CASE REPORT We report the case of a 34 year-old man with progressive loss of visual acuity in his left eye, who was diagnosed with pigmentary glaucoma with an intraocular pressure of 32mmHg. Eight years previously, the patient had undergone refractive surgery (LASIK). Hypotensive treatment led to a significant refractive change accompanied by flattening of the corneal curvature. DISCUSSION We...

PURPOSE To compare geometrical shape factors of keratoconus corneas after cross-linking (CXL) by means of Scheimpflug imaging with those of untreated fellow eyes. SETTING Institut für Refraktive und Ophthalmo-Chirurgie, Zürich, Switzerland. METHODS Scheimpflug imaging of the anterior segments was performed with the Pentacam (Oculus, Wetzlar, Germany) in 21 patients with progressive keratect...

A prospective study of corneal stiffness parameter 174 eyes healthy subjects with different refractions as well 56 keratoconus was carried out. The groups were comparable in age and gender composition. Correlation performed between (Stiffness Parameter (SP-A1), minimum thickness (MCT) biomechanically compensated intraocular pressure (bIOP) determined using Pentacam HR Corvis ST (OCULUS, Germany...

sepsis and septic shock are among mortality causes following major surgeries. the charlson co-morbidity index consists of 19 weighted categories related to chronic health which measures the burden of co-morbidity. the goal of this study was to determine the incidence of postoperative sepsis in patients underwent gynecological and gastrointestinal cancer surgeries and predictive role of charlson...

PURPOSE Corneal thinning disorders weaken the mechanical strength of affected corneas, suggesting that photorefractive procedures may be contraindicated in keratoconus. Few cases have been reported to confirm this hypothesis. METHODS A 45-year-old man had two laser in situ keratomileusis (LASIK) procedures and one photorefractive keratectomy (PRK) performed on his left eye, and three LASIK pr...

PURPOSE In this case report, we describe the surgical procedure of corneal inlay preparation and corneal pocket creation using a femtosecond laser system. CASE REPORT A 7-year-old girl who presented with unilateral paracentral corneal thinning underwent the surgical procedure of corneal inlay. Preoperatively, the refraction was +10.00-6.00 × 170. One month after the procedure, astigmatism and...

The patient presented herein is a 52-year-old woman suffering from primary open angle glaucoma (POAG) in both eyes. She has no history of systemic disorders and is not on any systemic medications. She underwent laser in situ keratomileusis (LASIK) 9 years ago for refractive error of -5.50-3.00×180 in both eyes, and was diagnosed with glaucoma 7 years afterwards. Her ocular examination when I sa...

PURPOSE The aim of this study was to review the safety and stability of cornea cross-linking (CXL) for the treatment of keratectasia after Excimer Laser Refractive Surgery. METHODS Eligible studies were identified by systematically searching PubMed, Embase, Web of Science and reference lists. Meta-analysis was performed using Stata 12.1 software. The primary outcome parameters included the ch...

LASIK (laser-assisted in situ keratomileusis) is a common laser refractive procedure for myopia and astigmatism, involving permanent removal of anterior corneal stromal tissue by excimer ablation beneath a hinged flap. Correction of refractive error is achieved by the resulting change in the curvature of the cornea and is limited by central corneal thickness, as a thin residual stromal bed may ...
