Answering: How does light-based somatic work differ from EMDR, and when might each one fit?

Estimated reading time: 10 min read

If you have been reading about trauma and anxiety, you have almost certainly come across EMDR, and you may now be wondering how a body-based, light-led option compares. Here is the honest starting point. EMDR is an established, evidence-based psychotherapy, recommended by mental-health services for post-traumatic stress. Quantum Photo Somatics is something different in kind: a complementary somatic modality, registered with the International Institute for Complementary Therapists (IICT) since 2019 and developed by Dr Michael Christian across 33 years of clinical practice and more than 43,680 documented sessions. This article does not argue that one is better than the other. They sit in different categories, with different evidence behind them, and the useful question is not which wins but which fits what you are looking for.

Dr Christian holds a PhD in integrative medicine and is board certified with the Board of Integrative Medicine in North America. He is deliberately unconventional in how he thinks about the body, and he does not hide it. What he offers is not a rival therapy dressed up in new language, but a different lens entirely, one that begins with the visual system rather than with memory processing. This guide lays both approaches side by side, tells you plainly where the evidence sits, and helps you judge which one is worth your time, or whether the answer is both.

Key Insights

• EMDR is an established, evidence-based psychotherapy for trauma and PTSD. Quantum Photo Somatics is a complementary somatic modality in a different category, with no randomised controlled trials behind it.
• The two are not competitors. EMDR works with memory and thought under a trained therapist; in Dr Christian’s model, QPS works with the timing between the visual, neurological and somatic systems, a state he calls phase coherence.
• We describe QPS as something that “may support” the nervous system. It does not treat or cure any condition, and it is designed to sit alongside psychological and medical care, never to replace it.

What EMDR Is, and Why It Is Well Regarded

EMDR stands for eye movement desensitisation and reprocessing. It is a structured psychotherapy, delivered by trained mental-health professionals, in which a person recalls a distressing memory while following a form of bilateral stimulation, most often side-to-side eye movements guided by the therapist. The working idea is that this process helps the brain reprocess a memory that has become stuck, so that it loses some of its emotional charge and no longer intrudes in the same way.

Its standing is not in question, and it would be wrong to imply otherwise. According to beyondblue, EMDR is listed among the most effective, research-backed treatments for post-traumatic stress, alongside cognitive behaviour therapy and exposure-based approaches. It is recommended within clinical guidelines, it is delivered inside the regulated mental-health system, and it has a substantial body of trials behind it. If you are dealing with diagnosed PTSD or significant trauma, EMDR is exactly the kind of evidence-based psychological care a GP or psychologist may point you toward, and nothing on this page is a reason to look past it.

We want to be clear about that respect up front, because the rest of this article draws a distinction, and a distinction is not a criticism. Quantum Photo Somatics does not compete with EMDR for the same job. It occupies a different category of practice altogether, and understanding that difference is the whole point of comparing them honestly.

EMDR and QPS Side by Side

The clearest way to see the difference is to lay the two approaches out together. The table below sets them next to each other on the questions that matter most: what each one is, how it works, what it is designed for, and where its evidence sits. Read it as a map of two different territories, not a scoreboard.

Read across the rows and a pattern appears. EMDR is a defined clinical treatment for a defined problem, backed by trials and delivered inside the regulated system. QPS is a complementary exploration of how the body coordinates itself, offered within a registered and insured framework but without the trial evidence that sits behind a psychotherapy. Both use the eyes in some way, which is where the surface resemblance ends and the categories part.

Where Dr Christian’s Approach Genuinely Differs

It is easy to notice that both EMDR and QPS involve the eyes and assume they must be doing the same thing. They are not. In EMDR, the eye movements are a form of bilateral stimulation used to help the brain reprocess a specific memory. The eyes are a tool in service of working with that memory. In Dr Christian’s model, the visual system is not a tool for reaching a memory at all. It is the subject of the work itself.

Here is where his thinking becomes genuinely his own. He proposes that a good deal of persistent distress is less a memory problem and more a timing problem: the visual, neurological and somatic systems falling out of step with one another, a state he calls a loss of phase coherence. When those systems are no longer arriving together, he argues, the body reads the mismatch itself as a low-grade threat and holds a background hum of alarm. Quantum Photo Somatics is the method he built from that idea, using calibrated light and prism to bring the visual system back into closer timing with the rest of the body. He describes this as redirecting the body’s process rather than reprocessing a particular event.

