About this trial
Crosslinking is a therapeutic technique used to increase the rigidity of the cornea in order to slow or stop progression of keratoconus. The main complication of the treatment of keratoconus by crosslinking is postoperative pain due to the removal of the corneal epithelium. Currently, the management of pain is done through the administration of artificial tears and paracetamol. The amniotic membrane is a biological tissue used in ophthalmology to treat injuries of the surface of the eye. It has healing and analgesic properties.
The objective of this multicenter randomized study is to evaluate the benefit of placing an amniotic membrane on the eye post-crosslinking to reduce pain and promote corneal healing.
Eligibility criteria
Qualifiers
Man or woman between 18 and 65 years old.
Indication for accelerated conventional crosslinking.
Patient with progressive keratoconus (increase in Kmax of ≥ 0.5 diopters in 3 to 6 months or ≥ 1 diopter in 3 to 12 months with loss of 10 microns on minimum pachymetry in 3 to 12 month).
Patient suffering from keratoconus with a compatible topographic form (Kmax ≥ 47.0 diopters (D) and difference inferior-superior of 1.5 D).
Disqualifiers
Woman without effective means of contraception, pregnant or breastfeeding.
Patient who has already benefited from a crosslinking procedure on one of the eyes.
