Ever gotten something with a name that’s way cooler than what it actually does? Well that’s not the case here. Our SLAMPAK has a cool name but what it does is even cooler!

We created our SLAMPAK (Single Lens Attached by Magnets Peli Assessment Kit) as an all-in-one solution for you to quickly demonstrate the Peli Lens to your patients and determine if they can benefit from it. What could be cooler than helping people who’ve lost some of their vision expand their visual field? We can’t think of anything. Except maybe a self-driving car. Or a Mars colony. But we digress…

What's the SLAMPAK?

We’ve been working with doctors and therapists for over 20 years to help patients with homonymous hemianopia regain as much visual field as possible (while improving their qualify of life).

The Peli Lens has been proven time and again to be the best solution for  helping homonymous hemianopia patients expand their peripheral vision (don’t take our word for it – check out the Peli Lens publications page if you want some super in-depth, scientific reading material).

But, we discovered that demonstrating the Peli Lens in-office can be cumbersome.

Why? Because the Peli Lens comes in two lens types and patients are afflicted in either their left or right eye. Up until now, that has required  keeping multiple pairs of glasses or fitovers on hand to use in the demonstrating process.

The other option has been to attach temporary Peli Lens prisms to the patient’s glasses to try them out. The drawback to this approach is that patients do not get the benefit of switching between their normal corrected vision and the temporary Peli Lens multiple times. Once the temporary lenses are attached to the patient’s glasses, that’s it. And, temporary prisms about 50% weaker than the permanent Peli Lens.

Enter the SLAMPAK.

Our SLAMPAK is a compact way for your patients to quickly and easily take the Peli Lens for a test run. In addition to being super easy to use, the SLAMPAK lets you demonstrate the full-powered Peli Lens in a removable format.

Here’s what’s included:

  • Fitover frame: using 3 magnets embedded into each side of the fitover frame, you can attach either lens to test oblique and horizontal prisms on the right or left eye without requiring your patients to take off their glasses (it also works for patients who don’t wear prescription glasses)
  • Oblique Lens: the oblique lens is suited for patients who need field expansion for driving or mobility
  • Horizontal Lens: the horizontal lens is best suited for patients who want improved mobility
  • Temporary Peli Lens Kit: our temporary Peli Lens kit lets you practice fitting and training patients for the temporary lens
  • Information and Instructions: the SLAMPAK brochure contains instructions for using the SLAMPAK as well as additional information on the Peli Lens and its benefits

How the Peli Lens Works

By placing high-powered prisms in a patient’s peripheral vision, the Peli Lens expands a homonymous hemianopia patient’s visual field and gives them more awareness of their missing peripheral vision.

Increased awareness can lead to a greater ability to avoid collisions and navigate around obstacles. Some patients are even able to drive again with the Peli Lens. 

The Peli Lens Process

Helping your patient get the Peli Lens is straightforward and simple. We recommend following the process outlined below for best results. 

  1. Determine Peli Lens is the Solution: if your patient suffers from stroke-related visual field loss, the Peli Lens will likely help them regain some lost vision
  2. Demonstrate the Peli Lens: Use the SLAMPAK to show your patients the Peli Lens in-office to demonstrate its benefits
  3. Fit the Temporary Peli Lens: the temporary Peli Lens is a cost-effective way for your patients to take the Peli Lens for a test run over a 4-6 week trial period
  4. Train with the Temporary Peli Lens: during the trial period, routine at-home training has been shown to increase the benefit a patient receives from the Peli Lens
  5. Order the Permanent Peli Lens: permanent Peli Lens peripheral prisms offer the greater field expansion and are far more durable than temporary lenses. We offer a variety of configurations to meet your patients’ needs.

*Our experience has been that deviating from this process results in poorer results for your patients. 🙁

The Temporary Peli Lens

The temporary Peli Lens is an affordable option for your patients to try before committing to a more permanent and expensive solution.

While temporary Peli Lens peripheral prisms expand visual field, they are meant to be used for a short period (4-6 weeks) and do not provide as much field expansion as permanent prisms.

We do not recommend that patients rely on temporary prisms for long-term use because they will not experience as much benefit as with permanent prisms.

The good news is that 74% of patients who complete a trial with temporary prisms wished to continue using the Peli Lens. Proper fitting and training leads to even higher success rates.

Peli Lens Prescription Solutions

There are a variety of ways to get the Peli Lens into your patients’ hands. We’ve outlined the most popular and useful in the section below, but if you need something different, let us know. We want to make sure your patient has the best solution for their needs.

SLAM: Single Lens Attached by Magnets

After decades of putting permanent Peli Lens prisms into every frame and lens imaginable, we developed a single lens solution that gives your patient the ease and convenience they need to use Peli Lens prisms on their terms.

Chadwick’s SLAM solution affixes to your patient’s existing glasses via three small magnets embedded on the side of the lens.

The benefits of Chadwick’s SLAM solution include:

  • Staying Power: our SLAM solution stays on the lens despite heavy shaking 
  • Durability: Our SLAM solution is quite durable and resists breakage
  • Comfort: Our SLAM solution is the least weighty of available options

The drawbacks of Chadwick’s SLAM solution include:

  • Aesthetics: having three magnets embedded in the lens of their dress glasses may be less aesthetically appealing than a single magnet in each lens

Magnetic Clip-Ons

Magnetic clip-ons are a two-lens solution that have one magnet embedded in each lens to allow the patient to affix the clip-on to their glasses frame. 

The benefits of magnetic clip-ons include:

  • Aesthetics: only one magnet on each side of the patient’s glasses is required for the clip-on

The drawbacks of magnetic clip-ons include:

  • Durability: the magnetic clip-on is fragile at the bridge
  • Staying Power: the magnetic clip-on can fall off if your patient encounters unexpected obstacles or unstable situations
  • Comfort: the combined weight of two lenses may be comfortable for some patients
