  • Abstract
  • Look Inside

Photographic phacometry in horizontal and vertical meridian was performed on 37 Astig-matic eyes, (10 males, 27 females from 5 to 30 years of age), refractive error of witch were distributed from +8.0D to -20D. Degree of Astigmatism was obtained for each optical component by reducing vertical values from horizontal ones. Mean of lenticular Astigma-tism was 0.5D against rule.

Other astigmatic components were as fol-lows. ( ); mean value

1. d (1/P'); spectacler Astigma. (refractive error on cornea, by skiascopy), (-1.37D with rule)

2. dDC; corneal Astigma.(+1.82D with rule)

3. dDL; lenticular Astigma.(-0.5D) against rule)
