Abstract

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.

新型疏水丙烯酸人工晶状体的视力及3个月屈光稳定性评价。

目的:观察双侧植入新型疏水丙烯酸人工晶状体的屈光稳定性。方法:这是一项前瞻性、评估者蒙面、单外科医生研究，涉及29例患者58只眼。患者双侧植入Clareon单焦点人工晶状体(CNA0T0, Alcon Vision LLC)。术后1 - 3个月评估屈光稳定性。术后3个月，收集双眼未矫正视力和距离矫正视力(4 m)、中间(80 cm和66 cm)和双眼离焦曲线的数据。结果:术后1 ~ 3个月屈光度差异有统计学意义(p < 0.001)。术后未矫正距离平均视力为-0.01±0.10 logMAR，矫正距离平均视力为-0.04±0.06 logMAR。在80 cm和66 cm处，术后未矫正的平均中间视力分别为0.16±0.13 logMAR和0.24±0.14 logMAR。距离校正到位后，80cm和60cm处的平均视力分别为0.16±0.13 logMAR和0.23±0.14 logMAR。结论:Clareon单焦点人工晶状体术后屈光稳定，远视力良好，中间视力功能良好。
