One Piece Posterior Chamber Foldable Lens
One Piece Posterior Chamber Foldable Lens 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.

One Piece Posterior Chamber Foldable Lens 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.
