The SightMove Refractive Lens Series™ is a series of contact lens designs to effectively and accurately perform various types of sight and physical changes for control of corneas in a therapeutic sense. They were designed by an optometric physician, fitter, consultant, teacher, engineer, & humanitarian. The primary goal of this designer has always been to produce the best technology in order to make doctors the champions of their patients. This complete lens series does just that. The SightMove Refractive Series™ consists of the following lenses systems.

LightMove™ - An Orthokeratology lens designed primarily for Daytime Wear Orthokeratology and has a reverse geometry structure This lens can also be used for regular RGP wear and is very comfortable and effective while affording normal or improved uncorrected visual acuity for hours at a time after the lens is removed. This lens should be considered for higher myopes that may not get a satisfactory result with a Nightwear End Result Orthokeratology type lens { NERO}. Unlike the NightMove®, the LightMove™ is designed to conform to Daytime Wear conditions.

NightMove™ - This lens is designed specifically for Nightwear End Result Orthokeratology { NERO}. NERO lenses are the most well known world wide and have literally reversed the thinking of professionals the world over regarding safety, efficacy, and value as a tool to provide, for patients, functional waking hour uncorrected visual acuity. The NightMove® technology and others like it, have eliminated the need to fear the damage that refractive surgeries have proven to have the capability to produce. To date, there are no known permanent ill side effects created by NightMove® Orthokeratology lenses. These lenses have been in use at the Beaverton Optometric Group since the early 1990’s. To our knowledge, no other lens similar to this one was produced until 1996. The precursor to the NightMove™ [ then labeled TAIL™ for Tabb Acuity Improvement Lens ] was a 12 lens series and was derived from earlier mathematics. A cousin of the NightMove® is the Emerald™, first produced in 1999 by Euclid Systems, Inc. under Dr.Tabb’s patent.

The NightMove® lens has been compared to many of the other major brands and continues to maintain well above a 90% success rate for powers up to –5.00 as tested clinically in many clinics across the country and abroad. The NightMove® lens is protected by US Patent No. 6,582,077 issued June 24, 2003 to Roger L. Tabb. The other SighMove™ Refractive Lens™ Orthokeratology lenses are protected by this same patent via the use of the same technology but manipulation and adjustment of the various curves and calculations to create a different end result for the satisfaction of the patient and the fitting doctor.

AstigMove™ - The AstigMove™,is from the same technological arm of the NightMove™ and is a NERO type lens. It is altered in calculation to take into account the differential of the astigmatic curves and allow even change of the two curves differentially. The success of this lens has been impressive, but it is important to recognize that there are still more obstacles to overcome with certain types of astigmatism. There is no other known astigmatically calculated lens to our knowledge that is available. This lens has corrected up to –4.00 diopters of astigmatism. More characteristic would be cylinder powers less than –2.50. Certain types of astigmatism are more difficult to control such as against the rule astimia [ ie vertical axis from 60degrees to 120 degrees. One half to three quarters of the astigmatism is generally the amount that is treatable.

HyperMove™ - The HyperMove™ technology has been developed distinctly by Dr. Tabb and to our knowledge no other lens has been designed for hyperopia with this specific calculation thought process. Just recently, we were made aware that there is a lens being developed in Australia for hyperopia but it will only handle up to +2.00. The first HyperMove™ fitted was in 1995. There are few doctors who are even aware that hyperopic orthokeratology exist, but we are sure they will become aware very rapidly. The ranges of power have been from +3.50 down to +.50. Most of the patients have been successful and in fact they even find that they are able to function without their reading glasses as presbyopes. This technology is pointing to a huge untapped market. There are likely more hyperopes in the US than myopes. The market is enormous and should be a great one to tap with non- surgical methods of refractive change that give lasting daytime vision.

