Dispensing for Astigmatism: Case Study

Turners Optometrists presents a case study of a difficult 20D astigmatism correction handled by dispensing optician Arran Taylor and Norville Optical

Every now and then an unusual prescription crops up and increasingly it is difficult to get the 'one-off special' lens made in an acceptable form.

This occurred in late 2006 at Turners Optometrists in Bridgwater, Somerset, when a longstanding patient turned up for her next examination.

I had been seeing the patient for a couple of decades, and her most recent prescription turned out to be:

R +15.00 / -20.00 x 80

L +12.00 / -16.00 x 105
