Method and system for optimising wavefront-guided refractive laser surgery

摘要

A method for optimizing a prescription for laser-ablation corneal treatment achieves the modification of wavefront-based refractive correction data with the use of user/doctor-input nomograms. Data comprising a wavefront description of a patient eye are received (101) and displayed (103) to a user, who can then make modifications (105) to these treatment data. A modification is calculated (106) based upon the desired correction to yield corrected wavefront description data, which are displayed (108, 109, 110) to the user. A system (10) includes a processor (12) and a device (11) for transmitting a wavefront description of a patient eye to the processor. An input device (48) is adapted to receive a desired correction to the wavefront description data. Software (13) is resident on the processor having code segments for implementing the calculations (106) as described.
