what is the device used called for eye laser surgery and do you know which company use it
What kind of eye surgery are you talking about? There are many kinds. The most common is for improved focusing of the eye, which reshapes the cornea. It is often referred to as Lasik surgery. There are other kinds that operate inside the eye. I am sure nthat a Google search of 'laser eye surgery' will provide many references
Here is one reference to get you started:

I believe lasers can also be used to reattach retinas, but am not sure.
The device commonly used for eye laser surgery is called an excimer laser. It is a type of laser that emits ultraviolet light and is used to reshape the cornea to correct vision problems such as nearsightedness, farsightedness, and astigmatism.
Many companies manufacture excimer lasers for eye surgery, but one of the most well-known and widely used brands is VISX by Johnson & Johnson. VISX excimer lasers have been used for decades and are known for their accuracy and safety in performing corrective eye surgeries. Other popular brands include Alcon, Nidek, and Bausch & Lomb, all of which offer their own models of excimer lasers for eye surgery.
To find the specific device used by a particular eye surgeon or clinic, it is best to contact them directly or research their website to inquire about the brand and model of the excimer laser they utilize for eye laser surgery.
