Endo Optiks was established in 1991 and is the leading medical device company specializing in microendscopy for Ophthalmology. Endo Optiks proudly manufactures its devices and endoscopes in the United States and has worldwide representation and distribution.

The core products are the E2 laser and endoscopy system (Diode laser, Video Camera, Xenon Light) and the E4 endoscopy system (Video Camera, Xenon Light) with endoscopes offering a variety of sizes, resolution and viewing angles. All endoscopes are autoclavable. Patented triple function endoscopes incorporate video imaging, illumination and laser delivery through microendoscopes less than 1mm in diameter providing a unique tool for minimally invasive ophthalmic surgery for a host of eye diseases and conditions. The most common use of endoscopy in ophthalmic surgery is for the treatment of glaucoma, retinal diseases and other applications such as foreign body removal and simply visualizing areas of the eye, otherwise inaccessible.

Glaucoma:

Endoscopic Cyclophotocoagulation or ECP is an elegant technique that reduces the over production of aqueous fluid by applying laser energy to the ciliary processes, thereby disabling the epithelial layer of the process. Over 100,000 ECPs have been performed worldwide and studies have shown it to be one of the safest glaucoma procedures available. It is most commonly performed at the same time as cataract surgery. The endoscope is inserted into the same incision as the cataract surgery and up to 360 degrees of the ciliary process are treated with the laser beam in the endoscope.

Retinal Applications:

There are many applications for the retinal surgeon because the intraocular endoscope permits imaging, illumination and laser treatment for surgeries that would otherwise be very difficult or impossible or to perform because of limited or no visibility or access. Visualization with the endoscope is essential if the anatomy or pathology is not visible through the operating microscope. Many surgical procedures are endoscopically monitored such as vitrectomy, lensectomy, membranectomy, and more. Surgery for complications of diabetic retinopathy is managed. Detection and removal of lens remnants, foreign body, and trauma are all treated with endoscopy.
