Transient keratectasia developed in association with a marked intraocular pressure (IOP) elevation in a 26-year-old man who had laser in situ keratomileusis (LASIK) for myopia of -9.0 diopters. The keratectasia subsided promptly after the IOP was normalized by an intravenous administration of mannitol. Keratectasia did not recur. Intraocular pressure(More)
We retrospectively investigated long-term visual recovery in 32 macular reattached eyes which had been followed up for more than five years after surgery. In 17 eyes (53%), the best-corrected visual acuity at 5 years after surgery was > or = 2 lines better than best-corrected visual acuity at 3 months postoperatively. For these 17 eyes, the mean visual(More)
PURPOSE To evaluate the changes in corneal higher order wavefront aberrations after hyperopic laser in situ keratomileusis (LASIK). METHODS In a prospective case series, 15 eyes of 12 patients who had hyperopic LASIK were evaluated. Corneal topography was obtained before and after hyperopic LASIK with a Nidek EC 5000 laser using 5.5/8.0 ablation zones.(More)
Deleterious effects of isopropyl unoprostone (PG-F2 alpha) on the ocular surface were evaluated using the in vivo barrier function assay of corneal epithelial cells and the proliferation assay of human corneal epithelial cells in vitro. The barrier function of corneal epithelial cells in vivo was not impaired by treatment with PGF2 alpha, but it was(More)
PURPOSE To determine the role played by keratinocyte transglutaminase (TG1, TG(K)) in the abnormal keratinization of the cornea. METHODS Vitamin A-deficient rats were produced as a model of severe dry eyes, and the expression of the mRNA and the enzyme activity of TG1 were examined in the corneas. The envelope proteins and keratins of cornified cells were(More)
PURPOSE To evaluate the changes in irregular astigmatism after hyperopic laser in situ keratomileusis (LASIK). METHODS In a prospective case series, 15 eyes of 12 patients who had hyperopic LASIK were evaluated. Corneal topography was obtained before and after hyperopic LASIK. Corneal irregular astigmatism (asymmetry and higher-order irregularity) was(More)
