Background: Flap creation is the most critical step of laser in situ keratomileusis (LASIK). Also, the introduction of the femtosecond laser with its uniform flaps enhancing the accuracy of LASIK has decreased the risk of flap related complications like buttonholes and incomplete flaps. We proposed femtosecond laser-assisted LASIK in the presence of superficial corneal opacities.
Case Presentation: We reported a case of a 24-year-old female patient presented to the Cornea clinic of the Sohag Center for LASIK and Corneal Surgeries, Sohag, Egypt, complaining of bilateral decreased vision due to bilateral refractive error. The uncorrected distance visual acuity (UDVA) in the right eye (OD) was 0.01 with corrected distance visual acuity (CDVA) to 0.7 in decimal by a refraction of -3.50Ds/ –3.00Dc x 172°, while the UDVA in the left eye (OS) was 0.01 with CDVA to 0.6 in decimal by a refraction of -1.75 Ds/-6.00Dc x164°. Slit-lamp examination of the anterior segment showed bilateral superior vascularized corneal scars. Corneal tomographic imaging by Scheimpflug based tomography device (Oculus Inc., Wetzlar, Germany) revealed a symmetrical bow tie with very steep cornea with no other ectatic changes. The patient underwent bilateral femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) using an excimer laser. No intraoperative complications occurred. She was followed up for two years with serial corneal topographies with stable post LASIK results and visual outcomes.
Conclusions: FS-LASIK in the presence of superficial corneal opacities was safe and effective and induced no complications with special precautions.
