Cataract Extraction with IOL (Intra Ocular Lens ) Implantation
MODERN TECHNIQUES
1. Standard IOL Microsurgery

2. Small Incision Cataract Surgery with IOL implantation (Sutureless)

3. Phaco Emulsification Surgery with IOL Implantation (Sutureless)
IOL Microsurgery - with sutures
Step : 1 An incision is made just above the cornea.
Step : 2 The surgeon penetrates the eye through the incision and removes or peels off the front portion of the cataracted lens.
Step : 3 The whole cataract is then removed.
Step: 4 The rermning capsule or the bag is cleaned
Step: 5 An IOL (Intra Ocular tens) is implanted inside the bag.
Step: 6 The incision is then closed with very fine sutures.
SICS : SMALL INCISION CATARCT SURGERY - without sutures.
STEP : 1 A very small incision is made just above the cornea
STEP: 2 A self sealing tunnel is prepared through the incision.
STEP:3 The remaining steps are like in IOL Microsurgery. No
          stitches are required as it is a self sealing minute incision.
PHACOEMULSIFICATION CATARACT SURGERY- without sutures

A phaco machine with a probe is used for cataract extraction and IOL implantation . This is a Sutureless surgical procedure.

  • STEP: 1 The probe is used to puncture a hole on the white portion of the eye (Sclera), just above the cornea., or in the cornea.
  • STEP :2 The phaco probe is then used by the surgeon to reach the front portion of the cataracted lens
  • STEP: 3 A circular tear is made on the front portion of the cataracted lens.
  • STEP :4 With another ultrasonic hollow probe, the cataract is broken into tiny fragments, which are then sucked out of the bag .
  • STEP : 5 The remaining capsule or bag is then cleaned and a sterile foldable lens is inserted through the hollow probe into the capsule, thus replacing the cataract with a crystal clear lens.
  • STEP : 6 Finally the probe is withdrawn and the puncture on the white portion of the eye seals itself automatically.
COLD PHACO
All the steps in this procedure are the same as in phaco emulsification surgery . Here, A cold phaco machine with a probe, which produces minimum heat, is used. The chances of corneal damage are considerably less.
PHACO WITH RIGID LENS

All the steps in this procedure are the same except that instead of a foldable lens, a rigid lens is inserted into the lens capsule through the hollow probe.

ADVANTAGES OF PHACO

  • Early rehabilitation .
  • Less cylindrical power with glasses.
  • Eye remains safe even in case of minor accidental post operative trauma.


CONTRA-INDICATIONS OF PHACO

  • Poor corneal health.
  • Very big and hard Cataract.
  • Cataract displaced from its original position .
  • The eye having any other pathology.
