This is followed by theinsertion of a thin ultrasound probe in the eye. The probe dissolvesthe clouded lens (phacoemulsify) with the help of ultrasonicvibrations. It then suctions out the tiny fragmented pieces of thelens. After the removal, an artificial lens is placed inside theeye. The whole process is usually completed in less than 30 minutes.It involves minimal sedation, no stitches and no after surgery eyepatch.Extracapsular SurgeryThisprocedure is used for treating advanced stages of the condition thatcannot be cured with phacoemulsification. A 10 to 12 mm long incisionis made inside the sclera or cornea. The larger incision allows thecataract to be removed without getting fragmented. After theirremoval, an artificial lens is positioned inside the eye. However,the visual recovery is comparatively slower than phacoemulsification.Intracapsular Cataract SurgeryThissurgical technique involves the removal of the complete lens and thesurrounding capsule.
