The Impact of Standard Cross-Linking on the Corneal Optical Density-Age Relationship in Keratoconus After Mechanical Stripping of the Epithelium.

To determine if cross-linking (CXL) treatment modifies any pre-existing association between corneal optical density (COD) and age in keratoconus free of corneal scarring. COD was monitored in two groups (i) before and after standard CXL treatment for keratoconus (de-epithelization with a crescent blade,  = 69 eyes) and (ii) age/gender-matched cases without any signs of keratoconus ( = 24 eyes). Seven different markers of COD were quantified using a 0-100 grey scale, supplied with Pentacam™ software.

Comparative Analysis of the Clinical Outcomes of Two Toric Presbyopia-Correcting Intraocular Lenses.

Introduction: To evaluate and compare the clinical outcomes of two toric presbyopia-correcting intraocular lenses (IOLs).

Methods: Non-randomized prospective comparative study including 86 eyes of 51 patients (age 43-83 years) that underwent cataract surgery with implantation of one of the following two IOLs: TECNIS Toric Synergy (Johnson & Johnson Vision) (Synergy group) or AT LISA tri toric 939MP (Carl Zeiss Meditec) (ATLISA group). Visual and refractive outcomes were evaluated during a 6-month follow-up.

Predictability of the Achieved Lenticule Thickness in Keratorefractive Lenticule Extraction for Myopia Correction.

Purpose: To assess the predictability between the SCHWIND ATOS femtosecond laser (SCHWIND eye-tech-solutions) read-out and achieved lenticule thickness measured using MS-39 anterior segment optical coherence tomography (ASOCT; CSO) at the corneal vertex at postoperative 1 day and 1 and 3 months of follow-up.

Methods: This retrospective case series included 130 eyes of 65 consecutive patients who were treated with SmartSight (SCHWIND eye-tech-solutions) lenticule extraction. Sixty-four percent of patients were women with a mean spherical refraction of -4.

First European results of a new refractive lenticular extraction procedure-SmartSight by SCHWIND eye-tech-solutions.

Background: To evaluate vision 3 months after SmartSight lenticule extraction treatments.

Design: Case series.

Methods: This case series of patients were treated at Specialty Eye Hospital Svjetlost in Zagreb, Croatia.

Comparison between the change in total corneal astigmatism and actual change in refractive astigmatism in transepithelial photorefractive keratectomy (tPRK), laser in situ keratomileusis (LASIK) and femtosecond laser assisted laser in situ keratomileusis (FsLASIK).

Purpose: To compare changes in astigmatism by refraction and total corneal astigmatism after tPRK, LASIK and FsLASIK.

Setting: Specialty Eye Hospital Svjetlost, Zagreb, Croatia.

Design: Partially masked, semi-randomized, prospective, case-by-case, interventional, clinical study.

A critical evaluation of longitudinal changes of astigmatism following implantation of toric implantable collamer lens (TICL): a comparison between treated and untreated cases over 4 years.

Purpose: To evaluate residual astigmatism following correction with toric implantable collamer lens (TICL) (group I) over a period of 4 years and compare with the change of astigmatism in spectacle wearers (group II).

Methods: Groups I (86 cases implanted with TICL [EVO + Visian ICL, Staar Surgical, Nidau, Switzeland], preop refractive error [sphere and cylinder] - 22.25 DS to - 1.

Clinical Outcomes With a New Continuous Range of Vision Presbyopia-Correcting Intraocular Lens.

Purpose: To evaluate the clinical outcomes including patient-reported outcome measures in a sample of eyes undergoing bilateral cataract surgery with implantation of a new model of presbyopia-correcting intraocular lens (IOL).

Methods: This non-randomized prospective case series enrolled 206 eyes of 103 patients undergoing phacoemulsification cataract surgery with bilateral implantation of the TECNIS Synergy IOL (Johnson & Johnson Vision). High and low contrast visual acuity, refractive, defocus curve, and patient-reported visual performance (Catquest-9SF questionnaire) outcomes were evaluated during a 3-month follow-up.

Predicted and Measured Changes in Posterior Corneal Astigmatism after Uncomplicated Femtosecond Assisted LASIK (FsLASIK) and Microkeratome LASIK Correction for Myopia and Low Astigmatism.

: To compare predicted and measured changes in astigmatism at the posterior corneal surface (PCS) after FsLASIK or LASIK.: Astigmatism was measured at both corneal surfaces (Pentacam) before and 3 months after unremarkable FFsLASIK (roup 1,n = 100) or LLASIK (roup 2,n = 100) for myopia (-7.25DS to -0.

Vector Analysis of Visual Acuity and Refractive Outcomes of Astigmatic Corrections After T-PRK and Fs-LASIK.

Introduction: T Transepithelial photorefractive keratectomy (T-PRK) and femtosecond laser in situ keratomileusis (Fs-LASIK) are reftactive surgery methods for treating myopia and myopic astigmatism. Although T-PRK obtains similar results to Fs-LASIK with spherical myopia, it has differences in astigmatism correction. Vector analysis is a perfect tool to see the real difference between these two methods regarding astigmatic refraction and visual acuity.

Enlarged Foveal Avascular Zone after Whiplash Injury-Acquired Berlin's Edema.

We describe a case of optical coherence tomography angiography (OCTA) changes in the foveal avascular zone (FAZ) in a patient that had suffered Berlin's edema after a whiplash neck injury. The patient reported central scotoma throughout the 1-year follow-up, confirmed by visual field examination. OCTA showed FAZ enlargement of the left eye as compared to the healthy right eye in the superficial capillary layer and even more in the deep capillary layer.

Pachymetry and Elevation Back Map Changes in Keratoconus Patients After Crosslinking Procedure.

Introduction: The crosslinking (CXL) procedure using the standard Dresden protocol is established as the gold standard for the treatment of progressive keratoconus.

Aim: The aim of this paper is to correlate the pachymetry and elevation back map (EBM) changes in the period from 3 to12 months of keratoconus patients after the CXL procedure. M.
