Analysis of Influencing Factors of High-Order Aberrations of SMILE with Lenticule Retained

Wavefront analysis and other objective methods are the mainstream approaches for assessing visual quality after refractive surgery, with high-order aberrations being the main observation indicators. Some studies have explored the correlation between various complications after SMILE surgery and high-order aberrations. However, research on lenticule retained after surgery has mainly focused on clinical management and case reports of overt lenticule retained, while there is a lack of high-quality observational studies on the population with covert lenticule retained (periphery residual lenticule) to serve as evidence. This often puts clinicians in a dilemma of whether to perform another surgery to remove the remnants. In summary, although research on lenticule retained after SMILE surgery is gradually increasing, systematic studies on their relationship with higher-order aberrations are still insufficient. This study aims to fill the gap in existing research by comparing and analyzing high-order aberrations between patients with and without periphery residual lenticule, providing a more comprehensive assessment of postoperative visual quality. This will offer important theoretical basis and practical guidance for improving SMILE surgical techniques and optimizing postoperative management.
