Figure 1.

Biometric measurements provided by 3D-OCT. 3D-OCT shows the scanned capsule, which is an imaginary line of the crystalline lens seen from the anterior and posterior capsule, provided by the built-in algorithm of the laser system. The equator plane is a straight line connecting both ends of the imaginary lines. Anterior chamber depth (ACD) is determined by calculating the distance along the visual axis between the corneal epithelium and the anterior lens surface by OCT while aqueous depth (AD) is defined as the distance from the corneal endothelium to the lens. Lens meridian parameter (LMP) is the vertical distance from the corneal apex to the equator plane of the crystalline lens. The anterior segment length (ASL) was calculated by adding LT to ACD. The crystalline lens was analyzed by dividing it into anterior part (aLT) and posterior part (pLT), bordered by the equator plane.
