| description | AIM: To investigate the refractive outcomes and changes of corneal astigmatism and higher-order aberrations(HOAs)after Toric implantable Collamer lens implantation(Toric ICL).METHODS: Prospective nonrandomized clinical trial studies. This study included 102 eyes of 57 patients underwent Toric ICL for myopic astigmatism correction. Uncorrected visual acuity(UCVA), manifest refraction, best spectacle-corrected visual acuity(BSCVA), manifest refractive cylinder, the corneal astigmatism and HOAs were measured preoperatively and up to 6mo after surgery. The vectors were measured using corneal topography, the Pentacam HR system and Wavefront analyzer.RESULTS:Postoperative, the percentage of eyes had a spherical equivalent refraction within -1.00 D were 93.80%. The percentage of eyes within -0.50 D of emmetropia were 85.30%. The percentage of eyes which postoperative UCVA ≥20/25 was 66.30% and the percentage of eyes which postoperative UCVA ≥20/20 was 65.50%. The corneal astigmatism and aberrations preoperatively showed no statistical significance compared with postoperative. The total eyes aberrations and coma resulted in slight changes and had no statistically significant.CONCLUSION:The corneal incision of Toric ICL implantation caused no changes in astigmatism and higher-order wavefront aberrations of cornea. |
