Change Of Wavefront Aberration In High Myopia Patients After Implantable Collamer Lens Implantation

PurposeTo observe the change of wavefront aberration in high myopia patients after implantable collamer lens implantationMethodsWavefront aberrations were evaluated in fifty eyes of 25 high myopia patients received ICL implantation by NIDEK Optical Path Differences (OPD) preoperatively and one-month postoperatively. The results were analysed by student t test.ResultsThe Zernike functional values of total aberration and internal total aberration in 6mm pupil size area of the postoperative eyes implanted ICL were found significantly statistical lower (p<0.05) than those of the preoperative eyes. The Zernike functional values of total high-order aberration, total spherical-like aberration, total coma-like aberration, total trefoil-like aberration and internal total coma-like aberration were found significantly statistical higher (p<0.05) than those of the preoperative eyes.ConclusionAlthough total aberrations could be decreased by implantable collamer lens implantation in high myopia eyes, high-order aberrations such as total spherical-like aberrations,total coma-like aberrations and total trefoil-like aberrations are increased in certain degree.
