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.

Intraocular lenses are implanted during cataract surgery to replace the natural lens and improve vision. It's essential to discuss the various types of IOLs available and their respective benefits.

Spheric intraocular lenses (IOLs) are artificial lenses implanted in the eye, typically after cataract surgery, to replace the eye's natural lens. These lenses have a uniform curvature, which helps to focus light onto the retina, providing clear vision. Unlike aspheric lenses, which are designed to reduce spherical aberration and improve contrast sensitivity, spheric IOLs offer a simpler design and are often used for patients with standard vision correction needs. They can be monofocal or multifocal, depending on the patient's visual requirements.
In mine, tooth fillings, both mercury amalgam and plastic; and in my eyes, intraocular lenses. Plus the residue of several pharmaceutics.
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.

Some types of vision correction surgeries are, Lasik, PRK, Lasek, and Implantable/intraocular lenses. Of course, Each process has its own risks and benefits.
