Jackson lecturer seeks ways to reduce corneal measurement inaccuracies

CHICAGO — A healthy cornea, optimal tear function, accurate devices capable of taking both anterior and posterior measurements, and ways to noninvasively adjust postoperative refraction can help a surgeon accurately record cornea measurements and IOL calculations, Douglas D. Koch, MD, said in his delivery of the Jackson Memorial Lecture here.“The requirement that we have for reducing and managing corneal measurement errors, is, of course, [that] our patient’s corneas need to be optimized. They need to be as healthy as possible with optimal tear function,” Koch said at the American Academy of Ophthalmology meeting. “We need well trained technicians, and we need to be skeptical surgeons to critically evaluate the data provided to us. And, presumably, we’ll get data from more than one device in order to cross check.”
