Purpose

The purpose of this study was to compare the clinical results of two state-of-art enhanced monofocal toric intraocular lenses (tIOLs). The TECNIS Eyhance Toric IOL (Model DIU) was compared with a standard toric monofocal IOL (TECNIS Toric, Model ZCT) in eyes undergoing cataract surgery.

Setting

Prospective interventional two-arm controlled single center study

Methods

A total of 68 eyes will be enrolled in this prospective, single center study. Until now, a tIOL was implanted in 25 eyes. Thereof, 15 eyes received the DIU-tIOL and 10 eyes the ZCT-tIOL. The mean age was 71.8±7.9 years. Preoperatively, the mean corneal astigmatism was 1.9±0.48 Diopters (D) (Range 1.26 - 2.87 D). Postoperative evaluations were performed after 1 day, 1 week, 1 month and 3 months.

Results

The refractive astigmatism was reduced from -1.85±0.72 D to -0.69±0.29 D (p<0.001), 1 month postoperative. The refractive astigmatism, after 1 month, measured -0.77 ± 0.33 D and -0.56±0.18 D in eyes with a DIU- and ZCT-tIOL (p=0.117). The uncorrected-distance visual acuity (VA) improved from 0.71±0.35 logMAR to 0.14±0.12 logMAR (p<0.001). The pre- and postoperative distance VA did not differ between the tIOLs (p-values>0.05). Yet, distance-corrected near VA was superior for the DIU- (0.09±0.04 logMAR), compared to the ZCT-tIOL (0.14 ± 0.05 logMAR, p = 0.024). One month after surgery, the difference between calculated and actual toric axis was 1.68±2.47°. The axis deviation was 1.36±2.01° and 2.13±3.09° for the DIU- and ZCT-tIOL (p=0.262).

Conclusions

In this interim analysis, the TECNIS Eyhance Toric IOL (Model DIU) demonstrated a good clinical outcome. In this regard, it can be seen as an appropriate toric intraocular lens for reducing corneal astigmatism. Moreover, compared to a state-of-art enhanced monofocal toric intraocular lens (TECNIS Toric, Model ZCT), the Eyhance Toric presented with an improved near-vision. No relevant complications occurred, neither intraoperatively nor postoperatively. However, a final conclusion can be drawn after the full completion of the study.
