ABSTRACT
The adult crystalline lens measures approximately 9.6±0.4 mm in diameter with an approximate anterior-posterior diameter of 4.2±0.5 mm.1,3,11 Figure 1.1 shows the empty capsular bag after removal of the crystalline lens. The diameter of ciliary sulcus 11.1±0.5-mm, according to studies performed at the Center for Research on Ocular Therapeutics and Biodevices, Storm Eye Institute, Charleston, SC, USA (now renamed as David Apple, MD, Laboratory for Ophthalmic Devices Research, John A Moran Eye Center, Salt Lake City, Utah, USA).3 The anterior and posterior poles form the optical and geometrical axis of the lens. Although the normal lens is transparent and clear in vivo, it is seldom completely colorless; even in childhood a slight yellowish tint is present that tends to intensify with age.
