Dry Eye Treatment with Topical Cyclosporine 0.1% in Chondroitin Sulfate Ophthalmic Emulsion

Purpose: To evaluate the efficacy of topical cyclosporine 0.1% in chondroitin sulfate emulsion for the treatment of dry eye. Methods: This retrospective multicenter study included 100 eyes of 50 dry eye patients aged >= 18 years, with preoperative ocular surface disease index (OSDI) score >12 or corneal staining grade >1 (in either eye) who underwent dry eye treatment with topical cyclosporine 0.1% in chondroitin sulfate emulsion (Klarity-C, ImprimisRx) for 3 months. Postoperative evaluation included comparison of the changes in OSDI score and corneal staining grade after 3 months of treatment from baseline. Results: From baseline to 3 months, a statistically significant improvement in mean OSDI scores (38.19 vs 24.18, p <0.001) as well as mean corneal staining grade (3.62 vs 2.20, p <0.001) was observed. The proportion of subjects with severe dry eye decreased from 62% to 20% and more than one-third (34%) of patients were in the normal OSDI range. The percentage of eyes with corneal staining grade of 2 or 3 decreased from 21% (baseline) to 8% at 3 months; 50% of the eyes had corneal staining grade of 0. The treatment was found to be safe with no adverse events observed in the study. Conclusion: Dry eye treatment with twice daily cyclosporine 0.1% in chondroitin sulfate emulsion was found to be safe and effective in reducing signs and symptoms of dry eye.
