amplitude of accommodation and presbyopes
Apr 06, 2006 20:33:16 should amplitude of accommodation be measured when testing presbyope? if so, how because they are unable to read N5 without their reading Rx! |

Apr 07, 2006 20:37:59 By age 50 there is little useful accomodation left, so there is little point in measuring it. But I personally, always measure the depth of focus with the reading Rx. I do it monocularly as a check of binocular balancing, and binocularly to make sure I have given them a decent focal range and not too close. I do it on everyone. With early presbyopes - its different and worth doing - if only to show the patient the effect of reading glasses! -steve |
