A new technique of femtosecond laser, CIRI or "Conic Intrastromal Relaxing Incisions "different types can correct astigmatism up to now difficult to correct, according to a study released by Dr. Roberto Zaldivar, scientific director of the Instituto Zaldivar (Mendoza - Argentina) at the annual meeting of the American Society of Cataract and Refractive Surgery ..
In his presentation, Dr. Zaldivar refers to the possible application of the technique to different groups of patients with astigmatism not easy to correct, as patients with dry eye, or after cataract or keratoplasty interventions in Needing a procedure to correct residual refractive errors, as a minimally invasive and effective in correcting small amounts of cylinder and sphere.
All refractive procedures available to date show any side effects. Corneal incisions are characterized by low predictability, epithelial growth potential, or hyperopic changes, the PRK surgery may result in "haze" (clouds), regression and discomfort, and the LASIK may occur with irregular edges cut at the interface epithelial growth, and dry eye in older patients. All these changes may affect the quality of the patient's vision. For this reason, and because most of the complications of refractive surgery can take place on the corneal surface, it is now to develop safe and effective intrastromal procedures, as described by Dr. Zaldivar.
The new advanced technique creates intracorneal incisions without damaging the epithelium, and shows great stability in oblique incisions, less and less dry eye denervation and additionally can add new incisions, does not affect the optical zone and may be combined with other intraocular procedures, including the implantation of phakic lenses (ICL) and pseudophakic (IOLs).
While clinical studies to date show the stability and predictability of their results at 6 months, is now developing new applications nomograms and more cases, in order to determine its effectiveness and predictability long term.
