Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group 1
Measurement of aberrations in patients with keratoconus of grade 1
classic aberrometer and aberrometer AOVIS-1
Measurement of aberrations in early stages (1 and 2) of keratoconus as compared aberrometer AOVIS-1 with a "classic aberrometer".
Group 2
patients with keratoconus of grade 2
classic aberrometer and aberrometer AOVIS-1
Measurement of aberrations in early stages (1 and 2) of keratoconus as compared aberrometer AOVIS-1 with a "classic aberrometer".
Group 3
patients with keratoconus of grade 3
Aberrometer AOVIS-I
Measurement of aberrations in high stages (3 and 4) of keratoconus. Objective characterization of the optical quality of the patient eye by application of wave-front sensing technology in late stage keratoconus The complete procedure in one patient takes less than 5 minutes in only one consultation and is completely non invasive. The optical measurements only involve the use of low power infrared laser
Group 4
patients with keratoconus of grade 4
Aberrometer AOVIS-I
Measurement of aberrations in high stages (3 and 4) of keratoconus. Objective characterization of the optical quality of the patient eye by application of wave-front sensing technology in late stage keratoconus The complete procedure in one patient takes less than 5 minutes in only one consultation and is completely non invasive. The optical measurements only involve the use of low power infrared laser
