ocular surface because of the absence of scleral flaps and are more likely to erode through the conjunctiva. Even a microscopic break in the overlying conjunctiva could result in bacterial contamination. It would be worthwhile to compare the incidence of endophthalmitis and suture exposure over the long term with the authors’ technique and the scleral flap method. Ajay Singh, MD Jay M. Stewart,...
متن کاملPosterior Corneal Curvature Assessment after Epi-LASIK for Myopia: Comparison of Orbscan II and Pentacam Imaging
PURPOSE To compare the changes in posterior corneal curvature using scanning slit topography (Orbscan II) and Scheimpflug imaging (Pentacam) before and after Epi-laser in situ keratomileusis (LASIK) for myopia. METHODS In a prospective observational case-series study, 20 myopic patients having undergone Epi-LASIK were examined serially with two different devices, Orbscan II and Pentacam, preo...
متن کاملComparison of anterior chamber depth measurements taken with the Pentacam, Orbscan IIz and IOLMaster in myopic and emmetropic eyes.
PURPOSE This study determined to assess the degree of agreement between anterior chamber depth (ACD) measurements obtained using three different devices and to analyse the relationship between ACD and spherical equivalent (SE) refraction. METHODS In this cross-sectional study, 42 eyes of 42 patients with a mean SE of - 4.69 +/- 4.61 D (range 0.00 D to - 14.88 D) were analysed. Measurements of...
متن کاملCentral corneal thickness, anterior chamber depth, and pupil diameter measurements using Visante OCT, Orbscan, and Pentacam.
PURPOSE To evaluate the agreement among three different optical methods in measuring anterior chamber depth (ACD), central corneal thickness (CCT), and pupil diameter. METHODS One hundred eyes of 50 healthy patients (25 men, 25 women) were enrolled in the study. Mean patient age was 25 years (range: 21 to 32 years). Exclusion criteria were history of any intraocular or corneal surgery, contac...
متن کاملEffect of age, sex, and refractive errors on central corneal thickness measured by Oculus Pentacam®
BACKGROUND Central corneal thickness (CCT) can be used to assess the corneal physiological condition as well as the pathological changes associated with ocular diseases. It has an influence on the measurement of intraocular pressure and is being used as a screening tool for refractive surgery candidates. The aim of this study was to determine the median CCT among normal Pakistani population and...
