Anterior length assessment
A-scan and B-scan: These techniques use ultrasound waves and the ultrasound probe can be placed directly on the eye or eyelid after using anesthetic drops. A-scan is part of the preoperative evaluation of cataracts, because the length of the eye must be precisely determined before this surgery so that the power of the intraocular lens required can be accurately determined. B-scan also accurately determines the anatomy and internal shape of the eye, so in cases where there is an obstacle to evaluating the retina, such as when there is severe cataract or vitreous hemorrhage, accurate information about the retina can be obtained. It can also be used to examine internal eye tumors. Equipment such as Vumax is used to perform the above procedures. IOL Master is also one of the advanced devices that can be used to measure the anterior-posterior length of the eye and the curvature of the eye surface in one minute without contact with the eye. Therefore, it does not have the risks associated with contact with eye devices and does not require anesthesia to use it.
