A Rare Case Of Corneal Keloid Following Radial Keratotomy For Myopia

The purpose of this study is to report a rare case of corneal keloid following radial keratotomy for myopia.

This is a case report and literature review.

A 50-year-old male presented with complaints of glare and gradual, painless, progressive diminution of vision in the right eye. Visual acuity in the right eye was 2/60, and slit lamp biomicroscopy revealed a pearly grey-white elevated corneal opacity measuring 4 mm × 3 mm, obscuring the visual axis. There was no history of ocular trauma or infection. The patient had undergone bilateral radial keratotomy for myopia correction 25 years ago. Anterior segment optical coherence tomography imaging demonstrated increased corneal thickness of 1080 µm at the site of lesion and the height of the epicorneal mass was noted to be 493 µm. The patient underwent fibrin glue-aided anterior lamellar keratoplasty. Histopathological examination of the excised host tissue confirmed the diagnosis of corneal keloid.

There are no reports of the development of histopathologically-proven corneal keloid following refractive surgery in the literature. Refractive surgery should be considered a potential risk factor for corneal keloid development.
