Abstract: The changes of axial length, keratometry and refractive status after infantile cataract surgery are important for surgical timing of secondary intraocular lens (IOL) implantation and calculation of IOL power. The growth rate of axial length is related to age of surgery, laterality of congenital cataract (unilateral or bilateral), postoperative complications and so on. Postoperative myopia shift is difficult to predict due to axial elongation, and it is also affected by the age of surgery, the timing of intraocular lens implantation and the value of target refraction.(Int Rev Ophthalmol, 2021, 45: 307-311)

Key words: congenital cataract, intraocular lens, axial length, myopic shift, corneal refractive power
