Incision meridian and the direction of surgically induced astigmatism after phacoemulsification: a single-surgeon vector analysis
Aims: To compare the keratometric surgically induced astigmatism (SIA) of two clear corneal incision strategies (120° oblique for monofocal cases, 180° temporal for trifocal cases) using Alpins double-angle vector analysis.Methods: In this retrospective single-surgeon study, 130 eyes of 106 patients undergoing phacoemu...
