Summary
Contact lens fitting after high myopia refractive surgery presents challenges. Rigid gas permeable lenses are recommended for corneal irregularities, while toric soft lenses can correct regular astigmatism effectively.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Refractive Error Correction
Background:
- High myopia correction via refractive surgery can lead to residual refractive errors.
- Post-surgical corneal architecture alterations complicate contact lens fitting.
Observation:
- Two patients with high myopia underwent various refractive surgeries (LASIK, clear lens extraction, RK, PRK).
- Residual refractive errors were managed with rigid gas permeable (RGP) and toric soft contact lenses.
Findings:
- Successful visual acuity (20/25-20/20) was achieved with contact lenses.
- RGP lenses were used for corneal irregularities post-LASIK, with slight decentration noted.
- Toric soft lenses successfully corrected residual astigmatism in a patient with regular corneal surfaces.
Implications:
- Contact lens fitting after high myopia refractive surgery is feasible but challenging.
- RGP lenses are suitable for irregular corneas, while toric soft lenses address regular astigmatism.
- Careful lens selection is crucial for optimal outcomes in post-refractive surgery patients.
