12.5mm Posterior Chamber Intraocular Lens For Glaucoma

Hydrophilic Acrylic Posterior Chamber Intraocular Lens for Cataract Surgery

Intraocular lens (IOL) implantation is the standard of care for treating aphakia when spectacle or contact lens correction is not viable. There is considerable controversy about the relative efficacy and safety of the different IOL implantation approaches, as well as their indications. Since the development of the modern, open-loop anterior chamber IOL (ACIOL) and the re-emergence of the iris-fixated claw IOL, ACIOL implantation for aphakia has regained popularity. However, the posterior chamber IOL (PCIOL)--namely, the capsular-supported PCIOL and, in the absence of capsular support, the iris-sutured or transsclerally sutured PCIOL--offers numerous advantages for certain patients. By virtue of their anatomic location in the eye, capsular-supported or sutured PCIOLs are appropriate for patients with glaucoma, diabetes, cornea guttata or low endothelial cell count, peripheral anterior synechiae, or known or suspected cystoid macular edema. They may also be appropriate when the patient with aphakia is young and has a relatively long life expectancy. The sutured PCIOL procedure--specifically, the transsclerally sutured PCIOL procedure--is far from benign, however, and surgical expertise is an important consideration. Recent surgical and technological advances, including the technique of burying the suture knot in sclera, use of an ab externo suturing approach in the normotonic eye, and the use of intraoperative endoscopy, have improved the accuracy of the transsclerally sutured PCIOL technique. Additional advances, including diagnostic ultrasound biomicroscopy and small-incision surgery with foldable, transsclerally sutured IOLs, may further improve patient management and clinical outcomes.

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.

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.

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.
