Purpose: We evaluated the 3-month, postoperative clinical outcomes of patients implanted with refractive, aspheric, bifocal, Lentis Comfort (LS313-MF15, Oculentis) intraocular lenses (IOLs).
Methods: Eighty-two eyes of 51 cataract patients underwent phacoemulsification and were implanted with Lentis Comfort IOLs.
The uncorrected distant visual acuity (UCDVA), the 80-cm uncorrected intermediate visual acuity (UCIVA), the 40-cm uncorrected near visual acuity (UCNVA), and refractive values were evaluated 1 and 3 months postoperatively. At the latter time, defocus curves were drawn, contrast sensitivity tested, and satisfaction surveyed.
Results: At the 3-month postoperative follow-up, the mean spherical equivalent was -0.12 ± 0.21 D; and the mean LogMAR UCDVA, 80-cm UCIVA, and 40-cm UCNVA were 0.02 ± 0.03, 0.13 ± 0.07, and 0.42 ± 0.10 respectively. The defocus curves revealed visual acuities in excess of 0.2 LogMAR at points between the distant and intermediate targets. The mean contrast sensitivity fell in the range of 90% of a normal population under both photopic and mesopic conditions. In terms of satisfaction, 71.8% of patients were satisfied or very satisfied, but about 20% reported dysphotopsia.
Conclusions: Implantation of the refractive, aspheric, bifocal, intraocular, Lentis Comfort in patients with cataracts improved both the distant and intermediate visual acuities by 3 months after surgery and the visual quality was comparable to that afforded by other IOLs both objectively and subjectively.
