All patients first underwent femtosecond laser\u2013enabled placement of ICRS (Keraring, Mediphacos) (first step). Same-day topography-guided PRK and CXL (second step) were subsequently performed in all patients after the refraction was stable (average 6 months [range: 3 to 11 months]).<\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n \n Thirteen eyes from 13 patients were included in the study. Based on values before the first step and 6 months after the second step, significant improvements were noted in uncorrected distance visual acuity (0.7\u00b10.32 logMAR vs 0.08\u00b10.08 logMAR), corrected distance visual acuity (CDVA) (0.16\u00b10.19 logMAR vs 0.02\u00b10.04 log-MAR), sphere (\u22123.65\u00b13.08 diopters [D] vs 0.06\u00b11.6 D), astigmatism (\u22123.31\u00b11.5 D vs \u22120.98\u00b10.75 D), average K (47.28\u00b11.99 D vs 41.42\u00b13.22 D), and coma (2.36\u00b11.23\n \u03bc<\/jats:italic>\n m vs 1.47\u00b10.68\n \u03bc<\/jats:italic>\n m) (\n P<\/jats:italic>\n <.05).
