Cataract surgery is the removal of the natural lens of the eye (also called crystalline lens ) that has developed an opacification, which is referred to as a cataract.

Sort of crystalline.

Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision.

What does that convex lens do?

With binoculars and a longfocus lens.

The presence of carbon allows steel to assume one of several different crystalline configurations.

Separation of solid, crystalline matter from a solution, or the liquid or gaseous phases.

I had never seen the inherent challenge of communication in so crystalline a light.

Surgical treatments that reshape the cornea, such as PresbyLASIK and conductive keratoplasty, are also worth consideration, but some use of reading glasses will still remain when light is poor or when reading for extended periods of time, since such procedures do nothing for crystalline lens deterioration.
