1. Abstract Corneal refractive surgery is a promising technique to correct irregularities of cornea shape accompanying various types of aberration in eye ball system, and correction of refractive power for nearsightedness and farsightedness are fundamental application of refractive surgery. However there have been reported some risks such as over-/under-corrections, abnormal sight symptom like ...

Keratometric measurements were made from 38 kittens and cats in a closed breeding colony. Data were obtained on changes of radius of curvature of the cornea as a function of age and weight. The measurements also provided data on estimated changes with growth of corneal astigmatism.

background : the aim of this study was to investigate the association between the two most commonly used generic and disease specific health-related quality of life (hrqol) measures in patients with chronic lung disease due to sm: medical outcomes study short form 36-item (sf-36) and st george's respiratory questionnaire (sgrq). methods : this is a secondary analysis of iranian chemical warfare...

AIMS For the study of transcorneal in vitro permeation of ophthalmic drugs, excised animal cornea or corneal epithelial cell culture are frequently used as a replacement for the human cornea. The main purposes of this study were to reconstruct a complete human organotypic cornea equivalent, consisting of all three different cell types (epithelial, stromal, and endothelial); to test the barrier ...

Harlequin ichthyosis is a rare congenital autosomal recessive disorder that causes hyperkeratosis or plate-like keratosis. Hyperkeratosis affects both upper and lower eyelids defective eyelids. Lagophthalmos persistent dry eye will cause desiccation of the cornea, possibly leading to complications such as ectropion, cornea ulceration, corneal perforation, etc. requires regular ocular review pre...

Macromolecules from normal rabbit cornea and cornea containing a 2-mm diameter button of scar tissue were biosynthetically labeled with 35S-sulfate and 3H-glucosamine in vivo and in organ culture. Labeled macromolecules, including proteoglycans (PGs) extracted from the normal cornea, scar tissue, and corneal tissue adjacent to the scar with guanidine hydrochloride were chromatographed on DEAE-S...

PURPOSE We investigated the expression of laminin-5 and integrins, and the ultrastructure of the interface between basal cells and the basement membrane in the keratoconus cornea. These findings were compared to those in normal central cornea and limbus. METHODS Frozen sections of the normal cornea (center and limbus) and the keratoconus cornea were immunostained with monoclonal antibodies ag...
