Summary
Excimer laser photorefractive keratectomy using the Schwind Keratom laser shows excellent results for myopia correction. This study confirms its safety, efficacy, and predictability in improving vision for patients with myopia.
Area of Science:
- Ophthalmology
- Laser Surgery
Context:
- Myopia affects a significant portion of the population, impacting visual acuity.
- Photorefractive keratectomy (PRK) is a surgical option for myopia correction.
- Excimer lasers are utilized in refractive surgery to reshape the cornea.
Purpose:
- To evaluate the efficacy, safety, predictability, and stability of the Schwind Keratom laser for myopic eye correction.
- To assess visual outcomes following Excimer laser photorefractive keratectomy.
Summary:
- A study involving 253 patients with myopia (-0.75 to -8 D) demonstrated excellent outcomes with the Schwind Keratom laser.
- One year post-operation, 92% achieved uncorrected visual acuity above 20/40, and 90% maintained their best-corrected visual acuity.
- Refractive stability was high, with only 4% experiencing spherical equivalent variation between 6 months and 1 year.
Impact:
- The Schwind Keratom laser offers excellent and comparable results to other refractive lasers for myopia correction.
- The procedure demonstrates high predictability and safety, with significant improvements in uncorrected and corrected visual acuity.
- The study supports the use of this laser technology, particularly for low myopia, and notes its certification in France.
