In summary, ICL implantation to treat high myopia using Visian ICL V4c or Visian ICL V4 achieved similar efficacy, but Visian ICL V4c caused more HOA, especially spherical aberration, but there was no difference in CF and subjective visual quality.

The new type implantable Collamer lens with a central hole (V4c-ICL) is widely used to treat myopia. However, halos occur in some patients after surgery. The aim is to evaluate the effect of V4c-ICL implantation on vision-related daily activities. This …

To investigate two-year outcomes of Visian Implantable Collamer Lens with a central hole (ICL V4c) implantation for correcting high myopia. Sixty-one eyes of 32 patients went through ICL V4c implantation. Safety, efficacy, predictability, and intraocular pressure were evaluated 2 …

During the procedure, an eye surgeon such as Dr. Kraff implants a biocompatible Visian ICL lens behind the iris and in front of the eye's natural lens to correct vision problems. This offers a permanent yet reversible solution for refractive errors such as myopia, and astigmatism.

Jul 5, 2022 · Studies have shown that ICL V4c implantation produces better visual quality compared to that of laser-assisted in situ keratomileusis and small incision lenticule extraction.

Jan 31, 2025 · EVO ICL is a state-of-the-art vision correction procedure that involves implanting a biocompatible Collamer lens between the iris and the natural lens of the eye. Unlike LASIK or SMILE, which reshape the cornea, EVO ICL works with …

Mar 22, 2024 · Posterior chamber phakic intraocular lens (ICL), also known as implantable contact lens, provides a new pathway for treating refractive errors beyond corneal refractive surgery [8, 9]. It...

Dec 30, 2024 · Therefore, in the 5-year follow-up study, we observed that ICL-V4c implantation is a safe and effective treatment for high and super-high myopia. This study retrospectively reviewed 64 patients (a total of 125 eyes) who had undergone ICL-V4c implantation for 5 years.

Low-order aberrations (defocus and astigmatism), coma, and subjective visual quality had no significant difference between ICL V4 implantation and ICL V4c implantation (P >.05).The 2 kinds of ICL Visian ICL V4 and Visian ICL V4c had similar efficacy of visual quality for high myopia.

What is ICL Eye Surgery? ICL eye surgery involves the implantation of a Collamer lens inside the eye, positioned between the iris and the natural lens. Unlike LASIK, which reshapes the cornea, ICL surgery works by adding a lens to improve vision.
