OS 4 - the VITREORETINAL SURGERY device
The modern all-round vitrectomy device OS 4 is the first choice and sets new benchmarks in vitrectomy surgery in terms of functionality and quality. Thanks to the lance-shaped blade, the Caliburn Trocar System has a high cutting force and consequently reduces the penetration force into the sclera 1.The Continuous Flow Cutter ensures traction-free work and precise portioning of the vitreous body to be removed. In addition, a fully integrated endo laser is available, which can be controlled very easily via the multifunctional pedal.
Ophthalmic instruments and handpieces for ophthalmologists
Access
In vitreoretinal surgery, an essential requirement is a simple cannula system that ensures fast, flexible and safe work and best possible postoperative results. Oertli fulfils these requirements in an ideal way – with the Caliburn trocar system for OS 4.

Illumination
Illumination is of invaluable importance in ophthalmology. The choice of the right light source is decisive for achieving high-quality transscleral and intraocular illumination and simultaneously preventing phototoxic impacts and damages to the eye.

Vitreous body removal
A vitreous body removal ought to be performed in cases of diseases of the retina or the vitreous body, inflammations within the eye, or severe vitreous opacities. By removing the vitreous and replacing it with aqueous fluid or replacement fluid, seeing can be improved again. Oertli uses fluidics based on physics to support an efficient vitreous body removal.

Laser
With the integration of laser technology, eye surgery has made a significant stride forward. The laser is an efficient and gentle surgical method for a large number of interventions. As an all-in-one device, the OS 4 has an integrated endo laser – and thus a true laser function at the highest level.

Injection/extraction
You need to have optimum control of the infusion pressure for both injection and extraction. With the OS 4, the surgeon has control over the three-way-stop-cock at any time – as preferred, either via the pedal or via the touchscreen. Oertli also uses the advantages of physics and fluidics when it comes to injection/extraction – by creating consistent safety and user-friendliness.

Bipolar diathermy
Diathermy is used in manifold ways in vitreoretinal surgery and can be used to stop bleedings. Thanks to the cleverly thought out technology, Oertli surgical platforms have paved the way for extremely fine and directly controllable dosing of high-frequency energy. Therefore, applications of bipolar technology can be performed even more precisely and safely.
