South San Francisco, CA-An ongoing study of ranibizumab (Lucentis, Genentech) has found a higher incidence of stroke in patients with neovascular (wet) age-related macular degeneration who were administered a 0.5-mg dose intravitreally compared with patients who were given a 0.3-mg dose intravitreally (1.2% versus 0.3%, respectively; p = 0.02).

Jeddah, Saudi Arabia-Multizone LASIK with peripheral near zone ablation to correct presbyopia together with myopia or hyperopia is safe, effectively corrects spherical error, and improves near vision but without offering a high rate of spectacle independence, according to a study from refractive surgeons here at the Magrabi Hospital.

Las Vegas-Ophthalmologists can use one of several modified strategies to perform cataract surgery in patients who are taking or have taken tamsulosin (Flomax, Boehringer Ingelheim Pharmaceuticals), with good outcomes and low complication rates, when they know of the medication history in advance, David F. Chang, MD, told those attending the annual meeting of the American Academy of Ophthalmology here.

Las Vegas-Studies have found conflicting evidence that sleep apnea is a risk factor for glaucoma, with variable control groups and variability in defining sleep apnea and glaucoma contributing to the disagreement. Parag A. Gokhale, MD, speaking here at the annual meeting of the American Academy of Ophthalmology, said he sides with those who believe that a positive association exists between the two conditions.

Sacramento, CA-Dilation of Schlemm's canal to 360? and use of a tension suture result in significantly decreased postoperative IOP levels, said Richard A. Lewis, MD, who is in private practice here. The procedure, canaloplasty, safely enhances aqueous outflow in patients with primary open-angle glaucoma (POAG), said Dr. Lewis, reporting the findings of an ongoing prospective multi-site study being conducted in the United States, the European Union, and South Africa.

Jeddah, Saudi Arabia-Multizone LASIK with peripheral near zone ablation to correct presbyopia together with myopia or hyperopia is safe, effectively corrects spherical error, and improves near vision but without offering a high rate of spectacle independence, according to a study from refractive surgeons here at the Magrabi Hospital.

Las Vegas-Marcelo V. Netto, MD, was presented with the 16th annual Troutman Award at the annual meeting of the American Academy of Ophthalmology. He received the award as lead author of a paper that described the findings from wavefront analysis in a population of normal refractive surgery patients [Netto MV, et al. J Refract Surg. 2005;21:332-338].

Stanford, CA-Refractive surgeons performing conductive keratoplasty (CK, Refractec) for correction of mild to moderate hyperopia can expect good visual results initially, but they should warn patients that CK effects might not be permanent, explained Jason S. Ehrlich, MD, PhD.

New York-The idea of using selective laser trabeculoplasty (SLT) for steroid-induced glaucoma originated with a patient's stubborn resistance to surgery, according to Janet P. Serle, MD.

Santiago, Chile-Torsional phacoemulsification seems to be an improvement over standard phacoemulsification because of lower amounts of turbulence, less repulsion of the nuclear fragments, and a different pattern of cavitation due to a 90? shift in the delivery of the ultrasonic power, according to Jaime Zacharias, MD.

Investigators are eagerly comparing ways to perform phacoemulsification to obtain the best results for patients. Bimanual microincision phaco has been receiving a great deal of attention and is being compared with ultra-small-incision coaxial phaco and with conventional phaco.

Las Vegas-Laboratory experiments involving an overpressurization technique have demonstrated that acoustic transient cavitation is necessary to produce efficient phacoemulsification, according to Mark E. Schafer, PhD, speaking here at the annual meeting of the American Academy of Ophthalmology (AAO).

Holland, MD, FRCSC, said at the annual meeting of the American Academy of Ophthalmology here.

Charleston, SC-A large study of routine phacoemulsification found the total incidence of intraoperative floppy iris syndrome (IFIS) to be 3.8%.
