Abstract Details


To compare the efficacy, predictability and quality of vision after small incision lenticule extraction (SMILE) and laser insitu keratomileusis (LASIK) for myopia and myopic astigmatism.


Centre for Sight, Banjara Hills, Hyderabad - India, a private tertiary care super specialty eye hospital.


A retrospective comparative analysis of outcomes of SMILE (Group I) and LASIK (Group II) was done. Group. Group I consisted of 152 eyes of 76 patients with a mean spherical equivalent of -3.89 +/- 1.89 diopters and group II consisted of 204 eyes of 102 patients with a mean spherical equivalent of -3.26 +/- 1.25 diopters. Subjective visual complaints, refraction, visual acuity, mesopic visual acuity, low contrast visual acuity, corneal Q value, and higher order aberrations were measured preop and post operatively at 1 week, 1 month, 3 months and 6 months.


141 (92.76%) eyes in Gr. I and 185 (90.68%) eyes in Gr. II had a visual acuity of 20/20 at one month (p>0.5). 144 (94.7%) eyes in Gr.1 and 186 (91.1%) in Gr.II had a mesopic vision of 6/6 or better (p<.05). 138 (90.7%) eyes in Gr. I and 182 (89.2%) eyes in Gr. II had a low contrast acuity of 0.1 or better (p>0.5). 11 (14.4%) patients in Gr. I and 20 (19.6%) patients in Gr. II complained of glare at night (p<0.5). Gr. I (0.298+/-0.102um) had fewer aberrations(HOA) than Gr. II (0.410+/- 0.152um) (p<0.1).


SMILE and LASIK are both safe and effective procedures for correction of myopia and astigmatism. However, SMILE induces lesser degree of higher order aberrations and offers a marginally better quality of vision as compared to LASIK.
