Objective:
To explore the impact of lower- and higher-order aberrations on visual quality and contact lens care.
Key Findings:
- HOAs significantly affect visual quality, leading to complaints like glare and poor night vision despite 20/20 acuity.
- Traditional refraction methods are often insensitive to HOAs, complicating patient care.
- Rigid gas permeable and scleral lenses can effectively reduce corneal HOAs and improve visual outcomes.
- Incorporating HOA-correcting optics into lens designs can enhance patient satisfaction.
Interpretation:
Recognizing the role of HOAs in visual dissatisfaction is crucial for clinicians to improve patient outcomes and satisfaction.
Limitations:
- Wavefront aberrometry is not routinely used in clinical practice.
- Treatment options for HOAs can be complex and are not always straightforward.
Conclusion:
A comprehensive understanding of both LOAs and HOAs is essential for effective patient management and improved visual quality.
