[Current evaluation of myopia correction with the excimer laser]
1Universitäts-Augenklinik Dresden.
Summary
Excimer laser keratectomies offer smooth edges with minimal side effects. Success rates exceed 90% for corrections up to 6.0 D, but higher corrections risk complications and regression.
Area of Science:
- Ophthalmology
- Laser Surgery
- Corneal Refractive Surgery
Context:
- Excimer laser keratectomies are established surgical techniques.
- Current clinical methods include wide-field and scanning-slit approaches.
- Flying-spot techniques are under investigation.
Purpose:
- To evaluate the efficacy and safety of excimer laser keratectomies.
- To analyze the impact of correction amount on outcomes.
- To discuss potential complications and contraindications.
Summary:
- Excimer laser keratectomies yield exceptionally smooth ablation edges with negligible thermal and actinic effects.
- Success rates are high (>90%) for corrections up to 6.0 D, with stabilization within one year.
- Higher corrections (>6.0 D) show decreased success rates (<50%), prolonged regression, and increased complication risks, including corneal scarring.
Impact:
- Provides data on refractive outcomes and complication rates based on correction magnitude.
- Highlights contraindications, such as rheumatic diseases.
- Discusses emerging techniques like astigmatic PRK, LASIK, and hyperopic PRK.
