Abstract: With the advent of the era of precise refractive cataract surgery, intraocular lens (IOL) has been widely used in clinical treatment. The stability of IOL mainly includes the stability of longitudinal position and horizontal position, including the effective position, decentration, tilt, and the rotation stability of IOL. The change of intraocular position of IOL will affect the refractive state and wavefront aberrations, especially the high-order aberrations and imaging quality. We will review the influencing factors of IOL stability, including the characteristics and shapes of capsulorrhexis, the designs and materials of IOL, the eye tissue and the surgery factors, which should be paid more attention.(Int Rev Ophthalmol, 2021, 45：404-408)

Key words: intraocular lens, effective intraocular lens position, decentration and tilt, rotation stability
