Purpose: To assess clinical outcomes of corneal cross-linking (CXL) intervention in a population diagnosed with progressive keratoconus.
Methods: This single-center retrospective cohort study included consecutive patients who underwent standard CXL or accelerated CXL for progressive keratoconus at a major teaching hospital in southern Israel between January 2015 and December 2019. Patients' medical files were reviewed, and pre-operative and post-operative data regarding demographics and clinical and tomographic characteristics were extracted and analyzed.
Introduction: Keratoconus is a progressive corneal disease commonly treated by collagen cross-linking (CXL). Accelerated protocols have recently become common. This study sought to compare the outcomes of accelerated and standard CXL in terms of visual acuity, keratometry, and tomographic parameters in pediatric population.

Methods: Patients who underwent A-CXL and A-CACXL due to progressive keratoconus were enrolled from January 2015 to January 2018 in this retrospective case-control study. The treatment group (minimum corneal thickness of less than 400 µm after epithelium removal; 30 patients, 30 eyes) was treated with A-CACXL; the control group (minimum corneal thickness of 400 µm or greater, 32 patients, 32 eyes) was treated with A-CXL.

Article Synopsis
- The study aimed to investigate how estrogen and progesterone impact the biomechanical properties of porcine corneas by measuring central corneal thickness (CCT) and tissue stiffness.* -
- Thirty porcine corneas were tested: one group with estrogen, another with progesterone, and a control group, revealing that estrogen significantly reduced corneal stiffness while progesterone had no notable effect.* -
- Overall, estrogen made the corneas less stiff without affecting their thickness, while progesterone showed no significant changes in either thickness or stiffness.*
Purpose: To evaluate the safety and efficacy of accelerated contact lens-assisted cross-linking (A-CACXL) for patients with keratoconus and thin corneas.
Methods: This retrospective study included consecutive patients undergoing A-CACXL for progressive keratoconus from 2015 to 2017. Patients with a minimum corneal thickness of 400 µm or less after epithelium removal who underwent A-CACXL (9 mW/cm for 10 minutes, using iso-osmolar 0.
