Contribution of Fourier-domain optical coherence tomography to the diagnosis of keratoconus progression.

Purpose: To determine the anatomic criteria for diagnosing keratoconus progression by corneal optical coherence tomography (OCT).

Setting: Quinze-Vingts National Ophthalmology Hospital, Paris, France.

Design: Prospective case series.

Conventional and Iontophoresis Corneal Cross-Linking for Keratoconus: Efficacy and Assessment by Optical Coherence Tomography and Confocal Microscopy.

Purpose: To compare the efficacy, safety, and microstructural corneal changes during 2 years after conventional corneal collagen cross-linking (C-CXL) and transepithelial corneal CXL by iontophoresis (I-CXL) for keratoconus.

Methods: Eighty eyes of 80 patients with progressive keratoconus were treated by C-CXL (n = 40) or I-CXL (n = 40). Patients were investigated before surgery and 1, 3, 6, 12, and 24 months after treatment.

Optical coherence tomography and confocal microscopy following three different protocols of corneal collagen-crosslinking in keratoconus.

Purpose: We compared the efficacy and early morphological changes in the cornea following conventional (C-CXL), transepithelial by iontophoresis (I-CXL), and accelerated (A-CXL) collagen cross-linking in keratoconus.

Methods: A total of 45 eyes of 45 patients with progressive keratoconus who underwent corneal collagen crosslinking (CXL) was divided into three groups: C-CXL (n = 15), A-CXL (n = 15), and I-CXL (n = 15). Patients were examined before surgery and at 1-, 3-, and 6-month intervals following surgery.
