Topography-guided LASIK using Contoura Vision and the Phorcides Analytical Engine significantly improved vision and reduced visual complaints in myopia patients. This advanced excimer laser treatment offers excellent uncorrected and corrected visual acuity outcomes.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery.
- Advancements in technology aim to improve visual outcomes and patient satisfaction.
- Topography-guided LASIK offers personalized treatment based on corneal topography.
Purpose of the Study:
- To prospectively evaluate the clinical outcomes of topography-guided LASIK using Contoura Vision.
- To assess the efficacy of the Wavelight excimer laser and Phorcides Analytical Engine in planning treatments.
- To determine the impact on uncorrected and corrected visual acuity and subjective visual complaints.
Main Methods:
- Prospective, single-arm interventional study involving 130 eyes of 65 patients.
- Patients with myopia or myopic astigmatism were treated with Contoura Vision LASIK.
- Visual and refractive outcomes were measured at 3 months postoperatively.
Main Results:
- 100% of eyes achieved 20/20 uncorrected distance visual acuity (UDVA).
- 92% of eyes had postoperative UDVA equal to or better than preoperative corrected distance visual acuity (CDVA).
- Significant reduction in subjective visual complaints like glare, halos, and light sensitivity was observed.
Conclusions:
- Topography-guided LASIK with Contoura Vision and the Phorcides Analytical Engine optimizes visual outcomes.
- This approach is effective for correcting myopia and myopic astigmatism.
- The technology enhances patient satisfaction by improving visual quality and reducing aberrations.
