Abstract:
Compared to other refractive surgeries, the implantable collamer lens(ICL)implantation procedure has become one of the most popular surgical options in refractive surgery. ICL surgery offers advantages such as reversibility, high-definition visual outcomes, and preservation of the corneal anatomical structure. The V4c model, which features a central port, is currently the most widely used in clinical practice and eliminates the need for peripheral iridotomy during the perioperative period. Although excellent uncorrected visual acuity can be achieved postoperatively, some patients may experience visual disturbances in the early postoperative period, such as halo and glare, which may affect visual comfort particularly under low-light conditions. This article reviews visual quality metrics after ICL V4c implantation, including higher-order aberrations(HOA), modulation transfer function(MTF), and contrast sensitivity(CS), along with influencing factors, and discusses potential relative deficits in postoperative visual quality and their underlying mechanisms.
