Purpose
Refractive surgery remains one of the most common procedures among young patients, making safety and predictability essential. To optimize outcomes for borderline cases, we evaluated corneal biomechanics using the Corvis ST device. We compiled a database of 30 patients who were ideal candidates based on topographic results; however, their Corvis ST measurements raised some concerns. Consequently, we performed simultaneous corneal cross-linking to reinforce corneal stability and compared the Corvis ST parameters before and after the cross-linking procedure.
Setting
We analyze 25 patients whit adequate corneal topography, whit suspicious Corvis results, they all have femtolasik assisted lasik , Sirius personalized whit saving tissue preference and 80 microns flap, and crosslinking Xtra.
Methods
Comparative retrospective study
Results
The utility of corvis in describing what patients may undergone to surgery when we have acceptable corneas it's still to be determined, but the effectiveness of croslinking Xtra was evident in 25 of the patients increasing the standards of the corvis results, and in the follow-up we haven't seen any post lasik ectasia.
Conclusions
We need a larger group of patients for fully compare the advantages of corvis test results, but this results seems promising in that application of crosslinking Xtra to this kind of patients.
