Aspherical Foldable Intraocular Lens

Aspherical Hydrophilic Acrylic Posterior Chamber Foldable Intraocular Lens

To avoid the complications associated with anterior chamber intraocular lenses (IOLs), we have developed a technique for the implantation of a posterior chamber IOL in the absence of capsular support. The IOL is secured in the ciliary sulcus by suturing the haptics to the sclera at the ciliary sulcus inferiorly and to the sclera or iris superiorly.

Product Parameters:

According to different lens surface designs, cataract intraocular lenses can be divided into spherical and aspherical intraocular lenses. The visual imaging effect of aspherical surface is better than that of spherical surface. The reason is simply that the light cannot converge to one point when passing through the spherical lens, causing "aberration" of central vision and peripheral vision. Aspherical lens can overcome it well.So, compared to Spherical IOL, the Aspheric IOL can imporve contrast sensitivity in mesopic, photopic and dim light conditions to imporve quality of vision. 

Use procedures:
a. 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.
b. Take out the TYVEK pouch 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.
c. Open the pouch under the aseptic place, open the lens vial after final confirmation of lens model and diopter power.
d. In accordance with folder holder instruction for use take out holders and implant IOL.
e. Rinse the IOL with infusion solution or the equivalent.

Aspherical Hydrophilic Acrylic Posterior Chamber Foldable Intraocular Lens adopts the world's top hydrophilic acrylate material from Contamac UK, which has excellent material uniformity, good biocompatibility, smooth surface, low silicone oil adsorption rate, bacteria and other sediments are not easy to adhere, no calcification and glistening. The Modified "C"Loop design provides excellent stability for the intraocular lens in the capsular bag, avoiding eccentricity, tilt, and anti-capsular contraction to the greatest extent.
