Abstract Details

Purpose:

To discover and analyze prevalence of corneal astigmatism among Ukrainian people (Caucasian race) who potentially need treatment of cataract by implantation of toric intraocular lenses.

Setting:

Center Eye Microsurgery and Laser Treatment (one day), Kiev Regional Clinical Hospital, Kiev, Ukraine.

Methods:

1557 eyes of 782 patients (307 males and 475 females) were examined. Average age was 53.5 years. Keratometry was done with autorefkeratometer TOPCON KR 8800. Depending on the degree of astigmatism patients were divided into five groups. First group – no astigmatism; second group – astigmatism 0.12–0.75 D; the third group – astigmatism 0.87–3 D; the fourth group – astigmatism 3.12–6 D; the fifth group – astigmatism from 6.25 D and higher.

Results:

In the first group (0.64% of cases) astigmatism was not diagnosed. The second group included 55.94% of patients (0.12–0.75 D) with average degree 0.48±0.19 D ax 97±64°. The third group (0.87–3 D) with average degree of astigmatism 1.31± 0.08 D ax 102±57 included 41.23% of patients. The fourth group (3.12 – 6 D) got 1.99% of examined patients with average degree of astigmatism 4.05±1.15 D ax 97±64°. Astigmatism from 6.25 D and higher was observed in 0.19% of cases (the fifth group) where the average measurements were 6.54±0.08 D ax 110±19º.

Conclusions:

Therefore among Ukrainian people, who belong to Caucasian race, corneal astigmatism occurs in 99.35% of cases. With probable surgery of cataract, 43.41% of examined people with significantly high degree of astigmatism require its correction by implantation of toric intraocular lenses.
