The American Academy of Ophthalmology (AAO) continues to work to provide the latest advances in ophthalmology through engaging new formats. At last year's annual meeting, we introduced a combined session with Ophthalmology, the American Journal of Ophthalmology, and Archives of Ophthalmology called The Editors' Choices.

San Diego-Both conventional LASIK and PRK induce higher-order aberrations to a similar extent, but their effects on individual aberrations are distinctly different, according to Capt. Steve C. Schallhorn, MD.

Buenos Aires, Argentina-Contrast sensitivity, a more sensitive and accurate measure of functional vision than Snellen visual acuity, has been shown to improve after both LASIK and LASEK procedures in patients with low-to-moderate myopia, according to Carlos Argento, MD, and Mar?aJos? Cosentino, MD.

Los Angeles-A preliminary analysis of results from the Los Angeles Latino Eye Study (LALES) indicates open-angle glaucoma (OAG) has a high prevalence among older Latinos. In addition, the rate exceeds that found in white populations and is at least comparable with that seen among blacks, said Rohit Varma, MD, MPH.

New York-The North American Scientific Symposium on Age-Related Vision Impair-ment will focus on age-related macular degeneration (AMD), diabetic retinopathy, and glaucoma. The two-day conference at Lighthouse International's headquarters here Oct. 16 to 17 is presented by Lighthouse International, AMD Alliance International, and the Canadian National Institute for the Blind.

San Francisco-An interim analysis of data from an ongoing European multicenter study of the Phakic Refractive Lens (PRL, CIBA Vision/Medennium) indicates that the posterior chamber implant is a safe, effective, and predictable method for correcting high myopia, said Bo Philipson, MD, PhD, at the annual meeting of the American Society of Cataract and Refractive Surgery.

Fort Lauderdale, FL-Blocking the canaliculus with silicone punctal plugs has been shown to improve the stability of the tear film, decrease the ocular surface staining scores and squamous metaplasia grades, and increase the goblet cell density, according to Dilek Dursun, MD.

Jacksonville, FL-The chances of pterygium recurrence can be decreased substantially by removing the entire pterygium, not simply the head. In cases of extensive excision, amniotic membrane transplantation seems to provide excellent results, according to Arun Gulani, MD.

Houston-Developing a basic understanding of the relationships among wavefront, contrast sensitivity, and Snellen visual acuity and how each describes quality of vision is critical to interpreting studies investigating the efficacy and safety of wavefront-guided refractive surgery, noted Jack T. Holladay, MD, MSEE, FACS.

San Francisco-The integration of refractive error information obtained with a wavefront aberrometer into surgical planning may improve the results of conventional LASIK, said David R. Hardten, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.

San Francisco-Intraoperative pachymetry is important in eyes undergoing LASIK because corneal thicknesses measured just before the microkeratome pass differ significantly from values obtained on a preoperative day, and at least when using the Hansatome microkeratome (Bausch & Lomb), correlate significantly with flap thickness, said Michael A. Redmond, MD, at the American Society of Cataract and Refractive Surgery annual meeting.

San Francisco-Wavefront aberrometry is a valuable tool for understanding the etiology of visual complaints post-LASIK in some patients with large pupils and appears to be promising as well for guiding "custom upgrade" procedures to address debilitating symptoms in those cases, said James J. Salz, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.

San Francisco-Femtosecond laser technology (Intralase FS laser, IntraLase Corp.) provides LASIK surgeons a more precise, predictable method for creating a corneal flap than the conventional mechanical microkeratomes, explained two LASIK experts at the American Society of Cataract and Refractive Surgery annual meeting.

Mesa, AZ-A one-pass scleral-corneal incision technique seems to "offer the best of both worlds" to cataract surgeons, according to Neal Nirenberg, MD, who uses the technique almost exclusively for his cataract patients in his private practice in Mesa, AZ.

St. Paul, MN-The North American Neuro-Ophthalmology Society (NANOS) has been approved as a regular organizational member of the Joint Commission on Allied Health Personnel in Ophthalmology (JCAHPO).

Irvine, CA-The FDA has issued ISTA Pharmaceuticals Inc. an approvable letter for Istalol (timolol), a once-daily liquid formulation for the treatment of glaucoma.

Kansas City, MO-The combination of endoscopic medial wall and floor and transcutaneous lateral orbital decompression used to treat Graves' orbitopathy has a low risk of morbidity, but may not result in as much anatomic retropulsion of the globe as other methods, according to W. Abraham White, a medical student at the University of Missouri-Kansas, Kansas City, MO. White presented an analysis of results achieved by one otolaryngologist and one ophthalmologist using this method.
