The OS 4 in cataract surgery - more than a phaco machine
The OS 4 utilises the laws of physics with the aim of making cataract surgery fast, safe and calm. The easyPhaco technology is developed for safe and efficient phacoemulsification. On account of HF capsulotomy, capsulorhexis has been given a gentle method of capsulotomy.
Cataract techniques with the OS 4 device
Capsulorhexis
Capsulorhexis has marked a significant milestone in the development of cataract surgery. The capsular bag can be cut open using high-frequency energy – entirely without the usual tearing by forceps or needles. It is sufficient to gently slide the capsulotomy tip over the tissue, even under the iris, while applying the diathermy energy *. In standard phacoemulsification procedures, the anterior lens capsule is manipulated using a needle or forceps. However, in recent years, Femto laser-assisted capsulorhexis has gained increasing importance. Oertli has successfully taken another path – using HF capsulotomy, developed in collaboration with Professor Rudolf Klöti, Zurich.

Phaco with the OS4 machine
Cataract surgery is one of the most common surgical procedures performed worldwide. The gold standard for cataract treatment is phacoemulsification, often referred to as phaco. A small tunnel incision is made in the cornea, which usually closes on its own after the operation. A hollow needle is inserted through this incision, and ultrasonic energy is used to emulsify the lens nucleus, which is then aspirated. For this procedure, Oertli provides the easyPhaco technology, developed for safe and efficient emulsification.

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).

Diathermy
Diathermy is used in manifold ways in cataract surgery and can be a gentle alternative to capsulorhexis and forceps, particularly for capsule opening. Oertli's surgical platforms enable finely and directly controlled dosing of high-frequency energy.
