PURPOSE: The purpose of this study was to compare the central corneal thickness (CCT) measurements of four noncontact devices in healthy eyes. MATERIALS AND METHODS: In a sample of 45 healthy controls, CCT was measured using an optical biometer (IOLMaster 700) based on swept-source optical coherence tomography (SS-OCT), high-resolution rotating Scheimpflug camera system (Pentacam HR), spectral-domain OCT (SD-OCT) device with an anterior segment module (Spectralis), and noncontact pachymetry (NCP) device (Topcon TRK-2P)...

PURPOSE: To compare the outcomes and complications of topical difluprednate 0.05% and loteprednol gel 0.5% after routine cataract surgery. METHODS: Subjects received either difluprednate emulsion 0.05% (n=30 eyes) or loteprednol gel 0.5% (n=30 eyes) after routine cataract surgery. Topical steroid drops were initiated 3 days before cataract surgery and continued for 2 weeks postoperatively. Anterior chamber (AC) cell grade, corneal edema, corneal pachymetry, visual acuity, ocular surface quality (Oxford scale), and intraocular pressure (IOP) were evaluated at 1 day, 1 week, and 1 month postoperatively...

The management of severe keratoconus requires corneal transplantation, for which the gold standard is deep anterior lamellar keratoplasty (DALK), preserving the healthy Descemet's membrane and endothelium. The safety and reproducibility of corneal cuts have been improved by the evolution of femtosecond lasers in refractive surgery, and femtosecond laser in DALK would seem to provide the same advantages over the manual method. In our retrospective study, we compare functional and anatomical results of femtosecond-assisted DALK versus manual trephination DALK in patients with keratoconus in stage 4 of the Krumeich classification...

PURPOSE: To present a case series of patients with subclinical keratoconus with normal topometric (anterior curvature) and tomographic findings in one eye who showed abnormalities detected by Corvis ST (Oculus Optikgeräte GmbH, Wetzlar, Germany) in vivo biomechanical assessment. METHODS: All patients had a complete ophthalmic examination, including the Corvis ST biomechanical measurements, optical tomography, and pachymetry with Pentacam (Oculus Optikgeräte GmbH), and Placido-based topography with either the Nidek (OPD III Nidek, Gamagori, Japan) or CSO platform (Costruzione Strumenti Oftalmici, Florence, Italy)...

Tonometry is a fundamental procedure in routine ophthalmologic examination. Although regarded as the reference standard, the Goldmann applanation tonometer (GAT) has its limitations. A new portable alternative to the GAT is the iCare rebound tonometer (RT). The aim of the present study was to compare the intraocular pressure (IOP) results obtained using the RT and GAT and then correlate the results with the central corneal thickness (CCT). Moreover, the tolerability and safety of the RT were evaluated. The IOP of 336 patients (672 eyes) was determined by the RT and GAT...

PURPOSE: To assess intra-observer reproducibility and repeatability of corneal pachymetry measurements with RTVue XR-100 anterior segment optical coherence tomography (AS-OCT) in normal cornea. METHODS: Eighty-four eyes of 84 healthy volunteers were enrolled for this study. A single examiner performed 3 successive corneal pachymetry mappings with RTVue XR-100 AS -OCT in a single session. One eye was randomly selected for the analysis. Intrasession intraexaminer reproducibility and repeatability were calculated for the minimum corneal thickness (MCT), central corneal thickness (CCT, central 0-2 mm), pericentral (2-5 mm) and peripheral (5-6 mm) annular zones of cornea, in the pachymetry mapping protocol by intraclass correlation coefficient (ICC), coefficient of variation and test retest variability...

Purpose. To evaluate changes in anterior, posterior, and total corneal astigmatism in patients after Descemet membrane endothelial keratoplasty (DMEK). Methods. We retrospectively included 29 eyes of 23 patients (age 67.6 ± 9.8 years, 13 female, 10 male) after DMEK surgery. The magnitude and axis orientation of anterior, posterior, and total corneal astigmatism before and after DMEK were determined using a rotating Scheimpflug system (Pentacam HR, Oculus). Results. The magnitude of anterior, posterior, and total corneal astigmatism in the central cornea did not change significantly after surgery...

PURPOSE: The aim of this study is to report surgical outcomes in patients undergoing phacoemulsification surgery (PE) with versus without ophthalmic viscosurgical devices (OVDs). METHODS: This is a comparative case series study. In total, 145 patients who performed PE with OVDs in 68 eyes (Group 1) and without OVD in 77 eyes (Group 2) were enrolled. A comprehensive ophthalmological examination was performed including slit-lamp, fundus examination. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) specular endothelial microscopy (SM), and ultrasound pachymetry (UP) were also measured before surgery and at four-time points postoperatively...

INTRODUCTION: Descemet's membrane endothelial keratoplasty (DMEK) can replace just the corneal endothelium and respect the natural corneal anatomy. Currently, the technique of endothelial graft preparation remains manual and non-standardized. PURPOSE: To report anatomic and functional results after DMEK, and compare two techniques of graft preparation. METHODS: Single-center retrospective study, including 64 eyes of 64 patients undergoing DMEK, from September 2014 to February 2016 at Clermont-Ferrand University Medical Center...

PURPOSE: To assess the clinical outcome after successful rebubbling procedures for visually significant graft detachment after Descemet membrane endothelial keratoplasty (DMEK). METHODS: From a total of 760 consecutive DMEK surgeries, 41 eyes required rebubbling. Of those, 33 eyes of 31 patients were successful and were included in our retrospective outcome analysis study. Main outcome measures were compared with those of matched controls with uneventful primary DMEK (attached DMEK grafts without rebubbling)...
