Q. I visited my eye specialist because i thought i needed a change of glasses. He told me i have developed cataract in my eyes! What do i do now?

A. If you are above 50 years, and been in a similar situation, there is nothing to worry about. Cataract or “chhani” or “motiyabind” as it is called in local languages, is one of the most common eye diseases which almost every human being develops in their lifetime. The God-gifted natural lens gradually opacifies with age, causing blurring of vision. Fortunately, the solution is very simple, and a painless one-time surgical procedure is the answer. Cataract surgery is today the most commonly performed surgical procedure in the world, and with the highest success rate.


Q. What is done in a cataract surgery?

A. A cataract surgery is usually performed under topical anaesthesia i.e., only with the help of eyedrops, without use of any injections. The surgeon uses either phacoemulsification or laser to take out the opacified natural lens and replaces it with an artificial intra-ocular lens, suited to your eye. The entire procedure takes 10-15 minutes only.


Q. How do i choose the perfect lens for my eye?

A. Prior to your surgery, there will a comprehensive examination of your eye including cornea, retina, nerve, and pressure of the eyes. A biometry test is done to calculate the power of the lens required for your eye. Based on the results of all these, your surgeon will discuss with you, which lenses would be most suitable for you.


Q. When can i get back to work after a cataract surgery?

A. With today’s modern cataract surgery, you will be ready to get back to work in 2-3 days.


Q. What will be the restrictions after surgery?

A. There are no restrictions on food, and there is no requirement for bed rest. A head bath is allowed after 7 days.


Q. What should i expect on the day of surgery?

A. You will be called to the hospital two hours prior to the surgery for dilatation of pupil and preparation of the eye to be operated. If you have opted for laser cataract surgery, under topical anaesthesia, first the laser treatment of the eye will be performed. This is followed by removal of the cataract using phacoemulsification and implantation of the intraocular implant. You will be in the hospital for a total of 3-4 hours.
