| Potential new post-laser refractive surgery complication identified
A new syndrome characterized by noninflammatory corneal opacification can occur in some patients within 9 days after undergoing LASIK or PRK, according to a study. The opacification gradually clears over several months and can also cause a possible hyperopic shift in refraction, the study authors said. Baris Sonmez, MD, and Robert K. Maloney, MD, identified 23 eyes of 14 patients with the syndrome, which they termed central toxic keratopathy. Four eyes had undergone PRK and 19 eyes had undergone LASIK. In all cases, eyes developed central corneal opacification in the laser-treated area 3 to 9 days after surgery, which persisted for 2 to 18 months, the authors reported. Eighteen of the 19 LASIK-treated eyes developed diffuse lamellar keratitis before the onset of the opacification, they noted.

Is my child old enough to wear contact lenses?
The most common questions that eyecare professionals hear from parents is: At what age can children start wearing contact lenses? Is my child mature enough to wear contact lenses? A new research has showed that children of 8 to 12 can easily handle the responsibility of contact lenses just as well as their older peers. In the study, children and teenagers reported that it was much easier to engage in sports, dancing and other activities while wearing contact lenses. .
Not quite, Mr. McCain
Lose those rose-colored glasses, John McCain, at least if you're serious about impressing the American public with your credentials to be president. Myopia is profoundly disappointing on the part of someone who once built a national reputation on brutal honesty. Here's Mr. McCain, back from a trip to a Baghdad market on Sunday that required precautions fit for, well, war. Bulletproof vests for Mr. McCain and his delegation, helicopter cover above and Humvees on the ground. Mr. McCain's message? We're apparently not getting the full picture, or the whole truth, about the Iraq war and the progress that's being made -- thanks to a media that won't function the way the Republican senator from Arizona would prefer. Sounds like the White House line, only from a once-heralded figure in that very same media seven years ago -- when he was the only thing between George W.
Zinc link to leading cause of blindness macular degeneration
An international research team led by scientists at the Institute of Ophthalmology, UCL (University College London), has found high levels of zinc in the deposits in the eye which are a marker of age-related macular degeneration (AMD), the leading cause of blindness in the elderly in the developed world. The finding, published in the latest edition of Experimental Eye Research, contributes to a better understanding of AMD and could influence the development of effective treatments. AMD is a form of macular disease which affects the eye's retina. An estimated half a million people in the UK have it, and 40 per cent of these are over 75. Despite the potentially devastating impact on patients quality of life, no successful therapy to stop or reverse the progression of AMD is available in the majority of cases.
