Chapel Hill, NC-A unique treatment that personalizes the ablation to the cornea-topography-guided LASIK (Contoura Vision, Alcon Laboratories)-is delivering unsurpassed visual quality and quantity outcomes, said Karl G. Stonecipher, MD.
The treatment is the first topography-guided LASIK to receive FDA approval. It is performed using the WaveLight Topolyzer Vario Diagnostic Device, proprietary treatment planning software, and either the Allegretto Wave Eye-Q or WaveLight EX500 Excimer Laser systems (all Alcon).
It is indicated for use in patients ages 18 years and older for the reduction of up to –9 D of spherical equivalent (SE) myopia or myopia with astigmatism, with up to –8 D of spherical component and up to –3 D of astigmatic component in the spectacle plane. Treated eyes should have a normal cornea (e.g., normal thickness and only minor variations in topography, such as an asymmetric bowtie pattern) and stable refraction.
“Contoura Vision represents an additional option for improving our outcomes with laser vision correction,” said Dr. Stonecipher, who was an investigator in the study and is clinical associate professor of ophthalmology, University of North Carolina, Chapel Hill. “It normalizes the cornea, optimizing the optics, and in the U.S.-based multicenter clinical trial, it was associated with amazing results for improving objective visual acuity measurements and, most remarkably, for improving visual symptoms.”
