OBJECTIVES: Here, our aim was to report our treatment strategies and their results performed for visual rehabilitation after penetrating keratoplasty. MATERIALS AND METHODS: The medical records of 98 patients (54 male/44 female), with results from 104 eyes, who underwent penetrating keratoplasty between January 2013 and January 2015 at the Baskent University Faculty of Medicine, Department of Ophthalmology were reviewed. Patient age, indication for penetrating keratoplasty, interventions performed for visual rehabilitation, follow-up duration, topographic and refractive astigmatism at the end of follow-up, and final best corrected visual acuity results were recorded...

AIM: To evaluate the visual and topographic outcomes of a two-stage approach treatment for selected cases of progressive keratoconus (KC); corneal collagen cross-linking (CXL) followed by phacoemulsification with toric intraocular lens (IOL) implantation. METHODS: The study included 9 eyes of 6 patients diagnosed with progressive KC, aged from 35 to 47 years (41.6±11.2 years). All studied eyes underwent a two-stage approach treatment: first corneal collagen CXL followed after at least 6 months by phacoemulsification with foldable toric IOL implantation in both eyes of three patients and only one eye of the other three patients...

PURPOSE: To measure posterior corneal astigmatism (PCA) and investigate its influence on total corneal astigmatism (TCA) in eyes with keratoconus. METHODS: Keratometric astigmatism (KA), PCA, and TCA were investigated by means of a dual Scheimpflug analyzer in patients with keratoconus. Vector analysis was carried out with the Næser polar value method. RESULTS: We enrolled 119 eyes. PCA magnitude averaged 0.77 ± 0.43 diopters (D) and exceeded 0...

PURPOSE: To describe the results of cataract extraction with toric intraocular lens (IOL) implantation in patients with preexisting astigmatism from three corneal conditions (keratoconus, postkeratoplasty, and postpterygium surgery). METHODS: Cataract patients with topographically stable, fairly regular (although sometimes very high) corneal astigmatism underwent phacoemulsification with implantation of a toric IOL (Zeiss AT TORBI 709, Alcon Acrysof IQ toric SN6AT, AMO Tecnis ZCT)...

PURPOSE: To assess the changes in astigmatism and higher-order aberrations (HOAs) after toric intraocular lens (IOL) implantation for mild non-progressive keratoconus with cataract. METHODS: We prospectively examined 19 eyes of 19 consecutive keratoconic patients (mean age ± standard deviation, 63.1 ± 9.1 years) who underwent phacoemulsification with toric IOL implantation. We determined uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive astigmatism, corneal astigmatism, corneal HOAs and astigmatic axis rotation both preoperatively and 3 months postoperatively...

REVIEW
David M Poulsen, Joann J Kang
PURPOSE OF REVIEW: To review the recent advances and reported outcomes in the use of intrastromal corneal ring segments (ICRS) for the treatment of corneal ectasia. RECENT FINDINGS: ICRS are a well-tolerated and effective treatment for patients with corneal ectasia, particularly keratoconus, offering long-term improvement in visual, refractive, and keratometric measures. ICRS do not consistently decrease corneal aberrations. Patients with mild-to-moderate keratoconus, known to have less predictable outcomes with ICRS, may be better selected and treated with the use of customized nomograms, accounting for factors such as internal astigmatism...

PURPOSE: To evaluate the reproducibility of different Scheimpflug imaging-derived reference bodies in normal, keratoconus (KC), and crosslinked (CXL) eyes. METHODS: In this prospective, observational study, 40 participants populated the control group (CG), while 33 and 34 patients formed the KC group and the CXL group, respectively. One eye was randomly selected when both were eligible. Elevation measurements were obtained using Scheimpflug camera, by applying the following reference bodies: the best fit sphere (BFS), the best fit toric ellipsoid (BFTE), the best fit toric ellipsoid with fixed eccentricity of 0...

