Ambulatory center payments urged to match hospital costs
February 15th 2004Washington, DC-The Medicare Payment Assessment Commission (MedPAC) will recommend that Congress revise the payment system for ambulatory surgery centers (ASCs) so it falls in line with payments for similar procedures performed at a hospital.
Phakic IOL delivers good results in FDA trial for myopia
February 1st 2004Anaheim, CA-An increasing number of IOLs are being developed to achieve improved vision in patients with extreme levels of myopia. One such lens is the Artisan/ Verisyse phakic IOL (Ophtec USA/Advanced Medical Optics), said R. Doyle Stulting, MD, PhD, who reported the results of the FDA clinical study here at the American Academy of Ophthalmology annual meeting.
Accommodating IOL a welcome entity for refractive surgeons
February 1st 2004Anaheim, CA-The recently approved model AT-45 accommodative IOL (Crystalens, eyeonics inc. [formerly C&C Vision]) is expected to be a very useful practice addition for surgeons in their management of presby-opia, said D. Michael Colvard, MD, at the International Society of Refractive Surgery/ American Academy of Oph-thalmology subspecialty day meeting.
Blue light-filtering IOL option for cataract surgery
February 1st 2004Anaheim, CA-Although longer follow-up is needed to determine whether the pseu-dophakic, blue light-filter-ing IOL (AcrySof Natural, Alcon) reduces the risk of progression of age-related macular degeneration (AMD), available indirect evidence provides sufficient sup-port to advocate its use in cataract surgery, said Robert J. Cionni, MD.
Syringe-style unfolder allows safe, simple IOL implantation
February 1st 2004Kansas City, KS-The new Emerald-Ease Simple Syringe Unfolder (AMO) offers cataract surgeons another alternative for implanting the AR-40E IOL (Sensar with Opti- Edge, AMO) through an unenlarged phaco incision, said John D. Hunkeler, MD.
Prospective study confirms contrast sensitivity benefits of IOL
February 1st 2004Eugene, OR-Implantation of the anterior surface modified prolate IOL (Tecnis, Pfizer Ophthalmics) results in improved functional vision for cataract surgery patients compared with a standard spherical IOL, said Mark D. Packer, MD.
Patients enjoy near-vision plus of pseudoaccommodative IOL
February 1st 2004Munich, Germany-The AcrySof ReSTOR pseudoaccommodative IOL (Alcon) with its apodized diffractive optic provides patients with excellent near visual acuity without compromising distance vision, signifi- cantly reducing contrast sensitivity, or increasing the incidence of severe visual disturbances compared with monofocal con- trols, said James A. Davison, MD, FACS, at the XXI Congress of the European Society of Cataract and Refractive Surgeons here.
Refractive lens exchange: A concept whose time has come
February 1st 2004Anaheim, CA-Refractive lens exchange (RLE) will become the dominant refractive procedure for treating hyperopia and myopia, as well as presbyopia, according to cataract/refractive specialist I. Howard Fine, MD, who spoke during the American Academy of Ophthalmology's refractive subspecialty day meeting.
Microbial keratitis after LASIK enhancement poses risk
February 1st 2004Daniel H. Chang, MD, received his BS degree in chemistry with honors from the California Institute of Technology, where his investigational career began with a summer undergraduate research fellowship. He obtained his MD degree from Duke University, where he served as a research analyst. Dr. Chang is currently chief resident in ophthalmology at Emory University and will pursue a fellowship in cornea and external disease next year. Dr. Chang's research activities have included investigations of the free electron laser and corneal transplantation.
LASIK with wide ablation safe, effective for myopia
February 1st 2004Kansas City, KS-LASIK using the S3 Variable Spot Scanning (VSS) excimer laser with ActiveTrack (VISX) to create an 8-mm ablation diameter effectively, predictably, and safely treats myopia and myopic astigmatism in patients with large scotopic pupils, according to the interim results of a prospective study reported by John F. Doane, MD, FACS.
Larger optical zone minimizes higher-order aberrations
February 1st 2004New York-The software adjustability of optical zone size with the LADARVision 4000 excimer laser (Alcon) provides a benefit for treating patients with large entrance pupil sizes because it is likely to minimize total higher-order aberrations after LASIK, said Barrie D. Soloway, MD.
Different aberrometry technologies not always comparable
February 1st 2004Houston-Results from a clinical practice study directly comparing wavefront analysis using two different technologies-ray tracing (Visual Function Analyzer version 1.1,VFA, Tracey Technologies) and a Hartmann-Shack-type aberrometer (WaveScan Version 3.01, VISX)-show that the machines are in good agreement in their measurements of refraction and root mean square (RMS) values for both lower-order and total aberrations, but not in their measurement of higher-order aberrations, according to Rahul T. Pandit, MD.
Surgeons set sights on agenda of Current Concepts meeting
February 1st 2004Dorado, Puerto Rico-The 26th annual "Current Concepts in Ophthalmology" meeting, sponsored by Johns Hopkins University School of Medicine/Wilmer Eye Institute and supported by Ophthalmology Times, will be held Feb. 20 to 23 at the Hyatt Dorado Beach Resort.
