Simulation of the influence of intrastromal corneal lenticule implantation

SIMULATION OF INFLUENCE OF INTRASTROMAL CORNEAL LENTICULE IMPLANTATION Background: Corneal stromal lenticule is a part of corneal stroma, which arises as a by-product of a refractive procedure ReLex SMILE. Its implantation has successfully been used in treatment of wide spectrum of severe diagnoses such as nonhealing corneal defects or ectasia. There have also been published cases where the lenticule was used in refractive indication such as hyperopia or presbyopia correction. In these indications, a greater emphasis on the refractive outcome is necessary, however, there is still not enough data available on the basis of which we would be able to choose the most suitable lenticule for a specific patient. Purpose: To evaluate changes in corneal refractive parameters after implantation of a stromal lenticule of different thickness. We assume that the refractive outcome depends on optical power of the used lenticule. The other important goal is to analyse possible methods of corneal lenticule preparation and storage and prove the possibility of using one donor cornea for more patients. We want to build a safe approach which would increase the efficiency of the surgery and shorten the waiting time for donor corneal tissue. Methods: We performed an ex vivo non-human study on normotonic porcine eyeballs...
