ABSTRACT
PURPOSE:
To evaluate rotational stability of Toric Implantable Collamer Lens (ICL) implantation to correct myopic astigmatism.METHODS:
We estimated the degree of Toric ICL rotation together with change in visual acuity and astigmatism in 118 eyes of 66 patients who underwent Toric ICL implantation and had a long-term mean follow-up period of 37 months.RESULTS:
After Toric ICL implantation, 107 (91%) out of 118 eyes showed uncorrected visual acuity of 0.8 or better. The mean postoperative astigmatism decreased to -0.64 +/- 0.61 D from a mean preoperative astigmatism of -2.96 +/- 1.13 D. The mean axis change of Toric ICL was 2.4 +/- 3.8 degrees during follow-up period. Two (1.7%) out of 118 eyes showed the axis change of more than 10 degrees. These two eyes had a decrease in visual acuity, rotational axis change of 18 degrees and 30 degrees, respectively, and increases in astigmatism of 1.50 D and 1.00 D, respectively. The remaining 116 eyes (98.3%) showed excellent rotational stability without visual acuity decreasing Toric ICL rotation during the follow-up period.CONCLUSIONS:
Toric ICL implantation to correct high myopia with astigmatism rarely has axis rotation and maintains excellent rotational stability for long-term follow-up.
