Pharnorcia is specialized supplier of raw materials for silicone hydrogel contact lenses and monomers for foldable intraocular lenses (IOL).


The soft hydrophilic foldable intraocular lens is the latest generation of advanced materials. It has small surgical wounds, quick recovery and better biocompatibility. The two products whcih named PEA (CAS#: 3530-36-7) and PEMA (CAS#: 3683-12-3) provide the most reliable material support for a new generation of innovative products.

According to the hardness of the material, intraocular lenses can be divided into hard intraocular lenses (non-foldable intraocular lenses) and soft intraocular lenses (foldable intraocular lenses). Compared with hard intraocular lenses, soft intraocular lenses has the characteristics of small surgical incision, short operation time, fast postoperative recovery, and small visual deviation.

Rigid intraocular lens PMMA is the first material used to make intraocular lenses. It has been used in clinics for a long time, and its clinical effects have been fully verified. The price is cheap, but the surgical incision during implantation is relatively large, generally about 6 mm . Due to the expansion of the incision, sutures must be added to ensure the watertight state after the operation, so that the suture pulling is prone to postoperative astigmatism, and the vision recovery is not ideal. The larger the incision, the greater the postoperative astigmatism. At the same time, due to the large incision, the postoperative recovery time is longer, which increases the hospitalization burden of the patient.

The feature of soft intraocular lens is that it is foldable, so the incision during implantation is small, generally 2~3mm. At present, micro incision implantation is more popular, which has less tissue damage, reduces astigmatism caused by surgery, and improves postoperative response. The postoperative response is lighter and the recovery is faster. At the same time, the seamless thread technology saves operation time, avoids postoperative local suture irritation to tissues, and reduces postoperative discomfort and other adverse reactions of sutures.

The soft hydrophilic foldable intraocular lens not only has good mechanical and optical properties, but also good elasticity and hydrophilicity. Its relatively hydrophilic crystal surface has excellent tissue compatibility and good flexible surface. The surface of the lens will not change and damage during the folding and implantation process, which can reduce foreign body reactions.
