Intermediate Visual Acuity After Bilateral Implantation Of Advanced Monofocal Tecnis Eyhance Intraocular Lens

Due to changing lifestyle habits, intermediate vision is becoming of paramount importance for many patients. Until recently functional uncorrected intermediate vision was obtainable either with EDOF of trifocal intraocular lenses (IOLs). However, those IOLs also have a more pronounced dysphotopsia profile and some contrast sensitivity issues compared to standard monofocal IOLs. Johnson and Johnson Tecnis Eyhance (ICB00) IOL is a new advanced monofocal IOL designed to improve intermediate vision but simultaneosly keeping dysphotopsia profile and contrast sensitivity comparable to standard monofocal IOLs. The purpose of this paper is to present results after bilateral Tecnih Eyhance IOL implantation.

Postoperative data of 30 patients (60 eyes) that underwent bilateral cataract surgery or refractive lens exchange with implantation of a Tecnis Eyhance IOL were analyzed in this retrospective observational study. Depending on preoperative corneal astigmatism, temporal or superior 2.4 to 2.75 mm incisions were used. In 23 patients bilateral emetropia was planned, and in 7 patients micro/mini monovision of -0.50 to -1.0 diopters was planned. One month post op, we analyzed monocular corrected distance visual acuity (CDVA), binocular uncorrected intermediate visual acuity (UIVA) at 65 cm and positive dysphotopsia complaints. Binocular defocus curves and photopic contrast sensitivity charts for selected patients were also analyzed.

Mean monocular CDVA was 0.02 logMAR (range 0.07 to -0.1) Mean binocular UIVA was 0.11 logMAR (range 0.2 to 0.05). 29 of 30 patients stated that they could use desktop/laptop computer without glasses. Seven patients that were planned for micro/mini monovision postoperativley had spherical equivalent from -0.50 to -1.25 diopters and had photopic uncorrected near visual acuity at 40 cm of at least 0.18 logMAR. No patient complained of positive dysphotopsias like glare, halos or starbursts. Defocus curves of selected patients targeted for bilateral emetropia showed functional visual acuity all up to -2.0 diopters of defocus. Binocular photopic contrast sensitivity values were comparable to values after implantation of standard monofocal IOLs.

In our experience, bilateral Tecnis Eyhance advanced monofocal IOL implantation resulted in good functional binocular uncorrected visual acuity and spectacle independance at intermediate distance of 65 cm for almost all of our patients, while preserving good distance visual acuity, photopic contrast sensitivity and favorable dysphotopsia profile comparable to standard monofocal IOLs.
