  1. Cataract ArchithaDevati p.3

  2. Basic Overview

  3. Lens = part of the eye that focuses light on the retina

  4. Types of Cataracts • Old Age • Lens is made of water and protein • Protein clumps together and clouds the lens • Secondary Cataract • Form after surgery for other eye problems • Health problems, such as diabetes • Congenital Cataract • Traumatic Cataract

  5. Risk factors • Smoking • Excessive UV-light exposure • Diabetes • Use of certain medications • Oral, topical, or inhaled steroids

  6. Symptoms • Cloudy or blurry vision. • Colors seem faded. • Glare. Headlights, lamps, or sunlight may appear too bright. A halo may appear around lights. • Poor night vision. • Double vision or multiple images in one eye. (This symptom may clear as the cataract gets larger.) • Frequent prescription changes in your eyeglasses or contact lenses.

  7. Detection • Visual Acuity Test • See how well your vision is from various distances • Dilated Eye Exam • Use a slit lamp bio-microscope • Dilate the pupils and then observe retina and optic nerve for signs of damage

  8. Treatment • No medical treatment will prevent or reverse the cataracts • Surgery is the only remedy • Surgery ends with removal of lens and replaced with an artifical lens (an IOL: intraocular lens) • Types of Surgery • Phacoemulsification: Most common type of surgery today • Extracapsular: Remove the lens in one piece
