The purpose of this review is to compile information on the optical and healing properties of the cornea when exposed to infrared lasers. Our long-term goal is to optimize the treatment parameters for corneal injuries after exposure to infrared laser systems. The majority of the information currently available in the literature focuses on corneal healing after therapeutic vision correction surgery with LASIK or PRK. Only a limited amount of information is available on corneal healing after injury with an infrared laser system. In this review we will speculate on infrared photon energy absorption in corneal injury and healing to include the role of the tear layer. The aim of this review is to gain a better understanding of infrared energy absorption in the cornea and how it might impact healing.
