Primary Outcome Measures:
  • IOP change from baseline and the primary analysis time point will be the IOP assessment at Week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 120
Study Start Date: December 2013
Estimated Primary Completion Date: June 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group A. L-PPDS single occlusion
Latanoprost Punctal Plug Delivery System (L-PPDS) continuous single occlusion; L-PPDS will be inserted in the lower punctum and no plug will be inserted in the upper punctum of each eye; L-PPDS will remain for a period of 14 weeks.
Drug: Latanoprost Punctal Plug Delivery System (L-PPDS)
Latanoprost Punctal Plug Delivery System (L-PPDS)
Experimental: Group B. L-PPDS double occlusion
Latanoprost Punctal Plug Delivery System (L-PPDS) continuous double occlusion; L-PPDS will be inserted in the lower punctum and non-therapeutic (NT) plug will be inserted in the upper punctum of each eye and both will remain for a period of 14 weeks.

  8. Subject with structural lid abnormalities (i.e., ectropion, entropion) in study eye
  9. Subject with an active lid disease in either eye (i.e., moderate or severe blepharitis, meibomianitis) that requires medical treatment
