Researchers develop photochromic lenses

In Singapore researchers have developed UV-responsive, or lenses that darken when exposed to ultraviolet light, protecting the eyes against the sun’s damaging rays. The lenses contain a novel polymer laced with an intricate network of nano-sized tunnels filled with dyes. The investigators hope to have these photochromic contact lenses commercially available within a year.

LASIK and patient satisfaction

LASIK (laser assisted intrastromal keratomileusis) or Laser Vision Correction is a very popular surgery to reduce the dependence on vision correction devices (glasses or contact lenses). The Storm Eye Institute did a comprehensive search of the worldwide clinical literature and identified 19 peer-reviewed studies. The studies covered the period of 1995 (first approved in the […]

FDA Approval of Eye Implant to Treat Macular Edema

Allergan, Inc. announced that the Food and Drug Administration approved the sale of its eye implant Ozurdex, intended to treat the vision disorder macular edema (swelling in the macula-area of retina responsible for quality vision) following blockage of retinal veins. The device is a biodegradable implant that is injected into the eye releasing a cortical […]

Contact lenses coated in stem cells may restore sight to patients with corneal disease

Researchers from Australia’s University of New South Wales have used contact lenses coated in stem cells to restore sight to patients suffering from corneal disease. In the procedure, the investigators removed tissue with regenerative stem cells from patients own eyes and then multiplied them in the laboratory on the surface of a contact lens. Next, […]

Device would allow visually impaired to access Internet thru telephone voice commands

Audiopoint (automatic speech recognition software business in Rockville, MD) has developed a system that would enable the visually impaired to surf the web as quick as everyone else. The company developed the Voice Terminal Service (VTS) to fully access the Internet through voice commands via any type of telephone.

Researchers say that they have stimulated growth of retinal cells in mice

As reported in the November edition of the Proceedings of the National Academy of Sciences, “cells in the retina of mice can be coaxed to create new neurons following injury”. The implication for this technology is exciting since the possibility of “regenerating” vision after damage is soon to be a reality.
