purpose: to evaluate the correlation between corneal power and corneal horizontal white to white diameter in myopic patients scheduled for lasik surgery. methods: overall, in 840 eyes of 420 myopic subjects scheduled for lasik, horizontal white to white diameter and mean corneal power were obtained using orbscan ii. pearson correlation test and regression analysis were used to detect any correl...

purpose : to determine the efficacy of fibrin glue in corneal perforations up to 3 mm in diameter methods : a case series study was performed on corneal perforations up to 3 mm who were admitted at farabi hospital- tehran. age, visual acuity, presence and size of corneal thinning, corneal epithelial defect, size and depth of corneal infiltration, site and size of corneal perforation, corneal va...

PURPOSE To determine the normal distribution of corneal diameter in a 40- to 64-year-old population and its association with other biometric components. METHODS In a cross-sectional population-based study, subjects were selected through multistage cluster sampling from the 40- to 64-year-old citizens of Shahroud in northern Iran. After obtaining informed consents, optometry tests including re...

PURPOSE To determine the horizontal corneal diameter, central corneal thickness, and axial length in premature infants. METHODS Infants with a birth weight of less than 2,500 g or with a gestation period of less than 36 weeks were included in the study. Infants with retinopathy of prematurity (ROP) were allocated to Group 1 (n=138), while those without ROP were allocated to Group 2 (n=236). A...

The size of the cornea is important in the diagnosis of primary infantile glaucoma. Reference values regarding eyes of premature infants are scarce. Such data are of special importance in areas such as the Middle East where infantile glaucoma is common and often evident already at birth. The authors have measured the horizontal corneal diameter of the eyes of 127 premature Saudi infants with a ...

The survival of donor corneal epithelium was investigated in rabbits after they received unilateral 8 mm diameter lamellar keratoplasties with living donor tissue of a different sex from the host. Three weeks, 6 weeks, and 12 weeks postoperatively, cultured corneal epithelia, grown from 5 mm diameter central buttons, the adjacent 0.75 mm wide donor rings, the peripheral 10 to 13 mm diameter rin...
