PURPOSE Recent investigations have suggested that scleral thinning in mammalian eyes with axial myopia is a consequence of the loss of scleral tissue, rather than the redistribution of existing tissue as the eye enlarges. The present study investigated whether further changes in the distribution and metabolism of scleral tissue occur during the process of recovery from axial myopia. Scleral gly...

This study presents a new mechanical tube cladding process named punch plastic deformation pipe cladding (PPDPC) based on local deformation by pressing a punch into the inner layer of the bimetal tube. To investigate the capability of the process, stainless steel tube (as the inner layer) is bonded to a carbon steel pipe (as the outer layer) to fabricate a bimetal pipe. Shear punch tests were u...

PURPOSE To describe the use of Jupiter scleral lenses (Medlens Innovations, Front Royal, VA; and Essilor Contact Lenses, Inc., Dallas, TX) in the management of keratoconus. METHODS We performed a single-center retrospective chart review of our initial 32 patients with keratoconus evaluated for scleral lens wear. All patients were referred for scleral lens evaluation after exhausting other non...

Presbyopia corrections traditionally have been approached with attempts to exchange power, either at the cornea or the lens planes, inducing multifocality, or altering asphericity to impact the optical system. Treatments that affect the visual axis, such as spectacle and contact lens correction, refractive surgeries, corneal onlays and inlays, and intraocular lenses are typically unable to rest...

A remarkable case of a scleral melting reaction in association with conjunctival rhinosporidiosis is presented and its surgical treatment with a scleral graft described.

PUNCH, the Purdue University Network Computing Hubs, is an infrastructure for network-based VLSI CAD and TCAD that allows users to access and run existing software tools via standard world-wide web browsers. Tools do not have to be written in any particular language, and access to source-code is not required. The PUNCH infrastructure is geographically distributed, but this is transparent to use...

BACKGROUND Dacrocystorhinostomy (DCR) is an operation used to treat nasolacrimal duct obstruction. Essentially there are two approaches: external and endoscopic. Several modalities are used in endoscopic DCR; all aiming to improve success rate, reduce complications, and shorten operative time. Both kerrison punch and drill are widely used in endoscopic DCR with non-conclusive knowledge about di...

A 76-year-old patient experienced a car accident several years earlier that resulted in the loss of his right eye (ocular prosthesis) and retinal detachment left eye, treated with scleral buckle. computed tomography scan head (Fig A) showed bilobed globe separated by ring hyperdensity (scleral buckle). Ultra-widefield fundus imaging B) demonstrated major circular indentation delimiting anterior...
