Abstract Details



Purpose:

The aim of this study is to evaluate an innovative approach to the surface-bulk characterization and treatments of hydrophobic and premium IOL produced by molding and lathe-cut. Results showed that limitations of traditional methods of treatments and characterization can be overcome.

Setting:

Laboratory R&D SIFI MEDTECH, Aci S.Antonio, Catania, Italy

Methods:

Topographic Profile, analysis of defects and roughness have been conducted by using an innovative applications of an optical profilometer to IOL and mold surface. A treatment for a residual monomer reduction and a new method of control have been applied. An optical analyzer have been used for advanced optical performance analysis.

Results:

The optical profilometer permitted to obtain profile of intraocular lens until to 4-5mm of diameter, in presence of sphere profile or advanced optical profile. The roughness values obtained from the analysis are variable from 10nm to 3,5┬Ám. Analysis of residual monomer showed like as the quantity of it is limited between 0,1 to 1,0%. Finally optical analyzer permitted to obtain wafefront profile and MTF value of advanced optical profile lenses.

Conclusions:

All this developed and validated new method of treatments and characterization are important to develop new IOL with new materials and optimize the process of production. FINANCIAL INTEREST: NONE
