Purpose: To compare implantable collamer lenses (ICLs) and acrylic implantable phakic contact lenses (IPCLs) in the treatment of myopia in adults, as regards refractive outcome and adverse effects.
Methods: Prospective, randomized comparative study with phakic intraocular lenses (IOLs) was carried out for treatment of myopia. Patients were randomized into two groups: one for ICL and the other for IPCL.
Purpose: To compare the benefits and side effects of pars plana vitrectomy with those of systemic immune modulator therapy for patients with complicated intermediate uveitis.
Methods: This prospective clinical trial enrolled patients with recurrent intermediate uveitis who exhibited minimal improvement of visual acuity, despite injections of periocular steroids. Twenty patients were randomized to the pars plana vitrectomy group or oral steroid and cyclosporine-A group (10 eyes of 10 patients per group).
Purpose: To evaluate the outcomes of Lasik with aspheric ablation profiles and a micro-monovision protocol for correction of presbyopia in pseudophakic patients.
Patients And Methods: This study included 50 pseudophakic eyes of 25 patients. Full ophthalmic examination, dominant eye tests and tests for tolerance of anisometropia (1 or 2 diopters) were done preoperatively.
Purpose: To evaluate clinical efficacy of combined sulphur hexafluoride (SF6) gas tamponade and laser photocoagulation for optic disc pit maculopathy (ODPM).
Methods: Eleven eyes of nine patients with optic disc pit maculopathy were treated with intravitreal injection of 0.6 ml 100% sulphur hexafluoride (SF6) combined with laser photocoagulation treatment.
Introduction: Both primary osteoarthritis (OA) and age-related macular degeneration (AMD) cause disability in old people. This study aimed to detect the relation between primary osteoarthritis and age-related macular degeneration in a sample of geriatric Egyptian population.
Methods: This cross-sectional study included 222 primary OA patients.
Purpose: To study the ability of pattern reversal visual evoked potentials (VEPs) to detect subclinical visual pathway pathologic assessment in Behcet disease (BD) and correlate VEP results in BD with disease activity and response to corticosteroid treatment.
Methods: This study included 18 patients (36 eyes) with BD without recent ocular manifestations and 20 healthy controls (40 eyes). Clinical history was taken, and clinical examinations were done.
Purpose: To evaluate the different IOP readings by Goldmann applanation tonometer (GAT), ICare rebound tonometer, and Tono-Pen in keratoconus patients after MyoRing implantation. To assess the influence of central corneal thickness (CCT) and thinnest corneal location (TCL) on IOP measurements by different tonometers.
Setting: Prospective observational study was conducted in two private centers in Egypt from February 2015 to November 2016.
Purpose: To evaluate circular neodymium: YAG laser incision in cases of anterior capsular contraction syndrome (ACCS) by comparing it to radial Neodymium: YAG laser incision as for efficacy and safety.
Settings: Ophthalmology Department, Benha University Hospitals.
Methods: The study was done on 74 eyes of 66 patients with symptomatic ACCS.
Objectives: To study the macular microstructural changes and their relationship to visual acuity (VA) following primary vitrectomy and silicone tamponade for retinal detachment.
Patients And Methods: A total of 40 cases with macula-off rhegmatogenous retinal detachment underwent 23-gauge vitrectomy with silicone oil tamponade. Cases with open globe injury and other ocular pathology were excluded.
Purpose: To evaluate femtosecond laser in flap and cap creation, detect some corneal biomechanical changes, and evaluate dry eye after laser in situ keratomileusis (LASIK), Femto-LASIK, and small incision lenticule extraction (SMILE) with 3-year follow-up.
Patients And Methods: Preoperative evaluation taken: full ophthalmic examination, Pentacam, ocular response analyzer, ocular surface disease index (OSDI), and tear breakup time (TBUT). LASIK flap was created using Moria microkeratome in 30 eyes (LASIK group) and using VisuMax femtosecond laser in 38 eyes (FS-LASIK group) and SMILE was done by VisuMax in 35 eyes (SMILE group).
Background: Convergence Insufficiency (CI) is a common binocular vision disorder characterized by exophoria more at near than at far, a receded Near Point of Convergence (NPC), and decreased Positive Fusional Vergence (PFV) at near. This disorder is often associated with several symptoms that may disturb the person's quality of life. Therefore, diagnosis and treatment of CI is a vital issue.

Settings: Ophthalmology department, Benha University hospitals, Egypt.
Methods: Twelve eyes of 12 patients with PLE, 30 eyes of 30 patients with KC, 25 eyes of 25 subjects with uncomplicated Lasik and finally 25 eyes of 25 healthy subjects as a control group were studied.
Introduction: The objective of this study was to evaluate the changes of the anterior chamber (AC) of the eye after implantable Collamer lens (ICL) implantation in high myopia by using the Pentacam.
Methods: The prospective study included 34 high myopic patients (34 eyes). All patients were treated with Visian implantable Collamer lens (ICL) (Staar Surgical Co.
