ORange is the first intraoperative wavefront aberrometer used in cataract surgery. It is comprised of an optical head that is attached directly to the surgical microscope and connected to the ORange processor and touch-screen monitor. ORange is used during cataract surgery to accurately measure the refractive value of the eye. At any point during surgery the surgeon captures a wavefront of the patient’s eye. The ORange processor then analyzes the captured data to calculate the refractive value of the eye.

ORange is unique in its ability to measure the optical aberrations in the eye during a surgical procedure such as cataract surgery. Prior to this new technology, ophthalmic surgeons were unable to assess the quality of vision during cataract surgery, and would often wait until days after the surgery to determine the optical accuracy of the surgical results.


ORange works by directing a beam of low intensity laser light into the eye during the surgical procedure. The laser light reflects off of the patient’s retina, and sensors in the ORange instrument analyze the reflected wave of light exiting the eye. This real-time analysis measures all of the eye’s unique optical characteristics, and gives the surgeon an accurate measurement of the eye’s focusing capabilities.

Using this revolutionary technology, Dr. Benjamin can evaluate the optical conditions in the eye throughout the surgical procedure and make surgical decisions at the precise moment that can best affect visual outcomes. The measurement occurs when and where it matters most – during the surgical procedure, not afterwards. ORange can assist Dr. Benjamin in more accurately determining factors such as astigmatism correction and intraocular lens implant accuracy.

The end result is more precise surgical outcomes. This new technology can help doctors and patients achieve better results, and most importantly, an improved quality of vision.

Why We Use the Orange System

During preparation for cataract surgery, Dr. Benjamin uses measurements acquired at the office to calculate the power of the lens implant that will replace the cloudy cataract. For patients who chose to address corneal astigmatism at the time of cataract care,  this surgical planning  includes calculations for correcting the astigmatism.  Even with the use of the most accurate measuring devices such as the IOL Master, and the Oculus Pentacam, the result of even the most advanced formulas is always a best possible guess.

ORange technology allows Dr. Benjamin to measure the refractive imperfections of the eye in real time during cataract surgery.  This gives Dr. Benjamin ability to make adjustments in the power of the needed lens, and the amount of astigmatism correction at the time of surgery.  Because the results of the required manipulations are evident immediately, there is much reduced need for the patient to undergo subsequent laser or other corrective procedures.    To the patient this means that there is much less likelihood that there will be what is termed a refractive surprise after the surgery. 

At the Benjamin Eye Institute we are so confident of the results produced by the ORange that for those who elect the use of this technology, we guarantee the refractive result and back it up with our own in office Allegretto EyeQ 400 EXCIMER laser vision correction platform.  In plain English this means that if you choose ORange and there is residual nearsightedness, farsightedness or astigmatism, we will perform laser vision correction to eliminate it.  Free of charge!
