Evaluation of a Novel Ocular Lubricating Eye Drop (DRAGON)
The objective of this 2-part study is to assess the safety and tolerability of the new ocular lubricating drop ABR2 during short-term use in subjects for the temporary relief of ocular discomfort due to dryness of the eye.
In Part 1, participant will receive 1 drop of ABR2 in one eye and through assessments over a 1-hour period.
In Part 2, participant will use 1 drop of ABR2 at least two times a day for 28-day period (may use up to 4 times a day as needed) This is a single arm, open label study with no placebo or comparative arm.
