Ophthalmology Times - Refractive SurgeryRefractive surgery topics including surface ablation, LASIK, intraocular lens (IOL), as well as epi-LASIK, LASEK, photorefractive keratectomy (PRK), penetrating keratoplasty (PKP), penetrating keratectomy (PK) & radial keratotomy (RK). Also wavefront technology, corneal topography, and more.Wavefront-guided enhancements treat post-LASIK error- October 15, 2006 Minneapolis, MN—Wavefront-guided enhancements seem to be very effective for correcting residual refractive error after a primary LASIK procedure. The enhancement procedure using the CustomVue Wavefront system (VISXAdvanced Medical Optics) results in significantly better Snellen uncorrected visual acuity (UCVA) than that achieved with conventional enhancements, according to David R. Hardten, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Wavefront-guided-enhanceme... Synthetic inlays in early study for refractive correction- October 15, 2006 Sydney, Australia—The first synthetic polymer corneal inlays implanted in humans appear to be biocompatible with corneal tissue and represent a safe, biologically acceptable alternative to other forms of refractive surgery, according to observations made over an 18-month period, said Deborah F. Sweeney, B Optom, PhD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Synthetic-inlays-in-early-... Improved safety, precision seen with femtosecond-created flaps in LASIK- October 15, 2006 The introduction of the femtosecond laser for flap creation in LASIK gives refractive surgeons an additional treatment option. But beyond the obvious marketing hype of an &34;all laser&34; LASIK procedure, are there definite clinical benefits to using this keratome over traditional microkeratomeshttp://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Improved-safety-precision-... Presbyopic lens exchange for high myopia problematic- October 15, 2006 Alicante, Spain—While one segment of the ophthalmic community sees presbyopic lens exchange for patients with high myopia as a promising, safe technique leading to good improvements in visual acuity, another segment does not, stating that the risk of retinal detachment and other complications related to the surgery are just too high, according to Jorge L. Alio, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Presbyopic-lens-exchange-f... Refractive surgery weakens the cornea- October 15, 2006 London—The structural integrity of the cornea is compromised by refractive surgeries, and the deeper the surgery is the more compromise takes place, according to John Marshall, PhD, FRCOphth(Hon).http://www.modernmedicine.com/modernmedicine/Cornea/Refractive-surgery-weakens-the-cornea/... Microkeratome offers easy assembly, reliable flap thickness- October 15, 2006 Raleigh, NC—Simplicity is the key word to James Kiley, MD, when he describes the MK-2000 microkeratome (Nidek).http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Microkeratome-offers-easy-... Nomograms can help to improve patient outcomes- October 15, 2006 Lasers are designed to treat people based on averages in a population. However, an individual or a class of individuals may respond slightly differently to the laser pattern that has been designed by the manufacturer.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Nomograms-can-help-to-impr... Excimer laser produces positive results in hyperopia- October 1, 2006 Houston—Hyperopia treated with the wavefront-optimized Allegretto Wave excimer laser (WaveLight) achieved good long-term stability, even in patients with 4 to 6 D of hyperopia. The wavefront-optimized platform also achieved excellent outcomes for hyperopia up to 6 D with 5 D of cylinder, reported Charles R. Moore, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Excimer-laser-produces-pos... Topographically guided ablation helps with transition zone- October 1, 2006 The topographically guided algorithm in the EC-5000 CX (Nidek) excimer laser provided a good visual outcome for patients with myopia, with 95% of patients achieving 2020 or better visual acuity and no induction of total aberrations, according to a study by Mihai Pop, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Topographically-guided-abl... Rochester nomogram helps improve custom LASIK results for myopia- October 1, 2006 Rochester, NY—The Rochester nomogram for custom LASIK provided significantly better postoperative visual acuity, better predictability, and reduced range of postoperative spherical equivalent compared with the previous FDA study in eyes with greater degrees of myopia, according to Manoj Subbaram, PhD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Rochester-nomogram-helps-i... |
