How To Treat Different Types Of Cataracts
If you are over 40 and you notice the drastic vision loss, you may have a cataract in your eyes. A cataract is when the eye’s natural lens is clouded. The natural lens of the eyes is behind the iris and the pupil. Cataract is very common among middle-aged people. It is also a leading cause of blindness in the world. There are more cases of cataract formation compared to glaucoma and macular degeneration. Cataracts affect 22 million Americans that are age 40 and above. By 2020, the Prevent Blindness America says there will be over 30 million Americans that will have cataracts.
The Different Types Of Cataracts
There are three different types of cataracts. The first is called the subcapsular cataract and it is formed behind the natural lens. People taking high dose of steroid medicines, high farsightedness and diabetic are at great risk of developing this cataract. The second type is called nuclear cataract and it forms in the nucleus of the lens. The common cause of this cataract is aging. The last type is called cortical cataract; it occurs in the natural lens cortex.
Treatment For Cataracts
When a person has cataracts, it is important to get it removed as it can lead to blindness if left untreated. At the first sign of cataract, you can still use eyeglasses, visual aids and strong bifocals to improve your vision. If your vision gets worse, it is time to get surgery and get the cataract removed. Some people decide to leave the cataract as it is part of aging but poor vision can greatly affect daily life.
Cataract surgery is a simple and relatively painless process to help you regain your vision. It is a common procedure in the U.S. with about 3 million people undergoing it every year. When you undergo cataract surgery, your vision can go back to 20/20 or 20/40. The eye surgeon will remove the clouded lens in your eye and will replace it with a clean and plastic intraocular lens.
