Diagnosis of Cataracts
- Visual Acuity Test—This eye chart test measures how well you see at various distances. This may include a test of your vision under conditions of low contrast and/or glare.
- Slit Lamp Exam—This is an examination of the eye using a specialized microscope that magnifies the eye.
- Tonometry—This is a standard test to measure fluid pressure inside the eye (increased pressure may be a sign of glaucoma).
- Dilated Eye Exam—The doctor gives you special eye drops to widen your pupil, which allows better examination of the lens and the structures of the back of the eye. This allows your doctor to examine the lens in more detail to detect a cataract.
