 AmbioDisk Bright


By Michael Duong, O.D., F.A.A.O

Dry eye is a disease that causes irritation, redness, burning, and stinging.  There are many treatment options for dry eye including over-the-counter and prescription eye drops. A new treatment called AmbioDisk, about the size of a small contact lens contains amniotic membrane which has regenerative properties that can help bring the eye to a normal state.  The disk is placed on the front surface of the eye called the cornea.  Clinical studies have shown that AmbioDisk can heal the eye, soothe pain, and improve vision.  The disk can be inserted and removed in office.  

The disk is carefully placed on the cornea, then a soft contact lens is placed over the disk to keep it in place. Over a 5-7 day period, the nutrients from the disk dissolve into the cornea to help heal the eye.  The purpose of AmbioDisk iis to bring the eye back to a normal state where eye drops and conventional treatments can become more effective in the treatment of dry eyes.  

AmbioDisk can be used for the following conditions on the cornea:

  • Non-Healing Epithelial Corneal Defects
  • Corneal Erosions
  • Acute Chemical / Thermal Burns
  • Eye Infections
  • Dry Eyes

If you have any questions about the AmbioDisk treatment, please do not hesitate to contact our office for more details.

According to the American Academy of Allergy, Asthma & Immunology, 50 million people have eye allergies affecting 30% of adults and 40% of children.  When allergens affect the eyes it causes red, itchy, and watery eyes.  The most common allergens that cause eye allergies are pollen, mold, dust, and pet dander.  

 What can you do to survive allergy season?

1.  Try to avoid or limit your exposure to allergens.  If you are outdoors, wear wraparound sunglasses and drive with the windows up.  If the pollen count is high, try to stay indoors with the air conditioner running.  

2.  Use artificial tears or over-the-counter antihistamine eye drops to help reduce itchy and swelling of the eyes.   Ask your eye doctor which type of treatment is best for you.  

3.  Try not to rub your eyes because this causes more itching!  Rubbing your eyes causes histamine to be released and causes runny nose and itchy eyes.   

4.  If you are a contact lens wearer, consider switching to daily disposable contact lens wear.  Allergens adhere to the lenses which are disposed at the end of the day with daily disposable contact lenses.  

5.   Make sure you wash your face and take a shower before bedtime to remove dirt and allergens from your eyes and face.

 If over-the-counter medications do not reduce eye allergies, prescription strength eye drops can be prescribed in severe cases.  See your eye doctor to determine which medicated treatment is most effective in treating your eye allergies.

Eye problems can be easily missed in the early stages of infancy.  The American Optometric Association recommends a baby’s first eye exam at 6-months of age.  The testing that is performed are visual acuity, excessive amounts of nearsightedness, farsightedness, and astigmatism, evaluate eye teaming and eye alignment.  In addition, the health of the baby’s eyes will be evaluated to rule out ocular diseases.  Although rare, most eye conditions are painless and can be easily missed.  

One in every ten children are at risk from undiagnosed eye and vision problems, yet only 13 percent of mothers take their babies for an eye examination.  Early intervention is crucial to prevent compromise to vision development in infants.  The InfantSEE program provides a one-time, no cost eye and vision assessment for babies 6 to 12 months old.  I am proud to be an InfantSEE provider.  The good news about a trip to our office is that there are no shots or cold stethoscopes.  It is recommended that an appointment is scheduled when the baby is well fed and not during nap time.  

About 9 months ago, Landon was brought to our office for an eye examination by his mother.  Unfortunately, a tumor called retinoblastoma was found in the back of his right eye and left eye.  Retinoblastoma is a rare tumor that affects 200-300 children every year.  He has been undergoing chemotherapy and radiation at UCSF in order to preserve his vision.  

You can follow Landon’s story here on Facebook.  https://www.facebook.com/LandonStrongRB/

I keep his chart on my desk as a reminder of the responsibility that I have to protect and preserve sight.   To locate the nearest InfantSEE provider near you go to www.infantsee.org or call (888) 396 - 3937.

Myopia or nearsightedness is the inability to see things far away while things up close are clear.  In the U.S., about 145 million people or 45% of have myopia (2010).  It is estimated that by the year 2050, 200 million people will have myopia.  Complications of myopia include cataracts, glaucoma, and retinal detachment.  The table below is a summary of myopia risk.

