PURPOSE: To compare intermediate visual outcomes in patients previously implanted with bilateral Clareon monofocal IOLs versus bilateral Eyhance IOLs.
METHODS: This was a non-interventional, single-center, examiner-masked, comparative study. Participants were cataract patients presenting at least 3 months after uncomplicated, bilateral implantation of either Clareon or Eyhance non-toric and toric IOLs. Outcomes measures included binocular distance-corrected intermediate visual acuity (DCIVA), binocular corrected distance visual acuity (CDVA), binocular best-corrected defocus curve, postoperative mean residual spherical equivalent (MRSE), and residual astigmatism.
RESULTS: A total of 620 eyes of 310 subjects (155 subjects per group) were evaluated. The mean difference in DCIVA was 0.05 logMAR between the Eyhance and Clareon IOLs which was significant (p < 0.01), but within the 0.1 logMAR non-inferiority margin. Mean CDVA of the Clareon group was 0.01 ± 0.03 logMAR compared to 0.02 ± 0.03 logMAR of the Eyhance Group (p > 0.05). Defocus curves from +1.0 D to -3.0 D were not clinically nor statistically different between the Clareon and Eyhance groups (p > 0.05).
CONCLUSION: The results of this study show that bilateral implantation of Clareon monofocal IOLs and Eyhance monofocal IOLs lead to similar distance and intermediate visual outcomes.
