Purpose.
To evaluate the corneal higher-order aberrations (HOA), contrast sensitivity function (CSF), and light distortion (LD) in patients undergoing orthokeratology (OK).
Methods.
Twenty healthy subjects (mean age: 21.40±8 years) with mean spherical equivalent refractive error M=-2.19±0.97 D were evaluated at 1 day, 1 month, and 1 year after starting OK treatment.
Monocular LD, photopic monocular CSF, and corneal HOA for 6 mm pupil size were measured.
Results.
LD showed an increase after the first night (p<0.05) and recovery to baseline after 1 month, remaining stable after 1 year (p>0.05).
Spherical-like, coma-like, and secondary astigmatism HOA RMS increased significantly (p≤0.022) from baseline to 1-month visit, remaining unchanged over the follow-up.
Contrast sensitivity for medium frequencies (3.0, 4.24, and 6.00 cpd) was significantly correlated with LD parameters at baseline (r≤-0.529, p<0.001).
However, after 1 year of treatment, this correlation was only statistically significant for 12 cpd spatial frequency (r≤-0.565, p<0.001).
Spherical-like RMS for 6 mm pupil size correlated with irregularity of the LD (r=-0.420, p<0.05) at the 1-year visit.
Conclusion.
LD experienced by OK patients recovers after one month of treatment and remains stable in the long term while optical aberrations remain significantly higher than baseline.
