To investigate the safety of CINTACS in patients with keratoconus.
Fourteen keratoconus eyes and their fellow eyes underwent achromatic perimetry (WWP), blue-on-yellow perimetry (SWAP), and OCT before and after unilateral CINTACS. Follow-up was 3 months.
In both the operated and control eyes, none of the indices in WWP and SWAP worsened after CINTACS, and none of the eyes developed visual damage. Although no average significant change in the nerve fiber layer was detected by OCT, high and low suction times correlated with nasal and superior sector thinning one week and one month postoperatively (r=0.7; p=0.02)
CINTACS appear to be safe in keratoconic eyes but care should be taken with prolonged suction times.
