All eyes were targeted for emmetropia. Refractive outcomes, higher-order aberrations (HOAs), and contrast sensitivity were analyzed preoperatively and postoperatively. Patient satisfaction was assessed using 2 questionnaires.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-results\">RESULTS:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Six months postoperatively, the mean manifest refraction spherical equivalent in all eyes was -0.09 D +\/- 0.31 (SD); of the 131 eyes, 116 (88.55%) had an uncorrected visual acuity of 20\/20 or better and 122 (93.13%) had an MRSE within +\/-0.50 D. The best spectacle-corrected visual acuity (BSCVA) increased by 2 or more lines in 21 (16.03%) of 131 eyes; no eye lost 2 lines or more of BSCVA. The total ocular HOA increased by 0.04 microm. Patients reported significantly fewer night driving and glare\/halo symptoms postoperatively than preoperatively.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-conclusions\">CONCLUSIONS:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use of a customized aspherical treatment zone in eyes with myopia and astigmatism was safe, effective, and predictable and reduced symptoms associated with night driving, glare, and halos.<\/p>\n\n\n\n<div  class=\" b-buttons\" >\n\t\t\t<a  class=\"b-buttons__button a-btn a-btn--has-icon-after icon-arrow-right\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/19006731\/\">\n\tLeer art\u00edculo<\/a>\n\t<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Paul J Dougherty, George Waring 3rd, Arturo Chayet, Jeffery Fischer, Barbara Fant, Harkaran S Bains.<\/p>\n","protected":false},"author":2,"featured_media":2804,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[141,57],"tags":[],"class_list":["post-1814","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-lasik-sin-cuchilla-o-prk","category-publicaciones-cientificas"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.3 (Yoast SEO v28.3) -
