Phacoemulsification cataract surgery
is the technique by which cataract is broken into small pieces and removed from the eye using an ultrasonic device, to restore clear vision.
The cataract removal is done through 2.5 to 2.8 mm incision and this avoid the necessary for stitches to close the wound. Formerly the most popular cataract surgery, the older method of extracapsular extraction involves a longer incision (10 mm), or almost half of the eye.
- Anesthesia- Anesthetic can be given with simple topical eyedrops or by injection into the retrobulbar muscle
- The surgeon makes a tiny cut in the cornea
- A small probe that emits ultrasound waves break the affected lens into pieces.
- These pieces are then liquified and sucked out.
- The insertion of an intraocular lens (IOL) usually immediately follows phacoemulsification. The replacement lens is usually curled up in an injector and injected through the cut in the cornea. When it is in place, it unfolds itself and adopts the natural position of the old lens.
