Transepithelial phototherapeutic keratectomy enhances visual outcomes of collagen cross-linking
HYDERABAD, India — Epithelial removal using transepithelial phototherapeutic keratectomy during corneal collagen cross-linking results in better visual and refractive outcomes compared to mechanical epithelial debridement, according to one surgeon.“It is proved that the epithelium at the keratoconus apex is thinner than in the surrounding area. Transepithelial [phototherapeutic keratectomy] allows the excimer laser, set at 50 µm, to ablate the epithelium but also a few microns of stroma at the apex, smoothening the corneal surface before [cross-linking],” Vardhaman Kankaria, MD, said at the joint meeting of the Asia-Pacific Academy of Ophthalmology (Read more...)
