AAO Podcast coverage from Day 1 in Atlanta
November 7th 2008In this podcast, John F. Doane, MD, FACS, discusses addressing presbyopia with accommodating IOLs, and Scott W. Cousins, MD, talks about the role of injury and inflammation in the pathogenesis of dry age-related macular degeneration (AMD). Also Scott M. MacRae, MD, relays the current limitations of laser vision correction, and Paul Sternberg Jr., MD, speaks about new approaches to the treatment of dry AMD.
Honed communication skills key in handling dissatisfied patients
November 7th 2008Skillful physician-patient communication is paramount to successful prevention and management of dissatisfied LASIK patients, said Jennifer Morse, MD, assistant clinical professor of psychiatry, University of California San Diego.
Factors associated with changes in night-driving visual performance evaluated
November 7th 2008Studies with a night-driving simulator (NDS) found that changes in night-driving performance were associated strongly with the type of treatment used to perform LASIK, and that wavefront-guided procedures were correlated with better performance. The study involved 59 patients (98 eyes) who were tested preoperatively and 6 months postoperatively with the NDS, set to simulate nighttime driving on a rural road at 55 miles per hour, with and without glare.
FDA initiating prospective trial of postLASIK quality of life
November 7th 2008Planning is underway for a large national prospective study to evaluate postLASIK quality-of-life outcomes in a clinical setting, said Malvina B. Eydelman, MD, director, division of ophthalmic and ear, nose, and throat devices, Center for Devices and Radiological Health (CDRH)/FDA, Rockville, MD.
Top refractive surgery pearl: Pay attention to the tear film
November 7th 2008Refractive surgeons need to remember that the tear film is the most important refracting surface of the eye, and if it is abandoned, surgical outcomes will suffer, said Eric D. Donnenfeld, MD, clinical professor of ophthalmology, New York University.
Thin corneas: Risk factor for ectasia?
November 7th 2008Scientific evidence does not support the hypothesis that thinner preoperative central corneas are an independent risk factor for postLASIK ectasia, said William B. Trattler, MD, director of cornea at the Center for Excellence in Eye Care, Miami. Eyes with a thin cornea (less than 500 µm) and normal topography are at no greater risk than those with thicker corneas of developing postoperative ectasia and may be biomechanically strong and similar to thicker corneas in their behavior, Dr. Trattler added.
Education products unveiled at AAO meeting
November 7th 2008The 2008 annual meeting of the American Academy of Ophthalmology (AAO) is featuring several new and forthcoming patient education, clinical education, and practice management products produced by the AAO to meet the educational and practice needs of its members. During the meeting, these products are available at the academy's resource center and online.
Complement C3 inhibitor is a potential treatment for AMD
November 7th 2008A cyclic 13-amino acid peptide (POT-4, Potentia Pharmaceuticals Inc.) is the first complement-binding therapy tested in humans with wet age-related macular degeneration (AMD). Philip Rosenfeld, MD, PhD, of the Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, presented results from the phase I Clinical Trial Assessment of Safety for POT-4 (ASaP) that indicate the drug appears to be safe and well tolerated and released slowly from a deposit in the vitreous cavity.
Antioxidant eye drop explored for dry AMD
November 7th 2008An antioxidant eye drop (OT-551, Othera) is being investigated to treat geographic atrophy in dry age-related macular degeneration (AMD), said Paul Sternberg, MD, from the Vanderbilt Eye Institute, Vanderbilt University School of Medicine, Nashville, TN.
C5aR inhibitor blocks complement in AMD
November 7th 2008A pepidomimetic inhibitor of the receptor for C5aR (JPE1375) blocks the mechanism that draws inflammatory cells into the disease process of age-related macular degeneration (AMD). When blocked, the numbers of neutrophils and macrophages decrease substantially, and in turn, choroidal neovascularization (CNV) also decreases, according to Anthony Adamis, MD, Department of Ophthalmology & Visual Sciences, University of Illinois.
Micro-Surgical Safety Task Force focuses on sutureless vitrectomy
November 7th 2008Twenty-five-gauge sutureless vitrectomy has been increasing in popularity. In conjunction with this surge, however, is the observation that the procedure is associated with increased postoperative complications such as hypotony, choroidal detachment, and an increased incidence of endophthalmitis. Richard Kaiser, MD, from the Retina Service of Wills Eye Institute, Philadelphia, focused on endophthalmitis and noted that the 25-gauge procedure has a risk of infection that is 12.4 times greater than the 20-gauge procedure.
Stem cells may protect retina from progressive degeneration, study says
November 3rd 2008A proprietary purified human neural stem cell product (HuCNS-SC, StemCells), when transplanted into a well-established animal model, may protect the retina from progressive degeneration, according to researchers.
Multi-component IOL offers enhanced options, accuracy
November 1st 2008The multi-component IOL (PrecisionLens) is a novel, foldable implant technology consisting of three optical elements (two exchangeable) that was created to produce an emmetropic result reliably in all patients who undergo cataract surgery or refractive lens exchange.
Newer one-piece IOL offers excellent visual acuity, says surgeon
November 1st 2008The state-of-the-art material and design of a novel one-piece IOL can offer refractive stability and predictability, according to Daniel A. Black, MBBS, FRACO, FRACS. This newer IOL rivals other more established IOLs and may soon become the gold-standard treatment in cataract procedures, he said.
2-year data promising for dual-optic lens; centers well and is easy to implant, surgeon says
November 1st 2008Two lenses may be better than one. In a prospective trial of 30 eyes, a dual-accommodating IOL, with a high-diopter anterior optic and a minus-power posterior optic, provided good distance visual acuity, depth of focus, and a good safety profile.
ESCRS Endophthalmitis Study: Intracameral cefuroxime injections prevent endophthalmitis
November 1st 2008Prophylactic intracameral cefuroxime injections prevent the development of endophthalmitis after cataract surgery, according to results of the European Society of Cataract and Refractive Surgeons Endophthalmitis Study. The finding remains controversial in the United States, where cefuroxime has not been approved by the FDA and the standard of care to prevent endophthalmitis after cataract surgery is the administration of preoperative, perioperative, and postoperative topical fluoroquinolone drops.
Severity determines intraoperative floppy iris syndrome management approach
November 1st 2008A cataract surgeon who first identified intraoperative floppy iris syndrome (IFIS) and its association with tamsulosin describes several approaches to managing the surgical complication. The approach a surgeon uses will depend on the severity of IFIS, he says.
You can negotiate with health plans
November 1st 2008Depending on your location, your specialty, and the size of your practice, insurers may actually want to keep you happy, especially if you threaten to walk away from a bad deal. If nothing else, negotiations may reveal that lowball reimbursement for a particular code is nothing more than an inadvertent mistake that most insurers are willing to correct.
How to collect past-due payments from patients without scaring them away
November 1st 2008Physician groups are adopting tougher collection tactics, largely in response to tough times. What compounds their problem of skimpy third-party reimbursements and rising overhead is having to depend on patients for a bigger portion of their revenue stream-a result of the rising number of uninsured and the growth of high-deductible health plans.
Evaluating your competition: industry and non-industry
November 1st 2008Losing even one patient to another local practice is one too many. To achieve and maintain an edge in the LASIK market, you've got to stay on top of your competitors with research and analysis, and regularly evaluate where you fit in terms of image and consumer perception.
