Purpose:
|
To evaluate clinical outcomes of Intrastromal corneal inlay implantation using femtosecond laser technology in keratoconic eyes.
|
Methods:
|
A total of 20 eyes of 20 patients entered the study. Annular Intracorneal inlays with an 80 micron thickness and 6 mm diameter were implanted into an intrastromal corneal pocket created using femtosecond laser. Visual, refractive, corneal topography, aberrometry, and pachymetric values were evaluated during one-year follow-up period.
|
Results:
|
Uncorrected distance visual acuity improved significantly one month after operation while corrected distance visual acuity improved nonsignificantly. Both spherical and cylindrical components of refraction reduced significantly after one month. There was a significant reduction in keratometry (mean 5.6 D)in the first month too. No significant changes were detected in these parameters between first and 12th months. A statistically significant increase in primary spherical aberration was found 1 month after surgery. Total higher order aberrations and coma reduced non significantly through the follow up period. In one patient with severe keratoconus we exchanged the Inlay with MyoRing because of residual myopia and patient dissatisfaction.
|
Conclusion:
|
Annular intracorneal stromal inlay implantation using femtosecond technology in keratoconus has acceptable safety and efficacy profile.
