Refractive lens exchange to become dominant refractive procedure, expert says
November 16th 2003The future of refractive lens exchange is quite promising, according to refractive guru I. Howard Fine, MD, who spoke during the AAO's refractive subspecialty day meeting. He predicted that refractive lens exchange will some day become the dominant refractive procedure because it is able "to address all components of patients' refractive errors, including presbyopia."
Therapeutic decisions for glaucoma patients weigh benefits
November 15th 2003Chicago-IOP control remains the basis for primary treatment of glaucoma, but there have been some recent changes in the medical and surgical arenas. Now, a prostaglandin analogue is often used instead of a beta-blocker as first-line therapy, selective laser trabeculoplasty (SLT) has emerged as another option for primary laser surgery, and meanwhile, there is growing patient interest in complementary medicine alternatives.
Hone listening skills to gain patients' trust, boost capture rates
November 15th 2003Patients considering refractive surgery are understandably nervous about undergoing procedures on their eyes. A physician who can listen to their concerns and address them all will gain their trust and their business.
AMO sharpens focus on innovative technology
November 15th 2003A sign of an excellent company is one that capitalizes on its strengths, minimizes its weaknesses, takes advantage of its opportunities, and recognizes its threats, according to James V. Mazzo, president and chief executive officer of Advanced Medical Optics (AMO).
Ultra-small incision technique optimal for vision outcomes
November 15th 2003Chennai, India-Phakonit (Phako with a Nee-dle Incision Technology) is a bimanual approach to phacoemulsification performed with a needle opening via an incision and with the phaco tip. The technique drastically reduces incision size, and with the ad-vent of ultra-small incision IOLs, it offers cataract patients the advantages of astigmatism-neutral sur-gery with return to stable vision within 4 to 5 days after surgery, said Amar Agarwal, MD, an innovator of the technique.
Early results show antibody fragment beneficial for wet AMD
November 15th 2003New York-Treatment with ranibizumab (Lucentis, Genentech) resulted in stable or im-proved vision in 97.5% of patients with wet age-related macular degeneration (AMD) over 6 months, according to the phase Ib/II trial results. Forty-five percent had more than a three-line gain in vision, said Jeffrey S. Heier, MD, a principal investigator in the clinical trial, who reported results at the annual meeting of the American Society of Retina Specialists.
Accuracy in IOL power calculation critical to refractive success
November 15th 2003We often hear how cataract surgery is becoming refractive surgery. In fact, cataract surgery became refractive surgery when Sir Harold Ridley implanted the first IOL. While cataract extraction provides an immediate benefit by clearing the optical media, the patient must rely on the refractive power of the IOL for the rest of his or her life. Getting that refractive power right falls within the purview of refractive surgery, and it involves more than inserting the IOL into the capsular bag.
Merit of customized ablation measured in quality of vision
November 15th 2003Charleston, SC-In an ongoing prospective study, conventional and custom wavefront-guided LASIK have been shown to achieve uncorrected visual acuity (UCVA) outcomes exceeding the FDA grid, but there are dramatic differences favoring the wavefront-guided approach in analyses of treatment effects on higher-order aberrations, said Kerry D. Solomon, MD.
Microsurgical cutting instrument makes consistent incisions
November 15th 2003The Terry-Schanzlin Astigmatome System with vacuum speculum (Oasis Medical Inc.) is a disposable microsurgical cutting instrument designed to make uniform and controlled paralimbal incisions that are often used in combination with cataract and lens implant pro-cedures to reduce astigmatism.
Laser system yields high rate of patient satisfaction in study
November 15th 2003Rochester, NY-The Technolas 217 Z Zyoptix Personalized Vision Correction system (Bausch & Lomb) was approved by the FDA for use in the United States last month (see related news on Page 1). About 99% of patients expressed extreme satisfaction or satisfaction with the visual results afforded them by the system, which may increase patient interest in refractive surgery.
Hyperopic LASIK results impressive at 6-month follow-up
November 15th 2003Pekin, IL-Results from 6 months of follow-up in the Allegretto Wave (WaveLight Laser Technologie, Erlangen, Germany, and Lumenis) hyperopic LASIK clinical trial demonstrate excellent efficacy, safety, accuracy, and predictability, said William I. Bond, MD.
Time to enhance re-treatment of LASIK overcorrections
November 15th 2003The incidence of overcorrection after LASIK for myopia is low, but the results of re-treatment are variable. Re-treating often results in a shift back to myopia, leaving the patient unhappy. To improve the results of LASIK enhancement surgery, a new formula is warranted. In 1999, Drs. Lindstrom and co-workers noted that laser treatment achieved different effects in eyes with primary versus secondary hyperopia. They attributed this effect to dynamics of wound healing.
Sometimes the eye can be key to other pathology
November 15th 2003Editor's Note: The eye is the window to our body's health. In this month's column, we examine two ocular findings in children that have led to the discovery of life-threatening kidney disease and examine the life of the physicians who made these connections.
Wavefront technology: making the transition
November 15th 2003The development of wavefront technology is a major advancement in refractive surgery. It appears to deliver overall better results than conventional LASIK, thereby increasing patient expectations. It is imperative that refractive surgeons interested in continuing to perform laser-vision correction develop expertise with this technology. As with all transitions this, too, has a learning curve that must be conquered.
FDA to allow inserts for keratoconus patients
November 15th 2003Des Plaines, IL-Micro-thin prescription inserts (Intacs, Addition Technology Inc.) may be used to reduce or eliminate myopia and astigmatism in patients with keratoconus for whom restoration of functional vision is no longer possible with contact lenses or glasses, under a new designation by the FDA.
FDA panel recommends OK for STAAR's ICL
November 15th 2003Monrovia, CA-The FDA's Ophthalmic Devices Panel of the Center for Devices and Radiological Health is recommending that STAAR Surgical Co.'s Implantable Contact Lens (ICL) be approved with conditions for use in correcting ?3 to ?15 D of myopia and reducing myopia in the range of ?15 to ?20 D.
