Abstract
Implantable collamer lens (ICL) is widely used because of its good effect of myopia correction.The change of ICL position after surgery increases the risk of postoperative complications such as vision loss, complications, and glaucoma.This article summarizes the influencing factors and predictive parameters of ICL position change from two aspects of arch height and rotation according to ICL type, measurement parameters, the shape of the surrounding tissue of ICL, and the fixed position of ICL and found that type selection parameters, the parameter change of intraocular spatial tissue, the position of the lens foot loop, physiological adjustment and other factors can affect the arch height and axial position of ICL/toric ICL.Correct assessment of these factors can provide references for standardizing ICL operation, improving ICL stability, and reducing complications.It is also a trend to improve the accuracy and predictability of ICL surgery.
Key words:
Implantable collamer lens; Crystal stability; Affecting factors
