The M-flex Multifocal IOL

Purpose: To evaluate the efficacy, safety, predictability and stability of the M-flex (Rayner) multifocal lens (IOL) in pseudophakic eyes after cataract and clear lens phacoemulsification in hyperopic and presbyopic patients. Initial results with the new Toric Multifocal Lens M-flex-T are also presented. Methods: A prospective, non-randomized, observational study in 61 eyes of 43 patients implanted with the M-flex IOL and operated by the same surgeon was performed. The mean follow-up was 12 months (range: 3–20 months). Data were collected with Datagraph-med 3.20-d. Changes in Uncorrected Visual Acuity (UCVA), Best Corrected Visual Acuity (BCVA), Refraction over time, refractive outcome, Defocus Equivalent, Uncorrected (UCNVA) and Best Corrected Near Vision (BCNVA) and Uncorrected Intermediate Vision at 65cm. (UIV) were recorded. Complications were noted. Results: UCVA was 0.8 or better in all the cases. The Defocus equivalent was 0.5 diopters or less in all the cases. At 1 year only 20% of patients reach J1 without addition glasses, 60% reach J3, 80% reach J5. The mean addition needed to reach J1 was 1.5 diopters. UIV at one year was 0.8 or better in 75% of cases. No one patient lost lines of vision. Complications were: monocular diplopia (1 case), significant halos (1 case), undercorrection (1 case), overcorrection (1 case). Conclusion: The M-flex IOL is safe, stable and predictable. Distance vision and intermediate vision are excellent. Near vision is acceptable as a „social reading lens“.
