Comparison of the Optical Biometry Based on Swept-Source Optical Coherence Tomography and Ultrasound-Based Biometry Device in Patients With Mature Cataract

open access: yesInternational Journal of Clinical Practice
Conclusion: AL and ACD measurements from the optical biometry based on swept-source OCT and ultrasound can be used interchangeably in patients with mature cataract. However, LT measurements from the two devices should not be considered interchangeable.
