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.

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.

Loteprednol etabonate ophthalmic suspension 0.2% (Alrex, Bausch & Lomb Pharmaceuticals and Pharmos Corp.), the so-called "safe steroid" approved for treatment of seasonal allergic conjunctivitis, appears to be living up to its billing, according to several ophthalmologists who prescribe the drug for a range of ophthalmic allergies.

Fort Lauderdale, FL-Cyclosporine A drops may be an effective treatment for Thygeson's superficial punctate keratitis (SPK) over the long term. It is especially useful in patients whose disease does not respond to treatment with steroids or those whose disease responds to steroids and who have elevated IOP levels, according to the results of a U.K. study reported at the Association for Research in Vision and Ophthalmology.

With a host of allergy medications from which to choose, clinicians need to thoroughly explore patient history before determining which drug is most appropriate for each individual.

Fort Lauderdale, FL-A twice-daily dosing regimen of pemirolast potassium 0.1% ophthalmic solution (Alamast, Santen Inc., of Napa, CA, and Tampere, Finland) is as effective as the four-times-daily regimen of the drug for treating seasonal allergic conjunctivitis.

San Francisco-Should a patient's race play a role in an ophthalmologist's decision as to which glaucoma medications to use? Shan C. Lin, MD, believes evidence to do so is lacking.

Adelaide, South Australia-For patients with periocular lentigo maligna and lentigo maligna melanoma, slow Mohs' surgery may be the answer. The procedure is a combination of rush processing of paraffin-embedded sections and mapped margin-controlled excision, which provides tissue conservation and the best cure rate compared with other treatments, such as unmonitored surgical excision, according to Raman Malhotra, MBChB, FRCOphth.

Fort Lauderdale, FL-Analyses of data collected in the Blue Mountains Eye Study (BMES) provide evidence for a relationship between open-angle glaucoma (OAG) and thyroid disease, and particularly hypothyroidism, said Anne J. Lee, MBBS, at the annual meeting of the Association for Research in Vision and Ophthalmology.

San Francisco-Preoperative corneal thickness is the most important predictor of achieved flap thickness using the Hansa-tome (Bausch & Lomb) microkeratome, but preoperative spherical equivalent (SE) and microkeratome head choice also play a role, according to the results of a study presented by Jay S.
