About A.C.E. and Orthokeratology

Orthokeratology (also referred to as Ortho-KOvernight Vision Correction), refers to the creation of gas permeable contact lenses that temporarily reshape the cornea to reduce refractive errors such as myopiahyperopia and astigmatismThis method can be used as an alternative to eyeglassesrefractive surgery, or for those who prefer not to wear contact lenses during the day.

Advanced Corneal Engineering Inc. was founded by Dr. Roger Tabb (O.D., F.A.A.O., and I.S.C.L.S.) in 1964.

Dr. Tabb is a recognized international authority in the contact lens field in areas such as keratoconus, orthokeratology, bifocals, post corneal surgery rehabilitation, and soft lens design.

He pioneered techniques for modification of rigid lens materials to improve the success rate of fitting. Additionally, he developed methods for changing power on the lens and resurfacing to renew the lens performance.

THE SIGHTMOVE REFRACTIVE LENS SERIES

Designs to effectively and accurately perform various types of sight and physical changes for control of corneas in a therapeutic sense. The entire series was created by optometric physician and engineer Roger Tabb to be a safe, non-surgical solution to vision problems. The SightMove Refractive Series™ consists of the following lenses systems.

LightMove.png

LightMove©™
An Orthokeratology lens designed primarily for daytime wear.  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).

NightMove.png

NightMove©™
This lens is designed specifically for Nightwear End Result Orthokeratology (NERO). NERO lenses are the most well known world wide for their safety, efficacy, and value as a tool to provide functional waking hour uncorrected visual acuity. The NightMove® continues to maintain well above a 90% success rate for powers up to –5.00 as tested clinically across the country and abroad.

Astigmove.png

AstigMove©™
From the same technological arm of the NightMove™, AstigMove is altered in calculation to take into account the differential of the astigmatic curves and allow even change of the two curves differentially. This lens has corrected up to –4.00 diopters of astigmatism.

 


Conemove.png

ConeMove©™
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. 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. ConeMove has proven 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. In addition, it allows less debris under the surface around the periphery because of a natural seal congruent with the design, allowing for greater comfort longer even when the tear volume drops off. 

HyperMove©
This was the first lens designed for hyperopia with this specific calculation process. The ranges of power have been from +3.50 down to +.50. Most of the patients are able to function without their reading glasses as presbyopes.

These lens designs have been copyrighted and trademarked in perpetuity under common law and natural law.

OTHER LENS TYPES

T-Hydraulic©™
The T-Hydraulic™ is designed with apical clearance for hydraulic control and paracentral asphericity for physiology and comfort control. The peripheral curve at the extreme periphery produces a reserve tear reservoir under the lens to refresh the system on the blink. Originally introduced in 1970, the T-Hydraulic is rapidly becoming much more popular than flat fitting philosophies.


NoMoBifocal©™
Manufactured and distributed by Precision Cosmet and a handful of other laboratories, the NoMoBifocal is extremely versatile and can be modified in many ways to achieve peak performance.  Combined with the RAU front surface technology, the NoMove™ technology is used on the back surface for control of movement, centering and comfort. 85% of patients reported success and many continue wearing this lens for long-term usage.

 

T-Cone-Hydraulic©™
Similar to the T-Hydraulic(tm) with changes in the design to encompass the added variables in keratoconus. T-Cone-Hydraulic is an apical clearance system controlled by the pericentral curve, followed by a 12mm radius peripheral 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. The T-compression is similar in structure but the parameters are controlled by the fitting doctor.

 

T-SL Bifocal©™ 
A translating bifocal with prism ballast and total control for the doctor.   The T-SL bifocal™ is a spherical back surface with an aspheric periphery. A lens is ordered that has the full reading power 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. T-SL Bifocal is most successful translating type bifocal we have observed.

 

RAU LENS©™ (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 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©™
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. These lenses are capable of keeping the optic zone over the pupil. The RAU bifocal is calculated to produce a specific add for the patient that will be functional for near viewing.
