摘要

Purpose

To evaluate changes in intraocular, corneal, and whole-eye higher-order aberrations (HOAs) after EVO intraocular collamer lens (ICL) implantation.

Methods

In this retrospective study, we enrolled 53 eyes of 53 patients and measured their refractive parameters and intraocular, corneal, and whole-eye HOAs using OPD scanning preoperatively and 1 month, and 3 years postoperatively. All statistical analyses were performed using SPSS software.

Results

The safety index was 1.31 ± 0.15, and the efficacy index was 1.02 ± 0.24 3 years postoperatively. The best linear fit curve of the attempted versus achieved correction was y = 0.96x + 0.08 at 3 years postoperatively. The mean spherical equivalent decreased from − 8.53 ± 2.49 D preoperatively to -0.09 ± 0.25 D and − 0.34 ± 0.41 D at 1 month and 3 years postoperatively, respectively (P < 0.05). The whole-eye trefoil and total HOAs, intraocular trefoil, corneal trefoil increased significantly at 1 month (P < 0.05) but did not change significantly at 3 years (P > 0.05) postoperatively compared to the preoperative value. The intraocular spherical aberration and total HOAs increased significantly at 1 month and 3 years postoperatively (P < 0.05). The whole-eye coma or spherical aberration, intraocular coma, corneal coma or spherical aberration or total HOAs did not differ from those observed at 1 month and 3 years postoperatively (P > 0.05).

Conclusions

Long-term EVO-ICL implantation is safe, effective, predictable, and stable. The intraocular and corneal trefoils increased significantly in the early postoperative period but can be recovered to the preoperative level in the long term. The intraocular spherical aberration increases slightly in the long term postoperatively, but the whole-eye spherical aberration does not change significantly.
