Summary
Visual aberrations like glare and halo after laser vision correction (LASIK) can impair function. A novel LASIK enhancement successfully resolved these symptoms by correcting spherical aberrations.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Visual aberrations, including glare and halo, are known complications following laser in-situ keratomileusis (LASIK).
- These visual disturbances are often more pronounced in individuals with higher refractive errors and larger pupil sizes.
- Functional impairment despite good visual acuity can occur post-LASIK.
Observation:
- A patient presented with significant visual aberrations after LASIK, leading to functional impairment.
- Despite achieving good Snellen visual acuity, the patient experienced debilitating symptoms of glare and halo.
- The patient's symptoms were attributed to uncorrected spherical aberrations.
Findings:
- An InterWave-guided LASIK enhancement procedure was performed.
- The enhancement involved a multipass, multistage treatment approach.
- This treatment successfully corrected the patient's spherical aberrations.
Implications:
- This case highlights the potential for LASIK enhancement to resolve visual aberrations.
- Multipass, multistage LASIK enhancement can be an effective strategy for managing functional visual impairment post-LASIK.
- Correcting higher-order aberrations, such as spherical aberrations, is crucial for optimizing visual quality after refractive surgery.
