Technology

Norwich Ophthalmology Group continues to embrace the latest in surgical skills and technology as envisioned by its founders more than 30 years ago.

Our offices are equipped with the latest in technology to provide a wide array of services, such as computerized corneal mapping systems for cataract, glaucoma and vision correction surgery, specialized diagnostic and measurement devices, in-office lasers for treating a variety of conditions including diabetes, macular degeneration and glaucoma, and specialized testing for macular degeneration, diabetes and other ocular diseases.

As the Laser Surgery specialists, we utilize cutting-edge lasers and surgical techniques to provide you with the best possible visual results. In fact, we have five different types of lasers in our offices alone! Norwich Ophthalmology Group stays at the cutting edge by committing to new technology that is proven to be the best and safest alternative. We perform only those procedures that have shown high levels of success by using the most advanced technology available while exposing patients to the lowest possible risk.

Allegretto-Wavelight-Laser

Allegretto Wavelight Laser

ALLEGRETTO WAVE’s revolutionary approach to laser vision correction minimizes problems associated with older generation lasers, such as night vision reduction, glare, and halos. The success of the ALLEGRETTO WAVE can be directly measured by our patients’ remarkable improvement in visual acuity and low occurrence of side effects. Smart energy control and eye tracking technology combine to provide an ultra-fast solution to laser vision correction. Innovative and redundant safeguards make ALLEGRETTO WAVE a leader in the field.

laser-trabeculopalsty

Argon Laser Trabeculoplasty (ALT)

An argon laser can be used to widen the openings in the drainage system, thereby lowering the pressure. This medical laser treatment called Argon laser traceuloplasty, is normally safe, painless, quick and is performed in our office. The Argon laser is also used extensively in the treatment of detrimental changes in the retina (the film of the eye) secondary to diabetes. This often labeled as Focal coagulation for CSME and Pan-retinal photocoagulation for Proliferative Diabetic Retinopathy. For more information, click here for more information

Cirrus-HD-OCT

Cirrus HD OCT

Norwich Ophthalmology Group can now provide an even more thorough examination and diagnosis of your retina than ever before with the STRATUS™ OCT and Cirrus™ high-definition OCT. These cutting-edge diagnostic systems allow our doctors to get a complete cross-sectional or 3-dimensional view of your retina using an optical measurement known as low-coherence interferometry. The technology is much like ultrasonography, except that OCT uses light instead of sound to generate images. These units scan an infrared light across the retina, which produces retinal images of microscopic quality. They can measure distances as small as 0.05 millimeters and collect over 27 million data points per second! This allows us to view your retina in previously unobtainable detail, enhancing our ability to diagnose and manage a wide-range of retinal disorders, including diabetic retinopathy, macular degeneration, ocular histoplasmosis, central serous retinopathy, macular pucker, and macular holes.

HRT-II-or-Heidelberg-Retinal-Tomography

HRT II or Heidelberg Retinal Tomography

The HRT II uses an imaging method called “confocal laser ophthalmoscopy” to scan the retinal surface and optic nerve with a laser. It then constructs a topographic three dimensional (3-D) image of the optic nerve and measures the thickness of the retinal nerve fiber layer. These are very precise measurements that your eye doctor will interpret in conjunction with the other Glaucoma tests at your examination. Back to Top
Pentacam2

Pentacam HR

In our opinion the Pentacam HR is the ultimate diagnostic tool for laser vision correction surgeons. It utilizes a sophisticated Scheipmflug camera system that scans the anterior eye (cornea, anterior chamber, iris, and lens) and takes up to 25,000 measured data points in a scan time of 2 seconds per eye. From all this data a 3D model of the eye is constructed that can be viewed and analyzed by the doctor. The data collected allows us to view the eye from 25 different angles with a three dimensional analysis of all the structures mentioned above. Most importantly for potential laser vision correction patients it allows us to have a precise elevation map of the back surface of the cornea unparalleled by any previous technology. This information helps us to make sure the recommendations we make for laser vision correction will be as safe as possible. The 3D capability of the image allows us to see if lens implants for very near or farsighted patients might be a better option than laser surgery. We can also grade the level of cataract development in the lens of the eye and follow its progress with subsequent scans. For patients who have undergone previous laser vision correction who are now or at some time in the future will be in need of cataract surgery, we are able to more accurately calculate the lens implant replacement power with the true corneal curvature measurements (keratometry readings) that are provided by the Pentacam.

Yag-Laser

Yag Laser

Modern cataract surgery techniques successfully restore vision and help to improve the quality of life for the great majority of patients. Sometimes, months or years after cataract surgery, vision can once again become cloudy. Activities like reading, driving and watching television slowly become more difficult. This can be due to a condition known as opacification of the lens capsule. The lens capsule is the normally clear structure that holds the intraocular lens in place. If the lens capsule becomes cloudy it will block a clear picture from passing though the pupil of the eye. An opacified lens capsule can occur in about 30% of patients who have cataracts removed. YAG laser capsulotomy is a simple and very safe outpatient procedure to open a cloudy lens capsule. Only anesthetic eye drops are necessary and the treatment takes just a few minutes. Most people notice improvement in vision within a single day. Occasionally eye pressure may rise as a result of the laser energy. For this reason we monitor our patients for about an hour after the treatment. There is also a very rare risk of retinal detachment and the doctor will check your retina about a week after the procedure. Once a cloudy lens capsule is opened by the laser, the condition typically cannot recur and the restored vision can be considered permanent. Back to Top
iol-master3

Zeiss IOL Master

Norwich Ophthalmology Group uses the Zeiss IOLMaster, the first device that quickly and precisely measures boundaries for intraocular lens (IOL) implantation without ever touching the cornea. If a patient’s natural lens of the eye is removed, due to cataracts or vision correction purposes, an IOL is then implanted into the eye. This IOL’s “power” or strength needed to give the patient good vision, has been very carefully calculated by the surgeons at Norwich Ophthalmology Group. Though the instrument previously used to take these measurements was accurate and dependable, the IOLMaster has highly refined this measurement. The IOLMaster is yet another technological advancement that Norwich Ophthalmology Group surgeons utilize to ensure high accuracy, which in turn equals superior post-operative visual outcomes.
