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.Refractive lens exchange increases retinal detachment risk- September 15, 2006 Manchester, England—Retinal detachment (RD) is a significant risk in refractive lens exchange (RLE) surgery for high myopia, said Emanuel S. Rosen, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Refractive-lens-exchange-i... Epi-LASIK favored over tPRK for myopia treatment- September 15, 2006 San Francisco—Treatment of low-to-high myopia with transepithelial PRK (tPRK) has poorer predictability and results in greater induction of corneal spherical aberration compared with epi-LASIK, reported Osamu Hieda, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Epi-LASIK-favored-over-tPR... Initial experience good with accommodating IOL- September 15, 2006 San Francisco—In an initial analysis, the Synchrony dual-optic single-piece IOL (Visiogen) performed well. The visual results were good, there were no major complications and no glare or halos after implantation, and patient satisfaction was high, according to George Beiko, BM, BCh, FRCS.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Initial-experience-good-wi... Wavefront ablations vary in time required- September 1, 2006 Wavefront preparation time plus the surgical time equals the actual time of the procedure. Different factors associated with each platform add to the preparation time for the procedure.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Wavefront-ablations-vary-i... Corneal onlays in early stages of development- September 1, 2006 San Francisco—Early experience with the use of corneal onlays for refractive correction seems to indicate that extracellular matrix substitutes can be made into onlays that can integrate functionally within host corneas. Epithelial pockets can be created and there is potential for these lenticules to be useful future supplements for, or alternatives to, laser-based refractive correction, according to W. Bruce Jackson, MD, at the annual meeting of the American Society...http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Corneal-onlays-in-early-st... Pupil centroid shift feature allows greater laser accuracy- September 1, 2006 San Francisco—The pupil centroid shift feature of the VISX S4 laser CustomVue platform (Advanced Medical Optics) provides greater visual benefit than does compensation for cyclotorsional rotational registration in eyes with less than 2 D of astigmatism, according to Douglas D. Koch, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Pupil-centroid-shift-featu... Multizone LASIK creates pseudoaccommodative cornea- September 1, 2006 Cannes, France—Multizone LASIK based on creating a central zone for far vision and treating the periphery for near is an effective technique for providing patients who have myopia and hyperopia with good near and distance vision without loss of contrast sensitivity, according to Alain Telandro, MD.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Multizone-LASIK-creates-ps... Corneal transplantation advances with different techniques- September 1, 2006 San Francisco—Corneal transplantation has been evolving. Where once there was penetrating keratoplasty (PK), there is now a new alphabet of corneal transplantation procedures that are more advanced than their older relative. Michael W. Belin, MD, reviewed the major techniques, recounting their advantages and disadvantages at the annual meeting of the American Society of Cataract and Refractive Surgery.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/Corneal-transplantation-ad... IOL provides good distance, near vision in bilateral surgery- September 1, 2006 San Francisco—The AcrySof ReSTOR SA60D3 IOL (Alcon Laboratories) has provided good distance and near vision when used in the setting of bilateral simultaneous surgery, according to Richard B. Packard, FRCS.http://www.modernmedicine.com/modernmedicine/Refractive+Surgery/IOL-provides-good-distance... |
