Morphometric and electronmicroscopic studies of the capsule of a clear lens depending on the degree of myopia and age as compared with the capsule of a clear lens in emmetropia and myopia have shown that with age the anterior capsule of a clear lens becomes thicker, while the posterior capsule becomes thinner and increases in length. This is connected with the weakening of accommodation in the presence of different curvature of the anterior and posterior surfaces of the lens on the background of the lowering of the metabolic level in elderly persons. In myopia, with the development of age changes the thickness of the lens capsule remains almost unchanged. The degree of myopia doesn't influence the thickness and the length of the anterior capsule of the lens, while with the rise of myopia the thickness of the posterior capsules increases. No dystrophic changes in the structure of such a capsule in high myopia were revealed. Hypertrophy of the posterior capsule speaks about the increase of its mechanic strength in a clear lens and is connected with the weakness of accommodation. Such a capsule can serve as a support for IOL implants in patients with myopic refraction.
