Abstract

Purpose : To evaluate the predictability of ISRS depth using anterior segment optical coherence tomography (AS-OCT)

Methods : Transversal study of 33 eyes, which underwent intrastromal femtosecond, assisted ICRS with the Visumax. Postoperatively, AS-OCT distances from the anterior corneal surface to the anterior surface of the ring, ring depth and incision depth was evaluated, and compared with the attempted depth

Results : Distance from the ring apex to the anterior corneal surface was shorter (283 um) than the target femtosecond depth (471 um), probably due to stromal compaction (P<0.05)

Conclusions : In order to assess segment depth, incision depth may be considered since AS-OCT provides evidence of stromal compaction after femto-assisted ISRS implant.

This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.
