Eye Operation-By Phaco Emulsification Technique
Phaco – emulsification:
Phaco- emulsification is the technique by which cataract is broken into small pieces and removed from the eye using ultrasound with the help of a special phaco equipment. The actual cataract operation is carried out through a 2.5 to 2.8 mm incision with the help of a titanium needle vibrating at the rate of more than 40,000 times per second.
In early (small incision-SICS) days routine cataract operation is carried out through an incision which is 5 to 6 mm in length through which first cataract is removed and then an intraocular lens is implanted. In Phaco- emulsification technique, cataract removal is done through 2.8 mm opening for implantation of the intraocular lens and this avoid the necessary for stitches to close the wound and reduce the amount of glasses required for distant vision.
Benefits of Phaco surgery:
- No hospitalization - Walk in, Walk out surgery.
- Smaller incision- hence lesser complications related to the incision size.
- Lesser induced astigmatism because of smaller incision.
- No restriction on normal activities. Can join work from next morning.
- Fast recovery of good vision in a matter of days.
- Final spectacles at one or two weeks.
- Early visual rehabilitation.
