Limbal relaxing incisions
A fixed depth diamond-guarded knife (Gemcision LRI 600 Microns Blade, Katalyst Surgical, chesterfield, MO, USA) will be used to create a paired circumferential corneal incision, following the limbal curvature, 1-1.5mm anterior to the limbus centered on the steep corneal meridian. The incision arc length will be ninety degree according to the Nichamin Age and Pachymetry Adjusted (NAPA) nomogram.
