Capsular Ring dimensioned and calibrated to stably occupy the equator of the lens without having any residual elastic forces in the ring itself since it is a whole ring that reaches its final dimensions just when is expanded in the capsular bag. The ring has a continuous outer edge and two margins one lower and one upper, which delimit a groove that serves to house the haptics of the intraocular lens. The upper and lower edges have holes that promote adhesion of the capsule and the surgical implantation maneuvering.
The ring is sized in order to keep separated the anterior capsule from the rear and prevent the migration of the equatorial cells (LEC) from the anterior to the posterior capsule. The hollow of the ring constitutes a natural place to improve the spontaneous slip of the haptics of the IOL, the centered positioning, a solid anchorage to avoid tilting or inclinations of the IOL with respect to an ideal plane, orthogonal to the axis of vision inside the capsular bag.

We used different material from PMMA (or silicone) realizing totally acrylic material as in the vast majority of intraocular lenses.
The acrylic material allows us to have a device easy to handle and easy to implant via the same injectors that are used for the acrylic IOLs. Biocompatibility and safety are guaranteed by years of experience with the same material used for the intraocular lenses, normally housed in the capsular bag, carrying out a similar but incomplete action, with their haptics portion in respect than that exerted by the SALring.
SALring can be injected into the capsular bag with standard injectors from 2.25 mm to 1.8 mm (choice of the surgeon).
The external diameters available are 10.6, 10.8 and 11mm. the interior hollow allows implantation of most intraocular lenses on the market. The thickness antero-posterior is maximum 1mm.
SALring sizing
The size of the ring has been evaluated, both theoretically and creating models of various sizes, on pig eyes.