SuReHaMove™ [ for Surgical Rehabilitation ] - This lens technology has a rapidly growing market and in the future could potentially be enormous world wide. With the past 20 years of Radial Keratotomy refractive surgery problems and the burgeoning growth of LASIK there will be more and more patients who will need our help in restoring impaired vision, comfort and perception as a result of refractive surgical damage. The only method of restoration without further surgery is with intelligently designed gas permeable contact lenses. The SuReHaMove™ fits that description perfectly. It enjoys use of the same computer design program as one of the 5 NightMove™ methods of calculation with adjustments in how the parameters are arrived at. These designs have proven to be extremely effective and Surgical centers are now beginning to see the results of how well these lenses perform. Patients many times are ecstatic with these lenses because they are not able to see well with glasses, softlenses, or spherical base curve GP lenses but achieve excellent acuity again with the SuReHaMove™. The design is a reverse geometry system with a large optic zone and cannot be safely calculated with an elevation calculation. There are a series of design changes that become necessary for surgical rehabilitation. These are all looked to in the designing of a SuReHaMove™ system.

ConeMove™ - The technology for this design was developed from the Tabb-cone-hydraulic design originated by the author in 1970. It was combined with the reverse geometry undercarriage for movement and centering control in the late 80’s. The theoretical construct was to create a hydraulic performance under the lens so the pressures under the lens were equally distributed across the surface of the lens and cornea. This worked very well for most cone configurations even with the highly irregular topographies of some of these corneas. The ConeMove™ has this concept in mind but with added mechanical pressure with the stabilization of lens movement by the controlled hydraulics under the contact lens surface. This lens works very well for nipple cone conditions as well as pellucid marginal degeneration. It is calculated with precision in mind for corneal control. In a few cases these lenses can be used in a NightMove™ fashion and orthokeratology can be produced with good and safe lasting visual acuity effects all day. This lens has been very successful for full time Daytime wear..

NoMove™ - The purpose of the NoMove™ lens design is to keep the corneal shape as stable as possible so that little to no change takes place with daytime wear of contact lenses while affording premium aided visual acuity. Pilots, firemen, police officers, athletes and business people who may work long hours many times prefer to be able to take their contact lenses off and put their glasses on and see clearly immediately so they can continue to work. These people don’t want to risk the surgeries, may be too high in prescription for surgery or Orthokeratology but still need and want exceptional VA and comfort. This lens takes care of that need. In addition, a very positive side effect is that this lens causes an increase in comfort as reported by patients, even over their old soft lenses at times. The probable reason for this is that it moves about 2/3 less than a normal spherical RGP design. In addition, it allows less debris under the surface around the periphery because of a natural seal congruent with the design, so tends to maintain great comfort longer even when the tear volume drops off at the end of the day. It is a great first lens of choice for any and all full time day wear RGP fits. The corrected acuity is excellent, surpassing other RGP designs, soft lenses, and glasses. Other lens designs by Advanced Corneal Engineering for complete contact lens practice control and quality patient care are which are not in the SightMove™ Refractive Lens Series™ are:

T-Hydraulic™ The Tabb – Hydraulic fitting system was developed in 1964 in Fort Collins, Colorado at Dr. Robert Biggs office. Dr. Tabb was working there and while fitting problem patients, developed this concept of fitting along with using this design for corneal rehabilitation. The T-Hydraulic™ is designed with apical clearance for hydraulic control and paracentral asphericity for physiology and comfort control. This design has been a work horse and has been fitted on literally thousands of patients over the years. The T-Hydraulic system creates a hydraulic containment system under the lens via apical clearance and para-central curves designed as control curves for tear metering exchange, centering, lens excursion containment and bearing control for comfort. The peripheral curve at the extreme periphery is to provide a tear reservoir to hold tears in reserve for exchange under the lens to refresh the system on the blink. This is still a work horse across the country and in the world. Even though this lens was introduced in 1970, it was little known until lately. It is rapidly becoming much more popular than the old flat fitting philosophies of 40 years ago.

The concepts regulating the T-Hydraulic™ design lent itself to the T-hydraulic Orthokeratology design used in the Lynn Coon, Pacific University study, published in the AOA journal, 1980 and 1981. Dr. Coon did a landmark study and it was a 5 year longitudinal study that proved Orthokeratology with the T-Hydraulic™ method was safe and effective for low powers and comfortable. Some of the mathematics in this concept were the stimulation for other designs for keratoconus, orthokeratology, and corneal rehabilitation.

