Abstract: With the prevalence of myopia, there is a trend towards an increase in the number of people requiring vitrectomy to preserve the lens. The risk of cataract after vitrectomy (aqueous eye status) is about 22.5%~60%, and refractive drift after cataract of aqueous eye status surgery has received more attention. Although cataract surgery technology continues to advance and examination equipment is constantly updated, some preoperative, intraoperative, and postoperative factors cause postoperative refractive error to be more obvious than that of normal eye cataract. In addition to paying attention to the patient's ocular surface health, the accuracy and repeatability of optical biometry, and the selection of the appropriate IOL refractive power calculation formula, the change of the axial length and the actual position of the IOL should also be paid attention to. Choosing the appropriate IOL calculation formula can reduce the refractive error after surgery. The SRK/T formula, Kane formula, Haigis formula, and Barrett Universal II formula are used to calculate the refractive error of high myopia, but whether they can be used in patients with cataract of aqueous eye status is worth exploring.  (Int Rev Ophthalmol, 2024, 48:  420-425)
