  Purpose
The purpose of this study was to determine the safety and retention times of two different lengths (10 mm and 20 mm) of the MINI MONOKA canicular stent when inserted in the eye for up to three months in subjects with or without dry eye.

Condition Intervention
Healthy Dry Eye Device: MINI MONOKA canalicular stent, 10 mm Device: MINI MONOKA canalicular stent, 20 mm

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Screening
Official Title: A Three-Month Safety Study to Determine the Retention Times of Side-Arm Canalicular Stents

Primary Outcome Measures:
  • Mean Retention Time [ Time Frame: From baseline (Day 0) up to Month 3 ]
    At all study visits the investigator conducted a slit lamp examination to determine whether the canalicular stent was present.


Secondary Outcome Measures:
  • Percentage of Subjects Retaining the Stent at Month 3 [ Time Frame: Month 3 ]
    At all study visits the investigator conducted a slit lamp examination to determine whether the canalicular stent was present.


Enrollment: 60
Study Start Date: October 2008
Study Completion Date: February 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Canalicular stent, 10 mm
MINI MONOKA canalicular stent (tube), 10 mm, inserted in the lower lacrimal canaliculus (tear duct) of one eye for up to 3 months
Device: MINI MONOKA canalicular stent, 10 mm
40 mm hollow intubation stent composed of a silicon tube and an oval collarette head (plug), cut to 10 mm length
Other Name: MINI MONOKA
Experimental: Canalicular stent, 20 mm
MINI MONOKA canalicular stent (tube), 20 mm, inserted in the lower lacrimal canaliculus (tear duct) of one eye for up to 3 months
Device: MINI MONOKA canalicular stent, 20 mm
40 mm hollow intubation stent composed of a silicon tube and an oval collarette head (plug), cut to 20 mm length
Other Name: MINI MONOKA

Detailed Description:
This study consisted of 6 visits conducted over a period of 3 months. At Visit 1 (Day 0), the canalicular stent was inserted. If the stent insertion failed, the subject was rescheduled for insertion at the Day 2 visit. If the stent insertion was not successfully completed by the end of the Day 2 visit, the subject was discontinued from the study. Any subject who had the stent inserted but lost the stent (noticed or unnoticed) after the Day 2 Visit was considered to have completed the study.
