How can a slit-lamp exam help in the diagnosis of cataracts?

ANSWER

This uses a special microscope with a bright light that lets your doctor check different parts of your eye. She'll look at your cornea -- the clear, outer layer. She'll also examine the iris -- the colored part of your eye -- and the lens that sits behind it. The lens bends light as it enters your eye so you can see things clearly.
