Anterior capsular contraction syndrome is an uncommon but well-known complication associated with continuous curvilinear capsulorhexis performed during cataract surgery. It remains asymptomatic unless the constriction progresses to involve the visual axis or causes late intraocular lens-related complications. A male patient in his 50s presented with severely decreased vision in his right eye 2 years after uneventful cataract surgery. Slit-lamp biomicroscopy revealed capsular phimosis and a dense, central, fibrous plaque with total occlusion of the anterior capsulorhexis opening. Neodymium-doped yttrium aluminium garnet laser anterior capsulotomy and vitrectorhexis were attempted, but proved ineffective. Surgical excision with manual cutting of the fibrotic membrane was performed, successfully clearing the visual axis and restoring vision.

Background: To evaluate the biosafety, reduction in anterior capsule opacification, and fluctuation in intraocular pressure (IOP) of a new phakic refractive lens (PRL) with a sinusoidal drainage groove design.
Methods: This self-controlled experiment was performed on eight eyes of four rabbits. Each rabbit was implanted with a sinusoidal PRL (PRL-S5) in the right eye and a conventional posterior chamber PRL (PC-PRL) in the left eye.
Lens tension is essential for accommodative vision but remains challenging to measure with precision. Here, we present an optical coherence elastography (OCE) technique that quantifies both the tension and elastic modulus of lens tissue and capsule. This method derives mechanical parameters from surface wave dispersion across a critical frequency range of 1-30 kHz.

Study Design: This study employed a patient-specific finite element model.
Purpose: To quantify the effect of anterior and posterior surgical approaches on adjacent segment biomechanics of the patient-specific spine and spinal cord.
Overview Of Literature: Adjacent segment degeneration (ASD) is a well-documented complication following cervical fusion, typically resulting from accelerated osteoligamentous deterioration and subsequent symptomatic neural compression.

Background: One of the significant challenges that can arise during cataract surgery is the occurrence of posterior capsule rupture (PCR) and vitreous loss. It may result in different complications including cystoid macular edema, endophthalmitis, glaucoma, and considerably retinal detachment which consequently contributes to poor functional outcomes.
Methods: This study was a prospective double blinded randomized clinical trial including 42 patients with previous complicated cataract surgery including posterior capsular rupture and consequently vitreous loss that anterior vitrectomy was done for them.

Background: Arthroscopic repair is recommended for patients with bony Bankart lesions to restore anterior shoulder stability and avoid recurrent glenohumeral instability. The aim of this study was to investigate the clinical and radiological outcomes of patients following arthroscopic bony Bankart repair using a single suture anchor fixation technique named the "door-locking" technique.
Methods: From January 2017 to February 2024, a consecutive series of 22 patients with acute bony Bankart lesions underwent shoulder arthroscopy.
