The CataRhex 3 in cataract surgery

The CataRhex 3 is designed with the goal to make cataract surgery quick, safe, calm and, thanks to its exceptional mobility, accessible everywhere. The space-saving and portable surgical platform enables cataract surgery in modern high-performance operating theatres and under difficult conditions or special circumstances.


In the development of cataract surgery, capsulorhexis created a milestone. It leads to greater safety in interventions and reduces the risk of radial capsule ruptures significantly. Work on the anterior lens capsule with needle or forceps is still regarded the standard procedure in phaco interventions. However, the Femto laser assisted capsulorhexis has gained increasing importance in the last few years. Oertli has successfully taken another path – using Bipolar capsulotomy developed in joint collaboration with Professor Rudolf Klöti, Zurich.

Cataract surgery is one of the most frequent operative interventions in the world. Phaco – phaco emulsification –  is the golden standard for an operative treatment of cataract. A small cut into the cornea (scleral cut) is performed, which closes itself again after the surgery. A cannula is inserted into the cut. Then, the lens is reduced to small pieces with ultrasound energy, and aspirated afterwards. With its easyPhaco technology, Oertli has taken phaco to an entirely new level – ensuring a stable anterior chamber, direct fragment followability and a smooth fragment aspiration.

Irrigation / aspiration

With irrigation and aspiration instruments, the supply of irrigation fluid and the aspiration of lens material can be combined directly in one work step. Oertli offers I/A instruments and tips with a Safety Design, which together with the SPEEP pump are an ideal combination for the removal of lens material (cortex).

The bipolar diathermy function of the CataRhex 3 has a number of applications such as the unique capsulotomy technique. Handpieces and the easy to attach tips are manufactured from high-quality titanium.

Anterior vitrectomy

In anterior vitrectomy, the vitreous body content is removed, and generally, a replacement fluid is inserted. The procedure is used, for instance, in the case of a loss of lens fragments in the vitreous body following a posterior capsule rupture. In such cases, Oertli brings to bear the advantages of both physics and fluidics in a highly impressive manner – safe and traction-free.
