DYNAMIC LASER BEAM CHARACTERISTIC MEASUREMENT SYSTEM FOR OPHTHALMIC SURGERY AND ASSOCIATED METHODS

摘要

A dynamic laser beam characteristic measurement system for ophthalmic surgery and a method for the same are provided to correct a laser surgery system that is used during surgery process on a real time base. The dynamic laser beam characteristic measurement system for ophthalmic surgery includes a sampler(16), a unit for measuring fluence distribution of a beam reference portion, and a unit for calculating laser beam characteristics from the measured fluence distribution. The sampler(16) is disposed to sample the beam of laser shot from a pulse type processed laser as a reference portion. The unit for measuring the fluence distribution is disposed on a processing plane. The measuring unit includes a laser beam fluence profiler(20).
