To compare the corneal asphericity and higher\u2010order aberrations (HOAs) of femtosecond laser\u2010assisted in situ keratomileusis (FS\u2010LASIK) with Smart Pulse Technology (SPT) assisted transepithelial photorefractive keratectomy (Trans\u2010PRK) for myopia and myopic astigmatism correction.\n Methods<\/jats:italic>\n . This prospective study analyzed 88 eyes of 44 patients treated with FS\u2010LASIK and 64 eyes of 32 patients treated with Trans\u2010PRK. All eyes had low to moderate myopia with or without astigmatism (spherical equivalent (SE) <\u22126.00 diopters). The uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), SE, asphericity (\n Q<\/jats:italic>\n value) of the anterior corneal surface, index of surface variance (ISV), corneal higher\u2010order aberrations (HOAs), vertical coma (Z\n 3<\/jats:sub>\n \u22121<\/jats:sup>\n ), horizontal coma (Z\n 3<\/jats:sub>\n 1<\/jats:sup>\n ), and spherical aberration (\n Z<\/jats:italic>\n 4<\/jats:sub>\n 0<\/jats:sup>\n ) over a 6\u2009mm diameter central corneal zone diameter were evaluated preoperatively and 1, 3, and 6 months postoperatively.\n Results<\/jats:italic>\n . At 6 months, the UDVA and SE were \u22120.14\u2009\u00b1\u20090.06 and 0.33\u2009\u00b1\u20090.33D in FS\u2010LASIK and \u22120.15\u2009\u00b1\u20090.06 and 0.35\u2009\u00b1\u20090.37D in Trans\u2010PRK. There was no difference between the two groups in the postoperative UDVA and SE (\n P<\/jats:italic>\n > 0.05). After FS\u2010LASIK and Trans\u2010PRK, the\n Q<\/jats:italic>\n values in the 6, 7, 8, and 9\u2009mm zones and ISV of the anterior corneal surface significantly increased (\n P<\/jats:italic>\n < 0.001). At 1, 3, and 6 months after surgery, corneal HOA, Z\n 3<\/jats:sub>\n -1<\/jats:sup>\n ,\n Z<\/jats:italic>\n 3<\/jats:sub>\n 1<\/jats:sup>\n , and\n Z<\/jats:italic>\n 4<\/jats:sub>\n 0<\/jats:sup>\n in both groups were significantly increased compared with those before surgery, with statistically significant differences (\n P<\/jats:italic>\n < 0.001). At 1, 3, and 6\u2009months after surgery, the Z\n 3<\/jats:sub>\n \u22121<\/jats:sup>\n of the Trans\u2010PRK group was significantly lower than that of the FS\u2010LASIK group (\n P<\/jats:italic>\n < 0.001). \u0394HOA and \u0394Z\n 4<\/jats:sub>\n 0<\/jats:sup>\n were dramatically correlated with the \u0394Q value for both FS\u2010LASIK and Trans\u2010PRK procedures. The \u0394Q was significantly correlated with the preoperative SE, AD, and AD\/CCT after both two procedures (all\n P<\/jats:italic>\n < 0.001).\n Conclusions<\/jats:italic>\n . Both FS\u2010LASIK and Trans\u2010PRK caused the anterior corneal surface to become flatter, and the morphology of the corneal surface was irregular. Corneal HOAs were significantly increased after the two procedures. Trans\u2010PRK using SPT introduced less corneal vertical coma than FS\u2010LASIK. Corneal asphericity changes contributed to the corneal aberrations changes following FS\u2010LASIK and Trans\u2010PRK.\n <\/jats:p>","DOI":"10.1155\/2021\/3765046","type":"journal-article","created":{"date-parts":[[2021,12,6]],"date-time":"2021-12-06T13:50:08Z","timestamp":1638798608000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Corneal Asphericity and Higher\u2010Order Aberrations after FS\u2010LASIK and Trans\u2010PRK for Myopia"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2677-0332","authenticated-orcid":false,"given":"Yuan","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3041-3159","authenticated-orcid":false,"given":"Shuhan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4372-9171","authenticated-orcid":false,"given":"Guiqin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7646-2699","authenticated-orcid":false,"given":"Shaozhen","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9708-0355","authenticated-orcid":false,"given":"Ruihua","family":"Wei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3529-6131","authenticated-orcid":false,"given":"Yue","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,12,6]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2018.07.021"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.optom.2019.04.003"},{"key":"e_1_2_10_3_2","first-page":"681","article-title":"[Comparison of the anterior corneal asphericity after small incision lenticule extraction and femtosecond laser in situ keratomileusis]","volume":"52","author":"Su X.
