The Haag Streit CGIL iridectomy contact lens was designed by Riquin, Fankhauser et al. to perform full thickness peripheral laser iridectomies. The use of this lens enhances the safety and efficacy of the laser procedure. It increases the energy density on the iris while minimizing it on anterior and posterior structures, such as cornea and lens capsule. The magnifying effect allows for improved aiming accuracy and higher success rate. Perfect handling is facilitated by the large diameter. It is made of mineral glass and is antireflection coated.
