Summary
Customized refractive surgery using adaptive optics improves visual acuity by correcting ocular aberrations. Eliminating high-order aberrations and correcting second- to fourth-order aberrations show promising results for low myopia patients.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Refractive surgery aims to correct vision by reshaping the cornea.
- Customized treatments are increasingly explored to optimize visual outcomes.
- Adaptive optics (AO) allows precise measurement and correction of ocular aberrations.
Purpose of the Study:
- To analyze the impact of various wavefront-guided aberration ablation patterns on visual function.
- To identify effective and feasible patterns for customized refractive surgery.
Main Methods:
- A control study involving six volunteers under dark conditions.
- Ocular aberrations were measured using an adaptive optics system.
- Visual acuity was assessed with different wavefront correction patterns through a 6.0 mm pupil.
Main Results:
- All eight aberration correction strategies demonstrated excellent correction effects.
- All strategies improved visual acuity compared to static correction.
- Correction of high-order aberrations and full aberration correction yielded superior visual acuity compared to low-order correction alone.
Conclusions:
- Eliminating ocular high-order aberrations can enhance visual acuity in patients with low myopia.
- Correcting second- to third-order aberrations and fourth-order spherical aberration represents a potentially effective and feasible approach for customized refractive surgery.
