AIM To compare intraocular pressure (IOP) measurements before and after laser _in situ_ keratomileusis (LASIK) with a femtosecond laser for flap creation using ocular response analyzer (ORA) and Goldmann applanation tonometry, and to identify factors that may influence the preoperative and postoperative IOP. METHODS A prospective study conducted on myopic patients who underwent LASIK using a femtosecond laser for flap ... Read more

ABSTRACT PURPOSE: To examine the clinical association between thyroid gland dysfunction and keratoconus. METHODS: This was a cross-sectional case–control study conducted between May 2018 and July 2019. After performing Pentacam (Oculus Optikgeräte GmbH, Wetzlar, Germany) examination, flat, steep, and maximum simulated keratometric readings were recorded for each patient. Serum concentrations of free triiodothyronine, free thyroxine, and thyroid-stimulating hormone were measured. ... Read more

PURPOSE To compare the safety and efficacy of standard 30 min epithelium-off cross-linking (CXL) versus photorefractive keratectomy (PRK) combined with accelerated epithelium-off cross-linking (AXL) for the treatment of progressive keratoconus (CXL-Plus). METHODS This study was a prospective multicentre comparative clinical study. A total of 125 eyes of 75 patients with grade 1 keratoconus and documented progression were divided into two ...

Aim: Aphakia with insufficient capsular support is a challenging situation that can be managed by multiple options. The purpose of this study is to evaluate iris claw IOL implantation as one available option as regards visual outcome and complications. Methods: This was a prospective interventional study that included 26 eyes of aphakic patients with insufficient capsular support diagnosed preoperatively or ... Read more

URPOSE: To analyze the effectiveness and stability of the refractive, topographic and visual outcomes of the standard cross-linking (SCXL) in keratoconus (KC) management. PATIENTS AND METHODS: This study was designed as a retrospective non-comparative study that included 28 KC patients (n=49 eyes) who performed SCXL as a single procedure to treat KC and completed five-year follow-up period. The topographic, refractive ... Read more

ABSTRACT Purpose: To analyze the visual and refractive outcomes of combined accelerated cross-linking with femtosecond laser intracorneal ring segment implantation for the treatment of pediatric keratoconus. Materials and Methods: This retrospective multicenter noncomparative clinical study included 63 eyes of 37 patients (age, 9–17 years) who underwent between August and September 2016 combined cross-linking with intracorneal ring segment implantation for keratoconus. ...

_Purpose_. To analyze the results of three-year outcomes of combined epithelium-on cross-linking with femtosecond laser ICRS (cross-linking PLUS) for keratoconus management. _Design_. A retrospective multicenter clinical study. _Methods_. 43 eyes of 38 patients were subjected to preoperative and postoperative UCVA, BCVA, refraction, Pentacam pachymetry, and keratometry examinations at 3-, 6-, 12-, 24-, and 36-month follow-up period. _Results_. The preoperative and ... Read more

Abstract AIM: To assess the objective and subjective results of a two-stage procedure for management of keratoconus: clear lensectomy with aspherical intraocular lens (IOL) implantation followed by wave front-guided photorefractive keratotomy (WFG-PRK). METHODS: This prospective interventional non-randomized study included patients aged 35 years old or more with grade I and II stable keratoconus, a clear visual axis, minimal corneal thickness ...

ABSTRACT PURPOSE: To evaluate the effectiveness and safety of combined epithelium-off cross-linking (CXL) with photorefractive keratectomy (CXL Plus) for correction of the myopic and astigmatic components of keratoconus. METHODS: Seventy-nine eyes of 46 patients who underwent CXL Plus were enrolled in this retrospective, multicenter, noncomparative clinical study. Uncorrected distance visual acuity, corrected distance visual acuity, refraction, keratometry, and pachymetry measurements ... Read more

PURPOSE: To establish a consensus in the Egyptian literature on the management of keratoconus (KC) and cataract in the same eye. METHODS: An Egyptian research team, including 42 KC experts, met to develop a protocol for the management of KC in Egypt. In three scientific meetings, the Egyptian Protocol for Keratoconus (EPK) group focused on the diagnosis and treatment of ... Read more
