PURPOSE: This study aims to compare the visual and refractive outcomes of two new aspheric intraocular lenses (IOLs), that is, Clareon (Model CNA0T0) and Tecnis Eyhance (Model ICB00), in patients undergoing phacoemulsification cataract surgery.
METHODS: A retrospective comparative analysis was conducted at a tertiary referral institute in South India. A total of 132 eyes (91 patients) were included, with 66 eyes implanted with Clareon IOL (group 1) and 66 eyes with Tecnis Eyhance IOL (group 2). Preoperative and postoperative data were collected from January 2022 to April 2024. Primary outcomes included uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), spherical equivalent, and refractive cylinder, measured at 3 weeks postoperatively. Statistical analysis was performed using an independent sample t -test and Statistical Package for the Social Sciences software, with P values <0.05 considered significant.
RESULTS: The mean log of minimum angle of resolution (logMAR) UDVA in group 1 was 0.14 (95% confidence interval [CI] [0.11, 0.17]) and in group 2 was 0.16 (95% CI [0.13, 0.19]) ( P value 0.16). The mean logMAR UNVA in group 1 was M = 0.55 (95% CI [0.53, 0.58]) and in group 2 was M = 0.5 (95% CI [0.48, 0.52]) ( P value 0.0006). The mean add required for group 1 was + 1.76 (95% CI [1.66, 1.86]) and for group 2 was M = 1.56 (95% CI [1.49, 1.62]) ( P value 0.0005).
CONCLUSION: At 3 weeks postoperatively, both IOLs provided excellent visual outcomes. Tecnis Eyhance IOL offered enhanced near-vision performance.