NoMoBifocal™ – This lens is an interesting combination of a lens design patented by Tabb in 1974. It was basically a large improvement over the “Panafocal” concept. It was called the Residual Astigmatic Umbrella™ lens. It was manufactured and distributed by Precision Cosmet and a handful of other laboratories. To stretch this into a bifocal was a natural and, it was and is, the most successful bifocal used at Beaverton Optometric Group. Many patients were fitted and well above 85% of the patients were very successful. Some of them still wear this lens after 10 , 30 years of wear. Combined with the RAU front surface technology, the NoMove™ technology is used on the back surface for control of movement, centering, comfort. This expanded efficiency of the bifocal-optical system for maximum acuity at all distances. The success rate has been high for this lens. It is a controlled, simultaneous bifocal. It is extremely versatile and can be modified in many ways to achieve peak performance.

T-Cone-Hydraulic™ – This design is similar to the T-Hydraulic(tm) with changes in the design to encompass the added variables in keratoconus. The first apical clearance design of this nature for keratoconus was designed by the author was 1970. It is safe to say that there are a few thousand keratoconic patients wearing this design and have for 10-30 years with great success. T-Hydraulic system is an apical clearance system controlled by the pericentral curve, which the author called the control curve [it could be design steeper or flatter than the cornea it rested on creating hydraulic control] followed by a 12mm radius peripheral curve, which the author calls a tear reservoir curve. This technology was used extensively and resolved many problems encountered with the old flat K and on K fitting methods.

T-Cone-Compression™ – A Reverse geometry design and works well for pellucid marginal degeneration as well as some nipple cones.

T-Compression™ – Reverse geometry design for daytime wear which is a three curve lens. First one made by the author was 1975 and reported on at Bronstien laboratories annual contact lens seminar. Because of difficulty manufacturing the reverse curve, this lens was not used much until 1989 when Stoyan manufactured and Wlodyga published an article about accelerated orthokeratology. Tabb did not go after a patent on this design but Stoyan did and received it in 1989 called an OK-3. The T-compression is similar in structure but the parameters are controlled by the fitting doctor.

T-SL bifocal™ – Translating bifocal with prism ballast and total control for the doctor. –T-SL bifocal™ is a spherical back surface with an aspheric periphery and partially manufactured by the doctor if desired. A lens is ordered that has the full reading power in the lens with the prism ballast. The lens is fitted for comfort and vision at near. Then the orientation is noted with a dot at the prism edge of the lens, and with the orientation, and over-refraction for distance, the power is added for the distance portion. This is most successful translating type bifocal we have observed. This does require that the doctor be capable of adding power to the lens or send it back to the lab and have them put it on.

RAU LENS [ RAU = Residual Astigmatic Umbrella ] - A patented lens design for the resolution of low to moderate residual astigmia with GP lenses. Range of operation is -0.25 to –2.50 cylinder, any axis. The RAU lens was developed in 1972 and patented by Dr. Tabb in 1974. The purpose of this design is to alleviate the problems of low to moderate residual astigmia in rigid lens fitting without the use of prism ballast. Advantages are that the fitter can use their usual fitting method that they are comfortable with as long as reasonable centering occurs.

RAU BIFOCAL - is a natural extension of the RAU design. The original bifocal has resolved up to +2.50 [ full adds ]. Centration is important. Now, a combination can be used for this bifocal. The RAU is placed on top of a NoMove™ back surface technology. This gives a nearly perfectly centered lens in nearly all cases. These lenses are capable of keeping the optic zone over the pupil. This creates excellent function for the bifocal which is a simultaneous type. The speed at which most individuals adapt to this lens is rapid compared with most others that have been used and tried at the BOG clinic.
The bifocal is calculated differently than the RAU lens. The RAU is calculated for the balancing of light for residual astigmatism. The RAU bifocal is calculated to produce a specific add for the patient that will be functional for near viewing.
