Going Beyond Gullstand

Are LASIK ablations good enough, or could they be improved by using more accurate individual-patient parameters? Arthur Cummings, MD, FRCS, believes outcomes can be made more accurate, and he notes that current ablations are based on the Gullstrand Eye model that assumes 43 D cornea and an axial length of 24 mm. “Irrespective of how sophisticated the data is that you’re going to use to drive the treatment, when you enter it into the laser, the laser thinks you are treating Gullstrand’s Eye,” Dr Cummings said.
