Reach Your Full Potential With Vision Therapy and Rehabilitation

London Visual Development Centre is a clinic that provides vision therapy, neuro-visual rehabilitation, and sports vision for children and adults with vision problems that interfere with school performance and everyday life. This includes cross, wandering, or lazy eyes, as well as neuro-optometric rehabilitation for brain injuries such as concussions. We also provide sports vision training for athletes who are looking to gain an edge through visual performance.

Located upstairs from Highbury Huron Optometry, we have many success stories helping our patients work through vision problems so that they can be their best. Dr. Khamis is very interested in vision therapy and is dedicated to helping people with vision issues.

Vision Therapy

Vision therapy is a doctor prescribed set of vision treatment procedures that cannot be corrected by glasses or contact lenses. It is done in-office and supplemented by home therapies. Vision therapy is comparable to physical therapy for the eyes where vision disorders are corrected to improve patients' visual function and performance. Vision therapy can be described as “training the brain” as it looks to provide permanent life-long changes to achieve clear comfortable binocular vision.

Children can have difficulty in school performance if they have problems with things such as eye-tracking, eye teaming, and eye focusing, and this can make school and reading extremely difficult and can result in poor school performance. At the London Vision Development Centre, we have the hi-tech equipment to provide individual reading analysis on each of our patients and help treat the above condition. Vision therapy also helps with lazy, crossed or wandering eyes. 80% of what we comprehend and see relies on our vision and therefore vision therapy not only helps children but is effective in adults as well.

Neuro-Visual Rehabilitation

Neuro-optometric rehabilitation is a subset of vision therapy that deals with visual disorders that are a result of concussions, brain injuries, development delays or other neurological disorders.

An evaluation will involve in-depth testing which will evaluate how well your vision functions, and to what degree it is impacting your daily life and activities, including reading, playing sports, driving, balance and movement (tying shoes, filling up a glass of water, etc).

Neuro-optometric visual evaluation is unique because in addition to the traditional eye exam and basic binocular vision skills, and eye health, we do performance testing to see how the visual process is interacting with other sensory feedback mechanisms.

After a brain injury, visual symptoms can range from being very subtle to dramatic. The very subtle visual symptoms may be the most frustrating because they require very specialized testing to detect, so the patient often feels like no one believes them or can tell what they are going through.

Sports Vision

Have you ever wanted to improve your batting average, lower your golf score, improve your save percentage, or just play your favourite sport better?

Sports vision is the practice of examining and managing the visual needs of a patient. It includes:

  • Providing appropriate correction

  • Assessment and remediation of functional vision inefficiencies

  • Performance enhancing vision training

One of our main goals in sports vision is to slow the game around you by speeding up your visual processing time.

  • Vision provides the athlete information about where and when to perform, where to go, how to react; things that cannot be trained by lifting weights at the gym. 80% of the information we get around us is from the eyes (visual).

Starting with a vision performance evaluation we then go on to create individual vision performance enhancing plans focusing on things such as eye-hand coordination, depth perception, eye movements, decision making, peripheral vision and eye-body awareness. We have worked with many athletes across many sports from hockey, baseball, football and golf to olympic skeet shooting and high jump.

  • Did you know? A major league batter has approximately 400 ms between the release of the pitch and the time the ball arrives at the plate.

  • The swing takes approximately 150 ms to complete and the batter has approximately 250 ms to process the visual information from the pitch to determine the appropriate response. We focus on improving that visual information processing speed.

Vision Problems that Interfere with School/ADHD

Did you know? 60% of children with learning problems have visual problems (AOA).

Increases with kids with special needs!

Vision problems can make it more difficult for children to read, learn, remain on task and succeed in school. It is important for parents to be fully informed about their children’s vision.

  • 1 in 10 children has a vision problem significant enough to impact learning (5 million in the US alone)

  • “20/20” only means a child can see at distance but may lack skills needed for learning, such as focusing, coordinating, and tracking

  • Typical vision screenings miss at least 50% of vision problems

  • Children with vision problems can be misdiagnosed with ADD/ADHD

Problems Focusing Eyes

For kids in school, problems with focusing means they will get tired when reading, words will start to get blurry the longer they read, they won’t be able to read for very long or have trouble copying things from the smart board. Print can initially go from being clear to looking like this start looking like this:

This can also lead to headaches and eye strain making reading and school work very difficult.

Problems Focusing Eye

Tracking Problems

When we read our eyes follow along print. This is called tracking.

Children who struggle with tracking can lose their place when reading and their eyes can jump around can sometimes even skip lines. This can jumble up text and scramble up words making it very difficult to comprehend what they read. At the London Vision Development Centre we use the latest technology and have an instrument called the Readalyzer that can let us know exactly where the child’s eyes are pointing when reading as well as provide a demonstration to the parents afterwards where the child’s eyes were jumping when reading.

Eye Teaming

Eye teaming can create double vision, especially if reading small print for a large period of time. In order to keep single vision, one must point their eyes at the same point on a page. If there is an eye teaming problem than as the eyes tire the ability of the eyes to “team” breaks down and the eyes end up aiming at different parts of a page resulting in the following

Not all children with eye teaming issues see double, most will stop reading when their eyes become tired and things split into two. They take vision breaks, to avoid close work – daydreaming, talking in class, going to the bathroom, getting a drink. Because they are off task and these children often get suspected of having ADD/ADHD when the real issue is their vision.

