Abstract

Purpose: To assess signs of dry eye syndrome in keratoconic eyes following intracorneal ring segment (ICRS) implantation. Patient and methods: Twenty eyes of 20 consecutive patients with keratoconus were assessed for tear film changes following ICRS implantation at 6 months postoperatively. Evaluated parameters included tear osmolarity, non-invasive tear breakup time test (NI-BUT test) and Schirmer test I and II before and after treatment. Results: No significant changes were found with respect to osmolarity, Schirmer I and II ( p = 0.9, p < 0.64, and p < 0.91, respectively). The NITUBT was significantly lower after surgery ( p = 0.04). Conclusion: Our results suggest that implantation of ICRS does not result in a significant change in tear film osmolarity, or tear film volume nor improves the tear film stability.
