Purpose:
To present the first patient treated with an optimized prolate ablation algorithm (OPA) with the NIDEK Advanced Vision Excimer laser platform (NAVEX; NIDEK, Gamagori, Japan).
Methods:
A patient with moderate myopia and large scotopic pupils received contralateral LASIK treatment, treating one eye with OPA and the other with conventional treatment.
Results:
At 3 months postoperatively, corneal topography and wavefront analysis show a prolate result with the OPA treatment and an oblate result with the conventional treatment.
Conclusions:
The creation of prolate cornea over the entire scotopic pupil, the reduction of spherical aberrations, and an ablation architecture that compensate for age-related changes was achieved immediately after LASIK. The OPA treatment may result in better visual quality over the long-term compared to conventional LASIK.
