| 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the probe is withdrawn and the puncture on the white portion of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.
