As many as 10 million people around the world suffer from cataracts.

Waterford City, Ireland, October 26, 2009 -- Results of an important new study show that implantation of blue light-filtering intraocular lens (IOLs) at the time of cataract surgery increases a nu
Scientists have found that laser therapy is equivalent to two different dosages of corticosteroid medications for treating vision loss from the blockage of small veins in the back of the eye, a condition known as branch retinal vein occlusion (BRVO). Furthermore, laser treatment was shown to have fewer complications for patients.
Injecting the eye with the corticosteroid triamcinolone appears effective in improving the vision of some patients with retinal vein occlusion, an important cause of vision loss that results from blockages in the blood vessels in the retina, according to two reports in the September issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
SAN FRANCISCO, CA---This month's Ophthalmology, the journal of the American Academy of Ophthalmology, reports on use of bevacizumab (Avastin), to benefit diabetic patients with macular edema as well as people who develop cystoid macular edema after cataract surgery. Bevacizumab is also used to treat some cancers.

SAN FRANCISCO, CA--- The June issue of Ophthalmology, the journal of the American Academy of Ophthalmology, includes new insights on why some corneal transplants fail, why some patients skip their glaucoma medications, and why preventing infections after LASIK is a growing concern.
Use of the medication tamsulosin to treat male urination difficulties within two weeks of cataract surgery is associated with an increased risk of serious postoperative ophthalmic adverse events such as retinal detachment or lost lens, according to a study in the May 20 issue of JAMA.
Outpatient surgery visits accounted for about half of all surgery visits in 1996 but nearly two thirds of all surgery visits in 2006.
People who need cataract surgery, but don't like the prospect of having their eyes sutured, may be in for some good news: A team of researchers has developed a novel, adhesive hydrogel that can be painted over incisions from cataract surgery and offers the potential for faster, improved repair, they say. The hydrogel may help avoid complications associated with sutures -- the most common repair method for those types of incisions -- or unsutured incisions that are left to heal on their own, another repair method of cataract surgery.
The Food and Drug Administration (FDA) has approved a plastic lens that is permanently implanted into the eye to correct moderate to severe nearsightedness. The lens, called an intraocular lens (IOL), is similar to the type of lens implanted in the eye to restore vision following cataract surgery. Manufactured by Ophtec USA Inc., of Boca Raton, Fla., the new lens is intended to reduce or eliminate nearsightedness in adults, and will offer people another alternative to glasses, contact lenses and laser surgery such as LASIK.
For most people, the need to wear eyeglasses to read is an inevitable part of aging. The eye's natural lens hardens and loses its ability to change shape, making it more difficult to focus, especially when reading up close. With age also comes the development of cataracts or clouding of the eye's natural lens. Intraocular lenses (IOLs) traditionally have been used to replace the eye's natural lens after its removal during cataract surgery. However, with the traditional IOLs, most patients still needed to wear glasses for reading and using the computer. This, however, may be changing.
