The AMARIS laser systems use a novel, sophisticated approach to minimize the thermal load on the cornea. The Intelligent Thermal Effect Control (ITEC) software dynamically limits the local spot frequency without affecting the laser pulse frequency. The use of defined pulse sorting provides extremely smooth surfaces and mild ablations. The thermal load of a pulse depends on the energy, the reflectivity, the thermal conductivity, the density, and the heat capacity. As the energy increases, the thermal load of a pulse increases. The heat propagation is characterized by a flow of heat from warmer to colder areas. This results in lower peak temperatures spread over wider areas. The cumulative thermal load of a refractive treatment increases during irradiation and depends on the effective local repetition rate of the system. Excessive thermal load on the cornea can be avoided by using sophisticated algorithms that cover all aspects of dynamic heat propagation. ITEC minimizes the thermal load on the cornea by blocking small areas around the laser spots for longer intervals and wider areas for shorter intervals. This ensures a thermally optimized, dynamically adapted distribution of laser pulses during treatment. With ITEC, corneal damage due to long exposure times is avoided. This method results in minimized thermal load on the cornea, optimized refractive outcomes and better visual quality after surgery. Excessive thermal load on the cornea can be avoided by using sophisticated algorithms that cover all aspects of dynamic heat propagation.
