New York-Standard textbook descriptions about early detection of glaucoma underestimate the prevalence of glaucoma, said Robert N. Weinreb, MD.

New York-Glaucoma specialists considering the future of the disease and its prevention and treatment should look to cardiovascular disease as a model, attendees at "Glaucoma 2004: Mastering Tools and Techniques for the 21st Century" here were told.

Ormond Beach, FL-The Costa Del Mar 2004 Dealer Catalog was picked for a Gold ADDY award at the American Advertising Federation's annual ADDY awards event.

San Diego-Presence of the blue light-filtering pseudophakic IOL (AcrySof Natural, Alcon) has no adverse effect on the surgeon's ability to perform vitreoretinal procedures following cataract extraction and IOL implantation, said David L. Parver, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery

The new Restor IOL (Alcon, Fort Worth, TX), a single-piece refractive/diffractive implant, achieved good uncorrected distance and near visual acuity levels in a trial of initial results. There were few complaints of unwanted visual images.

San Diego-The AcrySof Natural IOL (SA60AT, Alcon Laboratories, Fort Worth, TX) that filters blue light does not negatively affect patients’ color perception. The IOL more closely mimics the human crystalline lens and scotopic vision is excellent in these patients, Robert Cionni, MD, stated..

San Diego-Blocking light from the blue portion of the spectrum is thought to be advantageous to the eye, and IOL manufacturers have developed IOLs with this feature. However, aging eyes may be negatively affected by filtering out blue light, according to Randall J. Olson, MD

San Diego-High speed video photography and 2-dimensional laser visualization have helped researchers better understand the dynamic characteristics of the fluid pulses from the AquaLase liquefaction device (Alcon Laboratories). This information is beneficial for surgeons as they develop and refine their cataract removal technique using this new technology, said Ramon C. Dimalanta, PhD, at the annual meeting of the American Society of Cataract and Refractive Surgery.

San Diego - The AcrySof Toric IOL (Alcon Laboratories, Fort Worth, TX) is outperforming a comparable spherical IOL in uncorrected visual acuity (UCVA) levels and the low level of residual astigmatism. The interim safety and efficacy results of the FDA clinical trial of the AcrySof Toric IOL were presented here at the annual meeting of the American Society of Cataract and Refractive Surgery.

San Diego - Bimanual microincision phacoemulsification with the Millennium System (Bausch & Lomb) is safe and associated with excellent visual acuity results, said Mark Packer, MD, at the American Society of Cataract and Refractive Surgery annual meeting.

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.

San Diego-A newly identified biomicroscopic sign, the sharkfin sign, seems to indicate that focal thermal damage to the stroma has occurred during phacoemulsification. The sharkfin sign seems to be a curvilinear lucency in the corneal incision.

San Diego-Now that capsular tension rings (CTRs) from both AMO/Ophtec and Morcher have been approved, surgeons need to know which eyes can best benefit and which eyes should not receive CTRs.

San Diego-Experiments in model eyes that examined the patterns of light transmittance and image quality point out the differences in how various multifocal IOLs work and how some designs may have advantages over others.

San Diego - Despite the doubts of some investigators, cavitation is a real, measurable phenomenon in phacoemulsification with the Sovereign phaco instrument (AMO, Santa Ana, CA), according to Mark E. Schafer, PhD.
