摘　　要：目的探讨白内障患者年龄与人工晶状体（IOL）屈光度预测误差的关系。方法前瞻性非随机队列研究。对拟行晶状体超声乳化术并植入单片式丙烯酸IOL的连续病例525例（525眼）的资料进行分析。按照年龄进行分组，其中≤59岁组75例（75眼），60～69岁组、70～79岁组和80—89岁组各150例（150眼）。利用优化的SRK／T公式测算所需IOL的屈光度。于术后3个月用自动验光仪进行客观验光。比较各年龄组间平均预测误差和绝对预测误差。结果各年龄组间，SRK／T公式预测的平均术前屈光度的误差差异无统计学意义（P=0．418）。≤59岁年龄组，平均预测误差是-0．24D。60～69岁年龄组为-0．17D，70—79岁年龄组为-0．11D，80～89岁年龄组为-0．11D。各组间平均绝对预测误差差异无统计学意义（P=0．619）。平均预测误差与年龄呈正相关（P=0．000）。多元回归分析显示，在预测误差方面，眼轴长度、平均角膜曲率以及前房深度与年龄差异的预测因子无关。结论年龄每增加10岁，预测误差减少约0．06D的近视。提示在选择人工晶体屈光度时，应该考虑到患者的年龄。Objective To investigate the relationship between intraocular lens （IOL） diopter prediction error （PE） and ages of patient with cataract . Methods A prospec ive nonrandom cohort study. The data of 525 eyes of 525 patients with cataract were collected and they were divided into 4 groups according to age. Age ~〈 59 years group were in 75 eyes of 75 cases, and 150 eyes of 150 patients in each other 3 groups （60-69, 70-79 and 80-89 years）. All cases received phacoemulsification and implantation of a single-piece acrylic IOL. The IOL diopter was calculated by the optimized SRK/T formula. Objective refraction was measured with an auto-refractomer 3 months postoperatively. The mean PE and absolute PE were compared among 4 groups. Results The difference of mean preoperative refractive prediction error by the SRK/T formula was statistically significant among 4 groups （P = O. 418）. Mean PE was O. 24 diopters （D） in~〈59 years group,0.17 D in 60-69 years group,O. 11 D in 70-79 years group, and 0.05 D in 80-89 years group. The difference in median absolute PE was not statistically significant among groups （P = O. 619）. Mean PE was positively correlated with age （P = 0.000）. Multiple regression analysis revealed that age, preoperative axial length, average corneal curvature, and anterior chamber depth were independent predictors of the age-related difference in PE. Conclusion PE is less of 0. 06 D per decade as age increased, suggesting that age of patient should be considered when selecting IOL diopter.
