Editor's Note: It has been a great pleasure and an honor to have been able to work with the editorial staff of Ophthalmology Times in creating the Cataract Corner column over the past 5 years. However, at this time I take equal pleasure in turning over the column to my two associates, Dr. Richard Hoffman and Dr. Mark Packer, both of whom are superb surgeons, excellent clinicians, great speakers, and experienced researchers. They represent the next generation of leadership in cataract and refractive surgery, and I'm sure the readers of this column will enjoy their perspective and input as they

Ann Arbor, MI-Results from gene microarray studies by researchers at the University of Michigan reveal there are highly specific, age-related changes in retinal gene expression. Those findings are described in the August issue of Investigative Ophthalmology and Visual Science [Yoshida S, et al. IVOS 2002; 43:2554-2560].

Fort Myers, FL-A comparison of two laser systems, the STAR S2 (VISX, Santa Clara, CA) and the LadarVision (Alcon, Fort Worth, TX), used to treat low to moderate levels of myopia indicated that the visual results after LASIK were similar between the two but that visual recovery appeared to be faster with the STAR S2.

A 42-year-old Hispanic male presented complaining of decreased vision in his left eye. He noted that his vision in that eye had decreased suddenly three weeks earlier. The patient had low hyperopia. His medical, surgical, and family histories were unremarkable. He was using no medications and had no known drug allergies. Although he initially reported no significant social history, after more extensive questioning he admitted to the occasional inhalational use of cocaine. His most recent use was on the day prior to the onset of his visual disturbance.

San Diego-Several higher-order aberrations have been correlated with patients' visual complaints after LASIK. Because wavefront technology appears to reduce the induction of higher-order aberrations after LASIK, wavefront-guided ablations may improve the visual outcomes after LASIK, according to Steven C. Schallhorn, MD.

Atlanta-The risk of corneal ectasia following LASIK is greater in patients with form fruste keratoconus, more than -8 D of myopia, and residual stromal beds that are thinner than 225 ?m. Most of the patients who developed corneal ectasia, however, were able to obtain a good visual outcome with contact lens correction, according to R. Doyle Stulting, MD, PhD.

Rockville Centre, NY-Implantation of a posterior chamber phakic refractive lens (PRL) (Medennium phakic refractive lens, CIBA Vision, Duluth, GA) demonstrated positive visual outcomes in the treatment of high hyperopia, according to Alexander Hatsis, MD, who presented the results of the FDA phase II trial.

Warner Robins, GA-Diagnosis and treatment of late-onset microbacterial infections with amikacin after LASIK results in good visual recoveries. However, other refractive procedures, such as PRK or LASEK, will decrease the incidence of these types of infections, most of which result from creation of the flap, according to Johnny L. Gayton, MD.

Baltimore-Race, that ever-sensitive subject in American culture, was the focus of a day-long meeting, "Ethnicity & Glaucoma: The Past, Present, and Future," at Johns Hopkins' Bloomberg School of Public Health.

Fremont, CA-Nidek Inc. has submitted its hyperopia PMA clinical module to the FDA for review and approval of its EC-5000 Excimer Laser System for hyperopia, hyperopic astigmatism, and mixed astigmatism. This marks the final step in gaining commercialization approval by the FDA to market and treat indications of hyperopia with the Nidek system.

Nice, France-Preliminary data suggest that visual outcomes are excellent with the VISX WavePrint ablation method (VISX) for custom laser vision correction. At the European Society of Cataract and Refractive Surgery meeting, Douglas D. Koch, MD, described results of the VISX Study Group with 171 patients. He is professor of ophthalmology, The Allen, Mosbacher, and Law Chair in Ophthalmology, Cullen Eye Institute, Baylor College of Medicine, Houston.

All Joint Meeting attendees may participate in the PAAO programs that include instruction courses and symposia. All PAAO instruction courses and symposia were selected by the PAAO's Scientific Program Committee.

Washington, DC-Co-management of cataract and refractive surgery patients may seem like a risky endeavor for ophthalmologists, exposing them to liability under the anti-kickback law. However, this doesn't have to be the case, noted Michael A. Romansky, JD.
