Abstract:
The potential acuity meter (PAM) was designed to evaluate visual acuity in 22 eyes that required secondary capsulotomies. The PAM prediction was within one line in 13 eyes (59%) and within two lines in 17 eyes (77%) and had an 18% rate of falsely bad prediction (more than two lines) and 5% rate of falsely good prediction for YAG capsulotomy. In aphakic patients, however, further study is necessary.
