Cataract surgery is the removal of natural lens of the eyes that has turned opaque due to cataract. There are different types of cataract surgery. A very thin ultrasound probe is then inserted into the eye which uses ultrasonic vibrations that dissolve the clouded lens called phacoemulsify. The small fragmented pieces are then suctioned out through the same ultrasound probe.
There are generally three basic techniques for cataract surgery- Phacoemulsification, Extracapsular cataract surgery and Intracapsular cataract surgery. Out of these three, phacoemulsification is the most common type of cataract removal surgery. In this modern method only small incision is required and it is completed in few minutes. Extracapsular cataract surgery is for advanced cataract in which the lens is too dense to dissolve the fragments. This requires large incision so that cataract can be removed without formation of fragments. Intracapsular cataract surgery requires even larger incisions than the previous one. In this the surgeon removes the entire lens along with the surrounding capsule.
