Design outcomes

Primary

Measure	Time frame
"1- Surgically Induced Astigmatism (SIA): - Quantified by the difference in keratometric values pre- and postoperatively. - Compared across the three incision types (straight, frown, chevron). 2- Postoperative Visual Acuity: - Uncorrected Visual Acuity (UCVA) and Best-Corrected Visual Acuity (BCVA) at 30 days post-surgery. - Used to assess functional visual recovery."	—
