title: Efficacy of laser interferometry in predicting visual result of YAG laser posterior capsulotomy.
abstract: One hundred fifteen patients with cloudy posterior capsules that required capsulotomies were evaluated by laser interferometry. The predicted acuity was within one line of postoperative acuity in 44 patients (38.3%) and within two lines in 73 patients (63.5%). The correlation coefficient between the predicted and actual post-capsulotomy acuities was 0.38. However, the predicted retinal visual acuity was compared to postoperative Snellen visual acuity and found to differ by an average of three lines. A large number of false negative results reduced the clinical usefulness of the test.
