Eighty eyes of 65 patients (40 eyes in each group) were enrolled. The mean age of the participants was 25.48 \u00b1 4.80 years and 62.5% were male. One-year changes in vision parameters, refraction, and Pentacam (Oculus Optikger\u00e4te GmbH, Wetzlar, Germany) indices were compared between the two groups using repeated measures analysis of variance.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p>One year after corneal cross-linking, uncorrected distance visual acuity in the total and partial group improved by 0.13 \u00b1 0.42 and 0.12 \u00b1 0.36 logMAR (<jats:italic>P<\/jats:italic>= .447), respectively, and corrected distance visual acuity improved by 0.00 \u00b1 0.19 and 0.13 \u00b1 0.20 logMAR (<jats:italic>P<\/jats:italic>= .001), respectively. Spherical equivalent decreased by 0.44 \u00b1 1.25 diopters (D) in the total group and 0.56 \u00b1 1.47 D in the partial group (<jats:italic>P<\/jats:italic>= .710). The decrease in maximum keratometry was 0.39 \u00b1 0.93 and 0.01 \u00b1 0.95 D in the total and partial group, respectively (<jats:italic>P<\/jats:italic>= .037), and the decrease in mean keratometry was 0.42 \u00b1 0.93 and 0.00 \u00b1 0.65 D (<jats:italic>P<\/jats:italic>= .015), respectively.

With the partial approach, there was slightly better corrected distance visual acuity improvement and central corneal thickness maintenance, but slightly better corneal flattening was achieved with the total removal. Long-term studies are needed to compare these two approaches in terms of stability of results and stopping the progression of keratoconus.<\/jats:p><jats:p><jats:bold>[<jats:italic>J Refract Surg<\/jats:italic>. 2015;31(2):110\u2013115.]<\/jats:bold><\/jats:p><\/jats:sec>","DOI":"10.3928\/1081597x-20150122-06","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T21:21:59Z","timestamp":1425417719000},"page":"110-115","source":"Crossref","is-referenced-by-count":19,"title":["Matched Comparison Study of Total and Partial Epithelium Removal in Corneal Cross-linking"],"prefix":"10.3928","volume":"31","author":[{"given":"Hassan","family":"Hashemi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Miraftab","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farhad","family":"Hafezi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soheila","family":"Asgari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2308","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9394(02)02220-1"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/ICO.0b013e3180334f78"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1167\/tvst.2.7.6"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2013.01.012"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2013.05.022"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081597X-20090901-02"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2012.03.038"},{"key":"e_1_3_2_9_2","first-page":"203","article-title":"Studies on the stabilization of the cornea in rabbits [article in German]","volume":"97","author":"Sporl E","year":"2000","unstructured":"Sporl E, Schreiber J, Hellmund K, Seiler T, Knuschke P.
