The anterior face of the mouse lens is covered by a layer of epithelial cells. The epithelial cells serve a barrier function at the lens surface and as a progenitor population from which lens fiber cells, the predominant cell type of the lens, are derived. Decreased epithelial cell density is commonly observed during aging and cataract formation in humans and animal models and may contribute di...

In this work, we show how we can improve the image resolution capabilities of a Phase Conjugating (PC) lens as well as the angular resolution of Luneburg lens antennas by employing signal processing techniques such as the Correlation Method (CM), the Minimum Residual Power Search Method (MRPSM), the sparse reconstruction method, and the Singular-Value-Decomposition (SVD)based basis matrix metho...

We investigated the location and severity of lens opacities and epithelial alterations following ultraviolet-B (UVB) irradiation in vivo, using Brown Norway rats. A group of 9 rats received 65 mJ/cm2 UVB irradiation from overhead lamps every 6 days. Lens changes were documented and evaluated by an anterior eye segment analysis system. Lens epithelial cells were examined postmortem in flat prepa...

Introduction: To report by using topical anesthesia for standing phacoemulsification and intraocular lens implantation for two patients who need cataract extraction but unable to lie flat with marked cervical kyphosis due to long-standing ankylosing spondylitis and chronic uveitis. Methods: Two patients are unable to lie flat respectively during phacoemulsification underwent this technique in J...

Purpose To report a case of delayed presentation of a severed acrylic single-piece intraocular lens (IOL) haptic fragment causing corneal edema after uneventful phacoemulsification surgery. Observations An 85-year-old male presented with inferior corneal decompensation six months after a reportedly uneventful phacoemulsification in his left eye. A distal haptic fragment of an acrylic single-p...
