Introduction:
Intra-stormal implants or Intracorneal Rings, Segments or ICRs were designed and developed to be used as
a correction for reducing or eliminating myopia of -0.5 to -8.0 diopters.
They are also used for the correction of keratoconus if properly implanted into the stroma of the cornea,
outside of the optic zone.

Intra-stromal segments are now becoming a normal tool in the surgeon's arsenal against poor vision.
Unlike the original segments that necesitated the surgeon purchasing a multi-thousand dollar piece of
equipment and special instrumentation, products like KERATACx™ can be used by most surgeons without
expensive instrumentation.
Improvements in Pachymetry and corneal topography have increased the use of intra-stromal segments,
intracorneal rings or implants.

The implant changes the surface shape of the cornea following implantation because they are implanted
approximately 2/3 of the way into the periphery of the cornea thru a small radial incision and tunnel
created in the stroma.
The tunnel or elongated pocket can be created by using an manual instrument or a laser following the wound
puncture, which must not be to deep so as to perforate the cornea. Once formed, the implant is carefully
inserted into the tunnel and the shape of the cornea is changed so as to create better vision for the patient.

The amount of correction depends upon the thickness of the implant and they are designed to be used in pairs.
They may be implanted in a clockwise or counter clockwise direction depending on the intra-stromal tunnel and
surgical technique due to the hole at each end. This hole may be used for manipulation and removal.
Opposed to other intra-stromal inlays, the optical zone of Keratacx™ is 6.2mm.,
which tend to a slightly higher correction

Reducing or eliminating Myopia of -0.5 to -8.0 diopters
The design of KERATACx allows for their extraction from either end and replacement if necessary. They are
transparent and each ring covers 160º degrees.
They are manufactured from the world’s finest PMMA and are currently available from
150 microns to 500 microns in 25 micron increments.
