Determining the accuracy of an eye tracking system for laser refractive surgery.
PURPOSE Patient eye and head movements during laser refractive surgery may result in errors between the surgical beam position and the desired location for optimum correction. This, in turn, may lead to reduced postoperative vision, including increased higher order aberrations of the eye. Active eye tracking systems are often incorporated into laser delivery systems, which aim to reduce the eff...
متن کاملLaser eye surgery for refractive errors.
Several laser and non-laser refractive surgical procedures have been used to modify the shape of the cornea and correct myopia, hyperopia, astigmatism, and presbyopia. Introduction of the excimer laser to reshape the cornea has resulted in remarkable developments in the correction of these refractive errors. Combined with other advanced ophthalmological instruments, laser refractive eye surgery...
متن کاملSurgeon offsets and dynamic eye movements in laser refractive surgery.
PURPOSE To determine the amount of static and dynamic pupil decentrations that occur during laser refractive surgery. SETTING The Center of Visual Science and the Department of Ophthalmology, University of Rochester, Rochester, New York, USA. METHODS The surgeon's accuracy in aligning the pupil center with the laser center axis was measured when engaging the eye-tracker in 17 eyes receiving...
متن کاملThe current state of refractive surgery
The leading topic of this particular paper is dedicated to available surgical options for refractive eye disorders treatment including surgery of cornea and intraocular surgery. Corneal Surgery includes laser refractive surgery - LASIK (Laser-Assisted In Situ Keratomileusis), FemtoLASIK (Femtosecond laser-assisted LASIK), PRK (Photorefractive keratectomy). This article describes relevant princi...
متن کاملRefractive Surgery Feature Story
H uman eyes are capable of six types of movement: x/y lateral shifts, z levelling, horizontal and vertical rotations, and cyclotorsion (rotation around the optical axis). Current laser technology for refractive surgery creates corneal alterations to correct refractive errors more accurately than in the past.1 Ablation profiles are based on the removal of tissue lenticules through sequential las...
متن کاملPrediction of Refractive Outcome of Second Eye with Partial Adjustment of Intraocular Lens Power of the First Eye
Background and Objective: This study aimed at comparing the results of refractive cataract surgery in patients undergoing sequential surgeries in both eyes. Considering the preoperative refraction and final refraction of the first eye, it is possible to correct the refrative result of cataract surgery using the adjustment of the second eye intraocular lens (IOL) power. Materials and Methods: T...
