PURPOSE To report infraorbital nerve dysfunction after laser in situ keratomileusis. DESIGN Observational case report. METHODS Neuro-ophthalmologic examination with brain and orbital magnetic resonance imaging (MRI) and orbital computed tomography (CT). RESULTS During laser in situ keratomileusis, two healthy women, aged 42 and 46 years, experienced acute onset of sharp ipsilateral cheek ...

OBJECTIVE To evaluate the effects of excimer laser in situ keratomileusis in correcting severe myopia and astigmatism after penetrating keratoplasty. METHODS Excimer laser in situ keratomileusis was performed on ten eyes of ten patients to correct high ametropia in cases having previously undergone penetrating keratoplasty. RESULTS After surgery, all grafts remained clear and no corneal gra...

BACKGROUND A new technique, therapeutic alloplastic laser in situ keratomileusis to correct high myopia, is introduced. METHODS Therapeutic alloplastic laser in situ keratomileusis consists of neutral homoplastic epikeratoplasty combined with superficial keratectomy performed with an excimer laser and/or a microkeratome. Indications for the technique are: myopia over 20 diopters (D), eyes wit...

In this article, we use a longitudinal census of laser in situ keratomileusis (LASIK) eye surgeries collected directly from patient charts to examine the learning-by-doing hypothesis in medicine. LASIK surgery has precise measures of presurgical condition and postsurgical outcomes. Unlike other types of surgery, the impact of unobservable underlying patient conditions on outcomes is minimal. In...

Purpose: To evaluate the safety and reproducibility of using +3 Ring Moria M2 microkeratome (Mechanical Technology) with patients suffering from high K reading. Setting: Eye Care Private Centre-surgery Centre, Jeddah, Saudi Arabia. Methods: Data had been reviewed starting from 2005 up to 2010; with the aim to review and evaluate all the data and complications after using +3 Ring Moria M2 single...

PURPOSE To evaluate the effect of laser in situ keratomileusis (LASIK) on stereoacuity (SA). METHODS This prospective study includes 200 patients scheduled for LASIK. SA was evaluated preoperatively and one week, one month and three months postoperatively using the Random Dot test. Patients with preoperative SA worse than 480 sec/arc were excluded from the study. RESULTS The study included ...

Optical side-effects of fs-laser treatment in refractive surgery are investigated by means of a model eye. We show that rainbow glare is the predominant perturbation, which can be avoided by randomly distributing laser spots within the lens. For corneal applications such as fs-LASIK, even a regular grid with spot-to-spot distances of ~3 µm is sufficient to minimize rainbow glare perception. Con...

High astigmatism correction represents a challenge for the refractive surgeon with current available technology. Excimer laser correction should be considered as an option in the available therapeutic arsenal. We report a patient with astigmatism higher than eight diopters to whom it was used a treatment with LASIK (Laser Assisted In Situ Keratomileusis) in two surgical moments, using a new gen...
