or “SAFED MOTIA” Cataract should be removed as soon as it begins to affect daily activities. With any of the mentioned symptoms setting in, it is the right time to go for cataract removal. DO NOT WAIT FOR THE CATARACT TO GET MATURE as unnecessary delay can lead to unavoidable complications and will make surgery more difficult. Cataract surgery can be undertaken successfully in any season. Summers or rainy season have absolutely no effect on the outcome of the cataract surgery. cataract
Ageing is the most common cause. With age, proteins of the eye lens get altered and opacified leading to cataract. Other causes include congenital and developmental anomalies, trauma, inflammation of the eye, metabolic diseases like diabetes, hypothyroidism, prolonged use of steroids etc. The early cataractous lens bends light irregularly, so the images formed are blurred and unclear. When totally opaque, the cataract cuts off light leading to reversible blindness.
Treatment options for Cataract Surgery is the only course of treatment for cataract. There are options available for cataract surgery :- 1. Conventional Cataract surgery or Extra Cataract Extraction (ECCE) Requires a incision of 10 – 12 mm The cloudy eye lens is removed in one piece A hard plastic lens is implanted Multiple Stitches are required Final glass prescription could take even up to 10 weeks 2. Small Incision Cataract Surgery (SICS) Requires a small incision 3 – 4 mm Cataract is removed manually and foldable IOL is implanted No stitches Heals fast 3. Micro-incision Cataract surgery (PHACOEMULSIFICATION) Requires a very small incision of about 2 mm Cataract Extraction with Phacoemulsification and foldable lens implant Walk-in Walk-out procedure Stitch less, bloodless, painless surgery 4. Femto Laser assisted Cataract Surgery (World’s latest and advanced surgical technique till date) Incision made by Femto Second Laser Machine Blade less, Blood less More precise Cataract Extraction with Phacoemulsification and foldable lens implant Walk-in Walk-out procedure Advantages of Phacoemlusification & Femto Laser assisted Cataract Surgery Stitch less, painless, no bandage surgery. Drops of local anesthesia agent used (for soft cataract) instead of an injection in the eye, thus leading to walk – in walk – out procedure. Minimum curvatural changes occur in the eye following surgery The wound is very secure after surgery. Post Surgery, the wound is very secure. Early visual rehabilition for the patient. Final glasses can be prescribed within 2-3 weeks Intraocular Lenses Available :- Aspheric IOLS These IOLs gives good quality of vision post operative due to the lens design, it also improves the contrast sensitivity of the patient and good night vision. These lenses also filter the harmful UV light and blue light which are said to be harmful to the retina. Toric IOLS These IOLs correct the pre existing corneal astigmatism there by reducing the possibility of spectacle wear for distant vision post operatively. Multifocal IOLs These IOLs provide clear vision for all distances hence almost 90% of the day-to-day activities can be performed without the need for additional glasses. Rarely the patient may experience glare during nights post operatively but usually gets adapted within a few months. Accommodating IOLs These IOLs have flexible hinges that enables them to change focus for different distances hence providing clear distance, intermediate and near vision without glasses.
