EchoRule PRO

Visionary Solutions

TRUSTED COMPANION FOR

YOUR CATARACT PRACTICE

The EchoRule is a widely used & popular equipment amongst the Indian Ophthalmologists. Since the mid-nineties of the last century the EchoRule has assisted in millions of IOL calculations for Indian cataract patients. The EchoRule has undergone several improvements such as better acquisition and processing methods, faster microprocessors, more features, newer formulae.

The EchoRule followed by Echorule2 and then the EchoRule Proare well established for accuracy and simplicity of operations.

The modern Ophthalmic Practice employs both Ultrasound and Optical Biometry. The ophthalmologist must keep ultrasound biometry as the primary instrument or keep it on hand for patients who cannot be measured with optical biometry. Both technologies are needed in the modern Cataract & Refractive surgery practice. Considering that India’s share of the Cataract & IOL surgeries is over 20% of the Global 35 Million cataract surgeries, the EchoRule plays a significant role.

Surgeons have relied on the applanation technique of the Ultrasound for years, and most have personalized their IOL constants to try to counteract the possibility of the corneal compression error. However, no one disputes that immersion ultrasound is the gold standard of biometry. (In fact, in the earlier days the Optical Biometers, which have also proven to be extremely accurate, was calibrated to immersion ultrasound.

HIGH SPEED

MEASUREMENT

The EchoRule gives you the fastest acquisition of the anatomical measurements of the Eye, including the Axial Length. The ten rapid measurements help you to evaluate the correct Axial Length & navigate through artifacts & glitches with the help of the Standard Deviation values.

Totally dependable and no surprises.

ERGONOMICS & EFFICIENCY

The EchoRule is compact and portable. The LCD touch Screen with its intuitively designed user interface makes the operations, simple & quick. The printer is built in but also provides for a more elaborate printout using an external printer using the USB port.

IMMERSION BIOMETRY

Today, patients expect cataract surgery to not only restore visual clarity, but to provide excellent vision in refractive terms as well. Unfortunately, the commonly used method of contact biometry isn't accurate enough to produce outcomes that live up to these expectations. The only way biometry technicians can obtain consistent, accurate, reliable readings is by eliminating the error induced by corneal compression.

Immersion Biometry also assists you to accurately measure Lens Thickness & Anterior Chamber Depth, which is required for current Fourth Generation Formulas.

Immersion ultrasound truly is the gold standard in biometry. It provides the efficiency and accuracy you need to achieve the standardized, high-quality postoperative results that today's cataract surgeons and patient demand. Making the switch is easier than you think, and doing so will help you provide your patients with the level of care they deserve.

A common misconception is that immersion biometry is more difficult to perform and more time-consuming for the technician.As a matter of fact, the opposite is true. Immersion biometry is easier than the contact method, and it takes a fraction of the time to perform. This means that a technician using immersion biometry is not only more accurate but also more efficient.The immersion technique is quite simple. The technician gently places a small scleral shell on the anesthetized limbus of the Eye & the probe is either hand-held within the fluid or locked into position in an infusion shell.

The Following image indicates the display that you will see on the EchoRule Pro when measuring with an immersion shell & performing immersion Biometry.

Infusion shells are designed to fit specific probe diameters and sizes,so be sure to buy the BioMedix immersion shell, when ordering the equipment.

The EchoRule Pro meets the challenges of the modern-day Cataract & Refractive surgeries for enhanced visual outcomes of your patients. It is the single most effective solution for measuring and calculating all of your patients and refining your surgical outcomes. It has the ability to measure 100% of patients and works great with dense cataracts or patients with fixation difficulties.

THE IMMERSION SHELL

According to Jack T. Holladay, M.D., the best method is probably to measure the first 20 or 30 patients using both the contact and immersion techniques. Once you find the average difference between the two measurements, simply double the number and increase your constant by that amount. For example, if the average difference in length between the contact and immersion methods is 0.2 mm, add 0.4 to the constant.

GUARANTEED TOTAL ACCURACY

MAKING THE SWITCH TO IMMERSION BIOMETRY

Be sure to seat the patient on a comfortable reclining examination chair. The patients head will be tilted looking up. A towel on the shoulder of the patient to catch the leak of the fluids from the immersion shell will help.

The probe is placed perpendicular in the shell and patient fixated on the LED. Measurement is instantaneous.

EchoRule Pro can help you in doing high quality immersion biometry.

The Display screen must show tall, straight spikes of equal height, with good resolution of the corneal peaks and retinal and scleral spikes. Units that can't display straight spikes or haven't properly compensated for sound attenuation make perpendicular errors much more difficult to detect. They also make it impossible to be sure of visual axis alignment.

It is important that the four gates, or callipers, are visible --and moveable -- in both automatic and manual modes. You should be able to verify exact measuring points for the anterior chamber depth, lens thickness, and vitreous chamber length, and be able to move the callipers when they're incorrectly placed. (Though rare It is possible that EchoRule may occasionally place a gate at the wrong measuring point -- for example, when a dense cataract causes multiple spikes between the anterior and posterior lens echoes.)

Look for each section of the eye (anterior chamber depth, lens thickness, and vitreous cavity) at its individual sound velocity, and then add them together for the total eye length measurement. Application of the correct velocities that compensates for the media it travels from the cornea to the retina will produce the most accurate results.

Make sure you can adjust the gain setting. Cataract density varies, and the amount of gain you need will change accordingly.

You can contact any one of the BioMedix Sales offices situated all over India & ask them for a Demo and trial unit with scleral shell, so you can use the immersion technique during the trial period.

Make sure you and your biometry staff read the equipment manual thoroughly.
