One-year visual outcomes and optical quality of femtosecond laser small incision lenticule extraction and Visian Implantable Collamer Lens (ICL V4c) implantation for high myopia.

Both SMILE and ICL V4c implantation provide good safety, efficacy, predictability, and stability in correcting high myopia. Optical quality including intraocular scattering was great and relatively stable in both groups during the one-year observation period.
