PURPOSE To evaluate the optical quality after laser in situ keratomileusis (LASIK) or serial photorefractive keratectomy (PRK) using a double-pass system and to follow the recovery of optical quality after laser vision correction. METHODS This study measured the visual acuity, manifest refraction and optical quality before and one day, one week, one month, and three months after laser vision ...

PURPOSE Identify ideal profiles in patients undergoing to photorefractive laser surgery with the aid of an automated pupillometry and psychometric analysis of patients with visual function questionnaire (VQF 25). METHODS Seventy-seven patients undergoing photorefractive laser surgery laser (LASIK) were analyzed with the aid of an automated digital pupillometer based on an infrared camera coup...

Journal of Refractive Surgery Volume 17 May/June 2001 ABSTRACT PURPOSE: To review the etiology, prevention, and management of laser in situ keratomileusis (LASIK) complications. METHODS: Review of literature and the experience of the authors. RESULTS: Careful preoperative screening is critical to prevention of many potential complications of LASIK. Flap complications that occur during surgery a...

Single-molecule fluorescence spectroscopy addresses biological mechanisms and enables ultrasensitive diagnostics. We describe a new family of single-molecule fluorescence methods that uses alternating-laser excitation (ALEX) of diffusing or immobilized biomolecules to study their structure, interactions, and dynamics. This is accomplished using ratios that report on the distance between and the...

UNLABELLED Laser in situ keratomileusis (LASIK) articles published between 2008 and 2015 that contain clinical outcomes data were reviewed and graded for quality, impression, and potential bias. All 97 relevant articles (representing 67 893 eyes) provided a positive or neutral impression of LASIK. Industry bias was not evident. The aggregate loss of 2 or more lines of corrected distance visual ...

trations after oral dosing. The infection was successfully eradicated with preservation of ambulatory vision. This first case of postoperative VRE endophthalmitis is an unfortunate milestone in ophthalmic surgery. Future cases are probably inevitable given the trends in the epidemiology of VRE infection and colonization, especially in patients with compromised immunity. Colonized donor corneal ...

There has been the unsubstantiated clinical impression that laser refractive surgery accelerates cataract development along with solid experimental data about the cataractogenic effects of excimer laser treatment. We present the first documented case of significant cataract formation in a young myope after repeat excimer laser ablation necessitating phacoemulsification with a posterior chamber ...
