Abstract

Purpose. To report an unknown complication of laser in situ keratomileusis (LASIK) surgery. Case Presentation. A 28-year-old female presented with photophobia and glare to our eye service. She stated in her medical history that she had undergone femtosecond assisted LASIK surgery in both eyes 15 months ago and her symptoms started just after this surgery. On admission, her best-corrected visual acuity was 10/10 in both eyes. She had mydriatic pupils with no direct light reflex. Examination of the anterior segment revealed bilateral iris atrophy projecting within the LASIK ablation zone and a transillumination defect was remarkable on the slit lamp examination. Conclusion. We hypothesized that this condition may have been caused by the abnormally increased IOP that resulted in ischemia in the iris vascular plexus during the suction process of surgery.

Highlights

Refractive surgery has undergone significant progress and evolution during the past two decades with the advent of the excimer laser
Many studies have investigated the effects of laser in situ keratomileusis (LASIK) surgery on intraocular pressure and ocular blood flow [2,3,4,5,6]
Yang et al evaluated the effect of intraocular pressure on blood flow velocity and resistance in the rabbit ophthalmic artery, Case Reports in Ophthalmological Medicine

Summary

Introduction

Refractive surgery has undergone significant progress and evolution during the past two decades with the advent of the excimer laser. Excimer laser refractive surgical options mainly include photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) [1]. Since FDA approval in 2000, the femtosecond laser has revolutionized the creation of flaps for LASIK and is being used confidently at the present time. We report an interesting and previously unreported complication of this procedure
