Summary
Ocular higher-order aberrations (HA) increase significantly after age 50, primarily due to lens changes. Corneal HA did not show age-related changes, suggesting customized ablation needs careful consideration in older patients.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Higher-order aberrations (HA) impact visual quality.
- Understanding age-related changes in ocular and corneal aberrations is crucial for refractive surgery planning.
Purpose of the Study:
- To compare ocular and corneal higher-order aberrations (HA) across different age groups.
- To investigate the relationship between age and specific types of HA.
Main Methods:
- An observational, cross-sectional study involving 66 normal subjects (ages 4-69).
- Wavefront aberrations (ocular and corneal) were measured using a Hartmann-Shack aberrometer.
- Analysis focused on the central 4 mm of the visual field.
Main Results:
- Ocular coma-like, spherical-like, and total HA significantly correlated with age.
- Corneal aberrations did not show a significant correlation with age.
- A significant increase in ocular total HA was observed after age 50.
Conclusions:
- Ocular aberrations increase notably after age 50, attributed to lenticular HA.
- Customized ablation strategies require careful consideration in presbyopic individuals due to age-related ocular aberration changes.
