Purpose : The use of femtosecond laser in refractive surgery has taken importance in Mexico.
The learning curve of the SMILE surgical technique is not known with accuracy to be a relatively new technique.
Determine the number of complications in this technique helps us to prevent and have a better manage post-surgical.

Methods : Prospective, descriptive and observational study.
We studied the complications intraoperative and postoperative, uncorrected visual acuity pre and post-surgery, <span style="line-height:20.8px">equivalent </span><span style="line-height:20.8px">sphere</span> and keratometry of patients undergoing refractive surgery with the surgical technique SMILE by femtosecond during January to October 2015, at the Foundation Hospital Nuestra Señora de la Luz. The platform for the surgery is VisuMax of Zeiss. The statistical analysis in Excel platform.

Results : Were studied 180 eyes of 90 patients undergoing refractive surgery with surgical technique "SMILE". Visual acuity corrected average pre surgical was not of 1.14 LogMAR (Snellen 20/276). The equivalent spherel pre surgical average - 4.2 diopters. The keratometry more flat and curved average was 42.9 and 44.6 diopters respectively. The average pachymetry was 559. 5±32 microns. Intra-operative complications were observed in 45/180 eyes. The main complication was difficult to extract the lenticule 19 (10.5%) cases, tear of incision 8 (4.4%) cases, epithelial abrasion 7 (3.8%) cases, loss of suction 5 (2.7%) cases, incomplete lenticule 3 (1.6%) cases, blackspot 2 (1.1%) cases and hemorrhage interface one (0.5%) case. All complications were resolved intraoperative.
Two patients with loss of suction the incision was performed manually, the 3 remaining rescheduled its refractive surgery 3 months later.
Postsurgical findings by biomicroscopy were 31 cases with detritus (17.22%) cases, superficial punctate keratopathy 25 (13.88%) cases,
epithelial defect 8 (4.44%) cases, haze 8 (4.44%), edema in interface 2 (1.11%), folds in incision 2 (1.11%), epithelial growth, interface with lenticule and diffuse lamellar keratitis one (. 55%)case for each of them.
The postsurgical spherical equivalent average per month was - 0.18 ±.31 diopters. The average final visual acuity was 0.02 LogMAR.

Conclusions : Intra-operative complications can be resolved at the time without affecting the fina lvisual acuity.
The SMILE surgical technique is secure with excellent results in the final visual acuity.

This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.
