A Vision Test: Pam (potential acuity measurement) is a vision test to determine the outcome of cataract surgery in patients with other eye conditions. The purpose is to help guide the surgeon and patient in deciding the benefit of cataract surgery. So, if a patient has a moderate cataract and moderate macular degeneration, a pam testing can be performed to predict the visual outcome from cataract surgery.
