BACKGROUND Several authors reported incorrect high intraocular pressure (IOP) values in eyes with a thick cornea using applanation tonometry. This hypothesis was checked by comparing applanation tonometry with direct intracameral manometry. METHODS 73 patients, scheduled for intraocular surgery, were enrolled. Immediately before surgery, the following were registered: (i) central corneal thic...

PURPOSE We report endothelial cell (EC) characteristics and central corneal thickness (CCT) from the Infant Aphakia Treatment Study (IATS) patients at the 5-year examination. DESIGN Randomized, controlled trial of the treatment of unilateral cataract with aphakic contact lens (CL) versus primary intraocular lens (IOL) implant. PARTICIPANTS A total of 114 infants with unilateral cataract. ...

AIM To compare the anterior segment measurements obtained by rotating Scheimpflug camera (Pentacam) and Scanning-slit topography (Orbscan IIz) in keratoconic eyes. METHODS A total of 121 patients, 71 males (58.7%) and 50 females (41.3%) (214 eyes) with the diagnosis of keratoconus (KC) were enrolled in this study. Following diagnosis of KC by slit-lamp biomicroscopic examination, central corn...

BACKGROUND/AIM To compare intraocular pressure (IOP) measurements taken by the Goldmann applanation tonometer, the Tono-Pen and the ocular blood flow pneumotonometer in eyes with varying central corneal thickness (CCT) due to penetrating keratoplasty (PK), keratoconus (KC), and Fuchs' endothelial dystrophy (FED). METHODS IOP was measured with the Goldmann applanation tonometer, Tono-Pen XL, a...

OBJECTIVES To compare intraocular pressure (IOP) measurements made by Goldmann applanation tonometry (GAT) and dynamic contour tonometry (DCT). METHODS IOPs were measured by GAT and DCT in 63 eyes of 63 healthy subjects. A comparison was made by intraclass correlation coefficient. Passing-Bablok plot was constructed to establish the existence of systematic and/or proportional biases. Multivar...

PURPOSE To determine corneal biomechanical properties in patients with high myopia. DESIGN Observational study. METHODS High myopia patients (n=45, age: 37.0+/-12.6 years) with refractive errors of spherical equivalent (SE) greater than -9.00D were recruited in this study along with healthy subjects (n=90, age: 33.7+/-12.4 years) with refractive errors of SE ranging from 0D to -3.00D. Only ...

Abstract Aim: To compare corneal thickness measurements made at different times and to evaluate their dependence on individuals. Materials Methods: The central of the right eyes 30 healthy young adults was measured by first investigator three Anterior Segment Optical Coherence Tomography (AS-OCT) method. In addition, fourth were second researcher a time. obtained values compared. Results: mean ...

PURPOSE To investigate the correlation coefficients between intraocular pressure (IOP) before and after adjusting for central corneal thickness (CCT) and corneal biomechanical properties. PATIENTS AND METHODS A total of 218 eyes of 218 patients with primary open-angle glaucoma (mean age =71.5 years; mean spherical equivalent =-0.51 D; mean deviation determined by Humphrey visual field analyze...

PURPOSE To assess the diagnostic power of the Corneal Visualization Scheimpflug Technology (Corvis ST) provided corneal biomechanical parameters in keratoconic corneas. METHODS The following biomechanical parameters of 48 keratoconic eyes were compared with the corresponding ones in 50 normal eyes: time of the first applanation and time from start to the second applanation [applanation-1 time...

Background. To evaluate the effects of corneal glyceraldehyde CXL on the rabbit bullous keratopathy models established by descemetorhexis. Methods. Fifteen rabbits were randomly divided into five groups. Group A (n = 3) is the control group. The right eyes of animals in Groups B,C, D, and E (n = 3, resp.) were suffered with descemetorhexis procedures. From the 8th day to the 14th day postoperat...
