| Summary: |
Purpose: To
evaluate the astigmatic effect after phacoemulsification
depending on size and location of incision.
Material and methods: Three groups of 30 patients
each: In 1st group with scleral tunnel incision enlarged
to 6 mm with continuous cross – like suture at 12
o'clock; In 2nd group with 3.2 mm scleral incision
without suture at 12 o'clock; In 3rd group with 3.2 mm
superotemporal incision in clear cornea, no suture.
Postoperative astigmatism was examined by keratometry
after 1 day, 1 week and 1 and 3 months post surgery.
Surgically induced astigmatism was calculated by polar
values method.
Results: After 3 months observation the lowest
mean postoperative corneal astigmatism was achieved in
group III. The SIA was 0.71 in group III, 1.08 in group
I and 0.95 in group II. The differences between group
III and groups I, II were statistically significant.
Conclusions: Surgically induced astigmatism can
be minimized with incision in clear cornea and no suture. |
