Visual potential: Pam or potential acuity meter is a device used to test someones visual potential through cataracts. It is not an absolute reading but a good estimation of what someones vision may be after cataract surgery.

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.

Testing retina: A small beam of light with an eye chart is directed into the eye through or around opacities in the lens and cornea. And projects the image on the retina. Your readings indicate the potential visual acuity. The device is called a pam (potential acuity meter).

PAM Potential Acuity: PAM (Potential Acuity Meter) can determine if it is just the cataract affecting general vision or something else (ie, macular membrane/ ERM. Small letters are projected with light (no pain) onto macula to see what best vision might be. Frustration is in fact: still no guarantee. More info: eyedoc2020@blogspot.com
