Non-surgical corneal reshaping, also known as orthokeratology, has been available since the 1960’s. Early lenses were made from . polymethyl. methacrylate (PMMA), a hard plastic with low oxygen permeability or an early gas permeable material. While practiced on a limited basis until the 1980’s, orthokeratology declined in popularity because of limited lens designs and variable refractive results. Materials used to manufacture contact lenses and the introduction of computer lathes that can create sophisticated contact lens shapes have renewed interest in corneal reshaping. These key features along with an increase in oxygen permeability, allow for the manufacturing of reverse geometry designs and the ability to wear these lenses overnight. Modern orthokeratology designs . 1065 Sadder, but TEN D E D AB ST R ACT Intertemporal choices, which require a decision between a sooner (usually smaller) reward and a later (usually larger) reward, are pervasive in daily life and Corrective lenses Glasses Short-sightedness can usually be corrected using glasses that are made specifically to your _______________(2).

Two leading researchers who are also practitioners in the field of controlling short-sightedness review the evidence available from various clinical studies which have assessed how effective Overnight Vision Correction (OVC) is in slowing down or halting the progression short-sightedness in children. They highlight the positive conclusions reached by the studies and provide their views on the clinical reasons why overnight .

"The excavation of the disc in glaucoma is not a purely mechanical result of exalted pressure; it is, in part at least, an atrophic condition which, though primarily due to pressure, includes vascular changes and impaired nutrition of the substance of the optic disc which may possibly progress even though all excessive pressure be removed.".
