Best Answer

The process involves the production of a cylindrical mould with a high fracture toughness containing a rigid pin in the centre. This technology is highly advanced and accurate using computer and precision mechanics.

A mixture of polymer matrix and solid particles are introduced into the mould surrounding the rigid pin. Once the mould has been filled an ultrasonic energy is applied to the mould and polymer mixture. After a specified time under the influence of the ultrasonic radiation the polymer cures and solidifies. Heat is then applied to further cure and harden the polymer mixture inside the mould.

Why should you not use Timolol eye drops with contact lenses?

Contact lenses can absorb the medication and decrease the amount of timolol entering the cornea. This will affect the intraocular pressure by potentially increasing it, thereby putting the eye at a higher risk for glaucoma progression.
