检眼排镜在视力检查中的可行性探讨

The Available Discussion on the lens-arranging for Eye-Checking in the Vision-checking

目的探讨视力检查的方法，改进和提高视力测量的准确性。方法对225名学生视力不超过4．3的438只眼睛同时应用传统法、变距法、检眼排镜法进行视力检测和比较。结果4．0～4．3视力组，传统法（4．12±0．10）、变距法（4．11±0．16）分别与检眼排镜法（4．01±0．14）进行比较，差异均有统计学意义（由〈0．01）；4．0以下视力组，传统法（3．82±0．09）、检眼排镜法（3．80±0．15）分别与变距法（3．89±0．14）进行比较，差异均有统计学意义（p〈0．01）；4．0以下视力组经2．5m变距法校正后视力达到4．0～4．3者占26．85％，而检眼排镜法仅为12．04％，后者较符合受检者的实际视力。结论检眼排镜法是检查视力既简便又准确的一种方法，对4．0以下的视力的检查，检眼排镜法优于变距法和传统法。

Objective Aim at the improvement of vision-checking manners and improving the exactness of vision measuring. Method The authors check and compare the vision of the 438 eyes of 225 students in Yulin Normal College whose vision is ≤4.3 by means of traditional means, distance-changing, lens-arranging. Results the 4. 0-4. 3 vision group has very noticeable differences in the traditional means （4. 12±0. 10）, lens-arranging （4.11±0.16）, distance-changing; （4.01±0.14） vision 〈4.0 group also has very noticeable differences in the traditional means （3.82 ± 0.09）. Lens-arranging （3.80 ± 0.15）, distance-changing （3.89 ± 0.14）. Conclusion Lens-arranging is simple, exact in vision-checking and for the vision 〈4.0 group, lens-arranging is superior to distance-changing.
