Abstract
AlM: To analyze the prevalence and presentation patterns of corneal astigmatism in cataract surgery candidates of Shenyang in northeast China. <br> METHODS:A retrospective survey was used to study the corneal astigmatism which were measured by intraocular lens( lOL) Master optical biometer before cataract surgery between Jan. 1st, 2014 and Dec. 31st, 2014. Descriptive statistics of corneal astigmatism data were analyzed. <br> RESULTS:The keratometric data from 4 543 eyes from 3821 patients with a mean age of 66. 36±10. 38y(SD). ln 10. 50% of eyes, corneal astigmatism was between 0. 5 diopters(D) or less;in 30. 05% of eyes, it was 0. 5-1. 0 D;in 23. 60%, it was 1. 0-1. 5 D;in 13. 19%, it was 1. 5-2. 0 D;in 7. 68%, it was 2. 0-2. 5 D;in 6. 41%, it was 2. 5-3. 0 D;in 8. 58%, it was 3. 0 D or higher. With-the-rule astigmatism was found in 27. 69% of eyes, while against-the-rule was found in 53. 84% of eyes. <br> CONCLUSlON:About 59. 46% of eyes in this study had preoperative corneal astigmatism equal to or above 1. 0 D. Findings indicated more surgical techniques or toric intraocular lenses to meet the potential demand of the cataract surgery candidates.关键词
