5 Key Takeaways

• 1

  Higher-order aberrations (HOAs) disrupt light travel in the eye and cannot be corrected with standard glasses or contact lenses.

• 2

  Most human eyes have some degree of HOAs, but not all patients require HOA-correcting contact lenses.

• 3

  Patients with corneal irregularities or high ametropia often experience bothersome symptoms like glare and blurred vision.

• 4

  Quantifying HOAs effectively relies on wavefront data from an aberrometer and requires precise measurement conditions.

• 5

  HOA correction can significantly enhance vision performance for selected patients, making it a valuable option in eyecare.
