A high water content lens (Scanlens 75, +14.5 dioptres) and a low water content lens (Bausch and Lomb Soflens H3, +14.5 dioptres) were compared with respect to corneal thickness response after 6 hours of wear in a provocative test on 12 aphakic eyes. The mean increase in central corneal thickness was 3.3% for Scanlens and 6.4% for Soflens. This difference is statistically highly significant (p ...

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...

AIM To evaluate differences in flap thickness resulting from use of an Alcon Wavelight FS200 femtosecond laser and a MORIA SBK microkeratome when making a 110-µm-thick corneal flap and to identify the potential factors that affect corneal flap thickness. METHODS A prospective case study was performed on 120 eyes of 60 patients who were divided into two groups for LASIK, each group consisting ...

OBJECTIVE To study the effect of 1 drop of combined topical anaesthesia (tetracaine 0.1% and oxybuprocaine 0.4%) on central corneal thickness (CCT) values and at 2.5 mm from the corneal centre in nasal, temporal, superior and inferior hemi meridians, monitored by Orbscan over a period of 16 minutes. MATERIALS AND METHODS The corneal thickness of 12 right eyes of 12 young healthy men was deter...

http://www.avehjournal.org doi:10.4102/aveh.v74i1.307 The purpose of the study was to evaluate central corneal thickness in diabetic patients and to compare the results with controls without diabetes mellitus. Sixty-five diabetic patients (65 eyes) constituted the study group, and 50 eyes were from the healthy control group (50 non-diabetic patients). The study group was subdivided into group 1...

PURPOSE To compare corneal thickness profiles of cross-sections of cornea determined by arc-scanned immersion ultrasound and optical coherence tomography (OCT). METHODS Corneas of 28 eyes from 14 participants were scanned in triplicate using the Artemis 2 high-frequency arc-scanned ultrasound system (ArcScan Inc) and the Visante OCT system (Carl Zeiss Meditec). Corneal thickness and reproduci...

purpose: to evaluate the efficacy of riboflavin administration and ultraviolet a (uva) cross-linking on advanced symptomatic bullous keratopathy (bk). methods: 10 patients with symptomatic pseudophakic bullous keratopathy (pbk) were included. slit-lamp examination, visual acuity, foreign body sensation (fbs) and corneal thickness as measured by pentacam, were performed before corneal cross-link...
