Abstract

Purpose: To explore the long-term clinical efficacy of AcrySof toric intraocular lens (IOL) implantation to correct regular corneal astigmatism in cataract patients with axial myopia at primary hospitals.

Methods: A total of 78 cataract patients (78 eyes) with regular corneal astigmatism and axial myopia were enrolled in the retrospective cohort study and were divided into two groups according to axial length (AL) (group 1: 24‒27 mm; group 2: 27‒30 mm). Best-corrected visual acuity (BCVA; in logarithms of the minimum angle of resolution), astigmatism value, and the lens axis deviation (LAD) were determined before and at 3 and 12 months after operation.

Results: BCVA (LogMAR) and residual refractive astigmatism (RAS) at 3 and 12 months after IOL implantation were significantly lower than those before implantation in each group (p < 0.05). The differences of LAD at 3 and 12 months between the two groups were not significant (p > 0.05). The proportion of eyes with LAD exceeding 10° at 12 months was significantly lower in group 1 than in group 2 (p = 0.043). AL was closely correlated with LAD (r = 0.360, p = 0.001), and AL (odds ratio 2.527, 95% confidence interval 1.110-5.751) was a significant, independent risk factor for LAD at 12 months.

Conclusion: These data suggested that implantation of an AcrySof toric IOL is effective for correcting regular corneal astigmatism in eyes with axial myopia and cataract at primary hospitals. AL was an independent risk factor for toric IOL rotation.

环形人工晶状体在基层医院轴型近视伴角膜散光白内障患者中的应用效果。

目的：探讨基层医院白内障伴轴型近视患者行人工晶状体植入术矫正常规角膜散光的远期临床疗效。方法：选取78例（78眼）常规角膜散光伴轴型近视的白内障患者进行回顾性队列研究，按眼轴长度（AL）分为两组(1组：24 ~ 27 mm；组2:27-30 mm)。最佳矫正视力；（最小分辨角的对数）、散光值、晶状体轴偏差（LAD）分别于术前、术后3个月和12个月测定。结果：两组患者人工晶状体植入术后3、12个月的BCVA （LogMAR）、残余屈光散光（RAS）均显著低于植入术前（p < 0.05）。12个月时LAD超过10°的眼比例组1明显低于组2 （p = 0.043）。AL与LAD密切相关（r = 0.360, p = 0.001）， AL（优势比2.527,95%可信区间1.110-5.751）是12个月时LAD的显著独立危险因素。结论：在基层医院行acryysof环形人工晶状体植入术，可有效矫正轴型近视和白内障患者角膜散光。AL是环形人工晶状体旋转的独立危险因素。
