Functional Outcomes After Implantation Of Two Toric Edof Iols With A Refractive Technology And Monofocal-Like Dysphotopsia Profile

The aim of this study was to compare two methods for intraoperative alignment and fixation of two toric enhanced depth of focus (EDOF) intraocular lenses (IOLs) in femtosecond laser-assisted phacoemulsification surgery (FLACS), the FEMTIS Comfort Toric FB-313 MF15T and the LENTIS Comfort Toric L-313 MF15T) and to evaluate postoperative functional outcomes. 

This prospective study included 55 eyes of 35 patients undergoing FLACS with implantation of the FEMTIS Comfort Toric (FB-313 MF15T) and the LENTIS Comfort Toric (L-313 MF15T). In 24 eyes of 16 patients, the capsulorhexis-fixed FB-313 MF15T was implanted, with toric IOL position aligned using LensAR femtosecond laser-assisted Intelliaxis Toric IOL marking. 32 eyes of 18 patients implanted with the L-313 MF15T received toric IOL alignment with the Callisto. Postoperative follow-up at 3 months included uncorrected (UDVA) and corrected distance visual acuity (CDVA), intermediate visual acuity (UIVA) at 80 cm and uncorrected near visual acuity (UNVA) at 40 cm, a binocular best-corrected defocus curve and evaluation of the rotational stability.

The mean binocular visual acuity in logMAR at 3-month follow-up was UDVA/CDVA (-0.03/-0.09), UIVA (0.07) and UNVA (0.20). 3 months postoperatively, the binocular, distance-corrected defocus curve showed a continuous visual acuity of 0.10 logMAR or better in the range of +0.50 to -1.0 diopters. At 3-month follow-up, both IOLs showed good rotation stability.

The initial results show good visual acuity and reduced photopic phenomena. In particular, patients reported little to no photopic phenomena during halo and glare simulations. Both IOLs show good rotational stability. The calculation of the IOL power for the lenses and the implantation behavior are straightforward.
