目得：分析和量化等待白内障手术的患者的角膜散光模式，并确定医院单位对复曲面人工晶状体（IOL）的需求。前瞻性地收集和分析所有参加预评估诊所的患者在4个月内的角膜曲率测量结果。该研究包括746例患者的1230只眼，平均年龄为75.54岁± 0.71岁（SD）。角膜散光≤ 0.50D者301眼1.50D以下者978眼，占24.47% D ≥ 2.50者57眼，占79.50%（4.61%），3.00D或以上者24只眼结论：在单个中心的常规白内障手术患者中，497例（40.41%）散光大于1.00 D。研究结果可帮助医院分析散光矫正型人工晶状体的需求和成本。
PURPOSE: To analyze and quantify the pattern of corneal astigmatism in patients awaiting cataract surgery and to establish the demand for toric intraocular lenses (IOLs) in a hospital unit.SETTING: Singleton Hospital Abertawe Bro Morgannwg University NHS Trust, Swansea, United Kingdom.DESIGN: Cross-sectional study.METHODS: Keratometric measurements of all patients attending the preassessment clinic over a 4-month period were prospectively collected and analyzed.RESULTS: The study comprised 1230 eyes of 746 patients with a mean age of 75.54 years +/- 0.71 (SD). The corneal astigmatism was 0.50 diopter (D) or less in 301 eyes (24.47%), 1.50 D or less in 978 eyes (79.50%), more than 2.50 D in 57 eyes (4.61%), and 3.00 D or more in 24 eyes (1.93%).CONCLUSIONS: Of patients attending for routine cataract surgery at a single center, 497 (40.41%) had more than 1.00 D of astigmatism. The results can help hospitals analyze the demand for and cost of using toric IOLs in patients with corneal astigmatism.
