Benefits for patients
Cataract surgery by phacoemulsification procedure and foldable intraocular lenses makes its treatment
very comfortable for patients. The patients can resume their normal activity faster as compared to
conventional extra capsular extraction ( ECCE ) cataract eye surgery using
sutures.
The wound heals faster and more predictable and compared to conventional surgery less follow up
visits for checkups are required. Because of the small incision, the use of sutures is not required,
the cornea does not get distorted and risk of significant
astigmatism is minimized.
Phaco procedure
The advantages of phaco surgery
The advantage of cataract surgery by phacoemulsification is the insertion of the intraocular lens through
a small incision, which is self-sealing. After cataract surgery is performed, the wound is more stable
and wound complications are minimized.

Phaco procedure
Cataract surgery
Phacoemulsification cataract surgery was introduced in 1967 by Charles D.Kelman, an American ophthalmologist ( 1930-2004 ). Phaco surgery is a procedure in which the natural lens,
clouded by a
cataract, is broken up by ultrasound, irrigated and suctioned out ( aspiration ).
Cataract surgery by phacoemulsification has gained in popularity in recent years and is now
the preferred form of cataract surgery.
The incision size for phaco surgery
The incision size for phaco surgery is 3.0 - 3.2mm, however foldable iols are in the market which can be
inserted through a 1.6 - 3.0mm incision.
If a lens implant that can be folded is used following removal of the cataract, this incision may not have to
be enlarged. If a conventional
PMMA iol is used, which can not be folded, the incision must be enlarged
to minimal 5.5mm and sutured for closure after insertion of the intraocular lens.
Phaco procedure in modern cataract surgery
The technique of phaco surgery
The technique of phacoemulsification surgery utilizes a small incision.
The tip of the
U/S hand piece instrument is introduced into the eye through this small incision.
Localized high frequency waves are generated through this tip to break the cataract into very tiny
fragments and pieces, which are then sucked out through the same tip in a controlled manner.
A thin 'capsule' or shell is left behind after cleaning up of the entire opaque cataract.
Safe procedure
Although the ophthalmic phaco procedure has been available to us for a long time,
recent advances and refinements in phaco system and micro-surgical instruments
have made the phaco procedure safe and more effective than previously.
Cold Phaco
The new cold phacoemulsification technology reduces risk for patients and may enable better recovery.
Cold phaco systems offer new capabilities that allow surgeons to move up to the next step
in cataract surgery, bi-manual micro-incision phaco surgery.
