PMMA Intraocular Lens
The true beginning of the IOL is the Second World War. Against a
backdrop of the Battle of Britain, where aircraft fought for air
supremacy in the skies over the south of England, Harold Ridley was
a civilian ophthalmologist who operated on Royal Air Force pilots
with eye injuries. On August 15, 1940, inspiration stuck. A pilot’s
Perspex canopy had shattered, sending numerous splinters of
poly(methyl methacrylate) into his eyes. Ridley performed a total
of 19 operations on the pilot, saving the vision in one eye. During
the process, he realized that the body’s immune system had not
reacted against the PMMA splinters; unlike glass splinters, they
remained inert in the eye. Ridley recognized that this material
could be used for artificial lenses, and that these could be
implanted into the eye to replace the natural lenses removed during
cataract surgery.

PMMA Intraocuolar Lens can be used to correct the vision of aphakia
eyes either in the primary and secondary surgery under the option
of the surgeons. PMMA Intraocular Lens can be implanted into the
capsule bag.

Design features:
1- The IOL produced by our company is made of PMMA, allowing the
good flexibility of the loops,which can be bent to the optical part
of the IOL, making the IOL implanted easily inside the capsular
bag.
2- The 10°angle of the haptic allows the lens to have a complete
contact with the posterior side of the lens capsule.
3- The thin edge of the IOL reduces the edge glare in a large
degree.
4- The haptic are designed to maintain stability of lens implant in
the eye, which keeps the IOL centered in the optical field.
5- The IOL produced by our company can filter the ultraviolet rays
effectively, and the rate of the visible light is greater than 90%.
