desires to serve our mutual patients they make use of the latest improvement in technologies, both in the medical and surgical fields. The following instruments use the latest technology. Some of these instruments are only found in Central Oregon at the Eye Surgery Institute. Click on one of the following terms below to learn more about our technology:
OCT/SLO
The Redmond office features the OCT/SLO. Our machine was only the fourth of its kind in the entire USA. We are the only physician office to possess this technology in Central Oregon, and probably the state of Oregon. This advancement allows us to virtually get inside your eye and take high resolution photographs so your eye physicians can better understand what’s happening in your eye. Better understanding leads to better treatment.
For the technically ambitious, the OCT/SLO abbreviation stands for Ocular Coherence Tomography/Scanning Laser Ophthalmoscope. It has the capacity to give multiple images of the back of your eye from one location, including: topographical map, tissue depth variance, and cross-section and horizontal pictures of the exact point in your eye in the same frame.

Octopus, Visual Fields Testing
This state of the art machine analyzes visual fields. A visual field is how much peripheral vision one has. This machine better detects and tracks any changes in the field of vision. It then utilizes sophisticated software to analyze any ongoing changes.
Fundus digital camera
The fundus of the eye is the back of the eye. This camera documents disease of the fundus and studies the effects of vascular disease on the eye (such as diabetes and macular degeneration).
HRT3
This is a sophisticated laser based instrument that helps to assess, diagnose and manage your glaucoma. The HRT provides a topographical map of your optic nerve, including the rim, cup, and retinal nerve fiber layer.
YAG Laser
After cataract surgery, a cloudy membrane can develop behind the lens implant. This cloudy membrane can make the vision blurry. A YAG laser opens a small window in this membrane so the vision can be clearer.
EyeMaginations
EyeMaginations is an educational tool that has been a real blessing in educating patients and staff. This “three dimensional” representation of the eye, eye procedures, and eye conditions has very understandable explanations and great graphics. Click here for more information.
EndoCycloPhotocoagulation, ECP
ECP is new technology using fiber optics that is proven to reduce pressure in glaucoma patients.
Fluid in your eye, called aqueous humor, is constantly being produced. Its function is to nourish the cornea and the lens and then drain out. If the “drain” gets clogged, the fluid builds up, causing pressure. This pressure is called glaucoma. This increased pressure pushes your optic nerve and makes the nerve not transmit normal levels of input to your brain. The result is that you don’t have as much vision. If left untreated, glaucoma can lead to optic nerve damage and loss of sight. In the past, eye drops have been the only treatment to try to avoid the “clogging” effect of your eye’s drainage system.
Now, with this new technology, we can place a tiny probe that contains a tiny light source, a fiber optic. The fiber optic delivers laser energy. The laser seals off some of the fluid producing cells in the eye, so not so much fluid is produced. Statistically, 80% of patients can either stop their glaucoma drops altogether or greatly reduce them.
Whether or not you are having cataract surgery, this new technology can help you manage your glaucoma.
IOL Master
This state of the art machine measures the length of your eye, a number your cataract surgeon needs in order to implant the correct power lens after he removes the clouded cataract material from your existing lens. A similar measuring machine of your eye is the A-scan, which measures to within .10 to .12 mm of accuracy. The IOL Master measures to within .02 mm of accuracy, which is 5-6 times as accurate. Advanced technology means a lesser chance of receiving a lens that is not the most accurate refraction.
A and B Scan
These two scans involve an ultrasound of your eye. The ultrasound uses high-frequency sound waves that travel through the eye. Reflections (echoes) of the sound waves form a picture of the structure of the eye. The size of the eye and any structures in the eye can be measured. This picture helps the physician see more clearly what’s in your eye, especially if you have cataracts or any other condition that would prevent the physician from getting a good view of your eye.
Some of the situations this testing machine might show would be retinal detachment, foreign bodies in the vitreous, tumors, vitreous hemorrhage, and other conditions that would need further attention.
Fluorescein Angiogram
Eye Surgery Institute is proud to feature the best technology offered in the arena of fluorescein angiography with the addition of the Heidelberg imaging system in the Bend office. Fluorescein is the type of dye that is used. Angiography is the study of the blood vessels. Using these two features, the doctor can “light up” the interior of your eye and take a picture of it. This technology is an extremely valuable test that provides information about the circulatory system and the condition of the back of the eye. It is used primarily in the diagnosis of macular degeneration and diabetic eye disease.
The test is performed by injecting fluorescein into a vein in the arm. In just seconds, the dye travels to the blood vessels inside the eye. A camera equipped with special filters that highlight the dye is used to photograph the fluorescein as it circulates though the blood vessels in the back of the eye. The dye and special photography reveals if there are any circulation problems, leaking or abnormal blood vessels. If a problem is diagnosed, the doctor can then determine treatment options.
Cirrus HD-OCT
The Bend office offers the Cirrus HD-OCT. The Cirrus is the newest development in cross-sectional imaging of the retina. ‘HD’ stands for high-definition. The previous OCT models achieved a resolution of 8-10 microns; now, the HD-OCT offers a resolution of 5 microns. This improved imaging ability allows the physician to diagnose very subtle macular disease, which was previously unrecognizable.
