Why choose Barron Artificial Anterior Chamber Maintainer?

The innovative Artificial Chamber Maintainer is used in conjunction with the Barron Vacuum Trephine for creating either lamellar or full penetrating corneal grafts, providing the utmost levels of quality to your procedures. By utilizing the combination of both products, a healthcare professional can cut the donor cornea from the epithetial side, creating an angle of cut that more closely aligns with the angle of cut created by the trephine and reduces the risk of surgically induced astigmatism.

The Artificial Chamber Maintainer has two ports with pinch clamps for infusing viscoelastic, BSS or air to recreate the natural curvature of the cornea. Viscoelastic is used to protect the endothelial cells on the underside of the cornea.

  • Designed to hold a 14–18mm diameter scleral rim in place during corneal surgery
  • Bright blue color provides a contrasting background for visualization of the cornea.


*Stainless steel base supplied separately on code K20-2126

Why choose Barron Donor Punches?

We offer state-of-the-art Barron donor punches, meticulously designed for precision in corneal surgeries, cutting the donor cornea tissue for corneal transplant procedures.

The open-top design enhances visualization of cornea placement in the cutting block, while the four steel guideposts at the corners guarantee accurate alignment to the center of the donor cornea. Plus, with four small holes in the base of the cutting block that can be inked, identifying the four quadrants of the cornea for suture alignment has never been easier. Experience precision in your corneal procedures with our innovative donor punches.

Why choose Barron Radial Vacuum Trephines?

Our radial vacuum trephines are designed to provide additional stability and accuracy between the outer suction ring and cutting trephine blade by using radial suction chambers. The 16 radial chamber dividers leave a symmetrical pattern on the anterior corneal surface that can be subsequently dried using a cellulose sponge and marked with a sterile gentian violet marker marked to support even suture alignment. They also boast a smooth rotating mechanism which advances the blade 250 microns per full rotation, while fine cross hairs provide accurate alignment with the visual axis for the recipient.

  •  Available in 11 sizes ranging from 6.0mm to 9.0mm.
  •  Provided fully assembled and sterile single packed, ready to use.
