a WTR corneal astigmatism group
Corneal astigmatism was defined as WTR when the steep corneal cylinder axis was within 30 degrees of the horizontal axis.
an ATR corneal astigmatism group
Corneal astigmatism was defined as ATR when the cylinder axis was within 30 degrees of the vertical axis.
- Difference of toric intraocular lens power between three toric calculators [ Time Frame: Immediately after measurement ]Comparison of the toric intraocular lens power calculated from Acrysof and TECNIS toric calculators using keratometric values measured by autokeratometry or IOLMaster PCI and that from iTrace toric calculator with keratometric value measurement using iTrace ray tracing wavefront aberrometry and iTrace simulated keratometry.
