Clinical Outcomes of New Monofocal Intraocular Lenses with Enhanced Intermediate Function Compared with Extended Depth of Focus Intraocular Lenses.
Abstract
PURPOSE\nTo compare clinical outcomes of a new monofocal intraocular lens (IOL) with enhanced intermediate function and an extended-depth-of-focus (EDOF) IOL.\n\n\nSETTING\nAsan Medical Center, Seoul, Korea.\n\n\nDESIGN\nNonrandomized prospective comparative case series.\n\n\nMETHODS\nPatients presenting for cataract surgery and meeting all inclusion and exclusion criteria were implanted with new monofocal IOLs with enhanced intermediate function (Tecnis Eyhance ICB00) or EDOF IOLs (Tecnis Symfony ZXR00) bilaterally. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), 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.\n\n\nRESULTS\nTwenty-four 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 two groups. Monocular UNVA and spectacle independence for near distance were better in the Symfony group, whereas binocular UNVA did not differ significantly in the two groups. Contrast sensitivity, glare and halo, satisfaction, and recommendation rates were similar in the two groups. Although some dissatisfaction and severe glare and halo were reported in the Symfony group, none of these was reported in the Eyhance group.\n\n\nCONCLUSIONS\nBilateral implantation of the new Eyhance ICB00 IOLs provided comparable clinical performances as bilateral implantation of Symfony ZXR00 IOLs. Binocular UNVA was similar, although spectacle independence was higher in the Symfony group, but this was at the expense of more glare and halos.
