PURPOSE: To evaluate and compare visual acuity outcomes of two different enhanced monofocal IOLs implanted in patients undergoing cataract surgery.

METHODS: This prospective study included patients who had undergone routine cataract extraction with the implantation of a novel monofocal plus IOL with enhanced intermediate optics (enVista Aspire, Bausch & Lomb) IOL or a monofocal plus (Tecnis Eyhance, Johnson & Johnson Vision). Outcomes measures included a comparison of the uncorrected and corrected visual acuity at distance (UDVA, CDVA), uncorrected intermediate visual acuity (UIVA, at 60 cm), and manifest refraction spherical equivalent (MRSE) between the two groups.

RESULTS: Preliminary analysis showed that the mean postoperative MRSE was -0.45 ± 0.30 D in the Aspire group (N = 16) and -0.04 ± 0.35 D in the Eyhance group (N = 13). The mean UDVA (0.05 ± 0.11 D vs 0.05 ± 0.12 logMAR) and CDVA (-0.02 ± 0.04 vs 0.00 ± 0.06 logMAR) were comparable between the Aspire and the Eyhance IOL groups. The Aspire and the Eyhance groups also showed comparable uncorrected visual acuity at intermediate, corresponding to 0.27 ± 0.11 logMAR and 0.26 ± 0.14 logMAR, respectively.

CONCLUSION: The Aspire and Eyhance IOL groups showed comparable visual acuity outcomes at distance and intermediate. Despite the more myopic manifest refraction spherical equivalent in the Aspire group, the uncorrected distance visual acuity outcomes were precise (as shown by the low standard deviation of the mean) and comparable to the Eyhance group.
