Objective: To compare visual outcomes after cataract surgery using three intraocular lenses (IOL) of different prices but similar properties.

Methods: A comparative study with retrospective data of patients operated for phacoemulsification with monofocal IOL implants was carried out at Al-Ibrahim Eye Hospital (AIEH) from April 2021 to Feb 2022. Patients with diabetes, any preoperative ocular morbidity and unclear diagnosis were excluded from the study.

Background: Minimally invasive glaucoma procedures are emerging as clinically effective and safe glaucoma management approaches; however, evidence regarding quality-of-life outcomes is limited.

Objectives: To explore the impact of minimally invasive glaucoma surgery (MIGS) combined with phacoemulsification on patient-reported outcomes and clinical parameters related to ocular surface disease in people with glaucoma.

Design: Retrospective observational study.

Background: Minimally invasive glaucoma surgery (MIGS), including minimally invasive bleb surgery (MIBS), is a rapidly evolving area of research and clinical interest in ophthalmology. The growing number of devices has necessitated evaluations to identify subtle differences in outcomes between treatments.

Objectives: To compare clinical effectiveness and safety outcomes of iStent combined with endoscopic cyclophotocoagulation (ICE2) with bleb forming PreserFlo MicroShunt (PMS) and XEN-45 gel implant in a 24-month retrospective review.

Background And Objective: Age-related macular degeneration (AMD) is one of the most common reasons for blindness in the world today. The most common treatment for wet AMD is the intravitreal injections for inhibiting vascular-endothelial-derived growth factor (VEGF). This treatment usually involves multiple injections and thus multiple clinic visits, which not only causes increased cost on national health services but also causes exposure to the hospital environment, which is sometimes high risk considering current COVID crisis.

A 60-year-old man recently admitted for bipedal oedema, endocarditis and a persistently positive COVID-19 swab with a history of anticoagulation on rivaroxaban for atrial fibrillation, transitional cell carcinoma, cerebral amyloid angiopathy, diabetes and hypertension presented with sudden onset diplopia and vertical gaze palsy. Vestibulo-ocular reflex was preserved. Simultaneously, he developed a scotoma and sudden visual loss, and was found to have a right branch retinal artery occlusion.

Aims: To evaluate primary periocular basal cell carcinomas (BCCs) in depth including comparing histological margins with subtype, location and surgical specialty after wide local excision.

Methods: A retrospective review was performed for all BCCs excised from three hospitals over 5 years, covering a population of just over 1 million. Tumours were classified according to histological subtype location.

Background: Retinal vein occlusion is frequent cause of visual loss with insufficient treatment options. Many treatment options have been tried in the past including intravitreal triamcenoloneacetonide injection. This study was conducted to evaluate the efficacy and complications of intravitreal injection of Bevacizumab in different types of retinal vein occlusion.

Background: Hypertropia is a condition in which one eye is elevated relative to the other, either intermittently or constantly. It causes significant problem either cosmetically or by abnormal head posture and thus needs to be corrected surgically. This study was conducted to evaluate the success rate and complications of isolated inferior oblique myectomy in patients with hypertropia.
