Outcome of Simultaneous Use of Intracorneal Ring Segments With Corneal CXL
To study visual outcomes of simultaneous Intra corneal ring segments with C3R in corneal ectasia.
A retrospective observational study was done. Subjects with documented progression of keratoconus were included in study. Thirty keratoconic eyes who had undergone Femtosecond assisted Intracorneal Ring Segments with simultaneous corneal collagen crosslinking formed study population. Post operative spherical equivalent, Kmax on corneal topography and BCVA on snellen's acuity chart were noted at 1 week, 1 month and 6 months.
Post op Mean spherical equivalent improved from 4.75 ± 0.09 to 1.5 ± 0.7 at 6 months and BCVA in decimal scale improved from pre op value of 0.4 ± 0.12 to post op value of 0.29 ± 0.15 at 6 months.
Simultaneous intra corneal ring segments with C3R showed statistically significant improvement in Mean spherical equivalent and also BCVA improved by three lines in decimal scale at 6 months follow-up.
