Finite-Element model of corneal implanted with Intracorneal Ring Segments, published in IOVS
The corneal response to the implantation of Intracorneal Ring changes in normal and keratoconic is studied through Finite-element modeling. Refractive changes are predicted as a function of ICRS geometry (triangular, such as in Ferrara rings, or hexagonal, such as in Intacts), ICRS dimensions and optical zone. These results give insights into the mechanism of the ICRS and will lead toward more predictive results of ICRS surgery.
The study has been published today in IOVS: Kling and Marcos, “Finite-Element Modeling of Intrastromal Ring Segment Implantation into a Hyperelastic Cornea”, Investigative Ophthalmology and Visual Sience 2013, 54 881-889
