For example, for such diseases as a cataract, accurate surgical and scientific instruments are simply necessary. The first microsurgical operations of the removal of a cataract consist in the extraction of a muddy crystalline lens from an eye together with its capsule. The operation techniques, developed subsequently, were carried out in such a manner that the capsule of a crystalline lens was kept. Such a way enabled to implant an artificial crystalline lens of an eye naturally. It is important for focusing the image on a retina. In cases when the artificial crystalline lens is not applied, it is necessary to replace its glasses with very big optical force. These glasses have a number of drawbacks. They are heavy and they considerably increase all subjects and distances up to them, deform images, limit a field of vision. Patients get used to these glasses in some months and, in some cases, they refuse, preferring to see worse. Artificial crystalline lenses that have been widespread until were bulky and demanded the greater cut for their implantation. In this connection, the operation always finished by imposing of a seam on an operational cut. Such a cut and a seam defined all complications connected to an operation (a divergence, a suppuration and cuttings of seams, complex "astigmatic" glasses, hemorrhages in a retina and inside of an eye) and terms of rehabilitation of patients (up to 6 months). The introduction of accurate surgical and scientific instruments facilitated the removal of these drawbacks.
