PURPOSE To determine the clinical practicability of in vivo dynamic corneal imaging (DCI) to assess the individual elastic properties of normal human eyes, eyes with abnormal findings, and eyes after refractive surgery. SETTING University Eye Clinic, Paracelsus Private Medical University, Salzburg, Austria. METHODS The DCI method uses sagittal, stepwise, central indentation of the cornea wi...

Excimer lasers and high technology instrumentation have ushered in a new era of vision improvement surgery in Hawaii, replacing the more traditional forms of refractive surgery: cataract surgery, corneal transplant surgery, and radial keratotomy. Corneal surgery has been enhanced by new techniques of microsurgery and a more effective tissue procurement system for donor corneal tissue. Several l...

Purpose: To provide a summary of the most recent evidence-based data on the paediatric refractive surgery. Methods: A review of the published studies from 1990 to 2015 was undertaken with emphasis on recent articles from 2010 to 2015. Results: Searching Scopus and PubMed, using the keywords of refractive surgery, phakic, paediatric, IOL, children and amblyopia alone or in various combinations y...

PURPOSE To use optical coherence tomography (OCT) to measure corneal power and calculate intraocular lens (IOL) power in cataract surgeries after myopic and hyperopic laser vision correction (LVC). METHODS Patients with previous LVC were enrolled in this prospective study at two centers (Doheny Eye Institute, Los Angeles, CA, USA and Cullen Eye Institute, Houston, TX, USA). Corneal power was ...

Cataract surgery due to advances in small incision surgery evolved from a procedure concerned with the primary focus on the safe removal of cataractous lens to a procedure focused on the best possible postoperative refractive result. As the outcomes of cataract surgery became better, the use of lens surgery as a refractive modality in patients without cataracts has increased in interest and in ...

INTRODUCTION Apical protrusion in the central 4-mm ring in the Scheimflug imaging (Pentacam), both for the anterior and posterior floats as well as Corneal Hysteresis and Corneal Resistance Factor by Ocular Response Analyzer (ORA), generally are considered important predictors for post-Lasik ectasia. The aim of this work was to find out if there is a statistically significant correlation betwee...

AIM To assess superficial lamellar keratectomy augmented by excimer laser smoothening with sodium hyaluronate 0.25%, for the management of superficial corneal opacities. METHODS Consecutive procedure performed in 14 eyes (13 patients) with an automated microkeratome and excimer laser phototherapeutic keratectomy (PTK) smoothening using sodium hyaluronate 0.25%. MAIN OUTCOME MEASURES UCVA, B...

PURPOSE The aim of this study was to evaluate and report the visual, refractive and aberrometric outcomes of cataract surgery with implantation of the new aspheric Tecnis ZCT toric intraocular lens (IOL) in eyes with low to moderate corneal astigmatism. METHODS We conducted a prospective study of 19 consecutive eyes of 17 patients (mean age: 78 years) with a visually significant cataract and ...

PURPOSE To compare the efficacy of conventional laser in situ keratomileusis (LASIK) in treating corneal astigmatism and in treating noncorneal ocular residual astigmatism. SETTING Private practice, Nashville, Tennessee, USA. DESIGN Retrospective case series. METHODS The records of dominant eyes of consecutive patients who had LASIK were retrospectively analyzed to compare the efficacy of...
