Intraoperative Complications of Laser in Situ Keratomileusis in Yazd

Purpose: Laser in situ keratomileusis (LASIK) is a popular method for correcting refractive errors. We survived the incidence and types of LASIK intraoperative flap complications in Yazd refractive surgery center.

Methods: Medical records of all patients who underwent Laser in situ keratomileusis were reviewed retrospectively. Flap related complications including buttonhole, incomplete, irregular, free and thin flaps were studied. Finally data was analyzed by SPSS-16 based on aims.

Results: In 1000 eyes (from 395 males and 605 females), 16 cases (1.6%) were affected by flap related complications. the most frequent complications were incomplete flap (56.3%), irregular flap (31.3%) and buttonhole (12.5%), respectively. The age group of 40-45 years old and patients with 580-590µ corneal thickness affected from the complications frequently. Also, statistically significant difference was seen between anterior and posterior corneal radius of curvature and incidence of complications (P. Value=0.0001).

Conclusions: Incomplete flap is the most frequent flap related complication in Yazd; we conclude that with higher corneal radius of curvature incidence of this complication is higher.
