Impact of contact lens hygiene risk factors on the prevalence of contact lens-related keratitis in Alexandria-Egypt.

Background: This study aimed at measuring the effect of contact lens hygiene risk factors on the prevalence of contact lens-related keratitis and identifying the specific risk factors to both microbial and non-microbial keratitis independently.

Methods: A cross-sectional study was conducted at Alexandria Ophthalmology Hospital from May to October 2023. All contact lens wearers attending the outpatient clinic had undergone face-to-face interviews using a standardized validated questionnaire which included demographic data and contact lenses (CLs) hygiene risk factors.

Fungal Keratitis: Diagnosis, Management, and Recent Advances.

Fungal keratitis is one of the major causes of microbial keratitis that may lead to corneal blindness. Many problems related to diagnosis and therapy are encountered in fungal keratitis, including difficulty in obtaining laboratory diagnoses and the availability and efficacy of antifungal medications. Intensive and prolonged use of antifungal topical preparations may not be enough.

Femto-SMILE after photo-therapeutic keratectomy in an eye with failed LASIK flap: A case report.

Purpose: The aim of the study is to describe a case where Femtosecond Intrastromal Lenticule Extraction was used to address the refractive defect following topography-guided phototherapeutic keratectomy (topo-PTK) to regularise a scarred corneal surface after an initial LASIK flap formation attempt failed.

Observations: A 23-year-old female experienced a thin and irregular corneal flap, during a microkeratome LASIK surgery of the right eye. Subsequently, she experienced epithelial ingrowth.

Comparison between three different high fluence UVA levels in corneal collagen cross-linking for treatment of experimentally induced fungal keratitis in rabbits.

Introduction: The aim of this study was to compare the efficacy of Photo-Activated Chromophore for Keratitis - Corneal Collagen Cross-linking (PACK-CXL) of three different total UVA fluence levels and topical voriconazole in treatment of fungal keratitis experimentally induced in rabbits.

Methods: This is an interventional experimental study including both eyes of 16 rabbits (32 eyes). Fungal keratitis was induced by intrastromal injection of Fusarium Solani into the cornea.

Suction loss during femtosecond laser-assisted small-incision lenticule extraction: Incidence and analysis of risk factors.

Purpose: To determine the incidence of and analyze risk factors for suction loss during femtosecond laser-assisted small incision lenticule extraction in the management of myopia or myopic astigmatism.

Setting: Roayah Vision Correction Center, Alexandria, Egypt.

Design: Retrospective comparative case-control study.
