Hyaluronan in Ocular Surface Health and Disease: From Biological Mechanisms to Therapeutic Applications

Proteoglycan Research, Volume 4, Issue 4, October 2026.
ABSTRACT Hyaluronan (HA) is an ubiquitous non‐sulfated glycosaminoglycan with unique physicochemical and biological properties that underpin its essential roles in tissue homeostasis, repair, and diseases. First identified in the vitreous humor of the eye, HA has a long‐standing history in ophthalmology as a key component of ophthalmic visco‐surgical ...

DNA Origami Uptake in Y‐79 Retinoblastoma Cells Driven by Oligolysine Coating

Small Structures, Volume 7, Issue 10, October 2026.
We show that polymeric coating can enable DNA origami nanoparticle internalization into ocular retinoblastoma cells. Not only are the coated nanoparticles well‐tolerable to the cells, but they also remain mobile in the vitreous of a porcine ex vivo model.

Prevention and correction of residual refractive errors after cataract surgery

Journal of Clinical Ophthalmology and Research, 2017
Cataract surgery today has become more of a refractive surgery with high patient expectations and demand for independence from glasses. With advances in biometry, precise intraocular lens (IOL) power calculation is the most important step in achieving ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, Volume 7, Issue 5, October 2026.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Neurotrophic Signaling, Sleep Physiology, and Retinal Neuroprotection: Integrative Mechanisms and Therapeutic Implications for Glaucoma

Sensory Neuroscience, Volume 2, Issue 3, September 2026.
Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

Clinical Efficacy and Complications of Intraocular Lens Exchange for Opacified Intraocular Lenses [PDF]

Korean Journal of Ophthalmology, 2008
To evaluate the clinical efficacy and complications of intraocular lens (IOL) exchange.A review of medical records was performed for 52 eyes that had undergone an IOL exchange due to IOL opacification. Surgical complications and their incidences were analyzed.
