  • Thermal Optimized Shot Distribution helps minimize the potential for thermal buildup.
  • Cross line projector provides precise centration.

The high-speed laser and eye tracker of this laser offers a unique combination of efficiency and safety, for faster throughput, reduced environmental exposure, and excellent outcomes. In addition, its proven, state-of-the art technology provides Dr. Roberts and the patient both safety and reliability, with a low rate of complications and re-treatments.

iTrace Wavefront Aberrometer/Topographer

iTrace Wavefront Aberrometer/TopographerNewest technology and better information allows Ophthalmologist Dr. Roberts at Shady Grove Ophthalmology to make better decisions, in turn, generates better results for patients! The new iTrace Aberrometer/Topographer uses technology that was developed from space and defense applications that is used to track satellites and missiles.  iTrace has adapted this technology to objectively measure the total refractive power of the eye. Using light rays, it detects where light rays land on the retina. Its software generates graphical displays of the visual performance of the patient’s eye. A complete analysis of their visual function is provided.

HD OCT Retinal Scans

Retina Scanning – The OCT scanner provides a high definition digital scan of the eyes retina. Each of the retina’s Cirrus HD-OCT 5000 - Shady Grove Ophthalmologydistinctive layers can be seen allowing Shady Grove Ophthalmologist Dr. Anthony Roberts to precisely map and measure their thicknesses. The scan is simple and noninvasive for the patient. The use of the high tech retina scanner can help the Dr. Roberts aid in early detection, diagnosis and treatment for retinal diseases and conditions including age-related macular degeneration and diabetic eye disease, and glaucoma.


Fundus Photography

Fundus photography is the creation of a photograph on the interior surface of the eye including the retina, optic disc,
macula, and posterior pole. Specialized equipment that consists of an intricate microscope attached to a flashed enabled camera are used in fundus photography. The patient sits at the fundus camera with their chin in a chin rest and their forehead against the bar. Dr. Anthony Roberts will focuses and align the fundus camera
and a flash of light appears as the he presses the shutter release, creating a fundus photograph. Dr. Roberts uses these retinal photographs to detect and evaluate symptoms of retinal detachment or eye diseases such as glaucoma.


IOL Master

Zeiss IOL Master 500 - Shady Grove OphthalmologyAiding in cataract surgery – This is the most sophisticated and accurate scanner to determine the power of the intraocular lens (IOL) implant for cataract and refractive lens exchange surgery. This optical scanner is innovative and trusted in the industry.  The IOL Master allows fast, accurate measurements of eye length and surface curvature, necessary for cataract surgery. Cataract surgery is more demanding than ever. Patient expectations are higher, which requires a more efficient streamlined scanner provides better clinical outcomes for cataract surgery patients. Our patients experience excellent results from our cataract surgery services.

Oculus Pentacam HR

Oculus Pentacam HR

This device is used for screening patient’s eyes and a quick Pentacam exam can aid Dr. Roberts in examining your eyes cornea. The Pentcam® HR camera captures up to 100 high-resolution images to provide a detailed analysis of the cornea. IOLs and pIOLs, corneal rings, corneal injuries and corneal opacities such as in Fuchs dystrophy are thus brought into view in brilliant detail. The crystalline lens is displayed from anterior to posterior capsule, even with opacities present. This test can be used to aid in exams for Glaucoma screening, Cataract surgery, and refractive surgery.





The Wavelight Topalyzer – Enhancing Contoura Vision

With this new Wavelight Topalyzer at Shady Grove Ophthalmology, Dr. Roberts patients benefit from a more personalized Wavelight topalyzerLASIK procedure. Contoura Vision is the latest refractive system from a leader in refractive eye surgery lasers “Alcon”.  The Wavelight EX500 Excimer Laser combined with the Topolyzer creates a unique and very personalized mapping treatment plan for every patient. Its speed and precision makes it the best available for Topography-guided LASIK treatments.

Modern Refraction

Shady Grove Ophthalmology uses “Intelligent technology” when examining patients. The use of high tech equipmentNidek Epic RT-5100 Refractor - Shady Grove Ophthalmology
allow us to precisely and accurately measure refractions. Some patients have significantly different prescription values between their day and night pupils. By a touch of a button it is possible to examine night-time visual acuity under low light conditions.


Auto Refraction

Auto Refractor ARK-530A - Shady Grove OphthalmologyOur office has automated refractors to ensure measurement for your prescription. An autorefractor is used to automatically determine a baseline of your prescription. An autorefractor, like a manual refraction, determines the lens power required to accurately focus light on your retina.

The auto refraction takes only a few seconds, and the results obtained from the automated test greatly reduce the time required for your eye doctor to perform a manual refraction and determine your eyeglass prescription. We use cutting edge technology to ensure your prescription is right every time!

Visual Field Testing

Visual Field Testing - Humphrey Field Analyzer

During a glaucoma eye exam Dr. Roberts may use a Humphrey Field Analyzer (HFA) to examine your eyes. Also known as a visual field test this type of eye exam is helpful in detecting if you have problems in central and peripheral vision which may possibly be caused by glaucoma, neurological deficits, strokes, or brain tumors. The machine will provide a detailed printout of the patient’s visual field.

ICARE Tonometer

ICARE Tonometer - Maryland Eye DoctorGlaucoma screening – This device the ICARE Tonometer requires no drops for patients and allows for a painless accurate measurement and has an important role in glaucoma screening. The ICARE tonometer is based on a proven accurate measuring principle, in which a very light probe is used to make momentary contact with the cornea. The measurement is barely noticed by the patient and often does not even cause corneal reflex. For ophthalmologists like Dr. Roberts this is good news, because the device not only makes IOP measuring a more pleasant experience on all patients, it is also an important break-through for succeeding with non-compliant patients (e.g. children and dementia patients).


For the Diagnosis and Management of Dry Eye Disease

TearLab is the single most accurate and objective test for diagnosing Dry Eye Disease. The TearLab system is used to measure the osmolarity of human tears to aid in the diagnosis of dry eye disease in patient suspected of having dry eye disease, in conjunction with other clinical evaluations. The test is fast, easy, and very accurate requiring only a very small amount of tear for analysis. It is not intrusive, and requires no anesthesia for the test to be performed.


The Osmolarity of your Tear film, determined by the TearLab Osmolarity system, is a measurement of the salt content in your tears. Osmolarity is the accepted gold standard for objectively diagnosing Dry Eye Disease. Essentially, osmolarity gives doctors a meaningful measure of the health and stability of the protective tear film that covers the surface of the eye.


Dr. Roberts will test both eyes, and take the highest result of the two eyes to determine your “Osmolarity Number.”Accredited Dry Eye Center
Once your “Osmolarity number” is generated by TearLab’s lab on a chip technology, Dr. Roberts can determine
whether you have Dry Eye Disease, and if so, whether you fall into the mild, moderate, or severe category. This will aid in the development of the appropriate treatment regimen to bring the ocular surface and tear film back to good health.
