Phaco machine settings may not match delivery
October 15th 2008In a fluidics test of three phacoemulsification machines, differences were found in vacuum, flow, and postocclusion surge-and these differences were found not only between the three machines but also between the machines' own settings and what they were actually delivering. Other important findings: there is a significant amount of unoccluded vacuum at the tip, and the parameters for what constitutes a safe postocclusion surge can be dramatically different among eyes.
SAILOR 1-year results show safety of two ranibizumab doses
October 15th 2008Low rates of ocular and nonocular adverse events were found in patients receiving either 0.3 mg or 0.5 mg of ranibizumab (Lucentis, Genentech) for neovascular age-related macular degeneration. Final 1-year results from the safety study of over 2,300 patients showed that rates of adverse events were similar to those found in other large studies of ranibizumab.
Analysis: Aging and obesity in the United States
October 15th 2008Changing demographics in the United States will require ophthalmology practices to adopt strategies to deliver care to large numbers of diabetic and elderly patients. Possible steps could include more effective use of support staff and increasingly efficient practice patterns.
Documentary is chronicling vision-loss experiences
October 15th 2008U.S. documentary film director Joseph Lovett he has been progressively losing his vision since glaucoma was diagnosed in him 20 years ago. He is making a film, "Going Blind," to document the effects that blindness has on people's lives and to relay his own experience with the condition.
PBA provides eye safety tips for Halloween
October 9th 2008Prevent Blindness America is reminding everyone to make sure all Halloween purchases are safe and responsible. In the past, cosmetic contacts were popular costume accessories, allowing wearers to change eye color or give the illusion of cat?s eyes.
Best practice management: success from A to Z
October 1st 2008The best practices learn how to hire, train, and retain the best staff, manage patient and staff issues and physician relationships according to Ian Maltzman the administrator for Fromer Eye Centers in New York City. Because Fromer Eye Centers has a very complex organizational structure, including a president, administrator, and a chief operating officer, Maltzman has had to find ways to manage the complex structure.
New administrators need to learn all aspects of ophthalmic practice
October 1st 2008New administrators at an ophthalmic practice should start by learning every non-medical aspect of the practice, including finances, computer maintenance, patient satisfaction components, and staff requirements and rewards systems.
Staying calm when a patient's behavior is out of line
October 1st 2008The typical difficult patient can ruin a perfectly good day at your practice if you let them. By not taking it personally and keeping your cool you can successfully deal with this type of patient without adding stress and frustration for you or the patient.
Built-in efficiencies ensure quality surgeries in high-volume practices
October 1st 2008Practices can increase their efficiency by performing surgery in only one location, having multiple operating rooms (ORs) and an efficient preoperative area available, using anesthesia blocks preoperatively instead of topical anesthesia in the OR, choosing a safe and reliable phaco technique that minimizes surgical time, and hiring well-trained staff members.
Consider masquerade syndromes when a differential diagnosis appears to indicate idiopathic uveitis
October 1st 2008When making a differential diagnosis of idiopathic uveitis, remember that several malignant and non-malignant syndromes can masquerade as the condition. Making the correct diagnosis early allows prompt institution of appropriate therapy and avoids unnecessary treatment.
Mix-and-match approach maximizes refractive lens exchange outcomes
October 1st 2008Three combinations of IOLs for the correction of presbyopia were evaluated in a retrospective analysis. The results favored a mix-and-match approach using the (AcrySof ReSTOR, Alcon Laboratories) and the crystalens (crystalens, eyeonics) for better range and quality of vision, according to one surgeon.
Artificial cornea useful in patients with multiple graft rejections
October 1st 2008In patients who have suffered multiple immunologic graft rejections, the chance of providing good-quality vision is dramatically increased with a keratoprosthesis than another transplant. Patients who receive a keratoprosthesis have rapid visual return, a good quality of vision, and a high rate of graft survival.
Refractive multifocal IOL improves uncorrected vision
October 1st 2008Bilaterial implantation of a refractive multifocal IOL (ReZoom, Advanced Medical Optics) can result in high satisfaction rates among patients undergoing cataract surgery or refractive lens exchange when proper patient selection, aggressive correction of residual refractive error, and early intervention for posterior capsule opacification are part of the strategy, according to a retrospective study of 71 patients.
Ectasia risk scoring system demonstrates excellent predictive ability, according to researchers
October 1st 2008An Ectasia Risk Factor Score System developed by researchers at Emory University appears to be a valid method for identifying patients at risk for ectasia after LASIK, according to a retrospective review of 171 cases of post-LASIK ectasia and 186 controls with normal postoperative courses.
Standardized digital imaging technique aims to increase understanding of intralenticular glistenings
October 1st 2008A technique for obtaining digital photographs under standardized conditions was developed as the foundation for scientific assessment of IOL glistening size and severity, which ultimately will be used to investigate visual impact.
Novel prosthetic device restores vision in eyes with post-LASIK complications
October 1st 2008A novel prosthetic device (Boston Scleral Lens) is custom-designed to vault the cornea over an oxygenated reservoir of artificial tears. It is designed to correct corneal first surface aberrations and address symptoms of dry eye disease.
Technology: investigational aberrometer offers real-time intraoperative refraction
October 1st 2008An aberrometer is being developed to provide cataract and refractive surgeons with a tool for intraoperative assessment of refraction to improve results of astigmatic correction techniques and IOL power selection. Outcomes in an ongoing clinical trial are encouraging.
