Implantable Collamer Lens (ICL) implantation is an effective surgical method for correcting high and extreme myopia, especially in patients with thin corneas or those who are not suitable for laser procedures.[3] The ICL lens is implanted in front of the original lens, which remains in place, and can correct up to minus 20 diopters.[3] Although ICL implantation achieves favorable visual outcomes, some patients experience postoperative visual disturbances such as halos, stars, and annular disturbances, which are often accompanied by an increase in higher-order aberrations.[1][2] Higher order aberrations have a higher value in the early postoperative period and gradually decrease.[2] Factors affecting the occurrence of aberrations after implantation include the size and location of the lens, as well as the individual characteristics of the patient's eye. Understanding the patterns of aberration changes and their impact on the quality of vision is important for improving postoperative outcomes and informing patients about expected vision impairments.