This is a bold framework, and he treats it as one. He has set it out across two books, In Focus in 2016 and From Seeing to Being in 2025, and refined it over 33 years and tens of thousands of documented sessions. The visual system is a defensible place to begin. As Victoria’s Better Health Channel explains, the somatic nervous system carries sensory information from the eyes, ears, skin and muscles to the central nervous system, while the autonomic nervous system regulates the body without conscious effort. The eyes are not a separate department, in other words, but a constant stream of information feeding the systems that govern tension and the body’s automatic responses. Where EMDR works with the content of a memory, QPS works with the timing of the systems that colour how safe the present moment feels.

When Each One Fits

Because the two occupy different categories, the question of which fits is less about your preference and more about what you are dealing with. The following is a plain guide, not a diagnosis, and where trauma is involved the right first call is always a GP or a qualified mental-health professional.

EMDR is likely the better fit when you are dealing with diagnosed PTSD or a specific traumatic memory that keeps intruding, when you want an established treatment with trials behind it, and when you are looking for care delivered inside the regulated mental-health system by a registered therapist. If a distinct event or set of events sits at the centre of your distress, EMDR is designed precisely for that, and it is the kind of evidence-based option a clinician may recommend first.

Quantum Photo Somatics may be worth exploring when talk-based and memory-based work has helped your thinking but something still feels lodged in the body, when you are drawn to a body-based, light-led approach that does not require you to revisit a specific memory, or when you want a consent-led modality where touch is always optional. Many people who come to QPS have already tried the usual routes and are curious about a different lens, one focused on how their systems coordinate rather than on a single event. It is not a replacement for psychological care, and it is not for someone in crisis, but as a complementary exploration it may support the nervous system while your existing care continues.

The two are not mutually exclusive. Some people work with a psychologist on EMDR and separately explore a body-based modality, and there is nothing contradictory in that. QPS is designed to sit alongside conventional care, never to displace it, which means choosing to explore it never asks you to give anything else up.

The Honest Line on Evidence

You will have noticed careful language all through this page. We say EMDR is established and evidence-based, and we mean it plainly. We say QPS “may support” the nervous system, and we mean that just as plainly. The difference in wording is not modesty for its own sake. It is an accurate reflection of two different evidence bases, and pretending otherwise would do you a disservice.

Quantum Photo Somatics is a complementary modality, not a medical treatment, and there are no randomised controlled trials establishing it as a proven therapy. Dr Christian does not claim there are. In Australia, the law is strict about what a complementary practitioner may say, and rightly so, because the field has more than its share of people promising cures they cannot deliver. He has built the opposite kind of practice: registered with the IICT, insured, and careful. Holding to “may support” is not a hedge he resents. It is the honest description of what a complementary modality can offer, and it is one of the clearest ways to tell a serious practitioner from someone selling certainty. If anyone promises that a light-based session will cure trauma, that is the moment to be more cautious, not less.

So here is the deal we are offering you. We will tell you plainly what Dr Christian believes and why, in his own bold terms, and we will place it honestly next to a psychotherapy that has the trials he does not. We will not dress his framework up as proven medicine, and we will always say that QPS belongs alongside your medical and psychological care rather than in place of it. If that kind of straight talk is what you were hoping to find, a first conversation is a low-pressure place to begin.

Frequently Asked Questions

Q: Is Quantum Photo Somatics a type of EMDR, or a replacement for it?

A: No to both. EMDR is an established, evidence-based psychotherapy for trauma, delivered by trained mental-health professionals. QPS is a complementary somatic modality in a different category, registered with the IICT since 2019, that does not treat or cure any condition. They both involve the eyes, but they are doing different things, and QPS is designed to sit alongside psychological care, never to replace it. If you are dealing with diagnosed PTSD, EMDR is the kind of care a clinician may recommend first.

Q: They both use the eyes. Isn’t that the same idea?

A: It is an understandable assumption, but no. In EMDR, guided eye movements are a form of bilateral stimulation used to help the brain reprocess a specific memory. In Dr Christian’s model, the visual system is the subject of the work itself, and QPS uses calibrated light and prism to support the timing between the visual, neurological and somatic systems, a state he calls phase coherence. One works with the content of a memory; the other works with how the body’s systems coordinate.

Q: Does QPS have the same evidence behind it as EMDR?

A: No, and we will not pretend it does. EMDR is listed by beyondblue among the most effective, research-backed treatments for post-traumatic stress, with substantial trials behind it. There are no randomised controlled trials establishing QPS as a proven therapy. What QPS has is Dr Christian’s clinical model, more than 43,680 documented sessions, and registration within an insured, internationally recognised complementary framework. Those are different kinds of standing, and it is honest to say so.

Q: Can I do both?

A: Yes. Some people work with a psychologist on EMDR and separately explore a body-based modality such as QPS, and the two do not conflict. QPS is designed to complement conventional care, so exploring it does not ask you to stop anything you are already doing. If you are unsure what is right for your situation, keep your GP or therapist in the loop.