How do we slow down myopia progression?

Orthokeratology (Ortho-K) is an FDA-approved process of wearing rigid gas permeable contact lenses to reshape the cornea while sleeping at night. Upon wakening the contact lenses are removed and clear vision can be achieved all day without the use of traditional contact lenses or glasses.  Ortho-k lenses are used to correct nearsightedness (myopia) with mild to moderate amount of astigmatism. Ortho-K is a reversible process; discontinuation of the lenses will result in loss of reshaping of the cornea.  Just like the use of a retainer after wearing braces on teeth,  the lenses must be worn in a nightly basis to achieve effectiveness.

 Ortho-K is FDA approved for Myopia up to -6.00 and Astigmatism up to -1.75.  However, with new technological designs up to -10 can be achieved (Off-label). 


Is Ortho-K right for me or my child?

Ortho-K was developed for children and adults who are nearsighted or cannot see things at a distance without corrective lenses. Nearsightedness can develop more rapidly during childhood.  Studies show that Ortho-K can reduce the progression of myopia by as much as 40-50%, reducing the risk of cataract, glaucoma and macular degeneration.


Ortho-K is a great option for those who:

  • Play sports
  • Want freedom from daytime contacts and glasses
  • Work in dusty environments
  • Cannot wear daytime contacts due to discomfort


Is Ortho-K safe?

Ortho-K is a very safe process of wearing rigid gas permeable contact lens to correct vision.  The risk of infection is less than traditional daily soft contact lenses.  It is important to follow-up on a regular basis and comply with the cleaning regimen prescribed by your eye doctor.  

Below is a video of one of our Ortho-K patients, Harshita.  She has been in Ortho-K since 2012, and had noticed that her vision was not as clear with her previous Ortho-K lenses from another office.  She came to our office and we were able to fit her with one of our custom Ortho-K lens design to help her see clearly throughout the day while slowing down her myopia!  Her vision is 20/20 throughout the day.

Chronic dry eye (CDE) is a disease that causes, overtime, a decrease in the production in the quality and quantity of tears.  

Symptoms of Chronic Dry Eye include:

  • Dryness / Itching
  • Burning / Stinging
  • Watery eyes
  • Light sensitivity
  • Problems wearing contacts
  • Feeling like something is in your eye
  • Blurry vision


CDE is more common in people 50 years of age or older and occur more frequently in women than men.  However, the rise of digital device use in the form of smart phones, tablets, and computers is causing dry eye in young adults.


Blink Rate

When looking at a digital screen, the blink rate decreases by 50%.  In addition, our eyes do not perform a complete blink while looking at digital devices.  There are tiny glands called meibomian glands at the base of our upper and lower eyelids near the eyelashes.  Each time a blink occurs, oil is secreted from the glands.  The oil makes up the top layer of tears and prevents the tears from evaporating.  If an incomplete blink occurs, not enough oil will get onto the front surface of the eye. The tears evaporate at a higher rate leading to dry eye symptoms.



When the meibomian glands are not functioning properly, the oil becomes thick and backs up into the gland.  This causes the gland to atrophy and ultimately disappear. The image below shows the different stages of meibomian gland dysfunction using a special camera called a Meibocan.  80% of dry eyes is caused by meibomian gland dysfunction.  It is important to receive a baseline Meiboscan to determine if you have early signs of meibomian gland dysfunction.  





Blink exercises - every 20 minutes look 20 feet away and perform a hard blink for 10 seconds.  This will help secrete the oil from your glands and prevent them from becoming plugged up.   

Artificial Tears - Using oil-based artificial tears to prevent tear evaporation 2 - 4 times a day.  

Heat mask - a special mask can be prescribed by your eye doctor.  This mask is used 1-2 x a day for 10 minutes at a time to help open the meibomian glands to secrete oil.  

Expression and debridement - performed in-office.  This the process of evacuating plugged glands by mechanically expressing them with special forceps.  After this is done, a special brush is used to clear debris from the lids and clean the meibomian glands.  

If you are someone you know is suffering from dry eye disease, seek help by scheduling a dry eye evaluation at our office today.
