In the last few decades laser eye surgery has been implemented in various ophthalmic procedures. The most important issue with laser eye surgery is the estimation of temperature rise in eye tissues due to the absorption of high intensity laser radiation. The 2D model of the human eye, using the Finite Elements Method, is developed in order to study the temperature distribution in human eyes subjected to radiation by two infrared lasers, the 1064 nm Nd:YAG and the 2090 nm Ho:YAG laser. The mathematical model is based on the space-time dependent Pennes' bioheat transfer equation supplemented with natural boundary condition equations for the cornea and the sclera. The results could prove to be useful in predicting the damage to intraocular tissues due to heating by infrared laser radiation.

“…The heat source terms were calculated using the laser parameters and the absorption coefficients of the RPE and choroid, which are 100 and 25 cm − 1 , respectively. 29,30,[40][41][42][43][44][45] Equation (2) was solved by COMSOL finite element software (Comsol Inc., Burlington, Massachusetts) with the finite element mesh and boundary conditions described above. The heat source term varies with laser pulse energy and we simulated the temperature increase at different laser pulse energy levels ranging from 0.3 to 1.6 μJ.…”

Abstract.We have developed a two-dimensional computer model to predict the temperature increase of the retina during femtosecond corneal laser flap cutting. Simulating a typical clinical setting for 150-kHz iFS advanced femtosecond laser (0.8-to 1-μJ laser pulse energy and 15-s procedure time at a laser wavelength of 1053 nm), the temperature increase is 0.2• C. Calculated temperature profiles show good agreement with data obtained from ex vivo experiments using human cadaver retina. Simulation results obtained for different commercial femtosecond lasers indicate that during the laser in situ keratomileusis procedure the temperature increase of the retina is insufficient to induce damage.
