Surgitel surgical telescopes have all the best and most advanced ergonomic features. Years of development through the study of ergonomic medicine, have created the Surgitel surgical telescopes. Their design, construction, and ease of use, make them the only choice for the serious surgeon. If you have diminished vision, you will suffer from chronic neck and back pain after surgery. This is indicated by being out of proper ergonomic alignment with your surgical field of view. When using zero degree or fixed angle visor magnifiers you are forced to bend your neck and back far beyond a normal and comfortable range. Surgitel surgical telescopes allow you to sit or stand in proper posture and use your eyes, not your back and neck to see your magnified surgical site. These telescopes can be fitted with your lens prescription if needed. Laser safe clip in lenses are also available for use during laser surgery. A complete line of lighting attachments is available as accessories to the telescopes. Lenses are available in 2.0, 2.5 and 3.0(near, far & extra far).Stronger magnifications are also available.
