Ten-year Follow-up of Laer In itu Keratomileui for High Myopia Original Reearch Article

Purpoe To evaluate the long-term outcome of laer in itu keratomileui (LAIK) for high myopia. Deign A long-term (10 year) follow-up retropective interventional cae erie tudy. Method The tudy included 196 myopic eye of 118 patient with a mean preoperative pherical equivalent of −13.95 ± 2.79 diopter (D) treated with myopic LAIK at the Intituto Oftalmológico de Alicante, pain uing the VIX 20/20 excimer laer (VIX Inc, anta Monica, California, UA) and the Automated Corneal haper microkeratome (Chiron Viion, Irvine, California, UA). All patient were evaluated three month, one year, two year, five year, and 10 year potoperatively. The main outcome meaure were refractive predictability and tability, mean corneal keratometry, topographical cylinder, afety, efficacy, tability of viual acuity, and potoperative complication. Reult At 10 year, 82 (42%) of 196 eye were within ±1.00 D and 119 (61%) were within ±2.00 D. Fifty-four (27.5%) eye underwent retreatment attributable to under correction and/or regreion. The myopic regreion decreae with time in eye that did not undergo retreatment with a mean rate of −0.25 ± 0.18 D per year. Eleven eye (5%) lot more than 2 line of bet pectacle-corrected viual acuity (BCVA) and 78 eye (40%) howed a potoperatively uncorrected viual acuity of 20/40 or better. Two eye (1%) with more than 15 D myopic correction developed corneal ectaia. Concluion LAIK for myopia over −10 D i a afe procedure with myopic regreion that low down with time and a high rate of BCVA increae in the long-term.
