Potential acuity meter for predicting visual acuity after Nd:YAG posterior capsulotomy.
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.
