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