| Summary: |
The study evaluates amount and direction of postoperative
astigmatism after usually performed techniques of cataract surgery.
Material and methods: 90 consecutive patients (120 eyes) mean aged
74,5years, who underwent cataract surgery with clear corneal superior (Group 1) or
temporal incision (Group2), sclero-corneal tunnel sutureless incision (Group 3) or limbal
ECCE incision with x sutures (Group4), were examined with respect to postoperative
astigmatism. Anterior chamber opening was determined by primary astigmatism and nucleus
hardness. All measurements were performed based on keratometry.
Results: The highest mean value of with the rule astigmatism was assessed
in Group 4. From the other hand, the least value were determined in group2- 95% with the
rule and 5% oblique and in group 1- 40% with the rule, 40% against the rule 20 % oblique.
In group 3, the value of postoperative astigmatism was higher, as compared with Group 1
and 2. It was assessed with similar proportion as in Group 1.
Conclusions: At present cataract surgery techniques are not free of
induced astigmatism. Study demonstrates significance of preoperative primary astigmatism
assessment, with respect to surgery technique, to avoid postoperative astigmatism. |
