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.

The Influence of Tear Film Quality on Visual Function.

Background: The prevalence of dry eye disease (DED) is increasing globally, resulting in a variety of eye symptoms characterized by discomfort and visual disturbances. The accurate diagnosis of the disease is often challenging and complex, requiring specialized diagnostic tools. This study aimed to investigate the impact of tear film instability on visual function and to evaluate the value of post-blink blur time (PBBT) as an alternative method for assessing tear film stability.

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.
