Fort Lauderdale, FL-Differences in local capillary blood speed characteristics in patients who have unilateral nonarteritic anterior ischemic optic neuropathy (NAION) and optic neuritis (ON) may help in the differential diagnosis of these two most common nonglaucomatous optic neuropathies, said Nathalie Collignon, MD, at the annual meeting of the Association for Research in Vision and Ophthalmology.

Philadelphia-Fibrin glue, approved by the FDA to seal blood vessels, can be used for lamellar keratoplasty to keep the donor cornea in place until it is completely healed 2 to 3 weeks postoperatively, according to Herbert E. Kaufman, MD, who spoke during the Innovator's Session at the American Society of Cataract and Refractive Surgery annual meeting here.

Philadelphia-Improved visual outcomes were seen with wavefront-guided laser ablations because both lower- and higher-order aberrations were reduced. The residual higher-order aberrations were lower than those found in conventionally treated eyes, according to Stephen Brint, MD, who reported results from the CustomCornea study group here at the annual meeting of the American Society of Cataract and Refractive Surgery.

Philadelphia-Excimer laser treatment using the Custom Cap (VISX, Sunnyvale, CA) method seems to be a promising therapeutic approach for reducing optical aberrations in eyes with less than satisfactory visual outcomes after refractive surgery.

Philadelphia-The Allegretto Wave excimer laser (WaveLight Laser Technologie AG, Erlangen, Germany) appears to be safe and effective when used for LASIK to correct myopia and myopic astigmatism. Ablations performed using this laser also seem to produce very little high-order aberration and coma after treatment, even when treatment is not guided by wavefront technology.

Philadelphia-High astigmatism is often more difficult to manage because these patients may have various corneal problems, such as keratoconus, previous RK, or corneal grafts. Multiple strategies should be considered for providing maximal correction and protecting the corneal integrity, explained James P. Gills, MD, during the Innovator's Session at the American Society of Cataract and Refractive Surgery annual meeting.

Philadelphia-Patients with high myopia and high hyperopia seemed to have a good response to the implantation of the Phakic Refractive Lens (PRL, Medennium Inc.), according to Kenneth J. Hoffer, MD, who reported on the phase III trial for myopia and the phase II trial for hyperopia during the American Society of Cataract and Refractive Surgery meeting here.

Philadelphia-LASIK is still a popular procedure although PRK and LASEK are gaining interest, according to the results of the 2nd annual world-wide refractive surgery survey conducted through the American Society of Cataract and Refractive Surgery (ASCRS) and the European Society of Cataract and Refractive Surgery.

Philadelphia-Most of the patients treated for high myopia with the Implantable Contact Lens (ICL, STAAR Surgical) were satisfied with their vision at the 2-year follow-up, said John A. Vukich, MD, who reported the interim results of the FDA clinical trial during the American Society of Cataract and Refractive Surgery annual meeting.

Seattle-The body's natural wound-healing processes that repair a cornea scraped by a tree branch might interfere with the outcome of a LASIK procedure, according to Steven E. Wilson, MD.

Philadelphia-The K-TOME microkeratome offers a range of desirable characteristics that make it an excellent choice for refractive surgeons, but unsurpassed control tops that feature list, said J. Charles Casebeer, MD. He spoke about the instrument, introduced in 1997 by Innovative Optics. Paradigm Medical Industries acquired that company last January and launched the K-TOME at the annual meeting of the American Society of Cataract and Refractive Surgery (ASCRS) here.

Progressive lenses have become the lens of choice to correct presbyopia. Although the demand and popularity of progressive lenses have increased, some doctors avoid prescribing these lenses because of past negative experiences with early lens designs and common axioms.
