Check out several recent items in the contact lens news section, including an announcement regarding availability of the new Acuvue Oasys for Presbyopia contact lens.
All About Vision has appointed nationally recognized cataract and refractive surgeon Robert L. Epstein, MD, to its Editorial Advisory Board.
As one of the first surgeons in the United States to perform LASIK, Dr. Epstein brings a wealth of expertise to the task of ensuring that All About Vision educates consumers with accurate, comprehensive information.
Dr. Epstein is medical director and chief surgeon at Mercy Center for Corrective Eye Surgery in Chicago and has regularly performed LASIK, PRK, epi-LASIK, Crystalens implantation and other procedures. He helped develop multifocal LASIK and has been awarded several patents, including one for a device that increases the safety and accuracy of laser vision correction.
Presbyopia causes near vision focusing problems beginning at around age 40.
If you need cataract surgery, you also may want your presbyopia corrected so that you can see at multiple distances.
Crystalens and accommodating IOLs potentially can provide focus at all distances by shifting with the movement of eye muscles. Multifocal IOLs have different zones, which provide vision at near, intermediate and far ranges.
All About Vision served more than 2.3 million unique visitors (measured weekly) in the first quarter of 2009, up about 20% from the same period in 2008.
Google generated 67% of site visitors, which originated in 230 countries, although 84% of visits were from the U.S. and Canada.
A total of 10,823 websites sent traffic to All About Vision during this period, including Wikipedia, Gunnar Optiks, Facebook, iVillage and Slate.
All About Vision recently posted two news items that explain more about what causes these diseases.
Low cerebrospinal fluid appears to be present in both Alzheimer’s and glaucoma. Investigations into abnormal presence of serum cystatin C (a marker for kidney disease) also have shown that chronic kidney disease and macular degeneration sometimes occur together.
A chalazion looks very similar to a stye, but may not go away unless it is cut open and drained.
While 20/20 vision is a familiar term for good vision, many people don’t understand how eye charts are used to measure eyesight during routine eye exams.
