NightLensR OrthoK Lenses
Approved for Overnight Wear
Simply put, Wave offers a higher level of orthokeratology design. No other orthoK lens offers Wave 's design platform feature set. Every eye is different and every lens should be as well, especially orthoK lenses. And they are approved for overnight wear.*
The first step is proper centration. Since Wave is utilizing the entire corneal surface map and not just K readings, our designs tend to be larger. This results in a more comfortable fit with better centration. Next, Wave duplicates (closely but not exactly) the corneal periphery into the periphery of the lens to further enhance centration.
The designer has the option of four peripheral/central lens design combinations: spherical/spherical, toric/spherical, toric/toric, free form (asymmetric)/spherical. To help you avoid any surprises, Wave defines the proximity of the molding transition zone to the pupil diameter, an important indicator of potential flare or glare.
All standard Wave controls are available to tune the fit to the designer's preferences. With Wave 's Custom Settings feature, the designer has the option of saving preferred settings for future design sessions.
Wave 's orthokeratology lenses are branded as NightLens®.

"Two sets of post wear topographies for this 9 y/o girl. Previously tried CRT and another company's 4-curve lens with less than stellar results as you can see in the (left) image. Right image is 1 week after dispensing Wave lenses." - Wave User

Orthokeratology with a Medmont Topographer
Typically I design most corneal Ortho K lenses in GSym and rarely in Freeform. Below is an excellent example of using Freeform for corneal design OK, the Rx is -2.25 -3.75 x 89 and as you can see, the cornea is highly asymmetric but I did need to resort to an oval treatment zone. The results far exceeded my expectations residual Rx is pl -0.75 x 90 but she is 20/20-2 uncorrected and a very happy camper. This was on the first lens. --- Thomas Weshefsky OD

"I thought I would share this LD mold case with everyone. I have a little girl (9 yo), with high myopia/astigm. I tried 6 different regular CM designs, with very little success. Centration was impossible, central islands, double ring, smiley patters, .. you name it, I had it all; did not know what to do anymore.
After attending Peter Wilcox et al lecture on LD corneal molds, I came back home and fitted a few of these hard to mold cases I followed the concept I was taught with a little twist, designed oval, ballast prism and dot at 6 for insertion reference.
They all got better or MUCH better, the one I am sharing is the one of them.
The results are attached, pt is now 20/25 (like she was on specs), mom and daughter are finally happy and the school nurse wants to have us give a talk to parents at school. Everybody is happy."

Q. Has anyone had success with molding a low myope (-0.50) into a higher myope using hyperopic molding techniques in order to establish better near VA and compensate for presbyopia in a 60 y.o.
A. Attached is a design for my eye, un-molded –1.00-0.50 x095, I am 58, so need a little more help at near. My target near power is –1.75 but I wanted to minimize the distance blur. I input my rx power as +0.75, (taking me from a –1.00 to a –1.75 post mold centrally but less minus toward the peripheral). I used a thick lens, .30 center and a little loose superior and inferior to decenter the lens molding inferior thus putting the near add a little lower while still trying to get the best distance vision centrally. The lens is very comfortable. I am pleased with the vision. 20/25 distance, 20/20 near for this non dominate OS. My OD dominate I use a traditional ortho-K correction for distance.

Low E OrthoK
Case J, S - OrthoKeratology with VERY FLAT Ks, VERY LOW eccentricity
This case probably WOULD be impossible with one of the non-custom ortho-k lens brands out there. I wasn't certain that it could be done even with Wave , but I knew that the only shot I had would be to design in AXIAL mode
One of the takeaways I got from this case was that when a patient tells us that their VA starts out great in the first half of the day but wears off quickly, even after weeks of wear when the VA should be stable all day....or they complain that some days the VA is really good but other days it's really bad, the likely reason is not enough TD for that patient's combination of their amount of refractive error, degree of corneal flatness, and low eccentricity. My staff was totally convinced that this kid wasn't wearing his lenses every night (as he said he was), and I must say that I certainly had the same thought a number of times.
Jim Edwards, your Wave program never ceases to surprise and challenge and delight me!
