Dietary supplements contaminated, may cause blindness
August 1st 2005Minneapolis, MN—Two "all natural" dietary supplements sold as a possible treatment for cataracts and allergy symptoms are not sterile and could be contaminated with bacteria that can cause serious injury when applied to the eyes—including blindness— warn the FDA and manufacturer.
Eyetech confident about future of aptamers
August 1st 2005New York—Eyetech Pharmaceuticals reassured investors in late June that pegaptanib sodium injection (Macugen), its drug for treatment of neovascular age-related macular degeneration (AMD), is a commercial success since its launch last January. The company revised its 2005 sales projections and expects the anti-VEGF aptamer to generate between $175 and $190 million—approximately $40 million more than earlier estimates.
Evolving techniques enhance results with keratoprosthesis
July 15th 2005Washington, DC—Accruing experience with the AlphaCor (Argus Biomedical) synthetic keratoprosthesis has led to the identification of risk factors for complications along with the development of protective procedures that are enabling better outcomes, said R. Doyle Stulting, MD, PhD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Office-based surgery feasible for phakic IOL implantation
July 15th 2005Washington, DC—Refractive surgeons performing phakic IOL implantation with the iris-claw lens (Verisyse, AMO) should realize they can safely offer that procedure in their office-based surgery facility without obtaining formal certification from an ambulatory surgery accrediting organization, said Brian S. Boxer Wachler, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Topography-guided therapy best for irregular corneas
July 15th 2005Washington, DC—Topography-guided ablation (T-CAT) using the Allegretto Wave Eye-Q excimer laser (WaveLight Laser Technologie AG) offers a safe and effective primary or secondary treatment method for achieving excellent outcomes in challenging cases, said Paul H. Hughes, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Apodized diffractive lens yields excellent vision in RLE
July 15th 2005Washington, DC—Refractive lens exchange (RLE) with implantation of the AcrySof SA60D3 ReSTOR IOL (Alcon Laboratories) appears to approach the ideal refractive surgery for the presbyopic age group, said Francesco Carones, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Epi-LASIK seen as advanced surface ablation procedure
July 15th 2005Washington, DC—Results from 1 year of follow-up demonstrate that Epi-LASIK is a safe and effective alternative technique for photorefractive correction of low-to-moderate myopia and myopic astigmatism, said Vikentia J. Katsanevaki, MD, PhD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Epithelial separator demonstrates excellent performance
July 15th 2005Washington, DC—The automated, disposable Epi-K epithelial separator (Moria) safely and reliably cleaves the epithelium to create high-quality flaps and beds, and its use in Epi-LASIK is associated with favorable results with regard to postoperative pain and visual recovery profiles, said Daniela Jardim, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Customized ablation treatments produce excellent results
July 15th 2005Washington, DC—The CustomCornea (Alcon Laboratories Inc.) or CustomVue (VISX) platforms seem to offer excellent outcomes in wavefront-guided LASIK for myopia. However, induced aberration appears to be less with CustomCornea treatment, especially after nomogram adjustment for the CustomVue procedure, and that difference is apparent clinically in terms of contrast sensitivity results, according to Stephen G. Slade, MD.
Evolving techniques enhance results with keratoprosthesis
July 15th 2005Washington, DC—Accruing experience with the AlphaCor (Argus Biomedical) synthetic keratoprosthesis has led to the identification of risk factors for complications along with the development of protective procedures that are enabling better outcomes, said R. Doyle Stulting, MD, PhD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Wavefront-optimized LASIK comparable to wavefront-guided
July 15th 2005Washington, DC—The initial results of a study of the MEL-80 excimer laser (Carl Zeiss Meditec) indicate that the laser has an excellent safety and efficacy profile when performing LASIK for myopia. The patients recovered their visual function rapidly, and the uncorrected visual acuity (UCVA) levels in this trial in which wavefront-guided ablation was not performed were comparable to studies in which wavefront-guided ablation was performed using other lasers.
Additional mechanism of action possible in accommodative lens
July 15th 2005Washington, DC—The crystalens (eyeonics), an accommodating IOL approved for use in cataract patients, provides distance, intermediate, and near vision 3 years after implantation that are slightly better than the 1-year results. Optical tilt or optic flexure with induced astigmatism in conjunction with the traditional mechanism of action is hypothesized to play a role in the near visual acuity, according to Steven J. Dell, MD, speaking at the American Society of Cataract and Refractive Surgery (ASCRS) annual meeting.
Finding the best technique for wavefront-guided LASIK
July 15th 2005Washington, DC—Early outcomes after wavefront-guided LASIK may be better when using the femtosecond laser microkeratome (IntraLase Corp.) for flap creation compared with mechanical microkeratomes, but show no difference whether the procedure is performed in a single session or with a staged approach regardless of the microkeratome used.
Novel IOL changes shape to achieve accommodation
July 15th 2005Washington, DC—A novel IOL in development from PowerVision may represent the most promising concept yet for an accommodative implant, said Louis D. "Skip" Nichamin, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Evolution in CK technique revolutionizes outcomes
July 15th 2005Washington, DC—Use of the neutral-pressure "Light Touch" technique for conductive keratoplasty (CK, Refractec) improves predictability, minimizes induced astigmatism, affords faster visual recovery, and provides the opportunity for higher corrections compared with the original approach.
Fibrin tissue adhesive has benefits in pterygium surgery
July 15th 2005Washington, DC—Fibrin tissue adhesive (Tisseel VH Fibrin Sealant, Baxter BioSurgery) is a viable and attractive alternative to suturing in pterygium surgery with conjunctival-limbal autograft, said John A. Hovanesian, MD, at the World Cornea Congress V.
