PURPOSE To compare the effect of conventional phacoemulsification and femtosecond laser-assisted cataract surgery on the cornea using Scheimpflug imaging and noncontact specular microscopy. METHODS In each group, 38 eyes (38 patients) underwent cataract surgery using either femtosecond laser-assisted (Alcon LenSx laser) (femtolaser group) or conventional phacoemulsification (phaco group). Cen...

PURPOSE To evaluate the changes occurring in the cornea, anterior segment anatomy, and intraocular pressure (IOP) in pregnant women. SETTING Department of Ophthalmology, Assaf Harofeh Medical Center, Zerifin, Israel. DESIGN Prospective single-center comparative study. METHODS The Ocular Response Analyzer dynamic bidirectional applanation device and the Pentacam HR Scheimpflug imaging syst...

Aim: This study focused on exploring the effects of refractive error and its association with various corneal parameters such as curvature (CC), thickness (CT), endothelial cell density (ECD), volume (CV) among young adults in Saudi Arabia.

purpose : to compare changes in posterior corneal elevation, anterior chamber depth (acd), anterior chamber volume (acv) and corneal volume (cv) after laser in situ keratomileusis (lasik ) and photorefractive keratectomy (prk) for low to moderate myopia by pentacam imaging methods : in this prospective comparative case series, 105 consecutive myopic eyes randomly scheduled for lasik (n=59) or p...

PURPOSE To investigate the effect and safety of a selective Rho kinase inhibitor, ripasudil 0.4% eye drops, on corneal endothelial cells of healthy subjects. DESIGN Prospective, interventional case series. METHODS In this study, 6 healthy subjects were administered ripasudil 0.4% in the right eye twice daily for 1 week. Morphological changes and corneal endothelial cell density were examine...

Purpose The purpose of the study is to understand how extracellular stresses, such as ultraviolet (UV) irradiation, affect corneal epithelial cells. Cell volume changes, damage to corneal epithelial integrity, and cellular responses were assessed after exposure to UVC stresses. Methods Primary human and rabbit corneal epithelial cells were exposed to UVC light in culture conditions. Ultraviol...

We evaluated the change in tear film lipid layer thickness, corneal thickness, volume and topography after superficial cauterization of symptomatic conjunctivochalasis. Bilateral superficial conjunctival cauterization was performed in 36 eyes of 18 patients with symptomatic conjunctivochalasis. The mean age of patients (12 males, 6 females) was 68.6 ± 10.9 years (range: 44-83 years). Preoperati...

PURPOSE To analyze single session, intrauser reliability of a Scheimpflug device for anterior chamber (AC) and corneal parameters. METHODS In this observational study, 100 normal candidates underwent Scheimpflug analysis with Sirius 3D Rotating Scheimpflug Camera and Topography System (Costruzione Strumenti Oftalmici, Italy). Two scans in dark room conditions were performed by the same experi...
