Summary

A complete intrastromal ring, MyoRing (Dioptex, GmbH, Linz, Austria), suggested by Albert Daxer in 2007, is a relatively new technique that has been demonstrated to treat keratoconus safely and effectively.Corneal collagen crosslinking (CXL), introduced by Wollensak et al. in 2003, has become a standard treatment for progressive keratoconus to slow or possibly stop progression of disease. The formation of the stromal pocket during MyoRing implantation offers the opportunity for simultaneous introduction of riboflavin 0.1% into the pocket followed by UVA irradiation to provide combined treatment in patients with progressive keratoconus.

Conditions

• Keratoconus

Interventions

Type	Name	Description
PROCEDURE	Corneal Collagen Crosslinking	Sterile riboflavin solution 0.1% was then continuously injected for 3 minutes into the corneal pocket via a standard 0.3-mm cannula through the incision tunnel. Standard surface UVA irradiation (370 nm, 3 mW/cm2) was then applied at a 5-cm distance for 30 minutes. After UVA irradiation, a flexible MyoRing intracorneal implant was inserted into the corneal pocket,
DEVICE	Ufalink	UVA irradiation with wave length 370 nm, 3 mW/cm2 is provided with UFalink, device,Russian Federation
