Femtosecond laser-assisted capsulotomy marking produced lower residual astigmatism and better visual outcomes compared with conventional slit lamp-assisted manual marking during toric IOL implantation, according to a study.
Astigmatism correction with capsulotomy marking also delivered significantly higher axis alignment.
“To ensure high accuracy, it is important that toric IOLs have a precise axial position, which, in turn, depends on exact corneal marking. Several methods have been described to determine the best toric IOL position marking,” Qingzhong Chen, MD, and colleague
