A cataract is a common eye disorder, which occurs when the clouding of the normally clear, natural crystalline lens of the eye. This clouding process will progress, until eventually there is a complete loss of vision. Neither diet nor laser treatment will make the cataract go away because this is a natural process of aging. An ophthalmologist (eye surgeon) can diagnose cataracts during a routine eye exam and determine if eye surgery is necessary. Fortunately, cataract surgery can help restore your vision, long before you experience a loss of vision significant enough to interfere with your daily activities.
