Purpose
To present the outcomes of topography-guided opposing dual-segment KeraNatural implantation in keratoconus patients with symmetrical corneal cones.
Setting
Case series
Methods
This study evaluated six eyes from five patients who had undergone dual allogenic intrastromal ring segment (CAIRS) opposite horizontal implantation surgery based on topographic cone location with a follow-up period ranging from six months to three years. Preoperative and postoperative measurements, including visual acuity, refractive, topographic keratometric values and central corneal thickness, were analyzed.
Results
Corrected Distance Visual Acuity increased from 0.88±0.54 preoperatively, to 0.35±0.15 postoperatively and Kmax decreased from 58.31±5.79 D to 52.26±4.25 D. No significant complications reported during the follow-up period.
Conclusion
This case series investigate the outcomes of dual Keranatural implantation in keratoconus patients with symmetrical cones. The findings from this case series may yield enhanced outcomes, necessitating additional exploration and possible implementation as a new standard in keratoconus surgery.
