- about us
Our advanced manufacturing technique delivers excellent optical quality for a reasonable price.
Katena sells both reusable and single-use lenses. The single-use lenses are sold in boxes of 10.
All lenses commonly used for lasering have the necessary coatings including an anti-reflection coating.
No. All lenses that are appropriate for laser procedures have the proper coatings.
No. Single use lenses are not supported for reuse.
No. The reusable bi-aspheric lenses are non-contact lenses designed for use in the clinic. A lens cloth is supplied to remove dust and fingerprints. Per the Instructions for Use (IFU), the lenses can be cleaned with mild soap and water if required.
The materials used for the optics of our lenses are not designed for heat sterilization and will deform if autoclaved. The use of harsh chemicals or abrasive cleaners will deteriorate the optic’s coatings and mirrors.
All methods of cleaning have some environmental impact, whether the lens is single use or reusable.
Yes. Our surgical gonio prism (K30-1405 for use in left hand, K30-1400 for use in right hand) lens is the equivalent to a Swan-Jacob lens.
The material for the optics is PMMA. This material is lighter than traditional glass lenses.
