| 본문 : Purpose: To investigate the changes of higher-order aberration (HOA) after wearing orthokeratology lenses in myopic patients.
Methods: The study included twenty myopic patients visited our clinic from December 2014 to March 2015, whose refractive error was equal to or lower than -6.0 diopters and who were treated with orthokeratology lenses. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and HOA measured by a Zywave (Bausch & Lomb, Inc., Rochester, NY) aberrometer were obtained at baseline and 1 month after the use of orthokeratology lenses.
Results: The age of participants was between 6 and 17 years and the follow-up period was at least 1 month. Orthokeratology lenses were well-fitted in all participants, and there was a significant improvement in UCVA at 1 month (p<0.05), whereas BCVA was not significantly different (p>0.05). Total HOA significantly increased after wearing orthokeratology lenses (p<0.05) with an increase of positive spherical aberration.
Conclusion: After using properly-prescribed orthokeratology lenses for 1 month, the participants had good UCVA and an increase of total HOA with positive spherical aberration.
