Julian Stevens considers the impact of next-generation ocular biomechanics assessments in the clinic

Will we see intraoperative assessments of corneal biomechanics?

Intraoperative assessments will be extremely exacting from a technical point of view compared with what we’re doing now. As soon as you place a drop of topical anesthetic on the cornea, the hydration changes; as soon as you take the epithelium off or make a LASIK flap or create a SMILE lenticule, or even if you fire the femtosecond laser into the cornea, you’re going to change not just the hydration, but a whole ton of other parameters.

Once you start putting femtosecond laser pulses in, you have an amazing array of bubbles (except for Ziemer systems or the megahertz femtosecond lasers of the future) but even then, there is still a lot of light scatter coming back, and that will change the parameters. Intraoperative measurements will be highly complex. But if there’s a need, there will be clever people who will find a solution. It’s probably a “would like” rather than a “must have” right now – there are lower hanging fruits we can grab to get a better outcome.
