Intrastromal presbyopia treatment

In a worldwide first, Dr Luis Ruiz presented the preliminary clinical results of an ongoing pilot study concentrating on the non-invasive intrastromal correction of presbyopia.

The Femtec femtosecond laser (20/10 Perfect Vision) applied a customized pattern to the cornea causing a local reorganization of biomechanical forces. In presbyopia, the applied pattern led to a well-defined central steepening of the cornea, resulting in a central increase of refractive power.

“Because the refractive power change is only centrally induced, a significant increase of near vision is evoked, whereas distance vision is only minimally affected,” Dr Ruiz said.

“This non-invasive technique has a huge potential to improve the near vision instantaneously by several lines, and so far there has been no long term downsides observed,” Dr Ruiz said.

He said preliminary results indicate that it may be possible to use this technique on all kinds of intrastromal corrections.
