Abstract
PURPOSE: To examine the 6-month outcomes of visual performance and positional stability of a capsule-fixated intraocular lens (IOL), FEMTIS Comfort MF15, extended depth-focus (EDOF) version, after cataract surgery performed using femtosecond laser-assisted cataract surgery capsulotomy. SETTING: Vision Eye Institute, Sydney, Australia. DESIGN: Prospective open-label postregistration data collection. METHODS: Three-month and 6-month outcomes were measured including visual function, stability of IOL position, and quantitative measurement of glare and halo. Subjective patient satisfaction and spectacle independence rates were documented with a subjective questionnaire. A computer simulator was used to quantify the incidence and severity of unwanted visual phenomena allowing comparison with other EDOF and multifocal IOLs. RESULTS: Forty-four eyes of 25 patients were included in the study. There were 19 bilateral cases. The median shift in IOL position over 6 months (from surgery to 6 months) was 0.095 ± 0.09 mm. There was a marked improvement in uncorrected and corrected distance visual acuity from the preoperative to the 6-month mark. Patient satisfaction and spectacle independence levels were high. There was no IOL enclevation, negative dysphotopsia, decentration, or capsular phimosis. CONCLUSIONS: To the authors' knowledge, this is the first study to report outcomes after insertion of the FEMTIS capsulorhexis-fixated EDOF IOL. This IOL offers excellent refractive predictability, functional range of vision, and minimal unwanted visual phenomena. The attachment to the anterior capsulorhexis is shown to be stable over time with no significant shift in the position or capsular phimosis. There was high patient satisfaction with spectacle independence.
