C3r is a keratoconus treatment. Keratoconus is a fairly rare condition of the eye where the cornea becomes stretched and begins to form something of a bulge or cone shape where it should usually be round.

Corneal cross-linking (CXL)is a treatment with the aim of strengthening the corneal stromal tissue through the formation of new chemical bonds between stromal fibres.


Clinical Experience

In recent years corneal cross-linking has become the standard procedure for treating patients with progressive keratoconus and other ectatic corneal diseases because of its effectiveness and lack of serious side effects. A large number of major clinical studies has proven the effectiveness of CXL and the lack of serious side effects. More than 85% of eyes treated with CXL showed a significant increase in BCVA. Six months after the procedure cylinder was reduced in the majority of patients.


Corneal cross-linking is a process of photo polymerization. During this process singlet oxygen is being created with the use of riboflavin as a photo mediator activated by UV light. Free radicals lead to physical intra- and inter-helical cross links of stromal collagen fibres. This process takes place mainly in the anterior 200 μ to 250 μ of the stroma.

The Device

The PXL PLATINUM 330 was designed with a special focus on effectiveness, safety and user friendliness and incorporates the latest clinical experiences. It enables the user to select the required energy levels: 3 mW, 9 mW, 18 mW and 30 mW per cm2 with automatic time adjustment. Furthermore it allows pulsed radiation in connection with the latest experience in treating infectious keratitis, with adjustable illumination on /off intervals. Also dedicated LASIK / PRK modes are available.
