摘要
目的 在白内障囊外摘出并人工晶状体植入术前预测术后的最佳矫正视力。方法 应用Lotmar视力仪预测术前视力大于或等于0.01的18只手术眼,测不出预测值的手术眼测其对侧眼的预测值。结果 预测值小于或等于术后最佳矫正视力,差值在02以内的有11眼(61.1%),r=05858。其余14只手术眼因术前视力小于001,测不出预测值,测其对侧白内障眼的预测值与手术眼术后最佳矫正视力差值在02以内有10眼(714%),相关系数为06520。结论 用Lotmar视力仪预测白内障术后最佳矫正视力较准确,值得推广。
ObjectiveTo evaluate the correlation of the predicted visual acuity of the cataract eyes before operation with their best corrected visual acuity (BCVA) after being performed cataract operation.Methods32 senile cataract eyes without any other ocular diseases were performed extracapsular cataract extraction and intraocular lens implantations.The Lotmar visometer was used to predict their postoperative visual acuities. 18 eyes with visual acuities 0.01 can be measured out the predicted values.The rest 14 eyes with visual acuities 0.01 couldn’t be evaluated with the Lotmar visometer;the predicted values of the contralateral cataractous eyes was used to predict the BCVA of the operated eyes.Their BCVAs were measured within 6 months after operation.ResultsAll the predicted visual acuities were worse than or equal to the postoperative BCVA.Among 18 eyes group,the difference between the predicted visual acuity and the postoperative BCVA was within 0 2 in 11 cases(61 1%, r =0 585*!8).Among the 14 eyes group,the differences between the predicted visions of the contralateral cataractous eyes and the BCVA of the operated eyes were within 0 2 in 10 cases(71.4%, r = 0.652*!0 )ConclusionsThe predicted visual acuities of the uncomplicated cataract eyes measured by Lotmar visometer are very precise compared with their postoperative BCVA.
