Medical implant

A medical implant comprising:

• a substantially wedge-shaped body having a height, a width, a first layer, a second layer, and a third layer, wherein the body further includes a first end having a first cross-section having a first cross-sectional dimension in the width direction and a second end having a second cross-section having a second cross-sectional dimension in the width direction, wherein the body is configured to be inserted into an eye;
• the body further including a tapered portion extending in the width direction at least partially between the first end and the second end;
• 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 first layer, the second layer, and the third layer are substantially planar and substantially parallel to each other;
• wherein the first layer and the third layer comprise a first material, and the second layer comprises a second material;
• wherein the first cross-sectional dimension is larger than the second cross-sectional dimension;
• 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.

An ocular medical implant comprising:

• a substantially wedge-shaped body having a height, a width, a top surface, a bottom surface, 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 top surface is substantially parallel to the bottom surface;
• 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.
