The pivotal study will enroll up to 270 patients requiring corneal wound repair following photorefractive keratectomy, or PRK, surgery.
Previous surgical procedures that can place an eye at increased risk include: photorefractive keratectomy (PRK); extra capsular cataract extraction (ECCE); glaucoma drainage surgeries; corneal transplants; and laser-assisted in situ keratomileusis (LASIK).
The company has three specific inventions that came out of the university's holography research: novel photorefractive polymers, a system for recording holograms, and a means of producing 3D telepresence.
RE can be treated by optical methods like corrective glasses and contact lenses or surgical methods like LASIK (laser-assisted in situ keratomileusis) or PRK (photorefractive keratectomy).
However, the rising number of counterfeit products in some developing countries in some regions and the increasing acceptance of corrective procedures such as LASIK and Photorefractive Keratectomy are some of the limiting factors that are expected to hinder the growth of the global colored contact lenses market.

Gene said his son had researched the procedure - photorefractive keratectomy (PKR) - and said he felt it was safer because there was less cornea used.
In addition, laser-assisted vision correction surgeries such as laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) still use ablative technology, which can thin and in some cases weaken the cornea.
