Pupil versus 1st Purkinje capsulotomy centration with femtosecond laser: Long term outcomes with a sinusoidal trifocal lens

Purpose To assess the role of femtosecond laser‐assisted capsulotomy centration in the long‐term intraocular positioning of a multifocal intraocular lens. Design Prospective comparative study. Methods A total of 60 eyes of 30 patients underwent femtosecond laser‐assisted Refractive Lens Exchange (RL...

Description
Summary:Purpose To assess the role of femtosecond laser‐assisted capsulotomy centration in the long‐term intraocular positioning of a multifocal intraocular lens. Design Prospective comparative study. Methods A total of 60 eyes of 30 patients underwent femtosecond laser‐assisted Refractive Lens Exchange (RLE). For every patient, capsulotomy centration was randomly performed according to pupil centre (PC) in one eye and first Purkinje reflex (FPR) in the other. The intraocular lens (IOL) positioning, visual acuities, spherical equivalent, internal aberrometry and quality of vision were assessed and compared at 3 years' follow‐up between groups (PC and FPR). Results Intraocular lens positioning showed a statistically significant difference between groups, with a closer centration to the visual axis in the FPR patients (p
