Treatment of Cataract (Motiya)
Dr. Waseem Khan, Riyadh

 Assalam  Alaikum to every one!  In this issue I’ll tell you about the treatment of “cataract”.
 So that early treatment can save your precious eyes. Read it and say “Bye! Bye!” to cataract
.
Cataract is detected through a comprehensive eye exam that includes
:

v      “Visual acuity test”,

v      “Dilated eye exam” and

v      “Tonometry”.

If you have early cataract symptoms, then wearing a new power eyeglasses or anti-glare sunglasses, or magnifying lenses might help you to see a little clearer. If these measures do not help and vision loss interferes with your everyday activities, such as driving, reading, or watching TV, then surgery is the only effective treatment. Don’t be afraid with the name of surgery because now a days surgery of eyes is more safest then ever. In cataract surgery, surgeon just removes the cloudy lens and replaces an artificial lens at same place. Sometimes a cataract should be removed even if it does not cause problems with your vision. For example, a cataract should be removed if it prevents examination or treatment of another eye problem, such as age-related macular degeneration or diabetic retinopathy. The surgery on each eye will be performed at separate times, usually four to eight weeks apart.      Many people who need cataract surgery also have other eye problem with cataract, such as glaucoma (“kala pani” in Urdu language). If you have other eye conditions in addition to cataract, talk with your doctor. Learn about the risks, benefits, alternatives, and expected results of cataract surgery.
There are two types of cataract surgery. Your doctor can explain the differences and help determine which is better for you, “Phacoemulsification” (Phaco). In this procedure a small incision is made on the side of the cornea ( the clear dome-shaped surface that covers the front of the eye). Your doctor inserts a tiny probe into the eye. This device emits ultrasound waves that soften and break up the lens so that it can be removed by suction. Most cataract surgery today is done by “Phacoemulsification”. It is also called "small incision cataract surgery”. Other one is  “Extracapsular surgery”. In this your doctor makes a longer incision on the side of the cornea and removes the cloudy core of the lens in one piece. The rest of the lens is removed by suction. After the natural  lens has been removed, it often is replaced by an artificial lens, called an “Intraocular lens” (IOL). An IOL is a clear, plastic lens that requires no care and becomes a permanent part of your eye. As with any surgery, cataract surgery poses risks, such as infection and bleeding. Before cataract surgery, your doctor may ask you to temporarily stop taking certain medications that increase the risk of bleeding during surgery. After surgery, you must keep your eye clean, wash your hands before touching your eye, and use the prescribed medications to help minimize the risk of infection. Serious infection after Cataract surgery slightly increases your risk of “Retinal detachment” in which retina (most sensitive part of eye) will detach from its wall. One sign of a retinal detachment is, a sudden increase in flashes or floaters in eyes. Floaters are just like you’ll feel mosquitos flying in front of your eye. If you notice a sudden increase in floaters or flashes, you must see an eye doctor immediately.
 
A retinal detachment is a medical emergency.
After cataract surgery, gradually you will loose your vision and you feel that again you have cataract, but don’t worry it is a  normal growth of your eye tissues and it only happens sometime, that eye tissues encloses the artificial lens(IOL) and the lens becomes cloudy and it blurs your vision. This condition is called an after-cataract. An after-cataract can develop months or years after cataract surgery. An after-cataract is treated with a laser. Your doctor uses a laser to make a tiny hole in the eye tissue behind the lens to let light pass through this hole. This procedure is called a “YAG Laser Capsulotomy”. It is painless procedure and doctor can perform it in room not in operation theatre. When your eye heals, you may need new glasses.
