Dry eye complaints occur in 5.5 to 33.7% of the population, and are ranked as the most frequent symptoms of patients visiting ophthalmologists. Dry eye syndrome is caused by the reduced production and/or improper quality of the tear film. One of the causes of reduced tear production is Sjögren's syndrome. Sjögren's is estimated to affect up to 4 million patients in the US alone. It affects mostly middle aged women (40-50 years of age) with a female to male prevalence ratio of 9:1. The current study seeks to evaluate the safety and efficacy of LO2A ophthalmic solution in the symptomatic treatment of dry eye in patients with Sjögren's syndrome. This study will be conducted in compliance with the protocol, GCP,and applicable regulatory requirements.

| Primary | Change in corneal / conjunctival staining score using the National Eye Institute/Industry(NEI) Industry Grading System | NEI/Industry Workshop Conjunctival Staining Grading System. Devitalized epithelial cells of the bulbar conjunctiva are stained with lissamine green and can graded across six zones The scores for each zone (0-3) are summed to obtain an overall score for each eye (0-18.( The higher the results, the more severe the dryness of the eye. | 3 months form the basline | |
| Secondary | Change in Ocular Surface Disease Index (OSDI) questionnaire score. | The OSDI is assessed on a scale of 0 to 100, with higher scores representing greater disability. The index demonstrates sensitivity and specificity in distinguishing between normal subjects and patients with dry eye disease. | 1 and 3 months from the basline visit | |
