Elevated intraocular pressure-induced interlamellar stromal keratitis occurring 9 years after laser in situ keratomileusis.

Elevated intraocular pressure-induced interlamellar stromal keratitis (PISK) is an entity of interface haze usually occurring weeks to months after laser in situ keratomileusis (LASIK) that is associated with elevated intraocular pressures and worsening with steroid treatment. There is evidence that this interface haze is the result of abnormal fluid dynamics that occur in the cornea after LASIK. We present a case of pressure-induced interlamellar stromal keratitis occurring 9 years after LASIK in the setting of anterior uveitis. This case emphasizes the importance of considering such diagnoses as pressure-induced interlamellar stromal keratitis in the differential diagnosis when presented with a patient with corneal haze and a history of LASIK.
