摘要
目的研究成功验配渐进多焦点镜片（渐变镜，progressive addition lenses,PALs）的近视患者的年龄与其近附加（presbyopic add，ADD）的关系。方法将本中心2005年1月1日至2008年6月15日间成功验配渐变镜、资料完整的近视验配者69例（双眼均为近视眼,等效球镜〉-0．50 D）．按照每5岁分为一组，共分5组（40～45岁为第1组．46～50岁为第2组，51～55岁为第3组，56～60岁为第4组，61岁及以上为第5组），线性回归分析年龄与最终成功验配的渐变镜近附加的关系。结果随着年龄的增加，近附加逐渐增加，年龄和近附加呈线性回归（t=9．662，P〈0．01），得出公式：近附加=-0．697＋0．051×年龄（年龄≥40岁）。5组患者的近附加分别为（1.44±0．27）D、（1.73±0.32）D、（2.08±0.28）D、（2.38±0.38）D和（2．52±0．38）D，各组之间差异有非常显著的统计学意义（F=21．303，P〈0．01）。结论从昆明地区验配近视眼渐变镜的中老年人近视眼的现状可知，该人群每5年增加约0．25 D的近附加是初步成功验配的基础：
Objective To analyze the relationship between presbyopic add （ADD） and age in those myopes who have successfully worn progressive additions lenses （PALs）. Methods The records for 69 cases of myopes were chosen at the Tianming Optometry Clinics of Kumning, P.R.C, from January 1, 2005 to June 15, 2008, which were retrospectively divided into five age groups based on 5-year intervals （40-45 years, group 1, 46-50 years, group 2, 51-55 years, group 3, 56-60 years, group 4, and equal to or older than 61 years, group 5）. The relationship between ADD and age was analyzed by linear-regression analysis. Results There was a significant relationship between presbyopic add and age, which could be expressed as ADD=-0.697＋0.051 ×age （age≥40 years）. There was a significant difference in presbyopic add between each of the age groups （F=21.303, P〈0.01）. The presbyopic add of group 1 was （1.44±0.27）D, group 2 was （1.73±0.32）D, group 3 was （2.08±0.28）D, group 4 was （2.38±0.38）D, and group 5 was （2.52±0.38）D. Conclusion Presbyopic add increases with age. The rule for successfully wearing PALs is to increase the add by approximately 0.25 D for every 5 years of age.
