Topography-modified refraction (TMR): adjustment of treated cylinder amount and axis to the topography versus standard clinical refraction in myopic topography-guided LASIK
PURPOSE To evaluate the safety, efficacy, and contralateral eye comparison of topography-guided myopic LASIK with two different refraction treatment strategies. SETTING Private clinical ophthalmology practice. PATIENTS AND METHODS A total of 100 eyes (50 patients) in consecutive cases of myopic topography-guided LASIK procedures with the same refractive platform (FS200 femtosecond and EX500...
متن کاملOutcomes of topography-guided versus wavefront-optimized laser in situ keratomileusis for myopia in virgin eyes.
PURPOSE To compare the outcomes of topography-guided and wavefront-optimized treatment in patients having laser in situ keratomileusis (LASIK) for myopia. SETTING Advanced Eye Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, India. DESIGN Prospective contralateral-eye case study. METHODS Patients had topography-guided LASIK in 1 eye and wavefront-optimized LA...
متن کاملMeasurement and Topography Guided Treatment of Irregular Astigmatism
Corneal astigmatism occurs when one corneal meridian has a different refractive power from the orthogonal meridian. In regular astigmatism, the two meridians are at 90o from each other, such as a sphere having a cylinder superimposed on its surface. In irregular astigmatism the two meridians are not at 90o from each other or the cornea curvature is not axially symmetric. Irregular astigmatism c...
متن کاملCalculation of intraocular lens power using Orbscan II quantitative area topography after corneal refractive surgery.
PURPOSE To present the prospective application of the Orbscan II central 2-mm total-mean corneal power obtained by quantitative area topography in intraocular lens (IOL) calculation after refractive surgery. METHODS Calculated and achieved refraction and the difference between them were studied in 77 eyes of 61 patients with previous radial keratotomy (RK), RK and additional surgeries, myopic...
متن کاملTwo-step LASIK with topography-guided ablation to correct astigmatism after penetrating keratoplasty.
PURPOSE To assess the efficacy, predictability, stability, and safety of a two-step LASIK procedure using topography-guided ablation to correct astigmatism after penetrating keratoplasty. METHODS Fifteen eyes of 15 patients underwent a two-step LASIK procedure at the Maggiore Hospital of Bologna, Italy. In the first step, a flap was created using the Hansatome microkeratome. In the second ste...
