Cataract surgery

The effect of cataract

What is a cataract?

Cataract is the most common reason for visual impairment worldwide. It usually affects people aged over 50+ but may also occur due to trauma, radiation exposure or be present from birth.  First signs people recognize are a blurred and cloudy vision, difficulty reading and a sensitive reaction to bright light in the night.

By severe visual impairment an improvement by eyeglasses is not possible anymore and a surgery is the last option to restore vision.

A turbid lens cannot be cured by medical treatment. Therefore a surgery is the only reasonable conclusion.


How is cataract surgery performed?

Since more than 30 years cataract surgery is the most performed procedure worldwide and in Germany more than 800,000 patients undergo surgeries without complications, too. Up to date emulsification and the extraction of the lens with ultrasound is the gold standard.

The opaque lens is removed micro surgically and replaced by a new artificial lens (IOL = intraocular lens)

Procedures are usually performed in local anesthesia and patients are able to regenerate afterwards in their familiar environment.  The surgery itself takes 10 to 20 minutes. Postoperative recovery period is usually very short and after a few days the patient can follow a daily routine. The final result – the optimal visual acuity – can be expected after 3 months at most.

What are the main advantages of the Nano Laser Cataract Surgery?

The CETUS is a totally new approach for cataract treatment. The lens is also chopped and removed but the main difference is the realization of doing. Traditional phacoemulsification is always linked to a high energy exposure to the eye and the created heat can lead to a loss of corneal cells (corneal endothelium) and edema. The relatively new laser technology offers the patient a very gentle alternative to ultrasound therapy. During the Nano Laser Cataract Surgery (NLCS) energy is released specifically and can be varied by the surgeon. Consequently thermal effects can be reduced to a minimum. A protection of the corneal endothelium and surrounding tissue is guaranteed as a result the healing process is more efficient and can be accelerated.

Safety has the highest priority during any surgical procedure, of course. In this particular field laser supported surgery has a very prominent feature:   The whole procedure with the CETUS includes single use material which means that every patient gets its individual equipment. The risk of infections and cross contaminations is reduced to a minimum. Especially patients with complicated eye diseases (Cornea Guttata, Fuchs Endotheldystrophy) or with reduced cell quantity are predestinated for this innovative technique to prevent inflammation and protect residual cell compartments.

The advantages:

-          Individual surgery

-          Short healing process

-          Minimized infection risk

-          Extremely slight energy exposure

-          Minimal influence to corneal structures

-          Minimized risk of capsular rupture
