When pre-operative acuity is better than 20/200, the following studies and abstracts conclude the following levels of correlation for predicting postoperative acuity prior to cataract surgery (predicts within 2 lines in 95% and within 1 line in 85% when preoperative acuity is better than 20/200) or YAG laser capsulotomy (predicts postoperative acuity to within 1 lines in 97% and within 2 lines in 100% of eyes when the preoperative acuity is better than 20/200.)
