方法：应用LAMBDA100视网膜计测定91例91眼高度轴性近视白内障患者的患眼视网膜视力，与术后2wk最佳矫正视力进行比较。预测视力与术后视力相差2行对数视力表以内为符合。

结果：患者91例91眼预测的总符合率为62%，假阳性率2%，假阴性率36%。晶状体混浊度影响预测准确性，混浊愈重，准确度愈低。眼轴≥32mm预测准确度明显低于眼轴<32mm预测准确度，两组比较有统计学差异(P<0.05)。术前最佳矫正视力≥4.0组预测准确率为75%，最佳矫正视力<4.0组为49%，两组比较有统计学差异(P<0.05)。

结论：对合并非成熟性白内障的高度近视患者，LAMBDA 100可以作为预测术后视力的辅助工具，眼轴、术前视力和白内障程度会影响预测的准确度。

METHODS: The retinal visual acuity was measured in 91 patients with 91 cataract eyes by LAMBDA100, and compared with the best corrected visual acuity 2wk after operations. If differences of predictive visual acuity and postoperative visual acuity between the two logarithmic visual acuity chart was within 2 lines, it was considered consistent.

RESULTS: The total compliance rate was 62%, the false positive rate was 2%,the false negative rate was 36%. The predictive accuracy was affected by lens opacity, the deeper opacity, the lower accuracy. The predictive accuracy of eye with axial length ≥32mm was significantly lower than that of eye with axial length <32mm, the difference was statistically significant(P<0.05). The predictive accuracy rate of group that preoperative best corrected visual acuity was ≥4.0 was 75%; the predictive accuracy rate of group that preoperative best corrected visual acuity was <4.0 was 49%, the difference was statistically significant(P<0.05).

CONCLUSION: LAMBDA100 can be used as an assistant tool for predicting postoperative visual acuity in immature stage cataract of patients with high myopia. The eye axial length, the degree of visual acuity and lens opacity can influence the predicting accuracy.
