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

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

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.

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.

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