Advanced Corneal Engineering Inc. was founded by Dr. Roger Tabb. He has been heavily involved in the design of all types of contact lenses including Orthokeratology lenses since 1964. The Nightwear End Result Orthokeratology lenses have been in the works since about 1968 but no lathe equipment was capable at that time to manufacture these designs.

Dr. Tabb produced lens designs for keratoconus, corneal rehabilitation of refractive surgeries, myopia control, bifocals designs, and many combination designs as well as soft lens designs. He is an independent practitioner, contact lens designer and consultant for various contact lens specialists, laboratories and corporations nationally and internationally. He is also a patent holder and has patents in progress at this time.

Dr. Tabb coined the term “corneal rehabilitation” and invented a process for that purpose with contact lenses in 1964 while working for a doctor in Fort Collins, Colorado. Dr. Tabb is a recognized international authority in the contact lens field in many areas such as keratoconus, orthokeratology, bifocals, post corneal surgery rehabilitation, and soft lens designs.

Orthokeratology, like any technology, started with an observation, a curiosity, speculation, clinical data, comparison of information, scientific scrutiny, and was succeeded by 40 years of hard work.

The old types of orthokeratology had their beginnings with Dr. George Jesson when in 1957, he reported at one of the 1st NERF meetings in Chicago, on UCVA [ uncorrected visual acuity ] improvement with wear of contact lenses. While the Jesson method at that time was to fit 2.5 diopters flatter than K, it did provide a platform for others to continue investigate and progress.

Dr.s’ Charles May and Stuart Grant used a method of 0.50 diopters flatter than K and changed the lens when the K flattened 0.50 diopters. In 1980 a California Optometrist, Dr. Joseph Lilly, listed 8 top methods of the time. The Tabb-Hydraulic method was the only one listed that was not mechanical but hydraulic in nature. The degree of control of this Tabb hydraulic method was exceptional but had a limitation of the amount of power it could change of about 2.50 diopters.

Dr. Roger Kame coined the term “Reverse Geometry” describing what was considered the newer generation of orhtokeratology lenses. There were a few of these designs around for years before they got recognition in 1989 and since that time the major players have been working hard to bring them to the forefront. A few of these players are Wlodyga, Stoyan, Blackburn, Reim, Montford, Day, Rinehart and Tabb. In the last few years many more have entered the area of Orthokeratology across the planet. In fact there are some organizations that never allowed Orthokeratology papers to be discussed at their meetings until 1996. Orthokeratology is becoming known the world over. Now two of largest button manufacturers have decided to join in the efforts as well. It may be that they believe Nightwear End Result Orthokeratology may the salvation of the Gas Permeable contact lens industry.

So where are we now? NightWear End Result Orthokeratology [N.E.R.O.] lenses have completed the patent process and Daytime wear Orthokeratology lenses have been approved by the FDA in 1999 by Contex. In 2002, a Nightwear Orthokeratology lens passed the FDA called the CRT [Corneal Refractive Therapy]. This will help pave the way for more of the NERO [Nightwear End Result Orthokeratology] lenses to be approved. Currently, Dr. Tabb received his patent on the NightMove™ and Emerald™ technology and is completing the FDA process. In 1997 there were no Orthokeratology lenses which had been put through the FDA process. Since there was little scientific research available, the FDA needed a yard stick to go by. Dr. Tabb put a study together that was carried out by two exceptional students, Robert and Abby McNeil, for their doctorate thesis at Pacific University in 1998. The study was done within the scientific rigors and was deemed the study that brought orthokeratology out of the dark ages. The results were exceptional on 26 subjects and most of those subjects still wear their lenses. All of the these lenses were modified to TAIL [ Tabb Acuity Improvement Lens]standards. The FDA study for the Emerald design [patent held by Tabb], was thus started in September 1998 at Euclid Systems Laboratories.

What does this mean to you? Now you have the ability to correct a greater range of complex eye conditions without surgery or other invasive procedures, thus bringing more benefit to your patients. At the same time you have access to a pioneer in the field of Orthokeratology, Dr. Tabb, who can answer your specific questions regarding fit, function, and modification on a consultation basis.

Our Benefits
So why should we care about orthokeratology now?
• It is non-invasive and, in our opinion, much safer than any of the refractive surgeries.
• It is as fast as the surgeries for up to -4.00 with -1.50 diopters of cylinder.
• It requires no healing that needs to take place since nothing is damaged.
• It is very accurate.
• It is a no-brainer for the patient. i.e. always chose the least invasive therapy first.
• It is a welcome and excellent option for the patient in addition to the surgeries.
• It is reversible and very flexible.
• If someone who has had NightMove™ orthokeratology wants to have the final power changed from the result obtained they received it can be done with a lens change.
• If a patient wants to see with one eye near and the other distance they can. It can be changed from one eye to the other by simply changing lenses.
• If this same patient wants to see at distance once a week with both eye but near with one eye the rest of the time, it can be done easily.
• If the patient wants to go back to their original prescription they can.
• If the patient has ghosting, adjustments can be made to improve the condition by changing the lenses in most cases.
• NightMove™ orthokeratology can be managed and maintained even as an individuals eyes and eye need change over the years.

Introduction To The Team
Bio Sketch for Roger L. Tabb, O.D., F.A.A.O., I.S.C.L.S.
Dr. Roger Tabb is a resident of Wilsonville, Oregon with an optometric practice in addtion to a consulting and engineering firm in Beaverton, Oregon [ the postal address is Portland but is actually in the city of Beaverton] since 1969 and serving in the same location since 1978.

Dr. Tabb initiated his formal education in 1959 at Colorado State University in Engineering. He received his B.S. and O.D. degree from Pacific University College of Optometry in 1966. He is an optometric practitioner, contact lens designer, consultant, and perceptual therapist. He is founder of the Beaverton Optometric Group, P.C. and founder and president of Advanced Corneal Engineering, Inc. an Oregon Corporation in consulting. Dr. Tabb invented the theory and initial formulation for the Hydraulic contact lens designs, SightMove™ Series Nightwear End Result Orthokeratology lens designs, Hydraulic Keratoconus lens designs, Hydraulic corneal rehabilitation via contact lens designs for refractive surgeries, and bifocals designs. In 1964 Dr. Tabb developed techniques and language for modification of rigid lens materials in office to improve the success rate of fitting. He also developed a method for changing power on the contact lenses and resurfacing to alleviate scratches and renew the surface of a contact lens for continued wear.

Dr. Tabb holds the patent on the RAU [ Residual Astigmatic Umbrella ]contact lens design patented in 1974. He also has patents on the RAU bifocal and the SightMove™ Refractive Lens™ series which includes the well known Nightwear End Result Orthokeratology [NERO] lenses such as NightMove™, AstigMove™, LightMove™, HyperMove™ , and others. Dr. Tabb is inventor of the Emerald™ series that is used and presently manufactured by Euclid Laboratories. Mr. Randy DeWoolfson aided in the Emerald™ design with his mathematical skills. Dr. Tabb is an independent consultant for various contact lens specialists, laboratories and corporations nationally and internationally.

Dr. Tabb has designed and taught contact lens and orthokeratology courses from basic to masters level for the past 30+ years. He has lectured nationally and internationally for 30+ years, in all phases of contact lens fitting, modification, lens design, physiodynamics, and perception. He has written a book in the perceptual field which is in process of being published. He has published numerous papers on Perception, Contact lenses, Orthokeratology, Keratoconus, and other related topics.
