A Constant 118.2 PMMA Intraocular Lens Modified C Loop

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%.
