Refractive surgery followed by CK may lead to perforation

Care must be taken to prevent conductive keratoplasty-treated spots from coinciding with areas in the corneal stroma that might have been altered with previous refractive procedures, a group of Greek ophthalmologists has warned.
George D. Kymionis, MD, PhD, and colleagues described a case in which a 56-year-old woman had CK for residual hyperopia and astigmatism. Three years before, she had undergone arcuate keratotomy, followed 2 years later by LASIK for high astigmatism correction. During CK, the right eye suffered a corneal perforation and an iris perforation, and anterior subcapsule opacification was seen beneath the perforation site. The injury was managed with a bandage contact lens, and 3 months postop, uncorrected visual acuity in both eyes was 20/32; best-corrected visual acuity was 20/20.
The case report is published in the Journal of Cataract & Refractive Surgery.
