The test is used when retinoscopy and the Jackson cross cylinder fail to reveal astigmatism or seem to give untrustworthy results. The patient is asked, with the eyes fogged by plus sphere to about 20/40 acuity, to identify the lines that appear blackest and sharpest. The minus cylinder axis is determined by multiplying the smaller ‘hour’ number by 30. Minus cylinders are added until the lines appear equally blurred. Clinicians performing this test with plus cylinder apparatus multiply the hour of the sharpest line by 30 and add 90 to find the degree of axis for addition of plus cylinder. Each two steps of plus cylinder correction must be accompanied by one step of minus sphere correction.★★★ Astigmatic Dial HD FEATURES★★★- Not entertainment app - professional medical tool!- HD iPad graphics- Correct distance instructions for test- Only useful professional tests- New FREE updates is upcoming!- Full iPad and iPad 2 support- Support for use with iPad VGA adapter with you monitor/TV/projector/etc.(c) Astigmatic Dial HD - Care about your eyes!
