Reconstruction of deep and perforating corneal defects in dogs—A review (Part II/III): Biomaterials and keratoprosthesis

Veterinary Ophthalmology, Volume 28, Issue 2, Page 532-542, March 2025.
Abstract The surgical reconstruction of severe corneal ulcers is a common and crucial component of the clinical practice of veterinary ophthalmology. Numerous surgical techniques are used in dogs for corneal reconstruction, and these techniques may be categorized by the material used to repair the corneal lesion.

Chiral Nanoparticles Suppress Inflammatory Infiltration to Promote Extracellular Matrix Remodeling for Ectopia Lentis Therapy

Advanced Science, Volume 13, Issue 58, 19 October 2026.
L‐cysteine‐configured chiral polyurethane nanoparticles suppress ocular inflammation and reduce extracellular matrix (ECM) degradation in ectopia lentis by regulating macrophages polarization and inhibiting nuclear factor kappa B signaling pathway. By promoting zonular fiber‐associated protein restoration and tissue repair, this minimally invasive ...

Simulation of visual perception and learning with a retinal prosthesis

, 2017
The nature of artificial vision with a retinal prosthesis, and the degree to which the brain can adapt to the unnatural input from such a device, are poorly understood.

Erectile response to intracavernous injection of vasoactive drugs after penile prosthesis removal [PDF]

, 1990
Two patients with a history of penile prosthesis removal presented for non-prosthetic treatment of their erectile dysfunction. The first patient had a penile implant for two years before it was removed and showed extensive cavernosal fibrosis. He did not

Nanoparticle-based optical interfaces for retinal neuromodulation: a review

Frontiers in Cellular Neuroscience
Degeneration of photoreceptors in the retina is a leading cause of blindness, but commonly leaves the retinal ganglion cells (RGCs) and/or bipolar cells extant.

Safety of a suprachoroidal retinal prosthesis

, 2014
© 2015 Dr. Ronald LeungLight is transformed into neural signals by the retina. Certain conditions, such as retinitis pigmentosa, can cause extensive degeneration of the outer retinal layers, resulting in profound vision impairment.
