Summary
Radial keratotomy (RK) effectively reduced astigmatism, with initial central corneal flattening and hypercorrection resolving within six months. Corneal topography analysis provided objective evaluation of this refractive surgery.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Topography
Background:
- Radial keratotomy (RK) is a surgical procedure to correct myopia.
- Assessing the impact of RK on corneal shape is crucial for understanding its efficacy and potential complications.
Purpose of the Study:
- To evaluate changes in corneal topography following radial keratotomy.
- To quantitatively assess the refractive outcomes and corneal shape alterations after RK.
Main Methods:
- Corneal topography was performed on 23 patients (40 eyes) before and after radial keratotomy.
- EYE-SYS equipment was utilized for precise corneal shape evaluation.
Main Results:
- Postoperative examination revealed significant central corneal flattening.
- Initial hypercorrection was observed, which gradually decreased over six months.
- Sustained positive outcomes were noted up to 18 months post-surgery.
- Additional corneal incisions effectively reduced astigmatism.
Conclusions:
- Corneal topography provides an objective and quantitative method for evaluating radial keratotomy.
- The study demonstrates the efficacy of RK in correcting refractive errors and reducing astigmatism.
