Abstract Details


At the moment, the Smile technology more often uses in high to medium myopia, since in mild myopia the very thin lenticule is formed and problems with removing it often occur. Purpose - Modification of Smile technology and evaluation of clinical efficacy in mild myopia.


Irkutsk Branch of S. Fyodorov Eye Microsurgery Federal State Institution, Irkutsk, Russia


To prevent intraoperative complications and getting a good refractive effect the corneal incision was increased from 2 mm to 3 mm, facilitating lenticular extraction. Instead of the standard minimum lenticular thickness of 15 microns, we make individual recalculation of lenticular thickness up to 20 microns, which allows more clearly and integrally separating it and does not adversely affect the functional outcome. The study included 68 patients (135 eyes), operated by Smile method. UVA before surgery averaged 0,14 +/- 0,02, with correction 0,94 +/- 0,04, spherical component was -2,1 +/- 0,51, cylindrical component was -0,47 +/- 0,08.


During surgery and postoperatively complications were not observed. In all patients the next day after surgery, monocular and binocular uncorrected visual acuity was significantly higher (0,82 +/- 0,11) and (0,91 +/- 0,1), but maximum values of visual acuity were achieved by the month (0, 95 +/- 0,03) and (0,97 +/- 0,07). Spherical component was -0,01 +/- 0,01 the first day after surgery, diopter cylindrical one -0,25 +/- 0,02 D.


Analysis of the results of a study with using the proposed recommendations, allows suggesting femtosecond SMILE technology effective and safe method for correcting refractive errors in patients with mild myopia.
