Laser refractive eye surgery

Laser refractive eye surgery.

Laser 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...

Surgeon 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...

Overview of laser refractive surgery.

Since approval of the use of the excimer laser in 1995 to reshape the cornea, significant developments in the correction of refractive errors such as myopia, hyperopia, and astigmatism have been achieved. Combined with other advanced ophthalmological instruments (e.g. anterior segment imaging systems, the femtosecond laser, wavefront-guided customized ablation) and the knowledge accumulated con...

Topography-guided laser refractive surgery.

PURPOSE OF REVIEW Topography-guided laser refractive surgery regularizes the front corneal surface irregularities to achieve the desired refractive outcome. This is particularly applicable in highly aberrated corneas, where wavefront aberrometry is often not possible. This article aims to review the recently published results of topography-guided ablations in normal regular corneas, highly aber...
