ORLANDO, FL, November 03, 2013 /24-7PressRelease/ -- Over recent years, the practice of optometry and ophthalmology has taken enormous strides, especially in the area of technology and techniques used to achieve the most precise results during eye exams. The industry standard for reliable refraction is the phoropter, which has remained largely unchanged in over 80 years. With the phoropter, practices are required to have a minimum 16 feet refraction lane. With the introduction of a mirrored system, practices were able to use a 10 feet room to cut the lane in half. However, these slightly smaller room requirements still make it hard for practices in high-rent cities or practices with a high volume but smaller office space.
The PSF Integra
This latest innovation from Vmax Vision is touted as the complete Refraction-Lane-in-a-Box because it eliminates the need for a 16-foot refraction lane. Using cutting edge technology, the Integra offers 20 feet of effective refraction distance, cutting the needed space in exam rooms by two thirds. Moreover, it does this without sacrificing the highest level of precision and visual acuity.
Like its predecessor, the PSF Refractor , the PSF Integra uses Point Spread Function technology, which calculates a patient's subjective visual response. This neutralizes the perpetuation of higher-order aberrations, producing refractions that measure to 0.05D, and are as much as five times more precise than those obtained while using a standard phoropter. It may be the most significant advancement in technology since the introduction of digital technology to the projection process.
Accommodative Response Reduction
During the examination process, when using different devices that require a patient to look into a display box, an image is projected that simulates the required 20 feet of distance. The fact that projected image is only a few inches away from the patient and is perceived to remain inside the box produces what is called an accommodative response, in which the eye tries to reconcile the perceived inconsistency.
The simulated distance of the image is known as instrument myopia, and is thought to be the direct cause of such accommodative responses. Using the technology developed by Vmax Vision , the Integra creates an actual distance of 20 feet as perceived by the patient. This reduces or eliminates accommodative response created by the simulated distance used in other mechanisms.
Prior to this advance, remotely manipulated chart projectors were commonly used to perform exams. While this was a significant improvement over manually manipulated charts projected onto a wall screen. The PSF Integra also offers voice-guided instruction software, designed to guide the patient through each successive refraction test. This allows the doctor to save time and effort, while ensuring that each patient is adequately and correctly instructed.
Another ancillary improvement that is included with this system is Encepsion digital free-form lenses. Available as both single single-vision and progressive lenses, that are precisely designed to incorporate each patient's lifestyle and individual fitting data. They are manufactured to the highest standards, using 100 percent digital free-form Diamond Point technology and are double inspected to 0.01D of the PSF Integra's more precise prescription.
Beyond measurably improving the quality and precision of examination techniques, the PSF Integra offers other benefits to optometrists and ophthalmologists. Because it eliminates the need for such a lengthy refraction lane, doctors can now reduce the required space for each examination room. Exams can now be conducted in the pre-test area, so that all testing can be efficiently completed. This completely eliminates the need for a separate examination space. Concomitantly, they can afford to expand the number of exam rooms without acquiring additional office space. This will allow them to expand their practice and service offerings affordably. The benefits posed by this revolutionary system are ample. The efficiency and precision of the PSF Integra system will reduce errors, exam time, and help to ensure patient satisfaction.
Vmax Vision is pioneering solutions for eye care practices, introducing new technologies that bring greater accuracy and efficiency to the eye exam process and exceptional vision to eyeglass wearers.
With the PSF RefractorTM, patients can experience a less stressful eye exam while simultaneously garnering a more precise prescription. When the PSF Refractor's prescription is combined with Vmax Vision's premium line of Encepsion Lenses, patients can expect to achieve the Best Possible VisionTM.
