Comparison of toric intraocular lens alignment between femtosecond laser–assisted capsular marking and manual corneal marking
Journal of Refractive Surgery Aug 14, 2020
Cao D, et al. - The researcher conducted this prospective study for comparing toric intraocular lens (IOL) alignment between femtosecond laser-assisted capsular marking and manual corneal marking. The sample consisted of 72 consecutive patients (72 eyes) with cataract and anterior corneal astigmatism of 1.00 diopter (D) or greater undergoing femtosecond laser-assisted cataract surgery with implantation of a toric IOL. All capsular markers were retained for at least 3 months in the femtosecond laser capsular marking group. It was noted that 22.2% of the corneal markers vanished within 1 month and all markers disappeared within 3 months in the manual marking group. In the femtosecond laser-assisted capsular marking group, IOL misalignment was significantly lower than in the manual corneal marking group. The long-term preservation of the capsular marker is also useful in assessing the rotation of the toric IOL.
