Cataracts

What is a cataract?
It is when the clear lens in your eye becomes cloudy resulting in blurry vision. Cataracts generally occur in the aging population, but can also be found in young patients and even newborns!

Commonly, cataracts are due to aging changes. However, other factors such as excessive exposure to ultraviolet light (UV), systemic conditions or certain medications like steroids can increase the risk of cataract development. So the best method of preventing early or slow down the progression of cataract formation is to wear sunglasses to protect the lens in your eyes from harmful UV rays.

What are the signs and symptoms of cataracts?
A common sign that patients mention is a constant film over their eyes. This blur in vision cannot be improved with prescription change and it will gradually deteriorate over the years. You will find good lighting for reading to be helpful, night driving may become more difficult, and colours will not appear as vibrant.

In the early stages of cataract, vision is generally not greatly affected. Your Optometrist will monitor the cataract and on occasion, the prescription can change due to the cataract. Once the cataracts begin to interfere with your daily activities like driving or affect your quality of life, your Optometrist will refer you to a surgeon to have them surgical removed.

What happens after cataract surgery?
If you wore glasses before the surgery, it will no longer allow you to see clear anymore because your prescription has changed. The old cloudy lens is replaced by an intraocular lens implant. This lens implant can provide good distance vision without the need of glasses, but you may still need reading glasses. There is also the option to upgrade the lens implant, so that you will have overall good vision without any glasses. About four weeks after the cataract surgery, your Optometrist will check your prescription and evaluate what the new lenses should be to optimize the “new” vision you have!
