Spherical Hydrophilic Acrylic IOL for Cataract Surgery
The Spherical Hydrophilic Acrylic IOL for Cataract Surgery is optical implant, which is made from hydrophilic acrylate
material (copolymer of HEMA and MMA).This product is suitable for
implantation to correct the vision of aphakic patients after
clinical cataract extraction.
The Spherical Hydrophilic Acrylic IOL 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.
Characteristics of Spherical Hydrophilic Acrylic IOL for Cataract
Surgery
1. Material: High purity Hydrophilic Acrylic with good toughness
and tensile strength, The material is proven to have excellent
biocompatibility to reduce operation trauma and post operation
inflammation.
2. The lens is YAG laser compatible with fine optical transmittance
and UV absorbing ability.
3. The lens has good unfolding time without impaction on capsule.
4. The lens has excellent centering ability and stability.
5. The lens is stored in the Lens Holder Folder securely, which can
be folded by the Lens Holder Folder without the folding tweezer
(please find the usage in the photos below) . The lens also can be
implanted by injector with proper size.
6. The lens has excellent memory to guarantee the exact unfolding
in the capsule.
