Evaluation of Visual Outcomes and 3-Month Refractive Stability of a New Hydrophobic Acrylic Intraocular Lens.

Purpose: To determine the refractive stability of a new hydrophobic acrylic intraocular lens (IOL) when implanted bilaterally.

Methods: This was a prospective, evaluator masked, single surgeon study of 58 eyes of 29 patients. Patients were bilaterally implanted with the Clareon monofocal IOL (CNA0T0, Alcon Vision LLC). Refractive stability was evaluated between 1 and 3 months postoperatively. At 3 months postoperatively, data were also collected for binocular uncorrected and distance corrected visual acuities at distance (4 m) and intermediate (80 cm and 66 cm) and binocular defocus curve.

Results: Postoperative refraction was statistically equivalent between 1 and 3 months postoperatively (p < 0.001). Mean postoperative uncorrected distance visual acuity was -0.01 ± 0.10 logMAR, and mean corrected distance visual acuity was -0.04 ± 0.06 logMAR. Mean postoperative uncorrected intermediate visual acuity was 0.16 ± 0.13 logMAR and 0.24 ± 0.14 logMAR at 80 cm and 66 cm, respectively. With distance correction in place, mean visual acuity at 80cm and 60cm was 0.16 ± 0.13 logMAR and 0.23 ± 0.14 logMAR, respectively.

Conclusion: The Clareon monofocal IOL can provide stable refraction, excellent distance vision, and functional intermediate vision postoperatively.
