The reader must recognize that not all flap interface haze appearing after LASIK represents DLK or infection. Interface fluid is usually the result of elevated IOP, frequently steroid induced. The fluid may be space occupying, resulting in falsely low IOP measurements on applanation tonometry, or non-space occupying, allowing accurate pressure measurement. If presumed DLK does not respond to a regimen of frequent topical steroids, then consider elevated IOP as the etiology (pressure-induced interlamellar stromal keratitis). Management consists of discontinuation of the topical steroid and lowering of the IOP.
