Fort Worth, TX) or [II] Schwind Amaris 750S (Schwind eye-tech-solutions, Kleinostheim, Germany) platforms. The TIA and corresponding SIA results were analyzed using various techniques.<\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n \n Key findings were the negative SIA power (y\n 1<\/jats:sub>\n ) was significantly correlated with negative TIA power (x\n 1<\/jats:sub>\n ) and sine of the TIA axis (x\n 2<\/jats:sub>\n ) as follows: [A] I, y\n 1<\/jats:sub>\n = 0.829x\n 1<\/jats:sub>\n \u20130.403x\n 2<\/jats:sub>\n \u20130.325 (\n F<\/jats:italic>\n = 87.76,\n r<\/jats:italic>\n = 0.804,\n P<\/jats:italic>\n < .001, n = 127); II, y\n 1<\/jats:sub>\n = 0.891x\n 1<\/jats:sub>\n \u20130.037x\n 2<\/jats:sub>\n \u20130.192 (\n F<\/jats:italic>\n = 240.06,\n r<\/jats:italic>\n = 0.901,\n P<\/jats:italic>\n < .001, n = 119) and [B] I, y\n 1<\/jats:sub>\n = 1.063x\n 1<\/jats:sub>\n +0.233x\n 2<\/jats:sub>\n +0.411 (\n F<\/jats:italic>\n = 990.99,\n r<\/jats:italic>\n = 0.881,\n P<\/jats:italic>\n < .001, n = 61); II, y\n 1<\/jats:sub>\n = 1.029x\n 1<\/jats:sub>\n \u20130.115x\n 2<\/jats:sub>\n +0.322 (\n F<\/jats:italic>\n = 270.12,\n r<\/jats:italic>\n = 0.908,\n P<\/jats:italic>\n < 0.001, n = 111). The sine of negative SIA axis (y\n 2<\/jats:sub>\n ) was significantly correlated with negative TIA power (x\n 1<\/jats:sub>\n ) and TIA axis (x\n 2<\/jats:sub>\n ) as follows: [A] I, y\n 2<\/jats:sub>\n = 0.951x\n 2<\/jats:sub>\n \u20130.007x\n 1<\/jats:sub>\n +0.008 (\n F<\/jats:italic>\n = 446.58,\n r<\/jats:italic>\n = 0.950,\n P<\/jats:italic>\n < .001, n = 127); II, y\n 2<\/jats:sub>\n = 0.856x\n 2<\/jats:sub>\n +0.007x\n 1<\/jats:sub>\n +0.105 (\n F<\/jats:italic>\n = 277.18,\n r<\/jats:italic>\n = 0.912,\n P<\/jats:italic>\n < .001, n = 119) and [B] I, y\n 2<\/jats:sub>\n = 0.953x\n 2<\/jats:sub>\n +0.009x\n 1<\/jats:sub>\n +0.075 (\n F<\/jats:italic>\n = 362.6,\n r<\/jats:italic>\n = 0.963,\n P<\/jats:italic>\n < .001, n = 61); II, y\n 2<\/jats:sub>\n = 0.977x\n 2<\/jats:sub>\n \u20130.004x\n 1<\/jats:sub>\n +0.002 (\n F<\/jats:italic>\n = 2910.9,\n r<\/jats:italic>\n = 0.990,\n P<\/jats:italic>\n < .001, n = 111).\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS:<\/jats:title>\n The predicted SIA power was up to 12% less than expected in cases of \u22126.00 diopters cylinder treated for myopic astigmatism using the Allegretto platform. The mean predicted angle of error (the angle between the SIA and TIA axes) was less than 4\u00b0, increasing to 12\u00b0 for against-the-rule astigmatism. The Allegretto platform tended toward a clockwise axis rotational error, whereas the Amaris platform tended toward the opposite.<\/jats:p>\n \n \n [\n J Refract Surg.<\/jats:italic>\n 2017;33(2):104\u2013109.]\n <\/jats:bold>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.3928\/1081597x-20161102-01","type":"journal-article","created":{"date-parts":[[2017,2,13]],"date-time":"2017-02-13T18:11:49Z","timestamp":1487009509000},"page":"104-109","source":"Crossref","is-referenced-by-count":6,"title":["A Critical Evaluation of Refractive Outcomes Following LASIK for Moderate to High Astigmatism Using Two Excimer Laser Platforms"],"prefix":"10.3928","volume":"33","author":[{"given":"Sudi","family":"Patel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maja","family":"Bohac","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alma","family":"Biscevic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateja","family":"Koncarevic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marija","family":"Anticic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikica","family":"Gabric","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2308","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.85.9.1127"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1475-1313.2001.00596.x"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(13)80617-7"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-014-2776-2"},{"key":"e_1_3_3_6_2","first-page":"112","article-title":"A new and remarkably sensitive test for astigmatism","volume":"7","author":"Duncombe KO","year":"1933","unstructured":"Duncombe KO.
