purpose : to evaluate the correlation of central corneal thickness (cct) with refractive error and keratometry in a group of patients eligible for laser keratorefractive surgery, which may serve as a bias in studies on intraocular pressure (iop) measurement methods : in a cross sectional observational study, the right eyes of 340 patients who underwent laser keratorefractive surgery during the ...

purpose : to evaluate the retinal nerve fiber layer (rnfl) and central corneal thickness (cct) in patients with exfoliation syndrome (xfs) methods : in this comparative case series we measures rnfl thickness and cct 30 patients with xfs and 30 age and sex matched healthy subjects who met the inclusion criteria. results : average rnfl in xfs group were significantly thinner than controls (94.36±...

purpose: to compare central corneal thickness (cct) measured by galilei and orbscan ii with that by ultrasonic (u/s) pachymetry in unoperated eyes. methods: cct was measured in 184 unoperated eyes of 92 healthy retractive surgery candidates using galilei, orbscan ii, and u/s pachymetry. considered as a benchmark, measurements by u/s pachymetry were compared to those obtained by the other two de...

purpose : to evaluate central corneal thickness (cct) in patients with juvenile glaucoma and compare it with that of normal individuals methods : a prospective, case-control study was performed on 80 eyes with juvenile glaucoma who attended glaucoma clinic in farabi eye hospital, tehran, iran and 107 clinically normal healthy eyes. standard automated perimetry (sap) was performed for all the pa...

purpose: to compare thickness of central cornea measured using pentacam, orbscan ii, and ultrasound pachymeter methods: patients with no history of corneal diseases or systemic diseases affecting eyes, who did not wear contact lens or use eye medications, and who with no previous history of corneal surgery were selected for this study. central corneal thickness (cct) was measured by three metho...

purpose: to evaluate the effects of smoking on the central corneal thickness (cct). methods: in a historical chohort analytic study, referred cases have been divided into two groups (cigarette smokers, and non–cigarette smokers).  laboratory tests including fasting blood sugar (fbs), blood urea nitrogen (bun); and blood pressure were checked. complete eye examination was performed. cct was meas...

purpose: to evaluate corneal thickness changes after soft contact lens (scl) removal in lasik candidates. methods: fifty lasik candidates (100 eyes) with history of daily wear scl for at least 6 months were enrolled in this descriptive study. central corneal thickness was measured by ultrasonic pachymetry immediately after lens removal and then repeated daily at the same time, until the thickne...

purpose: to assess the agreement of ultrasonic pachymetry, the galilei dual scheimpflug analyzer and orbscan ii in measuring central corneal thickness (cct) in normal and keratoconic eyes. methods: in this prospective comparative study, cct was measured in 88 refractive surgery candidates and 76 (39 right) eyes of 45 keratoconic patients using ultrasonic pachymetry, galilei and orbscanii. readi...

purpose: to compare the preoperative and postoperative measurement of intraocular pressure (iop) using goldman applanation tonometry (gat), the air puff and pascal dynamic contour tonometers (pdct) in eyes undergoing myopic and myopic astigmatic photorefractive keratectomy (prk). methods: in a descriptional -analytic and prospective study, a complete examination was performed at the slit lamp, ...
