Application of swept-source optical coherence tomography biometer in cataract

Recently, optical biometers based on swept-source optical coherence tomography (SS-OCT) technology have been applied to clinical ophthalmology.Compared with previous optical biometers, SS-OCT instruments have many advantages, such as faster processes, more accurate results, higher detection rate, and more built-in formulas for calculating the intraocular lens (IOL) power; moreover, SS-OCT images can be used to detect preliminary maculopathy and predict postoperative tilt of IOL.In this paper, we reviewed the application of SS-OCT biometer in cataract, mainly focus on the principle of work, the evaluation of repeatability and reproducibility, the consistency comparison with other biometers, and the application of SS-OCT in other aspects of cataract.
