ABSTRACT

Purpose: To report the complications that arose from the use of Laser in situ keratomileusis (LASIK) in the treatment of high degree myopia.
Method: A retrospective, descriptive, observational study was carried out in the Ophthalmology Center of the Hospital San José Tec de Monterrey-Escuela de Medicina Tec de Monterrey during the period of January 2004- January 2006. 4800 eyes were included with a minimal follow-up period of 12 months. Inclusion criteria included age greater than 18 years, stable refraction for at least a year and a complete pre-surgical evaluation (complete corneal exam, topography, ultrasound pachymetry). Exclusion criteria included patient with corneal pathology, uveitis, glaucoma, maculopathy and retinopathy. Surgeries were performed by 30 ophthalmologists. Transoperative and postoperative complications were registered.
Results: Complications were reported in 0.83% (40 eyes). Transoperative complications were the following: incision interruption in 0.08% (4 eyes), defective blades in 0.06% (3 eyes), loss of suction in 0.06% (3 eyes), epithelial cell loss in 0.39% (19 eyes), and buttonhole flap in 0.02% (1 eye). Postoperative complications included flap striae in 0.02% (1 eye), epithelial ingrowths in 0.02% (1 eye), and flap misplacement in 0.125% (6 eyes).
Conclusion: LASIK is a safe procedure for the treatment of refraction errors. In the present study none of the reported complications had a long term deleterious effect on visual acuity. Complication incidence reported was similar to previous reports, 0.83%
