Also wavefront technology, corneal topography, and more.Laser channel dissection surpasses mechanical approach- February 15, 2007 Las Vegas—The use of a femtosecond laser (IntraLase, Advanced Medical Optics) to create channels for placement of corneal implants (Intacs, Addition Technology Inc.) seems to provide better visual and refractive improvements compared with mechanical implantation of the segments, according to Aylin Ertan, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Laser-channel-dissection-s... Corneal inlay is versatile approach for presbyopia- February 15, 2007 Las Vegas—A small intracorneal inlay (PresbyLens, ReVision Optics) may be an option for LASIK patients who have developed presbyopia, said Roger F. Steinert, MD, during a spotlight session on the management of presbyopia here at the American Academy of Ophthalmology annual meeting.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Corneal-inlay-is-versatile... Mechanical epithelial removal favored in lab study- February 15, 2007 Charleston, SC—Use of a particular computer-driven microkeratome (Amadeus II with EpiBlade, Advanced Medical Optics) results in a better-quality separation of the corneal epithelium compared with an alcohol-assisted technique, according to a laboratory study reported by Luis E. Fernandez de Castro, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Mechanical-epithelial-remo... All-laser refractive surgery has benefits- February 15, 2007 Minneapolis—Three-month results from a retrospective study of LASIK cases performed using the 30-kHz femtosecond laser (IntraLase FS 30, IntraLase Corp.) or a particular microkeratome (Hansatome, Bausch & Lomb) for flap creation indicate that both procedures are associated with excellent efficacy and safety but suggest some benefits for the all-laser surgery, reported Elizabeth A. Davis, MD, FACS, clinical assistant professor of ophthalmology, University of...http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/All-laser-refractive-surge... Patients prefer custom over conventional LASIK ablation- February 15, 2007 Milan, Italy—A comparison of custom and conventional LASIK ablations showed that both procedures provided very good results in terms of the uncorrected and best-corrected visual acuities (UCVA, BCVA) and refractive outcomes. Patients expressed greater quality of vision, however, with the results of the custom treatment, likely because of the better higher-order aberration values in that group, reported Luca Vigo, MD.http://www.modernmedicine.com/modernmedicine/Ophthalmology/Patients-prefer-custom-over-con... Epi-LASIK offers good visual results compared with LASIK- February 15, 2007 Alexandria, Egypt—The debate over the efficacy of epi-LASIK and LASIK continues. Both procedures are safe, although the visual rehabilitation is slower in patients who undergo epi-LASIK. However, the visual results ultimately surpass those who had LASIK, according to Ahmed A. El-Massry, MD, who reported on a comparison study of the two procedures.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Epi-LASIK-offers-good-visu... Troutman Award winner's focus is on wavefront findings- February 1, 2007 Las Vegas—Marcelo V. Netto, MD, was presented with the 16th annual Troutman Award at the annual meeting of the American Academy of Ophthalmology. He received the award as lead author of a paper that described the findings from wavefront analysis in a population of normal refractive surgery patients Netto MV, et al. J Refract Surg. 2005;21:332-338.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Troutman-Award-winners-foc... CK effects, results may be temporary- February 1, 2007 Stanford, CA—Refractive surgeons performing conductive keratoplasty (CK, Refractec) for correction of mild to moderate hyperopia can expect good visual results initially, but they should warn patients that CK effects might not be permanent, explained Jason S. Ehrlich, MD, PhD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/CK-effects-results-may-be-... Multizone LASIK technique considered safe, effective- February 1, 2007 Jeddah, Saudi Arabia—Multizone LASIK with peripheral near zone ablation to correct presbyopia together with myopia or hyperopia is safe, effectively corrects spherical error, and improves near vision but without offering a high rate of spectacle independence, according to a study from refractive surgeons here at the Magrabi Hospital.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Multizone-LASIK-technique-... Aspheric monofocal lens tops spheric lens for contrast sensitivity, study finds- February 1, 2007 London—In an intra-individual comparison of spheric and aspheric monofocal IOLs, significantly better contrast sensitivity was observed in eyes in which the aspheric lens had been implanted, but there was no difference in best-corrected visual acuity (BCVA), said Katrin Petermeier, MD, University Eye Hospital, Eberhard-Karls University, Tuebingen, Germany.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Aspheric-monofocal-lens-to... |
