Enhancing Visual Acuity through Combined Intraocular Lens Fixation, Penetrating Keratoplasty, and Vitrectomy: The Role of Temporary Landers Wide-Field Keratoprosthesis

Case Reports in Ophthalmology
Introduction: Complex corneal conditions present surgical challenges and necessitate innovation. Here, we present two cases where we performed intraocular lens trans-scleral fixation using the double-needle Yamane technique, followed by penetrating ...

Outcome of a penetrating keratoplasty in a 3-month-old child with sclerocornea

GMS Ophthalmology Cases, 2020
Sclerocornea is a rare congenital anomaly with clouding of the peripheral cornea that possibly extends up to the center of the cornea. Characteristically, a clear distinction (limbus) between sclera and cornea is lacking.

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

Advanced Materials Technologies, EarlyView.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Aniridia‐associated keratopathy: Clinical and molecular mechanisms of disease progression and emerging therapeutic targets

Acta Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare genetic disorder primarily caused by pathogenic variants of the PAX6 gene. It leads to various panocular anomalies, including aniridia‐associated keratopathy (AAK). This review highlights recent insights into its pathogenesis, focusing on clinical staging, microstructural changes in the cornea and molecular ...

Infectious bacterial keratitis management in a Swedish region: Risk factors, treatment and time‐to‐resolution

Acta Ophthalmologica, EarlyView.
Abstract Purpose To report treatment patterns, time‐to‐resolution (TTR) and aetiologies of bacterial keratitis (BK) infections treated in a specialized hospital‐based cornea clinic in Sweden. Methods Retrospective study based on electronic health records screened during the period 2010–2019. The study included only culture‐confirmed cases of BK.

Genetic risk factors in Finnish patients with Fuchs endothelial corneal dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To study the genetic risk factors of Fuchs endothelial corneal dystrophy (FECD) in the Finnish population using hospital‐based and large biobank cohorts. Methods We genotyped a cohort of 107 Finnish patients with FECD for the primary associated genetic risk factor, the TCF4 (CTG)>50 expansion, and studied their clinical phenotype.

Using corneal graft from keratoconic donor for lamellar and penetrating keratoplasties

Indian Journal of Ophthalmology, 2020
We report the use of two corneal grafts derived from a donor, with a history of early stage keratoconus, for lamellar and penetrating keratoplasty. The first graft was used to perform Descemet stripping automated endothelial keratoplasty (DSAEK) in a ...

Corneal transplantation: Restoring sight to the blind

Acta Ophthalmologica, EarlyView.
Abstract Corneal blindness is one of the leading causes of vision loss worldwide. Transplantation of the cornea can restore vision and make blind patients see again. Corneal transplant surgery has undergone major evolution in recent decades with the advent of minimally invasive lamellar surgical approaches such as DMEK and DALK.
