STAAR Surgical Co. received CE mark approval for its KS-3Ai preloaded IOL injection system with an aspheric optic design. The company will now be allowed to market this IOL for use in cataract surgery in 21 countries. STAAR will begin shipments to distributors this month.
The Centers for Medicare and Medicaid Services (CMS) added the AcrySof IQ IOL (Alcon Laboratories) to the New Technology Intraocular Lens (NTIOL) classification of Reduced Spherical Aberration. Effective May 19, ambulatory surgery centers using the AcrySof IQ IOL for cataract surgery will receive an additional $50 from Medicare. The IOL gained inclusion by proving the same or greater clinical benefit as the lens that established the NTIOL subset. The NTIOL subset and adjusted payment will remain in effect until Feb. 27, 2011.
S?o Paulo, Brazil Brazil-Deep sclerectomy is not the "holygrail" of glaucoma surgery, but available evidence indicates thatit is definitively safer than trabeculectomy, according to Tarek M.Shaarawy, MD. Deep sclerectomy can also result in long-term successrates comparable with those of trabeculectomy when performed withproper technique by experienced hands, he added.
San Francisco-The crystalens accommodating IOL (eyeonics)improved visual outcomes "dramatically" in a study of patients withhigh myopia or high hyperopia. The IOL achieved similar near visualacuity levels in both patient groups, reported Harvey Carter, MD,at the annual meeting of the American Society of Cataract andRefractive Surgery.
Compulsive graft management, questions, appropriate differentialdiagnosis are key, surgeon says
Eugene, OR-The Tecnis Z9000 modified prolate IOL (AMO)improves functional vision by eliminating positive ocular sphericalaberration, which increases by 0.15% a year, according to MarkPacker, MD, FACS.
Dorado, Puerto Rico-Physicians delving into the refractivecataract surgery arena should be careful screening and selectingpatients to ensure the best results. In order to do this, surgeonsneed to survey patients about their needs and desires pertaining totheir vision, so that the appropriate IOL technology can be chosen,explained Louis D. "Skip" Nichamin, MD, who spoke during theCurrent Concepts in Ophthalmology meeting here.
Trevor Lamb, ScD, FRS, FAA, of the John Curtin School of MedicalResearch, Australian National University, Canberra, Australia, andEdward Pugh Jr., PhD, from the F.M. Kirby Center for MolecularOphthalmology, Scheie Eye Institute, University of Pennsylvania,Philadelphia, share the 2006 Proctor Medal and Lecture for thedevelopment of a comprehensive model of photoexcitation in rodreceptors and its application to the electroretinogram (ERG). Thiswork led to the use of the ERG in the analysis of deficits in avariety of basic and clinical situations.
There are common molecular and cellular mechanisms in differenttissue types and key genes that regulate wound healing.Transforming growth factors (TGFB) and connective tissue growthfactor (CTGF) are important growth factors that interact in thesteps leading to scarring, according to George Schultz, PhD, whospoke at the annual meeting of the Association for Research inVision and Ophthalmology.

Transforming growth factor B3 (TGFB3) is instrumental in woundhealing without scar formation. Mark Ferguson, PhD, described aseminal discovery that wounds made in embryos?which have highlevels of TGFB3 and low levels of TGFB1 andTGFB2?heal scar-free.

New York?The Scleral Spacing Procedure (SSP) for Presbyopia with PresVIEW Scleral Implants (PSI) (Refocus Group Inc., formerly PresbyCorp) provides significant improvement in near visual acuity (VA) and no change in the uncorrected distance VA, according to Barrie D. Soloway, MD, FACS.
Atlanta?A 6-year study confirms the safety of dual-laser blepharoplasty for aesthetic rejuvenation of the upper and lower eyelids. Describing a series of 320 blepharoplasties, Harley Freiberger, MD, a dermatologic cosmetic surgeon in Los Angeles, reported that no permanent complications were observed, and that lesions healed rapidly and patients were quickly able to return to normal activity.
Memphis, TN?Twenty-five-gauge vitrectomy has become his preferred method for most vitrectomy applications, according to Steven T. Charles, MD, who described how he uses this new technology.
Frankfurt, Germany?Twenty-three gauge vitrectomy instrumentation has become available and offers surgeons an alternative to 25-gauge instruments. Claus Eckardt, MD, looked at the pros and cons of these smaller instruments.
Cleveland?Gene therapy and pharmacologic therapy, administered separately and combined, rescued retinal function in blind mice that were bred without an enzyme crucial to the detection of light.
Des Plaines, IL?Addition Technology announces its fourth-quarter 2005 sales of Intacs corneal implants increased 29% over the same quarter the prior year and 12% over third-quarter 2005.
Glendora, CA?OASIS Medical filed a lawsuit against Johnson & Johnson/Johnson & Johnson Vision Care Inc.
