Leaders in Managing the Business of Ophthalmology CER TIFIED O E F OPHTHALMIC EXECUTIVE PRESBYOPIA February 2012 Correcting continued from page 72 The risk of infection is dramati- cally less when the surgeon leaves the corneal surface intact because a flap procedure may allow bacteria into the cornea, which could lead to infection, Dr. Holzer said. Dr. Holzer said in his 3-year fol- low-up, patients showed no change in the shape of the cornea or in the refraction. This shows the procedure is stable. The typical INTRACOR patient has not developed cataracts, although it is possible for a post- cataract surgery patient to have the procedure. IOL calculation after INTRACOR is not a problem, Dr. Holzer said. Patient selection for INTRACOR is important because the procedure is not easy to reverse. "To reverse it would mean doing EYE Robert S. Gold, MD YE PHYSICIANS OF CENTRAL FL LONGWOOD, FL SIC a kind of topography and a wave- front-guided surface excimer laser. It's not as easy to reverse it as taking a multifocal IOL out of the eye," Dr. Holzer said. Dr. Holzer shared 2-year data from the University of Heidelberg study as well as his clinic's 3-year follow-up data. "The endothelial cell count did not show significant differences be- fore and after surgery, corneal topog- raphy showed slight refractive changes, and post-operative stray light measurements were well within the normal age range," the study said.

Among the 25 patients treated, the mean UCNVA increased from 20/100 (logMAR 0.7) to 20/30 (log- MAR 0.26) within 3 months post-op, with this difference being statisti- cally significant (P<0.01). The mean distance sphere changed from +0.75±0.23 D pre-op to +0.15±0.31 D at 3 months post- op, while the cylinder showed mini- mal difference. Uncorrected and best-corrected distance visual acuities were stable over 3 months. UCVA improved from 0.70±0.60 to 0.26±0.21 logMAR, distance cor- rected NVA improved from 0.59± 0.12 to 0.23±0.18 logMAR, and best corrected NVA was unchanged after 3 months. "We have not seen any severe side effects," Dr. Holzer said. He added that vision is blurry for several hours after the surgery, caused by gas bubbles that form dur- ing the ablation. Vision clears when the bubbles do. Investigators now are looking at further refractive indications for INTRACOR, including low myopia, hyperopia, and astigmatism. EW Reference 1. Waring G IV.
