Morphological Changes in the Cornea Following Cessation of Long-Term Orthokeratology and Outcomes of SMILE Surgery: A Retrospective Comparative Analysis
To investigate ocular biometric and corneal morphological alterations after long-term orthokeratology (OK) lens discontinuation and assess their impact on SMILE outcomes, specifically focusing on visual acuity and corneal parameters, compared to patients without a history of OK wear.
Key Findings:
Long-term OK lens wear resulted in residual corneal flattening and increased astigmatism, which may impact visual outcomes.
Corneal morphology changes persisted even after cessation of OK lens use, indicating potential long-term effects.
SMILE outcomes were comparable between OK users and non-users; however, pre-existing corneal changes may influence surgical results.
Interpretation:
The study highlights the importance of understanding corneal changes post-OK lens wear, as these may affect surgical outcomes in refractive procedures like SMILE.
Limitations:
Small sample size may limit generalizability and statistical power.
Retrospective design may introduce selection bias, affecting the reliability of the findings.
Conclusion:
Further research is needed to fully understand the implications of corneal morphological changes from long-term OK use on refractive surgery outcomes, particularly in larger, prospective studies.
