The purpose of this study was to compare the short-term changes in retina and choroidal tissue after femtosecond laser-assisted cataract surgery (FLACS) standard phacoemulsification (PE) surgery.In all, 25 eyes undergoing FLACS 27 PE were included nonrandomized, retrospective, cross-sectional study. Central retinal thickness (CRT) (CT) measured pre- postoperatively (at day 1, 1 week later, month) with spectral domain optical coherence tomography (OCT) all patients compared. For group...

Purpose To determine the safety of Laser SoftFit™ patient interface by comparing intraoperative results with contact LenSx® femtosecond laser platform (FSL). Methods In this nonrandomized, consecutive case series, 50 eyes underwent laser-assisted cataract surgery (FLACS) using (group 1); FLACS was performed in another eyes, 2). Intraoperative complications (corneal folds) and surgical (incomplete free capsulotomies, incomplete phacofragmentation, unopened incisions) were compared. Results...

Purpose To compare two different fragmentation patterns in femtosecond laser‐assisted cataract surgery (FLACS) terms of phaco values, postoperative endothelial cell count (ECC) and corneal thickness (CT). Methods This non‐randomized, retrospective cross‐sectional study included patients with senile grade 3 who underwent FLACS using the LenSx laser system. In Group 1 (32 eyes), lens was created as a cross pattern. 2 (35 hybrid Intraoperative measurements were procedure time, ultrasound (US)...

Purpose To evaluate efficacy and safety of contact lens-assisted corneal cross-linking (CACXL) among progressive keratoconus patients with thin corneas. Setting Private eye hospital Design Cross-sectional study Methods Thirty-six eyes 36 consecutive thinnest thickness 380–400 µm after epithelium removal were included. CACXL was performed based on use a dextran-free isotonic (>0.1%) riboflavin solution hydroxypropyl methylcellulose (HPMC, 1.1%) epithelial placement riboflavin-soaked lens...
