Maximal mydriasis evaluation in cataract surgery.

We propose the maximal mydriasis test (MMT) as a simple and safe means to provide the cataract surgeon with objective and dependable preoperative information on the idiosyncratic mydriatic response of the pupil. The MMT results of a consecutive series of 165 eyes from 100 adults referred for cataract evaluation are presented to illustrate the test's practical applications and value. The results enable the surgeon to anticipate problem eyes preoperatively so he or she can plan an appropriate and effective surgical strategy. The MMT has also improved out cost-effectiveness by cutting down unnecessary delays in the operating room and enabling better utilization of restricted costly resources.
