PURPOSE To assess the outcomes of conductive keratoplasty (CK) for patients with complications related to LASIK or photorefractive keratectomy (PRK). DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Sixteen eyes of 15 patients were treated using CK after complications of initial LASIK or PRK surgeries. Five cases are described in detail. INTERVENTION Rehabili...

Swept-source optical coherence tomography (OCT) is the latest advancement in anterior segment imaging. There are limited data regarding its performance after laser in situ keratomileusis (LASIK). We compared the reliability of swept-source OCT and Scheimpflug imaging for evaluation of corneal parameters in refractive surgery candidates with myopia or myopic astigmatism. Three consecutive measur...

PURPOSE To evaluate outcomes of laser in situ keratomileusis (LASIK) guided by wavefront alone versus wavefront plus topographic data. SETTING NewVision Clinics, Cheltenham, Australia. METHODS Twenty-one eyes (14 patients) were distributed into 2 groups in a prospective double-masked study. One group was treated by wavefront parameters alone (WF, n = 11), and the other, by wavefront combine...

Nearsighted individuals typically have problems seeing well at a distance and are forced to wear glasses or contact lenses. The nearsighted eye is usually longer than a normal eye, and its cornea may also be steeper. Therefore, when light passes through the cornea and lens, it is focused in front of the retina. This will make distant images appear blurred. There are several refractive surgery s...

Abstract Purpose To compare early clinical outcomes of single-step transepithelial photorefractive keratectomy (tPRK) and (PRK) regarding refractive outcome, visual acuity, wound healing, pain intensity recovery time.d. Methods In this prospective observational study 200 eyes 100 consecutive patients with mild to moderate myopia or without astigmatism were included. One hundred each either trea...

PURPOSE To compare the visual outcomes of LASIK procedures in which flaps were created with a femtosecond laser (IntraLase FS 60Hz, Abbott Medical Optics [AMO]) to procedures in which flaps were created with a mechanical microkeratome (Moria Evo3 One Use-Plus, Moria SA). METHODS A retrospective analysis was performed on 2000 eyes treated in 2008 for low myopia and astigmatism (sphere < -3.00 ...

PURPOSE To characterize the clinical effects of laser in situ keratomileusis (LASIK) on the cornea and visual performance by the contrast sensitivity function (CSF). SETTING Clinique d'Ophtalmologie IRIS, Laval, Quebec, Canada. METHODS Thirty-four patients aged 18 to 50 years volunteered for this prospective study. All patients had bilateral LASIK to correct myopia between -1.00 and -6.75 d...

BACKGROUND Some myopia patients with unsatisfactory corneas consider corneal refractive surgery for different reasons. Accelerated corneal collagen crosslinking (ACXL) is an effective method to enhance the resistance of the cornea. The present investigation was designed to evaluate the changes of biomechanical properties in patients with myopia and thin corneas after femtosecond-laser in situ k...

purpose: to evaluate the visual outcomes of lasik in myopic eyes. methods: this interventional case series was performed on records of 345 eyes of 179 patients for correcting myopia with astigmatism < 3.00 diopter (d). all patients were operated by one surgeon (h.n.) with the nidek ec 5000 excimer laser. all patients had at least one year follow up. based on preoperative refraction, patients we...
