ARCUATE KERATOTOMY VERSUS TORIC INTRAOCULAR LENS IMPLANTATION IN FEMTOSECOND LASER ASSISTED CATARACT SURGERY FOR LOW TO MODERATE CORNEAL ASTIGMATISM: A PROSPECTIVE RANDOMISED CONTROLLED TRIAL

Both femtosecond laser arcuate keratotomy (FSAK) and toric intraocular lenses (TIOLs) are established techniques to correct corneal astigmatism during cataract surgery. With the advent of the ALLY Adaptive Cataract Treatment System, the precision and integration of FSAK have improved. This randomized controlled trial evaluates FSAK versus TIOLs for astigmatism correction. It is a  prospective, assessor-masked, randomized controlled trial at a tertiary care centre over 06 months. Patients with regular corneal astigmatism (1.0–2.0 D) and visually significant cataract will be randomized to either FSAK and monofocal IOL using ALLY, or  TIOL implantation using ALLY. Primary endpoint is residual refractive cylinder at 3 months. Secondary outcomes are uncorrected and bestcorrected distance visual acuity, vector analysis, rotational stability (TIOL), patient satisfaction, and adverse events.This trial will clarify whether ALLY assisted FSAK can achieve refractive outcomes comparable to TIOL implantation with potential workflow advantages.
