Implication

Preclinical study demonstrates corneal reshaping via excimer laser ablation in rabbits, suggesting shallow ablations optimize post-surgical corneal surface healing.

Key Points

To establish mathematical and optical parameters for photorefractive keratectomy using excimer laser ablation and evaluate postoperative corneal surface healing.
Derived ablation equations required to achieve specific refractive corrections in the central optical zone.
Implemented beam integration by rotation to improve far ultraviolet beam uniformity.
Evaluated post-ablation corneal healing and surface quality in rabbit models across shallow and deep ablation depths.
Beam integration by rotation successfully enhanced laser beam uniformity for controlled tissue ablation.
At five days post-treatment, shallow corneal cuts produced regular surface healing, whereas deep cuts resulted in highly irregular corneal surfaces as predicted by beam characteristic calculations.
