Cataract surgery is an operation to remove your eye's natural lens when it is cloudy. The purpose of the lens is to bend(refract) light rays that enter the eye to help you see. Your own lens should be clear, but with a cataract, it is cloudy.
If you want to get the best experience from your ophthalmologist, coming prepared is key. Clear communication about your medical history and current problems will help ensure that you get the right care.
