San Diego-Phakic anterior chamber IOLs affect the biometric measurement of axial length, which results in clinically significant errors in IOL power calculations in patients who need to undergo cataract surgery. Gerald Zaidman, MD, described such a patient and offered suggestions for managing this complicated problem here at the American Society of Cataract and Refractive Surgery.
Rochester, NY-Bausch & Lomb and CIBA Vision Corp. have settled longstanding patent infringement lawsuits related to silicone hydrogel contact lens materials used to make their extended-wear lenses.
Fort Lauderdale, FL-Initial clinical trial experience suggests that CO2 laser-assisted nonpenetrating deep scle- rectomy (NPDS) holds promise as an excellent option for glaucoma therapy, said Ehud I. Assia, MD, at the annual meeting of the Association for Research in Vision and Ophthalmology.
Fort Lauderdale, FL-In a comparison study that has implications for wound healing in surface ablation procedures, investigators found that four commonly used topical ophthalmic antibiotics-moxifloxacin (Vigamox, Alcon), levofloxacin (Quixin, Santen), gatifloxacin (Zymar, Allergan), and ofloxacin (Ocuflox, Allergan)-all showed evidence of toxicity on human corneal epithelial cells, with moxifloxacin causing the least amount of toxicity.
Santa Ana, CA-Advanced Medical Optics Inc. (AMO) is offering an extended low-diopter and plano range of its Array silicone IOL.
Half of cataract surgeons only wait 2 weeks between the time of the first and second eye surgery.
San Diego - Two-year follow-up of eyes with the ClariFlex with OptiEdge silicone IOL (AMO) implanted show that the second-generation silicone IOL with its novel edge design is performing well. Furthermore, risk of posterior capsular opacification (PCO) and glare was minimal, according to the results of a study presented by Elizabeth A. Davis, MD, FACS, at the annual meeting of the American Society of Cataract and Refractive Surgery.
PJD is a relatively quick procedure that uses a blunt-tipped cannula inserted between the bulbar conjunctiva and the sclera.

Researchers around the world have been working diligently over the last 25 years to develop artificial corneas for patients who are not good candidates for the current techniques of keratoplasty, according to Eduardo C. Alfonso, MD.
More than 330 ophthalmologists from 24 states and several countriesattended "Glaucoma 2004: Mastering Tools and Techniques for the 21stCentury," on Friday, June 4, and Saturday, June 5, at the Plaza Hotel.
The use of antiproliferative agents has helped increase thelikelihood of successful filtering surgery by inhibiting the wound healingresponse. The problem is that these agents also contribute to the risk ofbleb leak and bleb-associated infection, reported Paul J. Lama, MD, of theUniversity of Medicine and Dentistry of New Jersey, Newark, and the Veterans'Administration Medical Center, East Orange, NJ.
San Diego-The key to achieving the most from refractive surgery is an understanding of the biomechanics of the refractive procedures in the eye coupled with advances in pharmaceuticals to facilitate wound healing.
Baltimore-Peripheral iris fixation of a foldable posterior chamber IOL using a modified McCannel suture appears to be a useful technique for the management of delayed-onset within-the-bag IOL subluxation in eyes with pseudoexfoliation syndrome, said Aruoriwo M. Oboh-Weilke, MD
Optical complications were substantial glare in about 20% of patients, halos in 30%, and problems with night driving in 20%.

Dorado, Puerto Rico-After positive results from a European clinical trial showed transforming growth factor-b2 (TGF-b2) mono clonal antibody was effective in delaying wound healing after first-time trabeculectomy, U.S. investigators are undertaking a multicenter clinical trial to compare the new agent with 5-fluorouracil (5-FU), reported Marshall N. Cyrlin, MD.
