PURPOSE To improve the visual acuity of patients with progressive keratectasia following laser in situ keratomileusis (LASIK). METHODS Five eyes of four patients underwent penetrating keratoplasty for ectasia after LASIK: In one patient the second eye was operated on 10 months after the first keratoplasty. The pre- and postoperative refraction, best spectacle-corrected visual acuity, and topo...

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...

Objective. To report the rate of progression of keratectasia after primary crosslinking (CXL) and evaluate the safety and efficiency of CXL redo. Materials and Methods. We conducted a retrospective analysis of the patients who underwent CXL between 2010 and 2013 at the Beirut Eye Specialist Hospital, Lebanon. Progression of keratectasia was based on the presence of an increase in maximum kerato...

background: the aim of this prospective, randomized, single-blinded study was to compare the effects of a carbohydrate drink 400 ml given 2 h before the surgery with preoperative overnight fasting on the gastric ph and residual volume, postoperative nausea and vomiting (ponv) and antiemetic consumption in patients undergoing laparoscopic cholecystectomy. materials and methods: forty american so...

PURPOSE To evaluate the complication rate of corneal crosslinking (CXL) for primary keratectasia and to develop recommendations for avoiding complications. SETTING Institut für Refraktive und Ophthalmo-Chirurgie, Zurich, Switzerland. METHODS In a prospective study, eyes with verified progressive keratectasia had standard CXL. Preoperative and 6- and 12-month postoperative examinations inclu...

Progressive post-LASIK keratectasia (PPLK) is a progressive deformation of corneal anatomy that occurs rarely but may have severe consequences. Using the scientific literature and new hypotheses, we attempted to determine whether PPLK is a biomechanical result of laser in situ keratomileusis (LASIK), a chronic disease process affecting individuals predisposed to the condition, or a combination ...

in this paper, we discuss the present situation of laparoscopy in gynecology. there is no doubt that hospital stay, postoperative pain and convalescence are less when it is possible to treat gynecologic disease via laparoscopy. however, for reaching the final conclusion about the other effects of this kind of surgery, e.g., adhesion formation after operation, pregnancy rate, etc., a series of p...

Thin-flap laser in situ keratomileusis (LASIK) is a general term used to describe LASIK performed under intentionally created thin flaps of 130 μm thickness or less. Thinflap LASIK has been proven to be a safe, effective, and predictable procedure for myopic refractive corrections (1-6). It has the potential advantage of preserving more posterior corneal tissue available for laser ablation and ...
