Moderate to Severe Dry Eye Clinical Trial
Official title:
The Retention Rate Between Superflex Punctal Plugs, and Parasol Punctal Occluders
The purpose of this study is to determine if Parasol punctal occluders (Brand A) have a higher rate of retention than Superflex punctal plugs (Brand B).
Eyes will be randomized to either Brand A or Brand B punctal plug. The primary outcome measure is length of time punctual plugs are retained, measured in weeks. This will be measured at weekly assessments for 6 months. Secondary outcome measures include patient satisfaction, and improvement in subjective and objective dry eye scores, as well as complications related to punctual plugs including spontaneous plug loss, and intolerance. We will evaluate these measures by repeating the Canadian Dry Eye Assessment, Schirmer 1, tear meniscus height, fluorescein corneal staining (NEI scale), and lissamine green conjunctival staining (NEI scale) at month 1, month 3, and month 6 visits. ;
