Excimer Laser Surgery: Biometrical Iris Eye Recognition with Cyclorotational Control Eye Tracker System
A prospective comparative study assessing the importance of the intra-operative dynamic rotational tracking-especially in the treatment of astigmatisms in corneal refractive Excimer laser correction-concerning clinical outcomes is presented. The cyclotorsion from upright to supine position was measured using iris image comparison. The Group 1 of patients was additionally treated with cyclorotat...
متن کاملEye-Tracker-Guided Non-Mechanical Excimer Laser Assisted Penetrating Keratoplasty
PURPOSE The purpose of the study was to implement a new eye tracking mask which could be used to guide the laser beam in automated non-mechanical excimer laser assisted penetrating keratoplasty. MATERIALS AND METHODS A new trephination mask design with an elevated surface geometry has been proposed with a step formation between conical and flat interfaces. Two recipient masks of 7.5/8.0 mm ha...
متن کاملEye dominance in excimer laser photorefractive keratectomy.
human species and is relevant in clinical practice—to excimer laser photorefractive keratectomy (PRK) in particular. Due to the complexity of the underlying physiological mechanisms, there is no single definition that applies to all aspects of ocular dominance. Nevertheless, a clinically useful definition would be, “The dominant eye is the eye that is preferred in monocular viewing or in pointi...
متن کاملIris Localisation for a Head-Mounted Eye Tracker
This paper discusses the image processing techniques needed to localise the iris outline in images of the eye produced by a novel, portable eye tracker. The tracker allows gaze direction to be measured by supplying simultaneous views of a subject's eye and of the world from a headmounted camera. Finding gaze direction relative to the head requires accurate and robust measurement of the iris out...
