1. A method of treating a patient with Open Angle Glaucoma (OAG) or Ocular Hypertension (OH) in an eye, comprising:
- providing a unit dosage of a prostaglandin analog to an eye over a treatment period, wherein the prostaglandin analog is administered from a lacrimal implant comprising a sustained release formulation and the prostaglandin analog is released in a therapeutically effective dose from the lacrimal implant over the treatment period,wherein the lacrimal implant is inserted into a lower punctum and a blank lacrimal implant that does not comprise a therapeutic agent is inserted in an upper punctum;
or the lacrimal implant is inserted into an upper punctum and a blank lacrimal implant that does not comprise a therapeutic agent is inserted in a lower punctum; and
,wherein the lacrimal implant comprises a first member defining a first axis and having a first end along the first axis;
a second member defining a second axis and having a second end along the second axis; and
a third member connecting the first end of the first member and the second end of the second member at a first angle to form an angled intersection and wherein the third member of the lacrimal implant having an upper surface, and further comprising a bore defining a third axis and a second angle, wherein the first angle is defined by the first axis with respect to the second axis, the second angle is defined by the first axis with respect to the third axis, and the bore is configured to be accessible to an insertion tool for facilitating insertion of the implant and wherein the bore extends from the upper surface into the third member.

Abstract
A method of decreasing intraocular pressure (IOP) in an eye of a patient in need thereof includes implanting a first lacrimal implant through an upper punctum and into an upper lacrimal canaliculus of the eye of the patient. The method may further comprise implanting a second lacrimal implant through a lower punctum and into a lower lacrimal canaliculus of the eye of the patient, and releasing, on a sustained basis a therapeutically effective amount of an intraocular pressure-reducing therapeutic agent.

10. A method of treating a patient with Open Angle Glaucoma (OAG) or Ocular Hypertension (OH) in an eye by reducing intraocular pressure (TOP) in the eye, comprising:
-
providing a unit dosage of a prostaglandin analog to an eye over a treatment period of at least 4 weeks, wherein the prostaglandin analog is administered from a lacrimal implant comprising a sustained release formulation and the prostaglandin analog is released in a therapeutically effective dose from the lacrimal implant over the treatment period of at least 4 weeks, wherein the lacrimal implant is inserted into a lower punctum and a blank lacrimal implant that does not comprise a therapeutic agent is inserted in an upper punctum;
or the lacrimal implant is inserted into an upper punctum and a blank lacrimal implant that does not comprise a therapeutic agent is inserted in a lower punctum; and
,wherein the lacrimal implant comprises a first member defining a first axis and having a first end along the first axis;
a second member defining a second axis and having a second end along the second axis; and
a third member connecting the first end of the first member and the second end of the second member at a first angle to form an angled intersection and wherein the third member of the lacrimal implant having an upper surface, and further comprising a bore defining a third axis and a second angle, wherein the first angle is defined by the first axis with respect to the second axis, the second angle is defined by the first axis with respect to the third axis, and the bore is configured to be accessible to an insertion tool for facilitating insertion of the implant and wherein the bore extends from the upper surface into the third member. - View Dependent Claims (11, 12, 13)

14. A method of treating a patient with Open Angle Glaucoma (OAG) or Ocular Hypertension (OH) in an eye by reducing intraocular pressure (TOP) in the eye, comprising:
-
a) measuring the TOP of the patient to obtain a baseline TOP before treatment; b) providing a unit dosage of a prostaglandin analog as a sustained release formulation; c) delivering the sustained release formulation to the eye using a lacrimal implant comprising the sustained release formulation; and d) releasing the prostaglandin analog to the eye on a sustained basis over at least 8 weeks, wherein the lacrimal implant is inserted into a lower punctum and a blank lacrimal implant that does not comprise a therapeutic agent is inserted in an upper punctum;
or the lacrimal implant is inserted into an upper punctum and a blank lacrimal implant that does not comprise a therapeutic agent is inserted in a lower punctum,wherein the lacrimal implant comprises a first member defining a first axis and having a first end along the first axis;
a second member defining a second axis and having a second end along the second axis; and
a third member connecting the first end of the first member and the second end of the second member at a first angle to form an angled intersection and wherein the third member of the lacrimal implant having an upper surface, and further comprising a bore defining a third axis and a second angle, wherein the first angle is defined by the first axis with respect to the second axis, the second angle is defined by the first axis with respect to the third axis, and the bore is configured to be accessible to an insertion tool for facilitating insertion of the implant and wherein the bore extends from the upper surface into the third member. - View Dependent Claims (15, 16, 17, 18, 19, 20)
