Back to the history The invention of an intraocular lens came from a genuine observation made by the English ophthalmologist Sir Harold Ridley that PMMA fragments from the cockpits of the windshields of airplanes were will tolerated inside the anterior chambers of the injured pilots during the world war II without causing much complications.He then designed a biconcave PMMA (polymethylmethacrylate) lens and implanted it in the posterior segment of a female patient after performing extra capsular cataract extraction.The Acrysof Toric IOL is manufactured by Alcon laboratories.
The silicon design ensures greater optical performance due to higher quality and fewer aberrations compared to acrylic lenses.Thanks to Sir Harold Ridley, the inventor of the first synthetic lens implantable inside the human eye, that misery is no longer a horrible option to consider for cataract patients.The following lines will take you in a journey to the fantastic world of IOLs tracing the historical beginning till the modern revolution in the design and capabilities of modern IOLs.This type of IOL is capable of correcting one type of refractive error only at a time; either nearsightedness, or farsightedness.

The main disadvantage of this type of IOL is that they are not able to restore the accommodative power of the normal crystalline lens which enable humans to see far objects as well as near ones.This means better recognition of various objects under low light conditions.
