• Extension C-eye on the Amaris laser systems in treatment position


C-eye Corneal Crosslinking 

The integrated solution with SCHWIND AMARIS Excimer Lasers.

C-eye puts modern CXL technology together with SCHWIND AMARIS excimer lasers.

Optimised CXL workflow with SCHWIND AMARIS

Elevated safety and effectiveness through preset application protocols and special irradiation profile 

Wide range of applications and high variability

Treatment of ultrathin corneas (sub400) 

Simple operation and mobility

This lets you perform CXL quickly and easily following a refractive or therapeutic laser treatment, without requiring the patient to change position. The device and the patient’s eye are aligned precisely and easily using the joystick of the AMARIS’ 
patient bed.

If there is a laser treatment following CXL, the SCHWIND AMARIS adjusts for the change in ablation behaviour1 with a specially adapted profile.

Additional safety

C-eye sets a new standard in safety and effectiveness for the patient, with preset irradiation protocols covering the entire range of modern CXL applications. Depending on the protocol, C-eye uses pulsed or continuous UVA light, perfectly adjusted for the individual treatment. The patient’s stromal pachymetry can be also considered (sub400 protocol).

A thickness-adjusted irradiation profile delivers more energy in the corneal periphery, providing an optimised CXL effect. 


Different light intensities

C-eye offers a broad selection of UV intensities, ranging from 3 to 30 mW/cm². The display clearly shows the energy level and remaining treatment time.

Mobile and flexible

C-eye is highly mobile. It needs no cables in operation, is portable, and can be taken anywhere in its practical carry case. A USB cable is used for charging as well as updating, for example when new protocols are available.


A single riboflavin solution for all treatments

A riboflavin solution was developed specifically for C-eye to enable the execution of the full range of irradiation protocols.2

Customised and individual

C-eye includes different profiles for crosslinking treatment. The effectiveness of the stored irradiation protocols has been demonstrated in numerous studies.

In addition to conventional protocols, C-eye also features additional customised programs:

  • Keratoconus sub400 protocol 
    The sub400 protocol is for patients with thin or ultrathin corneas, and requires the input of stromal thickness for the delivery of the correct amount of energy. This individualised fluence delivers a safe irradiation to stabilise the cornea, while reducing UV exposure to avoid endothelium damage.
  • Refractive protocol
    The refractive protocol is used for brief crosslinking immediately following a treatment like FemtoLASIK, PRK or KLEx. It is designed to improve biomechanical strength in high-risk patients with postoperative thin corneas.
  • Keratitis protocol
    The keratitis protocol is used for PACK-CXL, the UVA treatment of corneal infections. PACK-CXL is typically performed at a slit lamp, without the use of SCHWIND AMARIS.
