Purpose

To evaluate the visual outcome and astigmatic correction after trifocal intraocular lens (IOLs) implantation with the aid of modified femtosecond laser-assisted corneal relaxing incision (FS-CRIs) in Chinese cataract patients with low astigmatism.

Setting

Retrospective case series.

Methods

This retrospective study included cataract patients with regular corneal astigmatism ranging from 0.75 to 1.5D who underwent FS-CRIs combined with a trifocal IOL (PanOptix; Alcon) implantation in Beijing Aier-Intech Eye Hospital from November 2020 to September 2022. UDVA, UIVA, UNVA and refractive data were collected at 3 months. The pre- and post-operative high-order aberration (HOA) was collected. The change of astigmatism was analyzed by Alpins vector analysis.

Results

A total of 27 eyes of 23 patients were enrolled. The monocular UDVA (5m) at 3 months postoperatively was 0.04±0.09, a significantly improved compared to preoperatively 0.95±0.51(P＜.001). The corneal astigmatism was significantly reduced from 1.24±0.42 D to 0.49±0.34 D (P＜.001). The TIA was 1.25±0.43 D, the SIA was 1.16±0.52 D, and the DV was 0.5±0.34 D. The ME (difference between SIA and TIA) was -0.1±0.41 D, and the CI (ratio of SIA and TIA) was 0.93±0.36. The Angle of Error was 3.92° ± 16.90°. Total HOA was decreased from 0.89 ± 1.11 to 0.41 ± 0.55 (P = 0.184), and the corneal HOA was decreased from 0.17 ± 0.18 to 0.10 ± 0.10 (P = 0.129).

Conclusions

Trifocal IOL implantation following modified femtosecond laser-assisted corneal relaxing incision for Chinese cataract patients has demonstrated excellent visual efficacy and successfully decreased corneal astigmatism.
