Silicone resin: rightSilicone oil: A silicone oil is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane.Silastic: Silastic (a portmanteau of 'silicone' and 'plastic') is a trademark registered in 1948 by Dow Corning Corporation for flexible, inert silicone elastomer.Breast prosthesesOptic disc pit: An optic disc pit is a congenital excavation (or regional depression) of the optic nerve head resulting from a malformation during development of the eye. Optic pits are important because they are associated with posterior vitreous detachments (PVD) and even serous retinal detachments.Soft lithography: In technology, soft lithography refers to a family of techniques for fabricating or replicating structures using "elastomeric stamps, molds, and conformable photomasks".In the words of Rogers and Nuzzo, p.Pars plana: The pars plana is part of the uvea, choroidea, one of the three layers that comprise the eye. As a part of the ciliary body, it is about 4 mm long, located near the point where the iris and sclera touch and is scalloped in appearance.Siloxane: A siloxane is a functional group in organosilicon chemistry with the Si–O–Si linkage. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H(OSiH2)nOH and (OSiH2)n.Foreign body granuloma: (ILDS L92.300)Emulsion polymerization: Emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomer, and surfactant. The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.Moisture cure polyurethane: Moisture-cure polyurethanes or polyurethane prepolymer are isocyanate-terminated prepolymers that are formulated to cure with ambient water. Cured PURs are segmented copolymer polyurethane-ureas exhibiting microphase-separated morphologies.Scleral buckle: A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break.List of soft contact lens materials: * Alphafilcon ABrittlenessRestylaneProliferative vitreoretinopathy: Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment. PVR occurs in about 8–10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment.Fusible core injection molding: Fusible core injection molding, also known as lost core injection molding, is a specialized plastic injection molding process used to mold internal cavities or undercuts that are not possible to mold with [cores. Strictly speaking the term "fusible core injection molding refers to the use of a fusible alloy] as the core material; when the core material is made from a [[soluble plastic the process is known as soluble core injection molding.Francis George Atkinson: Francis George Atkinson (1874 – 6 December 1902) was the first district officer in Jesselton at British North Borneo.Congenital lacrimal duct obstructionAlta Eficacia MethodIntraocular lens power calculation: The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the surgeon determines the IOL power.Pulmonary artery sling: Pulmonary artery sling is a rare condition in which the left pulmonary artery anomalously originates from a normally positioned right pulmonary artery. The left pulmonary artery then progresses posteriorly over the right main bronchus near its origin from the trachea, traverses between the trachea and the esophagus and enters the left hilum.Surface modification of biomaterials with proteins: Biomaterials are materials that are used in contact with biological systems. Biocompatibility and applicability of surface modification with current uses of metallic, polymeric and ceramic biomaterials allow alteration of properties to enhance performance in a biological environment while retaining bulk properties of the desired device.DacryocystorhinostomyAdvanced Medical OpticsOphthalmic Viscosurgical Device: Ophthalmic Viscosurgical Device (OVD) is viscoelastic solution used in eye surgery also referred to as viscoelastic agents. Their introduction has had a profound influence on the evolution of extracapsular and phacoemulsification surgery, and their use has decreased the incidence of corneal edema as aSodium polyacrylateNasolacrimal duct: The nasolacrimal duct (sometimes called the tear duct) carries tears from the lacrimal sac into the nasal cavity. The opening of the nasolacrimal duct into the inferior nasal meatus is partially covered by a mucosal fold (valve of Hasner or plica lacrimalis).Lacrimal caruncle: The caruncula lacrimalis, or lacrimal caruncle, is the small, pink, globular nodule at the inner corner (the medial angle) of the eye. It is made of skin covering sebaceous (oil) and sudoriferous (sweat) glands.Vitreous membrane: The vitreous membrane (or hyaloid membrane or vitreous cortex) is a layer of collagen separating the vitreous humour from the rest of the eye. At least two parts have been identified anatomically.John C. Snidecor: John Clifton Snidecor (October 18, 1907 - December 14, 1983) was an American professor and educator. He joined the faculty at Santa Barbara College of the University of California (now UCSB) in 1940 and served as acting provost of from February to June 1956.
