Cataract is a common problem of old age. In this condition the normal crystalline lens of the eye starts getting cloudy, resulting in blurred vision. This leads to difficulty in day to day activities as reading, writing, watching TV, recognizing faces at a distance, reading signboards from a distance etc. Though age is the main cause of cataract, diseases like Diabetes can hasten the onset of cataract.
Certain eye conditions like chronic inflammation of the eyes, retinal detachment, glaucoma, long term use of steroid drops, injury to the eye, increases the chance of cataract development at an early age. Once the cataract sets in there is no medical treatment for it. Treatment is usually in the form of surgery which involves removal of the cataractous lens and implantation of an artificial lens.
Cataract surgery involves removal of the natural lens. We perform advanced cataract surgeries and choice of premium intraocular lenses is available for patients. If both eyes need surgery, it can be planned within a span of few days.
The standard procedure is Phacoemulsification. A small pen like probe is introduced in the eye and using ultrasonic energy, the hard part of the cataract called Nucleus is emulsified or broken down into very fine pieces and sucked out of the eye. Then the remaining soft part is just sucked out of the eye. Once the cataract is cleared then an Intraocular lens is introduced in the eye in a folded manner through the original opening. This lens then unfolds in the eye. As the wound is small, it heals fast. The patient can get back to his routine in 7 days. It is advisable to avoid hectic activities and outdoor jobs for the first week.
Here in Dr. Korade Eye Hospital, phacoemulsification is done using AMO SOVEREIGN WhiteStar system with advanced Fx Ellips technology.
Use of Intra ocular lens is now a standard of care for Cataract surgery. The commonest type of Intra ocular lens is a unifocal lens which focuses images of distant objects on to the back of the eye and hence glasses are needed only for reading. The other type of lens is called multifocal lens which focuses the distant, intermediate and near objects on the back part of the eye. Hence you do not need glasses for most common activities.
