Am J Ophthalmol. 2008 Aug 22; Authors: Bahar I, Kaiserman I, Srinivasan S, Ya-Ping J, Slomovic AR, Rootman DS PURPOSE: To compare the visual outcomes following deep anterior lamellar keratoplasty (DALK), penetrating keratoplasty (PK), and manual top-hat PK (TH-PK) in subjects undergoing corneal transplantation for keratoconus (KC). DESIGN: A retrospective...http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?tmpl=NoSidebarfile&db=PubMed&cmd=Ret... video report single incision wagon wheel phaco- August 22, 2008 Soft-to-semisoft cataracts may be challenging to remove with conventional sculpting and chopping phaco techniques. There are risks to intracameral structures during excessive and prolonged instrumentation. At a paracentesis site, corneal trauma may lead to wound leakage and astigmatism. We describe a technique for soft-to-semisoft lens extraction that minimises the mechanical stresses within the eye and utilises low phaco energy during surgery. The endonucleus is positioned in the vertical...http://bjo.bmj.com/cgi/reprint/92/9/1205?rss=1 Refractive errors significantly affect adults in united states- August 13, 2008 Approximately half of all adults in the United States aged 20 and older have refraction errors in their eyes that result in less than 2020 vision, according to an article released on August 11, 2008 in the Archives of Ophthalmology, one of the JAMAArchives journals. When the eye does not properly focus light on the retina, it results in nearsightedness, farsightedness, or astigmatism.

Epidemiology: prevalence of refractive error in the united states, 1999-2004- August 11, 2008 Objective To describe the prevalence of refractive error in the United States. Methods The 1999-2004 National Health and Nutrition Examination Survey (NHANES) used an autorefractor to obtain refractive error data on a nationally representative sample of the US noninstitutionalized, civilian population 12 years and older. Using data from the eye with a greater absolute spherical equivalent (SphEq) value, we defined clinically important refractive error as follows: hyperopia, SphEq...http://archopht.ama-assn.org/cgi/content/short/126/8/1111?rss=1 Clinical sciences: a comparison of customcornea myopia algorithms for wavefront-guided laser in situ keratomileusis- August 11, 2008 Objective To determine whether the new CustomCornea M3 (myopic astigmatism) algorithm places additional pulses in the periphery to counter excimer laser peripheral ablation inefficiency. Methods Analysis of 25 myopic eyes of 18 patients that were within the approved indications for both the myopic astigmatism (M3) and myopic sphere (A7) algorithms. We analyzed ablation depth at peak and 4-mm, 6-mm, and 7-mm zone diameters for both the A7 and M3 algorithms. Results The M3...http://archopht.ama-assn.org/cgi/content/short/126/8/1067?rss=1 Surgically induced astigmatism after biaxial phacoemulsification compared to coaxial phacoemulsification- August 8, 2008 Surgically induced astigmatism after biaxial phacoemulsification compared to coaxial phacoemulsification Eye advance online publication, August 8, 2008. doi:10.1038eye.2008.242 Authors: R Morcillo-Laiz, M A Zato, F J Munoz-Negrete & F Arnalich (Source: Eye) MedWorm Sponsored Message: Find out how you can get your message across here by sponsoring this MedWorm news feed.http://dx.doi.org/10.1038/eye.2008.242 |
