When gamma ray crosslinked, PEO gels implanted in the cornea do not cause tissue necrosis resulting in implant expulsion. PEO is not colonized or infiltrated by cells and is mechanically and optically stable. One of the most important advantage using gels is that at any postoperative times, the track's volume can easily be augmented or decreased to finely adjust the refractive correction and, if need be, totally removed from the track. With PEO, GIAK is a safe procedure. A corneal implant designed to correct myopia should have and give a long trouble-free life, as surgery might occur as early as age 20. Therefore even if performed in a short lived animal (cat) a 28 months study cannot be considered a `long' term follow-up. As the cat cornea differs both mechanically and morphologically from man, a human DFA phase I pilot study is necessary.
