We are expecting new advancements in AS-OCT imaging in the near future. Future OCT systems will have increased scanning speed and better axial resolution, which may allow us to visualize at the cellular level. AS-OCT systems can be used to analyze corneal power.[86] The image acquisition speed and resolution of AS-OCT systems are higher than the optical corneal tomography systems.[87,88] As a result, AS-OCT may be the most efficient technique for preparing corneal elevation maps, especially in eyes with corneal scarring.[19]

The integration of OCT systems with femtosecond lasers is technically possible and required to create custom corneal incisions in femtosecond laser assisted keratoplasty procedures.[88] New OCT upgrades will also simulate the effect of phototherapeutic keratectomy on the cornea, which will help the surgeon decide the depth of laser ablation in phototherapeutic keratectomy. OCT may be an integrated part of slit lamps and operating microscopes in the near future. Current developments promise us new clinical and diagnostic applications of AS-OCT.
