The LALs were implanted that would purposely result in myopic errors of up to -1.5 D (diopter). The LAL was treated with a spatial intensity profile delivered by a digital light delivery device to induce a targeted myopic refractive change. Once the desirable myopic correction was achieved, the LAL was treated again to lock-in the lens power.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-participants\">PARTICIPANTS:&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fourteen eyes of 14 patients were studied.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-methods\">METHODS:&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The manifest refraction, uncorrected visual acuity (UCVA), and best- or spectacle-corrected visual acuity (BCVA), were measured with follow up time of 1 to 9 months to determine the achieved refractive corrections and their stability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-main-outcome-measures\">MAIN OUTCOME MEASURES:&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">We measured UCVA and BCVA, achieved versus targeted refractive outcome, and refractive stability with follow up time of 1 to 9 months.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-results\">RESULTS:&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Of 14 eyes, 13 eyes (92.9%) achieved 0.25 D of the target refraction at 1 day post lock-in with 100% of the eyes achieving the targeted refractive adjustment within 0.5 D or better with up to 9 months postoperative follow-up. All eyes treated show no change in manifest spherical refraction &gt;0.25 D between 1 day post lock-in, and 3, 6, and 9 months postoperative visits. The data demonstrate the stability of the achieved refractive change after the adjustment and lock-in procedures. The mean rate of change was 0.006 D per month, which is 6 times more stable than that of laser corneal refractive procedures.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-conclusions\">CONCLUSIONS:&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Residual myopia errors up to -1.5 D were successfully corrected with precision and significant improvement in UCVA and without compromising BCVA using the LAL technology.<\/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\/19500852\/\">\n\tLeer art\u00edculo<\/a>\n\t<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Arturo Chayet, Chris Sandstedt, Shiao Chang, Paul Rhee, Barbara Tsuchiyama, Robert Grubbs, Dan Schwartz.<\/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":[143,144,57],"tags":[],"class_list":["post-1807","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cirugia-de-catarata","category-lente-ajustable-por-luz","category-publicaciones-cientificas"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.6 (Yoast SEO v28.6) -
