Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Femtosecond laser arcuate keratotomy
femtosecond laser arcuate keratotomy will be designed using Donnenfeld nomogram.
Femtosecond laser arcuate keratotomy
The patient will receive femtosecond laser arcuate keratotomy and femtosecond laser-assisted cataract surgery with implantation of a monofocal intraocular lens in one eye.
Toric intraocular lens implantation
The Toric IOL power and alignment axis were calculated using the online calculator available at https://www.tecnistoriccalc.com
Toric intraocular lens implantation
The patient will receive femtosecond laser-assisted cataract surgery with implantation of a Toric monofocal intraocular lens in the contralateral eye.
