Abstract

The lens capsule is the outer lining of the crystalline lens, and its elastic properties directly influence accommodation. Elasticity of the lens capsule and accommodative amplitude decrease over time, due to physiologic, age-related changes. The anterior capsule thickens by approximately 1.2 % per year due to regeneration of lens epithelial cells [1]. Some believe that, as the anterior capsule thickens, it may impede the ability of the lens to become more spherical during accommodation. In addition to a reduction in elasticity, the tensile strength of the anterior capsule also decreases with time [1]. While the elastic and strength changes in the anterior capsule are independent of cataract formation, these characteristics are relevant to small incision cataract surgery, as the strength, thickness, and elasticity of the capsule opening influence the safety of the procedure as well as the refractive outcome.
