A Pentacam is a non-invasive and non-contact diagnostic instrument that provides a 3-dimensional image of the anterior portion of the eye. It works by illuminating a thin layer within the eye. The cells in the eye are not entirely transparent and scatter light and in doing so they create a sectional image that is then photographed. While swiveling around the eye, the camera device generates a series of radially orientated images of the interior eye chamber.

All of the images are put together to create a three-dimensional model of the entire anterior chamber and data regarding the elevation, curvature, pachymetry, depth of the anterior eye chamber and other important information in the well-known form of colour maps.

At Total Optical, we have partnered with laboratories that provide lenses with superior features so that our patients may see as clearly as possible. For example, Mau Jim have a suite of lenses that come with high quality features such as:

High contrast: When you choose Maui Jim eyeglasses with proprietary High Contrast Lens, you’ll see the difference right away — day and night. More contrast makes it easier to read fine print and makes colors appear more vivid and crisp. Driving at night is safer and more comfortable, thanks to less glare from headlights and streetlights.

Reduce blue light: Every pair of Maui Jim polarized sunglasses and Maui Blue Light Protect clear lenses filter out high energy visible (HEV) light. Better known as bothersome blue light — and produced by the digital screens many of us stare at for hours every day — HEV causes eyestrain, headaches, tired eyes and blurred vision. Put a stop to all that with all-day blue light protection.

Say no to UV: All Maui Jim lenses — clear lenses and polarized sun lenses — deliver 100% UV protection. Why is that important? UV rays can cause sunburn of the eyes (ouch!), cataracts, macular degeneration and cancer.

Prevent skin cancer: Did you know 5-10% of skin cancer occurs around the eyes? Maui Jim polarized sunglasses hold the Skin Cancer Foundation Seal of Recommendation. Wear them every day — even on overcast days — to protect the eyes and surrounding skin.

THERE ARE LOTS OF ACTIVITIES THAT CAN HELP YOUR CHILD TO IMPROVE THEIR VISUAL SEQUENTIAL MEMORY SKILLS:

-Play word games such as hangman, word searches or crossword puzzles.

-Practise memorising sequences of objects, shapes or colours. For those not yet familiar with letters or words, visual sequential memory can be developed by stringing bead patterns on necklaces, memorising sequences of shapes or by remembering a series of objects (e.g., a shopping list).

-Talk about your day with your child and then recall each other’s events.

-Practise finding patterns in letters, numbers, shapes or objects within a sequence to help remember it. It may help to look for patterns or repeated parts. This streamlines the memory process by reducing the number of units the child needs to remember.

-Use prepared flash cards or pieces of paper with pictures of familiar objects pasted on them, one object per page. Begin by showing your child three flash cards sequentially, allowing one second for each card, then ask the child to name the items in the order they were seen. As sequential memory improves, increase the number of cards for each round.

-Use visual images to help your child remember information in a particular order. A useful activity for children is to place a number of images (three or four to begin with) that relate to a specific subject and ask them to tell a story about the images, linking one to the next but using the correct name for each image. Remove the cards and take a short break, then ask your child to retell the story. Increase the number of images displayed as your child becomes more confident.

-To build auditory sequential memory, play a game of repeat after me. For young children, use one syllable words they easily recognise, beginning with two words, such as “cat” and “mouse”. Ask the child to repeat the words in the same order that you said them. Increase the number of words repeated one at a time. How many words can you remember correctly?

-You can use clapping or stomping patterns with older children. Clap a specific sequence, such as “clap-clap-pause-clap,” and ask the child to repeat it. As the child masters sequences of four beats, increase to longer sequences.
