1. An ocular medical implant comprising:
a substantially wedge-shaped body having a height and a width;
wherein the body further includes a first end having a first cross section having a first cross-sectional dimension in the width direction, a second end having a second cross section having a second cross-sectional dimension in the width direction, and a tapered portion extending in the width direction at least partially between the first end and the second end, wherein the first end of the body is configured to be initially retained in a cannula and the second end of the body is configured to be inserted into an eye;
wherein the first cross-sectional dimension is larger than the second cross-sectional dimension;
wherein a length of the first end of the body to the tapered portion is less than 50% of the total length of the implant;
wherein the height is substantially constant from the first end to the second end;
wherein a retention force of the implant within the cannula is from about 0.030 N to about 0.260 N; and
wherein a ratio of a diagonal dimension of the first cross-section, as a measured retention dimension, to an inside diameter of the cannula is between 1.0064 and 1.09 such that the body is configured to be inserted and removed from the cannula by a user for insertion of the body into an eye of a patient for medical treatment of the eye.
