Purpose of the study was to evaluate the clinical outcomes after implantation of the MyoRing (DIOPTEXGmBH, Linz, Austria) by means of femtosecond laser technology in eyes withkeratoconus. Design: Prospective, non-randomized, interventional clinical study. total of 15 eyes of 12 pa6ents with ages ranging from 13 to 31 years wereincluded. All cases were diagnosed with keratoconus according to the standardcriteria. All cases presented with reduced best spectacle-corrected visual acuity,contact lens intolerance or discomfort, and pachy apex of more than 380 μm.MyoRing inserts, selected according to special nomogram depending on Km, wereimplanted in all cases into an intrastromal corneal pocket created by means offemtosecond technology. Visual, refractive, corneal topography, corneal asphericityand pachymetric changes were evaluated during a 1month follow-up. Uncorrected distance visual acuity (UCVA), best corrected visual acuity (BCVA),manifest refraction, keratometry, corneal asphericity and pachymetry. A significant improvement in UCVA was observed after surgery (P=0.0001), whichwas consistent with the significant reduction in sphere (P=0.0003) and cylinder(P=0.0043).There was also significant improvement in BCVA after surgery (p=0.0256).Furthermore, a significant corneal flattening of a mean value of 6.13 D diopters (D)was found (P=0.0004). Corneal thickening was also observed postoperatively in thepachy apex which was statistically insignificant (P=0.33).There was also increase in Qvalue changing the surface of the cornea into less prolate but it was statisticallyinsignificant (p= 0.497). MyoRing implantation using femtosecond technology in keratoconus allowssuccessful corneal modeling and allows significant improvement in visual, refractiveand keratometric outcomes.
