Question 4

Describe the procedure of cataract surgeries:

Answer 4

• 3mm corneal incision allows the insertion of IOL
• removal of circular portion of the anterior capsule which creates an aperture from which the lens is removed and the iol is inserted
• the remaining capsule supports the IOL
• the phaco probe is inserted
• the probe emits ultrasonic radiation which allows for the nucleus to be broken up into smaller pieces and it combines with aspirating fluid hence emulsification
• the probe then vacuums out the lens fragments
• then the soft nucleus is removed by suction
• the phaco probe is removed and iol is inserted via a needle and unfolds and gets shaped over the pupil being held by haptics in the equator region
