Objectives:
The objective of this study is to investigate the
clinical effects of orthokeratology lens wear on inhibition of
the myopic progression and axial length elongation in Korean
children with myopia.
Methods:
The authors reviewed out-patient records of 37
eyes of 19 patients wearing orthokeratology lenses. The 46
eyes of 23 patients wearing spectacles were included into
the control group. We evaluated the relationship between
orthokeratology lens wearing people and control group
according to age, initial myopia, initial astigmatism and axial
length elongation.
Results:
There were no significant differences between two
groups as for age, initial myopia, astigmatism, spherical
equivalent and axial length at baseline (t-test, p>0.05).
Significant reduction of refraction was shown in patients
with wearing lenses after 1 year (t-test, p<0.001). The
mean axial length before and after 1 year was 24.62±1.39
mm and 24.73±1.28 mm respectively after lens wearing,
and 24.59±0.74 mm and 24.80±0.71 mm respectively after
wearing glasses. The axial length elongation was 0.11±0.12
mm, and 0.21±0.07 mm in patients with wearing lenses and
glasses, respectively, which showed statistically significant
difference (t-test, p<0.0001).
Conclusions:
The orthokeratology lens was found to be
effective in suppression of myopic progression through less
axial length elongation, compared with the glasses.
