To evaluate the characteristics of postoperative refractive status in age-related cataract patients with shallow anterior chamber and the correlation between pre-operative anterior chamber depth and postoperative refractive status.
Prospective case-control study. Sixty-eight cases (90 eyes) with age-related cataract were recruited from October 2010 to January 2012 in People's Hospital Peking University including 28 cases (34 eyes) in control group and 40 cases (56 eyes) in shallow anterior chamber group according to anterior chamber depth (ACD) measured by Pentacam system. Axial length and keratometer were measured by IOL Master and intraocular lens power was calculated using SRK/T formula. Postoperative refraction, ACD and comprehensive eye examination were performed at 1 month and 3 months after cataract surgery. Using SPSS13.0 software to establish a database, the two groups were compared with independent samples t-test and correlation analysis were performed with binary logical regression.
The postoperative refractive deviation at 1 month were (-0.39 ± 0.62) D in control group and (+0.73 ± 0.26) D in shallow anterior chamber group respectively which present statistical significance between the two groups (P = 0.00, t = 3.67); the postoperative refractive deviation in 3 month was (-0.37 ± 0.62) D in control group and (+0.79 ± 0.28) D in shallow anterior chamber group operatively which present statistical significance between the two groups (P = 0.00, t = 3.33). In shallow anterior chamber group, with the shallower of ACD, the greater of refractive deviation (P = 0.00, r1 month = -0.57, r3 months = -0.61).
Hyperopic shift existed in age-related cataract patients with shallow anterior chamber and the shallower of ACD was, the greater of hyperopic shift happened.
评估浅前房年龄相关性白内障患者术后屈光状态特点以及术前前房深度与术后屈光状态之间的相关性。
前瞻性病例对照研究。2010年10月至2012年1月在北京大学人民医院招募68例（90只眼）年龄相关性白内障患者，根据Pentacam系统测量的前房深度（ACD）分为对照组28例（34只眼）和浅前房组40例（56只眼）。使用IOL Master测量眼轴长度和角膜曲率计，并使用SRK/T公式计算人工晶状体度数。白内障手术后1个月和3个月进行术后验光、ACD及全面眼部检查。使用SPSS13.0软件建立数据库，两组采用独立样本t检验进行比较，并采用二元逻辑回归进行相关性分析。
对照组术后1个月屈光偏差为（-0.39±0.62）D，浅前房组为（+0.73±0.26）D，两组间差异有统计学意义（P = 0.00，t = 3.67）；术后3个月对照组屈光偏差为（-0.37±0.62）D，浅前房组为（+0.79±0.28）D，两组间差异有统计学意义（P = 0.00，t = 3.33）。在浅前房组中，ACD越浅，屈光偏差越大（P = 0.00，r1个月 = -0.57，r3个月 = -0.61）。
浅前房年龄相关性白内障患者存在远视漂移，且ACD越浅，远视漂移越大。
