Astigmatism News and Research

RSS

Astigmatism is a type of refractive inaccuracy in which the shape of the normally curved surface of the cornea is curved to different degrees in different areas. As a result of this abnormality, the light rays that enter the eye fails to converge at a focal point and instead comes to a focus at different focal points with a distance between them.

Columbia researchers develop new non-invasive approach to permanently correct vision

Nearsightedness, or myopia, is an increasing problem around the world. There are now twice as many people in the US and Europe with this condition as there were 50 years ago. In East Asia, 70 to 90 percent of teenagers and young adults are nearsighted.

Lens doesn't compensate for astigmatic defocus of the eye, study reveals

For people with nearsightedness (myopia), the lens doesn't compensate for growth or other changes in the structure of the eye, according to a long-term follow-up study in the September issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

Leica Microsystems launches IOLcompass Pro intraocular lens positioning system

Leica Microsystems in partnership with TrueVision Systems Inc. launches the IOLcompass Pro. IOLcompass Pro is a software-based guidance system for pre-operative planning and intra-operative positioning of premium intraocular lenses (IOLs). It supports ophthalmic surgeons to achieve minimal residual astigmatism for their patients by providing stable and accurate guidance throughout the cataract surgical workflow.

Laser eye surgery: a glimpse into the future - An interview with Professor Dan Reinstein

LASIK (Laser In Situ Keratomileusis) creates a hinged flap with a microkeratome and evaporating corneal tissue under the flap with an excimer laser. However, the concept that refractive error could be corrected by sculpting corneal stromal tissue to change corneal curvature was the brainchild of Jose Ignacio Barraquer Moner in 1948.

Report describes effectiveness of new computer-based vision-screening test for kids

Many eye disorders in young children are asymptomatic and may remain undetected without testing. Since effective treatments are available for many of those conditions, early identification and intervention are critical to prevent potentially permanent vision problems.
