Topography Guided Laser
Since the curvature or shape of your cornea (front clear window of your eye) decides, in most cases, whether you are nearsighted (steep curvature), farsighted (flat curvature) or have astigmatism (football shape as opposed to a basketball shape), corneal Topography is helpful in planning Laser Refractive Surgery of all kinds.
In certain eyes where this topography is irregular and uneven, the Laser itself can be programmed to follow that Topographical pattern to help normalize the corneal shape.
This procedure uses a customized excimer laser treatment guided by a topographic map. Preoperatively, multiple consecutive maps are obtained, and this information is transferred to an excimer laser. A sophisticated algorithm interprets the data and constructs a laser ablation pattern where a number of parameters that can be modified including optical zones, depth of treatment, and curvature modified refractive protocols centered over the line of sight.
Dr. Gulani has raised this concept to an ART since his experience has proved that refraction decides vision, not topography and has honed his skills over time to offer proprietary LaZrPlastique techniques to help patients with irregular astigmatism, Keratoconus, Pellucid Marginal Degeneration and Lasik & PRK complications
