PURPOSE To assess the long-range outcomes of photorefractive keratectomy (PRK) using functional and topographic criteria in myopic eyes with suspected keratoconus. SETTING Rothschild Foundation, Paris, France. DESIGN Retrospective interventional case series. METHODS Eyes of patients classified as keratoconus suspects or keratoconus by the Corneal Navigator software of the OPD-Scan II devi...

PURPOSE To compare the accuracy of central true net corneal power (cTNP) and mean true net corneal power (mTNP) of the Pentacam system to give a keratometry (K) reading for calculating IOL (intraocular lens) power in eyes following refractive surgery. METHODS Refraction, an automated K-reading (Km), cTNP and mTNP were measured for 15 eyes that required cataract surgery and had previously unde...

Purpose The purpose of this study was to assess the safety and efficacy of femtosecond laser-assisted Keraring implantation followed by transepithelial accelerated corneal collagen cross-linking (CXL) for the treatment of keratoconus in children with vernal keratoconjunctivitis (VKC). Study design This is a prospective interventional non-comparative case series. Patients and methods Eightee...

AIM To evaluate the clinical outcomes after Ferrara intrastromal corneal ring segments (ICRS) reoperation in patients with keratoconus. METHODS A total of 37 keratoconus eyes implanted with intrastromal corneal ring segments, which had an ICRS exchange, addition, reposition or removal were evaluated. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), keratometry (K), asphe...

PURPOSE To describe the technique and outcomes of limbal stem cell-sparing lamellar keratoplasty (LSCS-LKP) for the management of advanced keratoglobus (KGB). METHODS In a sequential interventional case series from March 2010 to December 2012, 8 eyes of 6 patients with advanced KGB underwent an LSCS-LKP. Three patients had isolated KGB, 2 were affected with the Ehlers-Danlos syndrome, and the...

PURPOSE To evaluate the safety and efficacy of corneal collagen crosslinking (CXL) using a transepithelial technique to treat keratoconus. SETTING Cornea and refractive surgery subspecialty practice. DESIGN Prospective clinical trial. METHODS Transepithelial CXL was performed in eyes with keratoconus using proparacaine with benzalkonium chloride (BAK) 0.01% to facilitate riboflavin absorp...

Purpose To describe the case of a patient developing corneal ectasia following LASIK for the correction of myopic astigmatism. Materials and Methods A 39-year-old man underwent bilateral uneventful LASIK for myopic astigmatism of -10.25 -1.75 ×040 OD and -8.00 -2.50 ×005 OS. Preoperative corneal pachymetry was 542 micrometers OD and 543 micrometers OS. Preoperative corneal topography showed b...

Purpose: To evaluate the efficacy of the combined treatment of Intacs SK (Severe keratoconus) and corneal collagen crosslinking in the management of advanced keratoconus (KC). Setting: Private laser center, Haifa, Israel. Affiliated to Hadassah Hospital, Jerusalem. Methods: This is a retrospective study. Intacs SK were implanted using manual technique in eyes with moderate-tosevere keratoconus ...

This study was aimed to assess the predictability of intraocular lens (IOL) power calculation after simultaneous pterygium excision and phacoemulsification with IOL implantation. We retrospectively reviewed the clinical charts of 60 eyes of 60 consecutive patients (mean age ± standard deviation, 73.5 ± 7.0 years) who developed pterygium and cataract. We determined visual acuity (logMAR), manife...

PURPOSE To assess subjective visual function after corneal collagen crosslinking (CXL). SETTING Cornea and refractive surgery subspecialty practice. DESIGN Prospective randomized controlled clinical trial. METHODS Patients completed a subjective questionnaire regarding visual symptoms administered preoperatively and 1 year after CXL. Patients ranked self-reported symptoms of photophobia, ...
