Intraoperative Optical Coherence Tomography (OCT)-Guided Femtosecond Laser-Assisted Descemet Membrane Endothelial Keratoplasty (iFAD).

We describe retrospectively the indications and outcomes of nine patients who present with varying degrees of deep posterior stromal scarring or endothelial failure following deep anterior lamellar keratoplasty (DALK). These patients underwent a surgical strategy coined Intraoperative Optical Coherence Tomography Guided Femtosecond Laser-Assisted Descemet Membrane Endothelial Keratoplasty (iFAD). This strategy can be used to address suboptimal visual outcomes following primary DALK.

One-Step Intraoperative Optical Coherence Tomography Guided Tunnel, Mushroom Femtosecond Laser Big Bubble Deep Anterior Lamellar Keratoplasty.

The aim of our study is to investigate the feasibility and outcomes of using a femtosecond laser (FSL) platform (Ziemer LDV Z8) for deep anterior lamellar keratoplasty (DALK), enabling the creation of mushroom-shaped graft-host junctions, lamellar cuts, and intrastromal tunnels, to facilitate the big bubble, in one step. We included wet lab experiments on nine porcine eyes to assess the laser accuracy and cuts depth using an anterior segment (AS) OCT. This was followed by an interventional prospective case series on 10 eyes with variant corneal pathologies.

Successful Collagen Crosslinking in a Patient With Keratoconus and Systemic Scleroderma.

Scleroderma is an autoimmune disease that affects connective tissue. Keratoconus (KC) is a rare ocular condition that may appear alongside scleroderma. Contact lenses are an essential visual aid for KC patients, especially in advanced cases.

The Protective Effect of Rho-Associated Kinase Inhibitor Eye Drops (Ripasudil) on Corneal Endothelial Cells After Cataract Surgery: A Prospective Comparative Study.

Introduction: Cataract surgery poses a risk to corneal endothelial cells. This study aimed to assess the protective effect of rho-associated kinase inhibitor eye drop (ripasudil) on corneal endothelial cells after cataract surgery over 12 months.

Methods: We conducted a prospective, non-randomized, non-blinded comparative study including 43 patients divided into two groups: the ripasudil group (22 patients, 23 eyes) and the control group (21 patients, 21 eyes).

Pull-through insertion of EndoArt for complex eyes.

Purpose: To report an alternative technique to implant the EndoArt using a pull-through insertion. This technique is helpful in complex eyes, especially in eyes with unstable iris lens diaphragm.

Observation: We present a case of advanced pseudophakic bullous keratopathy with aniridia, previous vitrectomy, and tube implants in which the initial attempt to implant the EndoArt failed, and the device was lost to the vitreous cavity.

Salmon patch-like conjunctival lesion secondary to long-term administration of topical brimonidine: A case report.

Introduction: Brimonidine is a commonly used intra-ocular pressure-lowering agent for glaucoma patients. Allergic follicular or papillary conjunctivitis is a well-known side effect of brimonidine. Brimonidine is associated with ocular allergic symptoms such as conjunctival hyperemia, stinging sensation, photophobia and, in severe cases, corneal erosions.

Three-years outcomes of simultaneous photorefractive surgery and customized corneal cross-linking for keratoconus.

Purpose: To report the efficacy of customized cross-linking (CXL) in halting progression of keratoconus when combined with photorefractive procedures.

Methods: Seven eyes from 7 patients with documented progressive keratoconus were treated with customized CXL (customized ultraviolet-A irradiance pattern centered on the maximum posterior elevation with total energy levels ranging from 5.4 up to 10 J/cm , and an energy fluence of 9 mW/cm) combined with photorefractive procedures.

Femtosecond laser assisted superficial lamellar keratectomy as a successful treatment of corneal opacity in a patient with Thiel Behnke corneal dystrophy.

Introduction And Importance: Thiel Behnke corneal dystrophy (TBCD) and Reis Buckler corneal dystrophy (RBCD) are Bowman's layer dystrophies with overlapping clinical features causing diagnostic confusion. However, each entity has typical histopathological features. We describe in this case the successful use of Femtosecond laser (FSL) in the treatment of TBCD-related corneal opacity.

Paraneoplastic pemphigus associated with rapidly progressing endophthalmitis caused by : A case report.

Introduction: The ocular presentation of paraneoplastic pemphigus (PNP) has rarely been reported in the literature. In this report, we describe a 61-year-old male presenting with eruptive skin lesions associated with underlying non-Hodgkin's lymphoma who had rapid progressive corneal perforation with secondary endophthalmitis in the setting of PNP.

Case Description: A 61-year-old male presented to the emergency department complaining of skin eruption mimicking Stevens-Johnson syndrome, which was later found to be related to PNP.

Histopathological assessment of optic nerve invasion guided by radiological findings in enucleated globes with retinoblastoma.

Background: Optic nerve (ON) invasion is an important high-risk feature, and an indicator for neoadjuvant chemotherapy and prognosis. We aim through this study to correlate the detected-ON invasion by Magnetic resonance imaging (MRI) with the corresponding confirmed histopathological level of invasion.

Methods: A retrospective study of enucleated globes with the diagnosis of retinoblastoma received in the histopathology department(s) from January 2015 to December 2016 (2 years).
