RecruitingDevice studyAgreement of Two OCT Biometers: A Pilot StudyThe purpose of this study is to compare the measurements obtained with two different biometers, UNITY Dx and Anterion. In eye care, a biometer is a device that uses laser technology to take highly precise measurements of the eye's internal structures. It is most frequently used to help determine the exact power of the intraocular lens (IOL) needed before cataract removal.
