Summary
Radial keratotomy effectively improved vision for many myopia patients, with 99% achieving 6/12 vision. This surgical procedure prioritized minimizing complications, resulting in excellent outcomes and minimal side effects.
Area of Science:
- Ophthalmology
- Surgical Procedures
- Refractive Surgery
Background:
- Radial keratotomy is a surgical procedure to correct myopia and myopic astigmatism.
- Previous studies have shown varying results regarding efficacy and complications.
Purpose of the Study:
- To report outcomes of 500 consecutive radial keratotomy procedures.
- To evaluate the safety and efficacy of a protocol designed to minimize complications.
Main Methods:
- Prospective study of 500 eyes undergoing radial keratotomy.
- Out-patient surgery under local anesthesia with a 99.2% follow-up rate.
- Surgical protocol focused on complication minimization, including single-pass incisions and visual axis centering.
Main Results:
- 99% of low myopia, 91% of moderate myopia, and 41% of high myopia patients achieved 6/12 unaided vision.
- Persistent hypermetropia (+1.00D or greater) occurred in 0.4% of cases.
- Secondary astigmatism (1.00D or greater) occurred in 1% of cases; no blinding complications were reported.
Conclusions:
- Radial keratotomy can achieve good unaided vision with a low complication rate.
- The surgical protocol effectively minimized side effects like hypermetropia and astigmatism.
- Focusing on safety and minimizing complications is crucial for successful radial keratotomy outcomes.
