To compare the clinical outcomes between the group that had bilateral implantation of Femtis Mplus and the group that had bilateral implantation of RayOne intraocular lenses.
Retrospective chart review study
From September 1, 2020 to April 30, 2022, we retrospectively reviewed the charts of patients who underwent cataract surgery at BGN Jamsil Lotte Tower Eye Clinic, comparing 84 patients (168 eyes) who had bilateral implantation of Femtis Mplus and 290 patients (580 eyes) who had bilateral implantation of RayOne. All surgeries were performed by a single surgeon(J.W.K) using the FLACS method. Uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), and binocular distance-corrected defocus curves were measured between 6 and 10 weeks after cataract surgery. Additionally a questionnaire was conducted to assess the presence and bothersomeness of dysphotopsia, patient satisfaction with the surgery, and the need for glasses.
There was no significant difference in UDVA and UNVA among the two groups. Both monocular and binocular curve showed similar results. The RayOne group had better visual acuity than the Femtis group between -0.5 D and -2.0 D of defocus, and the Femtis group had better visual acuity than the RayOne group between -2.5 D and -3.0 D and -4.0 D of defocus. Questionnaire about the presence of visual symptoms, Femtis group showed statistically significant less glare, and halo than Rayone implanted group. But the bothersomeness about the visual symptoms especially the starburst was statistically significant in Femtis implanted group. Both groups had almost no spectacle dependence for near and far vision.
Femtis showed a good far and near vision with less need of glasses and very good patient satisfaction with the result and less incidence of dysphotopsia compared to RayOne IOL. It is thought that due to unique haptic design of Femtis, effective lens position and long term visual stability is ensured.
