Abstract. Purpose:To report the therapeutic effect of atelocollagen plug of lacrimal punctum(Keeptear®)for dry eye. Cases and Method:This prospective study was made on 89 eyes of 45 patients with dry eye that failed to respond to topical medication. The series comprised 25 male and 64 female eyes. The age averaged 75 years. Affected eyes were inserted with lacrimal punctum plug(Keeptear®)and were followed up for 6 months. Results:Subjective symptoms and all objective findings improved 2 weeks after insertion. Findings by Schirmer I method improved after 2 weeks only. Elongation of tear breakup time reached its peak 2 weeks after insertion. Improvement of subjective symptoms and findings by fluorescein staining lasted after presumed extrusion of the plug 2 months after insertion. Improvement of subjective symptoms lasted for 4 months as the median. Eight eyes(9%)developed transient lacrimation,eye discharge,or itchiness. Conclusion:Occlusion of lacrimal puncta using atelocollagen plug(Keeptear®)was safe and effective for dry eye.
