“O&Omdc”is an IOL process engineering company, which also specializes in the manufacture and supply of IOL disposable delivery systems, lens packaging, semi-finished IOLs and Half-Moulded polymers for being used by the IOL industry only.

“O&Omdc”has worked to further Research and Development into the advancement of new IOL polymers using Half-Moulded system for IOLs.
The goal of “O&Omdc”is to provide the highest quality polymer for IOL in line with our customers’ needs and expectations.
“O&Omdc” Hydrophobic intraocular lens materials are manufactured using highly purified monomers“O&Omdc”Polymer is characterized by low residuals which allows to obtain a unique outcome and the best performance.
The hydrophobic material is created to work in combination with “O&Omdc” IOL Mould Technology. The material will be supplied in a Half-Moulded Blank form.
This Half-Moulded Blank product ensures a reduction of IOL manufacturing time and production costs, in addition to increase yield output.