Eye Teaming

The Myth of 20/20

Many people think if you have 20/20 you have perfect vision but this is not true. 20/20 vision means you can see the size of the letter you are supposed to at 20 feet. If your child’s vision isn’t sharp enough to pass this eye test then glasses or contacts will be prescribed.

However clear vision is just one of the visual skills needed for success in school. In addition to seeing clearly, children need to be able to focus up close for a long period of time, as eyes have to work a lot harder to read than they do at distance, and school work requires very special visual skills. 80% of what we learn is processed visually. Children with poor visual skills struggle in school, especially with the ability to read and pay attention. One out of every four children has a vision problem that hurts their ability to learn, read and remain on task.

Megan’s Story

During optometry school I started to notice that I was experiencing increased headaches and fuzzy images when reading for extended periods of time. When I was fatigued and listening to my professor’s I would notice two professors for a long period of time after I blinked. As a child I knew I hated reading long chapter books and avoided reading for long periods of time. For example, I acted as if I hated vegetables so I just never ate them. Problem solved right? As I chose a career in optometry there was no working around the very long nights of studying and reading so I was forced to face my symptoms that I honestly had repressed to childhood memories. It was not until talking with my vision therapy teachers that I realized I had an eye turn called an intermittent esotropia that manifested when I fixated for long periods of time. Without the knowledge of my teachers who specialized in vision therapy, I never would have known to head down this path. I started right away at vision therapy and this is where my journey started with Dr. Khamis. Realizing board exams would be approaching soon and I knew I needed to be able to withstand long hours of the test. Dr. Khamis was very thorough in making sure my diagnosis matched all my therapies to maximize positive results. He was very patient in working with me and I owe him all the thanks to being able to read for extended periods of time, not getting tired during long lectures and reduced headaches.

Dear Dr. Khamis

I wanted to take a moment to thank you and your staff for all of your help with the sport vision screening here at NSU. Every year me and my staff treat multiple concussions and a quality sports vision screening can help us to focus both mandatory and preventative treatments for our student-athletes.

The results you provided me for each student-athlete were great! The easy to follow, one-page assessment provided me with a detailed breakdown of each person’s vision, hand-eye and foot coordination, focusing ability, eye speed, and eye teamwork. This has allowed us to specifically tailor exercises for each person to address their areas of needs. All the student-athletes especially like using the Nike Sparq strobe glasses during some of their drills.

In closing, I would like to again say what a pleasure it was to work with you and your staff! The information you were able to provide us was invaluable and as we implement more of the sports vision training program into our preventative activities, I expect to see a decrease in the amount and severity of concussions across all sports.

Bri’s Story

I was in a car collision in May of 2017 which resulted in a life altering concussion that lasted for 6 months. I was basically unable to do any of the things I enjoyed doing or was required to do. I could not walk my dogs, do laundry, clean the house, cook a meal, read a book, use a computer, watch TV, have meaningful conversations, concentrate on any task that required thought, I was unable to work and I could only drive very short distances. I was extremely frustrated and upset that my life had come to a halt. I was referred by my optometrist to Dr. Khamis and his team, who have been instrumental in helping me regain my independence and my life.

With their support and guidance I have recovered my ability to read, write, walk my dogs, watch TV and use the computer. I just recently was given the go ahead to return to work where I can actually feel like a productive member of society again. I no longer feel nauseated when I try to read- I can actually read a book for as long as I want. This is a huge accomplishment as after my concussion I could not even read a sentence without becoming nauseated, developing a headache and dizziness. I can drive as far as I want without having to plan routes where it’s avoiding turns which makes life much easier and takes less time! I have returned to my old self!

Having Joan and Dr. Khamis there to support me and encourage me along the way has been a true blessing. Even when I struggled with the tasks they gave me, their reassurance helped me push through all of the difficulties I faced. Thank you for helping me to get my life back!

Larry’s Story

I wish to thank the great staff at London Vision Development Centre at the Highbury Huron Optometry here in London Ontario.

The three individuals Dr Khamis, Joan and Kopila. treated my post concussion problems and helped re align my eyes and brain connections.

Weekly treatments over the first four months in 2019, certainly helped link my brain with my two eyes I had experience a car accident in 2018 in which my head smashed out the side driver window and caused difficulty in linking my brain and two eyes.

I recommend them for helping individuals with post concussion difficulties.

The vision therapy treatments are easy to do, they only takes about 15 mins a day to do and are beneficial. I had a concussion years ago and have had lingering side effects since.

This helped.

Ella's Story

My sport vision training experience was fun. I liked that half of the sessions were in the room at the office and the other half were in the gym. In the office I found every exercise was very fun, especially the virtual reality. In the gym I found that they made the exercises specific to hockey goalie, which was very helpful. Also, Dr. Khamis prescribed me contact lenses which really helped my game. I didn’t even know I needed them.
