PURPOSE: To evaluate the efficacy of topical tacrolimus 0.05% as adjuvant therapy to corticosteroids in the treatment of acute endothelial rejection of a penetrating keratoplasty (PKP) graft. METHODS: Patients with the clinical diagnosis of acute endothelial rejection of a PKP graft were randomized into 2 groups-group 1: receiving topical tacrolimus 0.05% as adjuvant therapy to corticosteroid treatment and group 2: receiving only corticosteroid treatment. Main outcome measures were rejection reversal, time to rejection reversal, and recurrence of rejection...

PURPOSE: To evaluate the visual acuity and keratometric and aberrometric changes in patients with corneal transplants (PKP), who underwent topography-guided photorefractive keratectomy (TG-PRK) with mitomycin C (MMC). METHODS: In this case study, 15 patients with spherical equivalents ranging from -11.00 to -0.25 diopters (D) who underwent penetrating corneal transplantation and had irregular astigmatism ranging from -7.5 to -2.0 D underwent TG-PRK with MMC. Corneal topography and wavefront of all patients were measured preoperatively and 12 months postoperatively...

PURPOSE: To investigate the influence of histocompatibility Y (H-Y) antigen matching on corneal graft survival in primary penetrating keratoplasty (PK). METHODS: Medical records of patients who underwent primary PK at Seoul National University Bundang Hospital between June 2005 and October 2015 were retrospectively analyzed. The eyes were classified into 2 groups: H-Y-compatible (115 eyes) and H-Y-incompatible (23 eyes). The H-Y-compatible group included donor/recipient combinations of male/male (57 eyes), female/male (44 eyes), and female/female (14 eyes)...

PURPOSE: To study the morphology of human corneal nerves in eye bank organ-cultured corneas and in corneal grafts post-transplantation. METHODS: Thirty-seven organ-cultured corneas were divided into: Group-A, anterior 300-400 μm of 20 corneas used for Descemets stripping endothelial keratoplasty, and Group-B, 17 full-thickness corneas unsuitable for transplantation. Corneas whole mounts were stained for nerves using acetylcholinesterase technique and examined by NanoZoomer digital pathology microscope...

PURPOSE: To present the different evolution of 2 cases of endophthalmitis caused by Fusarium solani, an aggressive filamentous fungus, depending on the medical and surgical treatment performed. METHODS: We present 2 cases of endophthalmitis caused by Fusarium solani. Topical, intrastromal, intravitreal, and systemic antifungal treatment (natamycin, voriconazole, amphotericin B) failed in both cases. Corneal perforation took place in one of them, being unsuccessfully treated with cyanoacrylate and several amniotic membrane transplants...

AIM: To investigate the anti-(lymph)angiogenic and/or anti-inflammatory effect of itraconazole in a corneal suture model and penetrating keratoplasty (PK) model. METHODS: Graft survival, corneal neovascularization, and corneal lymphangiogenesis were compared among itraconazole, amphotericin B, dexamethasone, phosphate buffered saline (PBS) and surgery-only groups following subconjunctival injection in mice that underwent PK and corneal suture. Immunohistochemical staining and analysis were performed in each group...

AIM: To investigate the histopathologic and morphological changes of the corneas with keratoconus (KC) undergoing penetrating keratoplasty (PKP) according to topographic findings and severity of KC. METHODS: The corneal tissue of 35 samples with KC was retrospectively evaluated with conventional light microscopy. Topographic and pachymetric parameters of keratoconus corneas by means of Pentacam such as mean keratometry (K) and central corneal thickness (CCT) were recorded...

We describe our experience managing a case of fungal keratitis in a 71-year-old immunocompetent woman. Intracameral cultures isolated Magnusiomyces capitatus, a dimorphic commensal microbe with limited pathogenicity, in an immune competent patient. Repeated corneal cultures for bacteria and fungus were negative. Initial broad-spectrum topical fortified antibiotics were eventually escalated to include topical natamycin and voriconazole and oral voriconazole. The patient underwent emergent corneal transplantation, but recurrent infection eventually required anterior chamber washout and intracameral injection of amphotericin B...

PURPOSE: A single-center, cross-sectional study was designed to assess and compare objective and subjective quality of vision of patients intervened with penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK) and Descemet membrane endothelial keratoplasty (DMEK). METHODS: Forty-six patients previously intervened with PK (22 eyes), DALK (7 eyes) and DMEK (17 eyes) were recruited. Visual evaluation included spherical and cylindrical refraction, distance corrected visual acuity (DCVA), photopic contrast sensitivity (CS), optical quality, measured with the HD Analyzer (objective scattering index [OSI], MTF cut-off and Strehl ratio), and ocular and corneal aberrometry, measured with the KR-1W Wavefront Analyzer...

PURPOSE: To review the published literature on outcomes of keratolimbal allograft (KLAL) for the surgical treatment of limbal stem cell deficiency (LSCD) and corneal blindness after severe corneal chemical injury. METHODS: Literature searches were conducted in the following electronic databases: MEDLINE, EMBASE, Science Citation Index, CINAHL, LILACS and the Cochrane Library. Standard systematic review methodology was applied. The main outcome measure was the proportion of eyes with best-corrected visual acuity (BCVA) ≥20/200 at last follow-up...

The case report incorporates a Fourier-domain optical coherence tomography (OCT) examination for demonstration of the existence of pre-Descemet's layer (PDL; Dua's layer) overlying a descemetocele and demonstrates predescemetocele as a separate clinical entity. The prospective analysis was done in two cases that had descemetocele, and OCT demonstrated the presence of PDL over an unruptured descemetocele that offers resilience and can be treated with an elective deep anterior lamellar keratoplasty or a penetrating keratoplasty...

This report describes the macroperforation of descemet's membrane (DM) during irrigation of the interface following successful removal of stromal tissue in big bubble (BB) deep anterior lamellar keratoplasty (DALK). A 42-year-old woman with keratoconus underwent a BB DALK procedure. After successful formation of Type 2 bubble and removal of stromal tissue, interface irrigation was performed to remove residual viscoelastic. This led to a macroperforation of DM, and the case was converted to penetrating keratoplasty...

PURPOSE: To assess the pattern of microbial keratitis after accelerated corneal collagen cross-linkage (aCXL) in patients with keratoconus. METHOD: The medical records of cases of keratoconus that underwent aCXL from June 2014 to May 2017 were reviewed. Cases that developed microbial keratitis after aCXL were included in the study. The clinical, microbiological profile and the treatment outcomes were evaluated. RESULTS: Of 532 eyes that underwent aCXL, 7 cases developed microbial keratitis during the study period...

BACKGROUND: Limbal stem cell transplantation (LSCT) is the definitive treatment for total limbal stem cell deficiency (LSCD). This study evaluates the anatomical and visual outcomes of a surgical technique supplemented by amniotic membrane extract eye drop (AMEED) for in vivo cultivation of limbal stem cells (LSCs). METHODS: One small limbal block (2 × 1 mm) harvested from the contralateral healthy eye was transferred to the diseased eye, which had been already covered by cryopreserved amniotic membrane (N = 20)...

INTRODUCTION: This study aimed to investigate the influence of three muscle relaxants on intraocular pressure (IOP), ocular pulse amplitude (OPA), and vis-à-tergo (VAT) in patients undergoing penetrating keratoplasty (PKP) under general anesthesia. METHODS: Ninety-five patients undergoing PKP were included in this prospective single-center interventional study. IOP and OPA were measured with a dynamic contour tonometer before and 5 min after onset of general anesthesia...
