Combined Intacs SK and Corneal Collagen Cross-linking for the Treatment of Keratoconus

Purpose: To evaluate the efficacy of the combined treatment of Intacs SK (Severe keratoconus) and corneal collagen crosslinking in the management of advanced keratoconus (KC). Setting: Private laser center, Haifa, Israel. Affiliated to Hadassah Hospital, Jerusalem. Methods: This is a retrospective study. Intacs SK were implanted using manual technique in eyes with moderate-tosevere keratoconus followed by collagen corneal cross-linking (CXL). Evaluation included uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), manifest refraction, slit-lamp examination and corneal topography. Ocular response analyzer (ORA) was used to assess the corneal hysteresis (CH) and the corneal resistance factor (CRF). Results: We report on improvement of the UCVA, BSCVA, decrease in myopia, astigmatism and keratometry readings. No significant change in CRF or CH was noted. Conclusion: The combined treatment of Intacs SK and corneal CXL for the treatment of advanced keratoconus is safe and effective. The combined treatment resulted in improved UCVA, BSCVA, keratometry readings and regularization of the topography but no significant change in CRF and HS.
