Purpose:
|
Our aim in this study was to assess effect of Intrastromal corneal ring segment (keraring) implantation on corneal biomechanics parameters measured by ORA.
|
|
Methods:
|
in this study, 21 keratoconic eyes with inclusion criteria were selected and biomechanical characteristics were analyzed before and 1 and 6 months after ICRS implantation with ORA.
|
|
Results:
|
mean CRF and CH and difference CH-CRF measures were not significant in this study at 1 and 6 months after surgery. Mean difference k1, k2 at 1 and 6 months after surgery than preoperation were significant. (p=0.02). IOPg and IOPcc were not significant after surgery. Waveform score increased after surgery. Change of difference CH-CRF with waveform score change measures were significant inversely (p=0.02, R=0.31) .CCT measures were not significant in post operation than pre operation.
|
|
Conclusion:
|
Although global measure of biomechanics in ORA were not changed after ICRS; but waveform score increase showed ICRS can changed unknown factors. corneal shape change after ICRS implantation can explained it too.
