Abstract: The present invention refers to a porous PEEK-type polymer article comprising a porous PEEK-type polymer structure and presenting at least a trimodal pore distribution. The invention describes a process for the production of said porous PEEK-type polymer article comprising: a) contacting a PEEK-type polymer with a composition comprising at least a organic solvent, b) heating at a temperature at which the PEEK-type polymer is dissolved, c) adding at least a porogen agent, d) cooling the mixture obtained in c) at a temperature at least equal or lower than the temperature at which the PEEK-type polymer precipitates, e) forming said cooled mixture into a shaped article, f) removing the organic solvent and the porogen agent, and g) recovering the PEEK-type polymer article.

Abstract: The present invention refers to an implantable optical system comprising a central optical part and an annular anchoring part, where said annular part comprises animals cells, including human cells, that encourage the integration of the implant into the ocular tissue of the patient, as well as a system for dosing chemical compounds directed at a particular function, creating a stabilising microenvironment for the presence of the implant in the tissue. A method for obtaining said system by polymerisation and its applications in various types of ocular disorders is also described.
