Wave-front aberration changes in high myopia patients after implantable collamer lens implantation

AIM: To observe the changes of wave-front aberration in high myopia patients after implantable collamer lens (ICL) implantation. METHODS: Wave-front aberrations were evaluated by NIDEK Optical path differences (OPD) in 50 eyes of 25 high myopia patients who received ICL implantation preoperatively and 1 month postoperatively. The results were analyzed by Student's t test. RESULTS: The Zernike functional values of total aberration and internal total aberration in 6mm pupil size area of the postoperative eyes implanted with 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. The Zernike functional values of cornea aberration were not found significantly statistical changes compared with those of the preoperative eyes. CONCLUSION: Although 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.
