Keratoglobus is a rare subset of noninflammatory corneal ectasia, which is a group of disorders characterized by corneal thinning, projection, and scarring. Patients with keratoglobus commonly present with poor vision. A case of advanced keratoglobus was managed by a modified phacoemulsification surgical technique using endoillumination and capsular staining with trypan blue. In this case, we present a 54-year-old man with keratoglobus. In January 2023, a modified phacoemulsification surgical technique using endoillumination was described with a video in a patient with bilateral corneal opacification, neovascularization, significant peripheral thinning, and moderate to severe corneal opacity in which cataract surgery had to be performed alone without considering penetrating keratoplasty...

The aim of this study is to investigate the relationship between age-related macular degeneration (AMD) and lymphangiogenesis biomarkers, namely LYVE-1, Podoplanin, VEGF-C, VEGFR-2 and VEGFR-3. This prospective and interventional study includes 30 patients with AMD which may be dry or wet type and 30 controls for whom vitrectomy and phacoemulsification was indicated due to additional pathologies (epiretinal membrane, macular hole, retinal detachment, and cataract). 0.1-0,2 ml of aqueous humor and 0.5-1 ml of vitreous sample was taken during the operations...

Visual acuity was light perception...

BACKGROUND: Primary Angle Closure Glaucoma (PACG), is caused by narrowing the iridocorneal angle and increases the risk of blockage in the trabecular meshwork. Phacoemulsification and laser peripheral iridotomy (LPI) effectively control IOP elevation and widen the angle. This systematic review and meta-analysis compared Phacoemulsification and LPI Effectiveness for PACG. METHODS: We searched Medline, Embase, and CENTRAL. We included randomized controlled trials (RCTs) that compared Phacoemulsification and LPI for individuals with PACG...

PURPOSE: Evaluate the impact of high vs low intraoperative IOP during phacoemulsification on anterior and posterior physiology. SETTING: Private practice in Des Moines, Iowa. DESIGN: Prospective, randomized, paired-eye clinical trial of patients anticipating bilateral cataract surgery. METHODS: Twenty-seven subjects randomized at the time of their first cataract surgery to either low intraocular pressure (IOP) or high IOP group...

The aim of the study was to compare the anterior segment parameters after cataract surgery in pseudoexfoliation syndrome (PEX) and control eyes. We conducted a prospective comparative study of 36 eyes (PEX group), 16 eyes (PEXG group) and 46 eyes (control group) of 98 patients after phacoemulsification with intraocular lens implantation. Before surgery, 1 week, 1 month and 3 months postoperatively, anterior chamber parameters were evaluated by swept source anterior segment optical coherence tomography (AS-OCT)...

PURPOSE: To assess the association between vitreous hyper-reflective dots (VHD) and the macular thickness changes following uneventful phacoemulsification. METHODS: In this prospective cohort study optical coherence tomography (OCT) examinations were performed preoperatively and 1 week, 1 month and 3 months postoperatively in patients undergoing cataract surgery. OCT images were analyzed for retinal central subfield thickness (CST) and preretinal VHDs. Surgeries were recorded for the assessment of lens fragments in the space of Berger...

OBJECTIVES: To assess the visual improvement and mean residual astigmatism in patients who underwent cataract surgery with toric intraocular lens. METHODS: The retrospective, observational study was conducted at the Department of Ophthalmology, Aga Khan University Hospital, Karachi, and comprised data from January 1, 2018, to December 31, 2020, related to adult patients who had regular astigmatism of at least 0.75D and underwent cataract surgery with toric intraocular lens implantation using a digital marker...

INTRODUCTION: The production of ultrasonic energy during phacoemulsification is associated with heat generation that could damage ocular tissues, particularly at the corneoscleral wound site. CASE PRESENTATION: This study presents an 89-year-old patient with senile hypermature cataract and Fuchs endothelial dystrophy developing severe thermal corneoscleral injury during phacoemulsification. At presentation, visual acuity was finger count at 40 cm and there was a 1 × 2-mm area of corneal melting at the corneal tunnel with diffuse corneal oedema...

The complete safety and efficacy of endoscopic cyclophotocoagulation (ECP) remain unclear in the literature and, to our knowledge, there are no current meta-analyses on phaco-ECP versus phacoemulsification alone to date. Thus, we conducted a systematic review and meta-analysis comparing these two strategies through studies, assessing the effectiveness and safety of outcomes in a population with glaucoma. The protocol for this systematic review was registered in the PROSPERO International Prospective Register of Systematic Reviews (CRD42023482376)...
