Purpose:

To compare clinical outcomes of complete intrastromal ring (Myoring) implantation in two corneal depths of 250 and 300 micron.

Methods:

The study was prospective interventional randomized controlled trial. Patients with keratoconus were divided randomly into two groups. Implantation of complete corneal intrastromal ring was performed in two different stromal depths of 250 micron and 300 micron using femtosecond laser technology. Visual outcomes, corneal biomechanical characteristics, higher order aberrations and other parameters were compared between 2 groups in the course of one-year postoperative follow up.

Results:

In both groups, uncorrected distance visual acuity (UDVA) improved significantly after operation. Coma decreased significantly by the procedure in both groups whereas spherical aberrations had a statistically nonsignificant increasing trend. None of the patients in both groups had intraoperative or postoperative complications. There were no statistically significant differences between 2 groups in any of the mentioned changes.

Conclusion:

Implantation depth of 250 micron has comparable outcomes to the previously used 300 micron implantation depth. It can help in cases of thin cornea that using femtosecond laser in the depth of 300 micron violates the safe margin from endothelium.
