Comparative evaluation of visual outcomes after bilateral implantation of an advanced or conventional monofocal intraocular lens

Abstract

Purpose: To assess the clinical outcomes and patient satisfaction of the Tecnis Eyhance, an advanced monofocal intraocular lens (IOL), compared to a conventional monofocal IOL. Design: Retrospective case-control study. Methods: This study included 120 eyes of 60 patients (30 patients in each group) who underwent bilateral cataract surgery either with the implantation of conventional monofocal IOLs (Tecnis PCB00), as a control group, or advanced monofocal IOLs (Tecnis Eyhance ICB00). Ophthalmological evaluation included the measurement of binocular corrected distance visual acuity (CDVA), monocular and binocular uncorrected distance visual acuity (UDVA), and uncorrected intermediate VA (UIVA). In addition the binocular defocus curve was analyzed. Furthermore a subjective questionnaire (Catquest-9SF) was used to assess vision and life quality. Results: The average binocular UDVA was 20/22 in the ICB00 group and 20/20 in the PCB00 model ( p = 0.62). The average monocular UIVA was 20/32 in the ICB00 group and 20/40 in the control group ( p < 0.001). We found the binocular UIVA, had a mean value of 20/30 in the ICB00, compared to 20/40 in the control group ( p < 0.001). The reported dysphotopsia was not significantly different between both groups ( p = 0.56). Regarding the life quality questionnaire, the ICB00 group showed less difficulty in activities requiring intermediate vision. Conclusion: Our results demonstrated a significant improvement in visual acuity for intermediate distance in the ICB00 group compared to the control group, without compromising distance visual acuity. We also found a greater capability for intermediate distance activities (namely for computer use and reading price tags) when comparing ICB00 patients with the control group.

Visual outcomes, spectacle independence, and patient satisfaction of pseudophakic mini-monovision using a new monofocal intraocular lens

“…In agreement with previous studies [24][25][26][27] , the present study found excellent distance and intermediate visual outcomes in both the Emmetropia and Mini-monovision groups, as all participants underwent bilateral implantation of the Eyhance IOL. There were no statistically significant differences in the refractive error or the binocular UDVA and UIVA between groups, and the absolute visual outcome values in eyes that were bilaterally targeted for emmetropia were similar to those of available results [24][25][26][27] . However, the binocular UNVA was significantly better in the Mini-monovision group than in the Emmetropia group.…”

Optical bench evaluation of the effect of pupil size in new generation monofocal intraocular lenses

“…Although no control lens was used on this study, the mean binocular DCIVA of the ISOPure IOL was 0.2 logMAR, which is between 0.1 and 0.05 logMAR lower than the DCIVA reported for the ICB00 in different studies [ 18 – 20 ] and in good agreement with pre-clinical simulations. In contrast, the distance VA was slightly better for the ISOPure (-0.09 ± 0.06 logMAR) compared to the results reported for the ICB00 (ranging between − 0.06 ± 0.01 logMAR [ 19 ] and 0.03 ± 0.09 logMAR [ 23 ]).…”
