Abstract
The rise of excimer laser refractive surgery in the last two decades has been reflected in a growing group of patients with a history of this procedure who now need cataract surgery. Because the generated modifications to the cornea with the laser photoablation, determining the corneal power, necessary for calculating the power of the intraocular lens to be implanted during the cataract surgery, is difficult. We
review the causes of these errors of measurement and existing approaches to minimize its impact. MÉD.UIS. 2017;30(1):99-105.
