ISO Cataract 30D Posterior Chamber Intraocular Lens

Hydrophilic Acrylic Posterior Chamber Intraocular Lens for Cataract Surgery

Hydrophilic Acrylic Intraocular Lens for Cataract Surgery 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.

Intraocular lens (IOL) is a lens implanted in the eye as part of a treatment for cataracts or myopia. If someone has a natural lens in the eye it is known as phakic and if someone has an artificial lens in the eye it is known as pseudophakic or false lens. These are implanted during cataract surgery, after the cloudy eye's natural lens (colloquially called a cataract) has been removed. The pseudophakic IOL provides the same light focusing function as the natural crystalline lens.

The Hydrophilic Acrylic Lens for Cataract Surgery 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

The Hydrophilic Acrylic Lens for Cataract Surgery Working principle
The human eye works like a camera, and our natural lens is equivalent to the camera lens, which plays an important role in collecting light. The lens of a normal person is transparent and gradually becomes cloudy with the increase of age, namely, “the lens becomes turbid", which refers to cataract. The cataract surgery is to remove the "cloudy lens". If the lens of an eye is removed, this eye is called aphakic eye, which is equivalent to about 1100 degrees of hyperopia and makes it impossible to see objects in the distance and nearby. It likes a camera with no lenses and needs to be optically corrected. Ordinary glasses are thick and heavy with poor optical effect, and are not suitable for one eye to wear. In order to compensate for the lack of refractive power of the aphakic eye, the intraocular lens must be worn to replace the "real lens" with “intraocular lens", so that cataract patients can have normal visual acuity after surgery. The intraocular lens consists of an optical lens and a support attached thereto. The intraocular lens is implanted in the position inside the eye where the natural lens is located and plays a role of collecting light. It is an ideal substitute that best meets the optical needs of the human eye.

The Hydrophilic Acrylic Lens for Cataract Surgery is optical implant, which is made from hydrophilic acrylate material (copolymer of HEMA and MMA). The material has excellent tough performances and tensile to keep nature moderate dehydration time, while the material has fine biocompatibility to reduce operation trauma and post operation inflammation. The Foldable Lens has good toleration to YAG laser with fine light transmission and UV absorption. The lens has perfect unfolding time without impaction on capsule. The lens has excellent centering ability and stability. The lens is stored in the Lens Holder Folder stably. The lens has excellent memory to guarantee the exact unfolding in the capsule.
