Purpose

This study investigates the structural changes in corneal layers and thickness in patients undergoing EndoArt implantation, utilizing in-vivo confocal microscopy (IVCM) for a detailed pre- and post-operative evaluation. IVCM provides high-resolution imaging of corneal layers, enabling quantitative assessments of endothelial cell density and corneal thickness, as well as qualitative analysis of morphological changes. Additionally, sub-basal nerve plexus imaging allows for the evaluation of nerve regeneration post-surgery. This study aims to provide insights into corneal healing dynamics, structural recovery, and corneal health outcomes over six months following EndoArt implantation.

 

Setting

This series of cases was managed and documented at the Ophthalmology Department of Hanusch Hospital in Vienna, utilizing IVCM to monitor pre- and post-operative changes in four patients.

Methods

To evaluate corneal layer changes and thickness in patients treated with EndoArt, four patients were recruited, and both AS-OCT and IVCM were performed preoperatively, as well as three and six months postoperatively. AS-OCT was performed using the MS-39 (Schwind), and IVCM was performed using the Heidelberg HRT3-RCM.

Results

AS-OCT and IVCM provided complementary postoperative findings. AS-OCT revealed a reduction in stromal thickness by the six-month follow-up, while IVCM demonstrated a progressive decrease in corneal edema, enhancing the visualization of cellular structures. The epithelial layer showed signs of regeneration, and keratocytes within the corneal stroma became increasingly distinguishable, aligning with clinical improvements.

Furthermore, IVCM detected changes in sub-basal nerve density, with gradual nerve regeneration observed both three and six months postoperatively. The superficial epithelium exhibited a resolution of epithelial bullae, which were replaced by a hyperreflective area bordered by adjacent epithelial cells.

Conclusions

The combination of AS-OCT and IVCM provided a comprehensive evaluation of corneal layer dynamics over six months following EndoArt implantation. The results highlight transient changes in stromal thickness and a gradual recovery of the endothelium and nerve layers throughout the postoperative period. These findings underscore the value of IVCM as a powerful tool for assessing structural corneal changes and monitoring the healing process after EndoArt treatment.
