Abstract:
To evaluate the prediction of visual outcome in cataract patients, the authors compared the preoperatively measured vision using hand-held laser interferometry(HEINE LAMBDA 100, GERMANY) and Han's visual acuity chart with the postoperatively corrected vision. Among 40 patients, in the 12 cases with immature cataract and normal macula, the postoperative measured acuity was predicted within two lines in 7 cases(58%), and in the 27 cases with mature cataract including nuclear sclerosis, the disparity under -2 was only 6 cases(21%). In the 6 cases with macular abnormality, one patient showed positive disparity. These results indicate that the prediction of visual outcome for catarct sugery using the hand-held laser interferometer was reliable in immature catarct with normal macula.
