Sustained intraocular pressure-lowering effect and biocompatibility of a single subconjunctival administration of hydrogel-encapsulated nano-brinzolamide

Journal of Materials Science: Materials in Medicine
Brinzolamide is a widely used treatment for glaucoma, but its effectiveness relies on at least twice-daily dosing, which can be challenging for patient adherence.

LIMBAL TRANSPLANTATION AS A METHOD OF LOCAL IMMUNE TOLERANCE INDUCTION IN HIGH RISK KERATOPLASTY

Вестник трансплантологии и искусственных органов, 2011
Activation of destructive adaptive and inherited immunity is the main reason of graft opacification by high-risk keratoplasty. Approximately 46% of recipients from this group are absolute resistant to immunosuppressive therapy with glucocorticoids and ...

Design and Fabrication of a Three-Dimensional Artificial Compound Eye Using Two-Photon Polymerization

Micromachines, 2018
Microlens arrays have been widely used in the fields of micro-optics because of the advantages of their high diffraction efficiency, high fill factor, and wide operating band. However, the microlens array still has problems with its smaller field of view

Micro-optical artificial compound eyes [PDF]

Bioinspiration & Biomimetics, 2006
Natural compound eyes combine small eye volumes with a large field of view at the cost of comparatively low spatial resolution. For small invertebrates such as flies or moths, compound eyes are the perfectly adapted solution to obtaining sufficient visual information about their environment without overloading their brains with the necessary image ...

The Complex Treatment Algorithm for Dry Eye Syndrome with Meibomian Gland Dysfunction. Combination of Intense Pulsed Light (IPL) with Eyelid Hygiene and Artificial Tears

Oftalʹmologiâ, 2020
Nowadays, Meibomian gland dysfunction is considered as the leading cause of dry eye syndrome. Standard methods of the treatment rather often give us only shirt term remission, that’s why so actually to find new alternative treatment options with ...
