PLANNING FOR CATARACT SURGERY

ARE YOU A CANDIDATE FOR CATARACT SURGERY?

Almost anyone who has cataracts and who is in reasonably good health, regardless of age, can have cataract surgery. Here are a few things to keep in mind, however:

• Remember that cataract surgery corrects only cataracts and won't fix other eye problems
• Ask your doctor how well you can expect to see after lens replacement if you have macular degeneration, diabetes, glaucoma, extreme nearsightedness, or very small pupils.
• Replacing the clouded lens with a clear one might well improve your eyesight, just as a clear camera lens will give you a sharper photograph than a scratched or blurry lens
• But if your retina is damaged, it's like having defective film in your camera
• Depending on the type of damage, cataract surgery might or might not help.

• They are at greater risk 57 Planning for Cataract Surgery for retinal detachment, macular disease, and inflammation than other cataract-surgery patients

• If you take blood-thinning medication-aspirin or warfarin (Coumadin), for example- talk with your doctor about the type of surgery you'll be having
• You won't have to stop taking blood-thinning drugs if you are having the clear-corneal phacoemulsification procedure (described later in this chapter), in which there is no bleeding.
• Don't expect the impossible
• In all likelihood, you'll be delighted with the improvement in your eyesight after you've adjusted to your new lenses-as long as you don't expect to see as well as you did in your teens and twenties.
