老视近附加的科学检测和验配的初步分析

An analysis of presbyopic add

目的 :探讨老视近附加的科学检测方法。方法 :随机抽取老视患者 5 7例 ,年龄 40～ 74岁 ,进行客观和规范主观验光 (所有 5 7例 114只眼矫正视力均在 4.9以上并且双眼矫正视力不超过一行 )。然后在双眼基础上用规范方法检测调节幅度、正负相对调节、调节范围等老视眼调节参数 ,结合患者实际阅读需要 ,经充分时间试戴后再确定近附加屈光度。将检测结果与根据年龄计算出来的经验近附加值 ,用统计软件SPSS 11.0进行统计学分析。结果 :实际检测ADD结果与经验值差异有显著性。初步得出一条回归公式 :ADD =- 1.2 1+0 .0 5 0 1·年龄。结论 :临床检测老视近附加应根据实际被测眼的调节参数进行精确的调整和验配 。

Objective:To analyze the exact test for presbyopic ADD.Methods:57 presbyopic patients,aged 40 to 74 years,were enrolled as subjects and underwent objective and subjective refractions(57 cases,114 eyes had corrected visual acuities of ≥4.9 and the differences in visual acuity between the two eyes were no more than one line). Presbyopic accommodation function,including AMP NRA/PRA,and the measurement of accommodation,is normally based on both eyes. The add of the actual tests and theoretical assessments were compared and statistically analyzed with SPSS 11.0.Results:There were significant differences between the ADD of actual and theoretical results.Conclusion:The exact clinical test for an ADD should be based on the actual accommodation of the eyes,and not on subjective assessment.
