Abstract
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=<0.001). Internal
aberrometry showed higher values in the PC capsulotomy centration group
(p<0.01).
Conclusions : First Purkinje reflex (FPR) centered capsulotomy is
associated to a closer centration of the IOL to the visual axis.
