Hydrophilic Acrylic Foldable Intraocular Lens 26% Water Contents

Hydrophilic Acrylic Foldable Intraocular Lens with Water Contents 26%

Hydrophilic foldable acrylic is a combination of hydroxyethylmethacrylate (polyHEMA) and hydrophilic acrylic monomer [26] material and it was introduced in 1980 with several modifications since. The IOLs made of this materials are usually single pieced and designed for capsular bag implantation. Refractive index of the material is 1.43, with water content ranging from 18 to 34% .

They are soft, compressible with excellent biocompatibility for its hydrophilic surface. They can be implanted through a small incisions, lower than 2 mm and therefore ideal for MICS . The folding of poly-HEMA chains depends on the level of hydration, and so the physical and optical properties of the polymer change as a function of water content. As the lenses hydrate, they absorb water and become soft and transparent.

Hydrophilic Acrylic Foldable Intraocular Lens with Water Contents are copolymers of HEMA and PMMA, with water contents of 26%, and are much more resistant to deformation and opacification.

Indications:

1. Cataract on both eyes.
2. Cataract of single eye in patients, who is unwilling or unfitful to wear corneal contact lens
3. Aphakic eye caused by various reasons

Instruction for Use

1. Examine the type, diopter power, size, the period of validity indicated on the outside package label. DO NOT USE if the expiration date has passed.
2. Take out the tyvek pounch and check that there is no damage on it, verify that lens power, size, type on the vial are same with the data on the outside label.
3. Open the pounch under the aseptic place, open the lens case after final confirmation of lens model and diopter power, take out IOL very carefully and implant IOL into eyes.
4. Rinse the IOL with infusion solution or the equivalent.

Precautions

1. Do not use the One-piece Posterior Chamber Foldable Intraocular Lens if it is after expiration date.
2. Do not try to re-sterilize the One-piece Posterior Chamber Foldable Intraocular Lens.
3. The surgeon must be the person who had observed and assisted IOL implantation surgery many times, must be also the person , who has been ophthalmologist with rich experience and independently completed the IOL omplantation successfully for at least one time.
