Lee), Department of Ophthalmology, University of Ulsan College of Medicine, Asan Medical Center, Seoul, South Korea (Moon, Park, H. Lee, Kim, Tchah), and the Department of Ophthalmology, Dankook University Hospital, Dankook University College of Medicine, Cheonan, South Korea (Chung).
Purpose:
To compare clinical outcomes of a new monofocal intraocular lens (IOL) with enhanced intermediate function and an extended depth-of-focus (EDoF) IOL.
Setting:
Asan Medical Center, Seoul, Korea.
Design:
Nonrandomized prospective comparative case series.
Methods:
Patients presenting for cataract surgery and meeting all inclusion and exclusion criteria were implanted with a new monofocal IOL with enhanced intermediate function (Tecnis Eyhance ICB00) or an EDoF IOL (Tecnis Symfony ZXR00) bilaterally. Uncorrected (UDVA), uncorrected intermediate (UIVA), uncorrected near (UNVA), and corrected distance visual acuity (CDVA), defocus curves, and contrast sensitivity were compared after 3 months. Patients were administered questionnaires regarding visual symptoms, spectacle independence, overall satisfaction, and lens recommendations.
Results:
24 patients (48 eyes) were enrolled in the Eyhance group and 20 patients (40 eyes) in the Symfony group. Monocular and binocular UDVA, UIVA, and CDVA were similar in the 2 groups. Monocular UNVA and spectacle independence for near distance were better in the Symfony group, whereas binocular UNVA did not differ significantly in the 2 groups. Contrast sensitivity, glare and halo, satisfaction, and recommendation rates were similar in the 2 groups. Although some dissatisfaction and severe glare and halo were reported in the Symfony group, none of these was reported in the Eyhance group.
Conclusions:
Bilateral implantation of the Eyhance ICB00 IOL provided comparable clinical performances as bilateral implantation of the Symfony ZXR00 IOL. Binocular UNVA was similar, although spectacle independence was higher in the Symfony group, but this was at the expense of more glare and halos.
