Purpose: To determine whether LASIK flap complications are related to preoperative keratometry. Methods: The incidence and type of LASIK flap complications were recorded for 750 myopic eyes that underwent LASIK, and compared to preoperative keratometry, refraction, and corneal thickness. Results: The preoperative mean keratometry value was 43.90±1.55 (range 38.87-54.19). The mean preoperative spherical equivalent was -4.09±2.22 (range -0.50 to -11.38). The mean preoperative corneal thickness was 551.0±36.0um (range 459-655). Three flap complications were recorded. Two eyes with incomplete flaps had preoperative mean keratometry values of 44.63 (44.25/45.00) and 43.45 (43.90/43.00). One eye with a free cap had a preoperative mean keratometry of 44.06 (43.37/44.75). Conclusion: The data from this study did not support the observation that a higher incidence of LASIK flap complications is related to very high (≷48.0 D) or very low (< 40.0D) preoperative keratometry. Further studies are needed to elucidate the relationship between preoperative keratometry and LASIK flap complications.
