What Good Is "Smart Polymers?"

Hydroxyapatite coral - In surgery, as implants for the formation of the supporting stump used a variety of materials, constructions and shapes. Conventionally all of them can be divided into four groups: patient's own tissue, allogeneic or taken from another person, materials taken from animals, and materials of non-biological origin (silicones, hydroxylapatite, polymers, metals, etc.).

As the implant-prosthesis to form a support stump American clinics today use a porous hydroxyapatite material of natural or artificial corals. In Russia currently ophthalmic clinics operate with different, but not necessarily certified implant-prosthesis.

A certification procedure itself in Russia can only pass large implants, mostly Western, producers, because it requires serious material costs. Accordingly, the price of the endoprosthesis after passing all levels has grown significantly.

All groups of implantable materials have their pros and cons. Ideal material for reconstructive plastic surgery to date neither Russia nor the West.

What good is "smart polymers?" Basically, all modern materials are made of ocular implants, hydrophobic, i.e. water repellent. For example, Teflon or silicone; the latter is used in medicine for over 40 years.

These materials are normally two-component, i.e. they have a capsule that contains a silicone gel. In experimental studies, it was found that in simple terms the low molecular weight gel can "trickle" through the shell membrane. These problems sometimes occur, for example following breast surgery.
