“…However, disease progression can result in contact lens intolerance 23. After the introduction of the intrastromal corneal ring segment, Intacs (Addition Technology Inc., Des Plaines, IL, USA) in 2000 for KC,4 they has emerged as the mainstay of refractive management of contact lens intolerant keratoconic eyes with clear central corneas 3–11…”

“…Recently, Intacs SK was introduced with two significant design modifications – a smaller inner diameter of 6.0 mm compared to 6.8 mm of the standard Intacs; and an elliptical cross-section compared to a hexagonal cross-section of the standard Intacs 11. Although the smaller diameter of Intacs SK was introduced to better address the higher refractive errors associated with the more severe forms of corneal ectasia, the smaller diameter of 6.0 mm with appropriate thickness also has a potential to achieve superior anatomical and refractive outcomes in the earlier stages of KC.…”

Purpose:To examine the safety and efficacy of Intacs SK for moderate to severe keratoconus (KC) using femtosecond technology.Materials and Methods:This prospective, non-comparative study included 37 contact lens intolerant keratoconic eyes (stage II-III) of 24 patients who underwent femtosecond-assisted Intacs SK implantation. Inclusion criteria were mean K readings <56.00 D, corneal thickness >400 μm at the incision site, mesopic pupil <6.50 mm. Evaluation included manifest refraction, slitlamp examination, corneal topography, uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA). P < 0.05 was statistically significant.Results:Thirty-one (83.8%) eyes were classified as Amsler-Krumeich′s stage II and 6 (16.2%) were stage III. Mean central pachymetry was 490.3 ± 37.4 μm. UDVA at 6 months post-operatively was significantly better than pre-operatively (0.90 log MAR ± 0.52 standard deviation [SD] versus 0.32 ± 0.27 logMAR; respectively, P < 0.0001), as was the spherical equivalent (SEq) (−3.64 ± 2.52 D vs. −1.84 ± 2.2 D; P < 0.0001). The mean CDVA and manifest cylinder improved compared with pre-operatively (P = 0.319 and P = 0.078, respectively). Average keratometry decreased significantly from 48.50 ± 3.08 D to 44.40 ± 3.03 D (P < 0.0001).Conclusion:Implantation of Intacs SK using femtosecond laser in moderate to severe KC is safe and effective.
