Iontophoresis in Transepithelial Corneal CXL
Narrative Responses:
Purpose
Iontophoresisuses electrical current to enhance penetration of riboflavin into the cornea during corneal collagen cross-linking. It is a new therapeutic approach to progressive keratoconus. The purpose of our study is to assess the effectiveness of this new methodafter 6 months.
Methods
Transepithelial corneal collagen cross-linking by iontophoresis was executed in a series of 6 eyes from 6 patients, with progressive keratoconus. Refractive, topographic, tomographic, anatomical and aberrometric outcomes were analyzed at 1 day, 1 month, 3 months and 6 months after the treatment
Results
Statistically significant data was observed in all parameters studied. Keratoconus stability was noted in all patients.
Conclusion
Iontophoresis in transepithelial collagen cross-linkingis performed with an intact epithelium and offers the advantages of transepithelial technique. The treatment time is reduced from 1 hour to 14 minutes, without reducing the safety and efficacy of the treatment (no haze, no pain, no decrease of visual acuity after surgery, no infection).
