February 26, 2008 – Los Angeles, CA -- Ophthalmologist David Huang, MD, PhD, a researcher for the Doheny Eye Institute (www.doheny.org), presented a lecture entitled “Intraocular Lens Calculation after LASIK with Anterior Segment Optical Coherence Tomography” at the Reseach Study Club meeting, held in Los Angeles, California on January 12, 2008. 

Selecting the proper power for the intraocular lens implant, commonly inserted after cataract surgery, is a difficult problem for patients who had previous laser vision correction, said Dr. Huang.  Post-LASIK eyes have different curvatures in the front and back of the cornea, so the usual mathematical formulae for calculating lens power do not work well.  This can result in unplanned near- or far-sightedness after cataract surgery.  Dr. Huang has developed a new way to measure corneal curvature with a very high-speed optical coherence tomography (OCT) technology to improve the accuracy of lens power selection. This new method is being tested in a clinical study at the Doheny Eye Institute. 

Ophthalmologists in the Los Angeles area are welcome to refer their patients to this study, which provides corneal measurement and lens calculations without any charge.  The research subjects could then have their cataract surgery with the referring doctor.  The subjects must have previous uncomplicated LASIK or PRK surgery and be willing to return for examination one month after their cataract surgery.  Referring ophthalmologists should contact the research coordinator, Sylvia Ramos, at sramos@usc.edu or 323/442-6383.

This study is sponsored by Optovue, Inc. (www.optovue.com) the company that manufactures the RTVue-CAM high performance Fourier-domain OCT system used to measure corneal power in the study.  Drs. Ronald E. Smith, Jonathan C. Song, Samuel C. H. Yiu and Maolong Tang are co-investigators in this study.
