It may help to hold objects closer to the eye to read and do close-up work. The pupil, which is normally black, may undergo noticeable changes in colour and appear to be yellowish to white. Detection and Diagnosis Cataracts cannot usually be seen from the outside of the eye without proper instruments. When a cataract causes loss of sight that interferes with work or lifestyle, it is probably time to have it removed. The patient and the ophthalmologist decide together when removal is necessary, according to individual needs.
Surgery is the only effective way to remove the cloudy lens.
Although rapidly changing technology and research in recent years have improved the treatment of cataracts, eyedrops, ointments, pills, special diets and eye exercises have not been proven to dissolve or reduce a cataract. It is important to understand that complications may occur and, as with any surgery, a good result cannot be guaranteed. Once the cloudy lens of the eye is removed, the patient needs a substitute lens to focus light. There are advantages and disadvantages to each type of lens replacement. The ophthalmologist helps the patient decide which lens or combination of lenses is best suited to the person's lifestyle and will help provide the best vision.
