摘要
目的:评价视网膜视力计(retinometer)在预测白内障手术后视力的价值。方法:随机选择各类白内障患者93例106眼,术前采用LAMBDA100视网膜视力计检测患者的预测视力,与术后3mo矫正视力相比较。结果:106眼中12眼(11.3%)术前预测视力与术后视力一致,69眼(65.1%)术后视力好于预测视力(假阴性),25眼(23.6%)术后视力低于预测(假阳性)。结论:视网膜视力计对判断非致密非成熟期白内障的术后视力具有较高的准确性,不同的眼病存在假阴性和假阳性情况,可为术中植入不同类型的人工晶状体提供依据。
AIM： To evaluate a retinal visual acuity meter （retino- meter） in predicting the value of visual acuity after cataract surgery. METHODS： Ninety-three patients （106 eyes） with various types of cataract were randomly selected, preoperative visual acuity tested by LAMBDA 100 retinometer in patients was compared with postoperative 3 months corrected visual acuity. RESULTS： Of 106 eyes, 12 （11.3%） had equal preo- perative predicted and postoperative visual acuity, 69 （65.1%） had better visual acuity than predicted visual acuity （ false-negative）, 25 （ 23. 6%） had postoperative visual acuity lower than predicted （false-positive）. CONCLUSION： LAMBDA 100 clinical detection of retinal visual acuity meter has an excellent result in determining the non-dense non-mature cataract with high accuracy. The existence of false-negative and false-positive cases in different eyes provides a basis for intrao-perative implantation of different intraocular lens.
