 types of phakic implantable lenses are (1) posterior chamber designs like the ICL, including lenses made by Biotech Vision Care, Care Group, and Eyebright and (2) iris clip anterior chamber designs, including lenses made by Ophtec. While most competing lenses are made from types of silicone or acrylic, we believe our ICLs offer compelling clinical advantages due to our proprietary Collamer lens material, as well as their design and features. We also believe our track record of safety and effectiveness, and high levels of patient satisfaction, are competitive advantages relative to laser surgical procedures and other implantable lenses. Notably, our EVO ICL is the only foldable, minimally invasive posterior chamber phakic intraocular lens approved for sale in the U.S. In addition, competitors from Asia are beginning to

appear in the market with their low-cost version of a posterior chamber implantable contact lens, increasing the level of competition.

The Human Eye

The following discussion provides background information on the structure, function, and some of the disorders of the human eye to enhance the reader’s understanding of our products described in this Annual Report. The human eye is a specialized sensory organ capable of receiving visual images and transmitting them to the visual center in the brain. The eye has an anterior segment and a posterior segment that are separated by the natural crystalline lens.

The anterior segment consists of the cornea, the iris and ciliary body and the trabecular meshwork. It is filled with a water-based fluid called aqueous humor and is divided, by the iris, into an anterior chamber and a posterior chamber. The cornea is a clear lens at the front of the eye through which light first passes and is focused toward the back of the eye. The interior surface of the cornea is lined with a single layer of flat, tile-like endothelial cells, whose function is to maintain the transparency of the cornea. The iris is a pigmented muscular curtain located behind the cornea which opens and closes to regulate the amount of light entering the eye through the pupil, an opening at the center of the iris. The crystalline lens, located behind the iris, completes the focusing of light and can change shape to focus objects at different distances onto the retina, located in the back of the eye. The trabecular meshwork, a drainage channel located between the iris and the surrounding white portion of the eye, maintains a normal pressure in the anterior chamber of the eye by draining excess aqueous humor.

The posterior
