Potential Acuity Assessment: A Comparison Of The Mentor Potential Acuity Meter And The IRAS Portable Interferometer.

With the advancement of surgical techniques and the public's increasing demand for clear vision, we are beginning to see a remarkable increase in the number of cataract extractions with intraocular lens implants. In addition, the cataract patient is more knowledgeable about the techniques and interested in the possible improvement after surgery. Modern instrumentation now allows us to accurately predict the prognosis for good visual acuity after surgery. Two of these instruments will be discussed in detail and compared to determine which one provides a better prognosis when both are used on the same eye. Wwe chose the Mentor PAM and IRAS laser
interferometer for a comparison study to determine which instrument predicts
a better potential acuity on a given eye and to find which instrument is
more practical to incorporate into the average optometrist's practice.