PURPOSE: To evaluate the results of using AcrySof toric intraocular lenses (IOLs) in the cataract surgery of patients with keratoconus (KCN). METHODS: In this study, 23 eyes of 17 patients with KCN who underwent cataract surgery using the toric IOL were evaluated. The amount and axis of the corneal astigmatism were measured by manual keratometry, corneal topography, refractive map of the Pentacam, and equivalent K reading of the Pentacam in all patients. RESULTS: The mean uncorrected visual acuity increased significantly 3 months after the surgery (P<0...

AIM: To assess the clinical outcomes following the use of toric implantable collamer lenses (toric ICL, STAAR Surgical) for the correction of high myopic astigmatism with keratoconus. METHODS: This retrospective study evaluated 21 eyes of 11 patients with spherical equivalents of -9.70±2.33 D (mean±SD) and astigmatism of -3.21±1.56 D who underwent toric ICL implantation for keratoconus. Preoperatively, and at 1, 3 and 6 months and 1, 2 and 3 years postoperatively, we assessed the safety, efficacy, predictability, stability and adverse events of the surgery...

We report a case of 18-year-old male who has undergone phacoemulsification with implantation of toric IOL (AcrySof IQ SN6AT9) after fixation of lens capsule with Cionni's capsular tension ring (CTR) for subluxated traumatic cataract with high astigmatism after deep anterior lamellar keratoplasty (DALK). He underwent right eye DALK for advanced keratoconus four years earlier.

PURPOSE: To assess the feasibility of fitting a lathed soft toric contact lens (STCL) after the implant of intrastromal corneal ring segments (ICRSs) to treat keratoconus. METHODS: Six months after ICRS implantation, 47 eyes of 47 patients (18-45 years) were fitted with a STCL. In each eye, we determined refractive error, uncorrected (UDVA) and corrected distance visual acuity (CDVA), and keratometry and asphericity measures. The outcome of STCL fitting was defined according to CDVA as successful (≤0...

A 50 year old man presented to Eye clinic University clinical centre Tuzla with bilateral visual impairment. Clinical examination revealed low visual acuity and keratoconus in both eyes, white cataract in right eye and diabetic retinopathy in left eye. Ultrasonography examination was normal. The patient underwent Trypan blue capsule staining, phacoemulsification and implantation of intraocular lens Alcon AcrySof SN60T9 16 D spherical and 6.0 D cylinder power. Phacoemulsification went uneventful and early postoperative recovery was successful...

PURPOSE: To evaluate the contribution of reference bodies for elevation maps in diagnosis of keratoconus (KC) and forme fruste keratoconus (FFK). METHODS: Study groups included (1) 80 eyes with KC, (2) 55 eyes with FFK, and (3) 95 eyes as control eyes. The maximum elevation value at the central 5 mm of the posterior cornea (MEL) and the elevation value at thinnest corneal point (TEL) were evaluated for their diagnostic capacity using receiver operating characteristic curves under the following reference bodies: sphere, ellipsoid, toric ellipsoid, and torus, with autodiameter and fixed 8-mm-diameter settings...

PURPOSE: To describe the results of multifocal toric intraocular lens implantation in two patients (one with forme fruste keratoconus and the other with frank but stable keratoconus). METHODS: A 50-year-old woman with forme fruste keratoconus and positive family history of keratoconus and a 42-year-old man with frank keratoconus underwent corneal collagen cross-linking. Uncorrected distance visual acuity was 20/800 in the right eye and 20/400 in the left eye and 20/400 in the right eye and 20/100 in the left eye, respectively...

PURPOSE: To evaluate the efficacy and safety of keratoconus refractive and visual improvement by combined intracorneal ring segments (ICRS; Intacs/Intacs SK, Addition Technology Inc., Des Moines, IL) and phakic intraocular lens (PIOL; Artisan/Artiflex Toric IOL, Ophtec BV, Groningen, Holland) implantation. METHODS: This study comprised patients who had ICRS implantation followed by PIOL implantation 6 or more months later for the correction of keratoconus. Over a 12-month follow-up after PIOL implantation, the main outcome measures were uncorrected and corrected distance visual acuity (UDVA and CDVA), spherical equivalent refraction, and central endothelial cell density...
