LASIK Follow Up Eye Exam Important Questions to Ask

 

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

 
You got LASIK and now your vision is great without glasses or contacts! Horray!  We manage many LASIK patients at our office and it is wonderful that we can change the lives of our patients with this procedure. However,It is important to point out that our eyes do change over time.  Eye exams are necessary to check for serious vision-threatening issues such as glaucoma, cataracts, and diabetic eye disease even if you had LASIK.  
 
If you have undergone LASIK chances are you were nearsighted. People who are nearsighted have an increased risk of retinal tear or detachment even after LASIK.  In addition, LASIK reshapes the front surface of the eye (cornea) by removing tissue to allow clear vision.  As a result, the thickness of the cornea is reduced and it is important to monitor for any progressive thinning (ectasia).  Yearly eye exams are important to monitor changes in the cornea as well as general ocular health.  Most vision changes are painless and gradual which may go unnoticed.  Annual eye examinations assure that potential sight threatening ocular health issues will be diagnosed sooner than later.

Color blindness is a condition where a person’s eyes cannot see color accurately and have difficulty telling colors apart.  It is estimated that 300 million people are colorblind worldwide.  One in 12 men are colorblind and one in 200 women are colorblind.  The genes that influence color vision are carried on the X chromosome and if these genes are abnormal or damaged, color blindness occurs.  

What causes color blindness?

The retina in the back of the eye contains three types of cone cells that correspond to three types of photoreceptors – red, green, and blue.  Red-Green color blindness is caused by the overlap of red and green photoreceptors in the eye.

How does color blindness affect the color blind?

Imagine going shopping for clothes without the ability to tell the difference between colors or when shopping for produce at the grocery store.  What if you wanted to cook a steak and couldn’t tell if the steak was done because you couldn’t see pink or red? These are some of the situations that people who are colorblind face everyday.  Not to mention work limitations, safety when driving and learning color-coded information in school.

What can be done?

EnChromaTM eyeglass lenses use special-filtering technology to help red-green color blind people see more of the full spectrum of color without compromising color accuracy or balance.  The lenses can be customized to your prescription for ultimate clarity. For some people the brain adjusts quickly and the effect is instant when first wearing the eyeglass lenses.  For others, it may take 10-15 minutes or more for the brain to adapt.

 It is back-to-school season and it is time to get your child new clothes, binders, backpacks, and pencils!  One of the most overlooked task before starting school is the eye exam.  Studies show that one out of every four children has a vision problem and only 50 percent of parents with children under the age of 12 have taken their children to the eye doctor.  
 

Many parents may be relying on vision screenings at school or at the pediatrician's office to check for vision problems.  The vision screenings are a good starting point,  but many conditions can be overlooked. During a vision screening letters are read at a distance (while looking for away).  However, reading vision is not evaluated and problems with reading can be easily missed.  A child could easily pass a vision screening, but not be able to see well enough to read a book.

The most common eye condition that can be missed is farsightedness, where things are clear far away but blurry up close.  Another condition is eye coordination, if the eyes are not focusing properly this will not be detected in a vision screening.  
A yearly eye examination is a must to ensure that children can learn to the best of their ability. Children’s eyes change very quickly which can have a negative impact on their performance in school.  The good news is that most vision problems can be corrected with early detection. Do not rely on vision screenings to keep your child’s vision healthy. Going to the eye doctor at least once a year is just as important as going to yearly medical appointments.

Retinoblastoma is a rare tumor of the eye that affects infants.  About 200-300 children are diagnosed every year.  The tumor affects the retina in the back of the eye and may affect one or both eyes.  Many parents first see signs of retinoblastoma after taking photos of their children and seeing a whitish area in the pupil in bright light.  

retinoblastoma

Symptoms 

  • A white color in the center of the eye (pupil) when light is shined in the eye, such as when taking a flash photograph
  • Eyes that appear to be looking in different directions
  • Eye redness
  • Eye swelling

In my career, I have seen a case of retinoblastoma in a young child.  This is a very difficult and unfortunate situation. I referred the child immediately to a pediatric ophthalmologist to have him evaluated. He will undergo a CT scan to determine how deep the tumor is and what the treatment should be. If the tumor is caught early enough, laser therapy can save the eye, otherwise the eye will have to be removed to prevent the tumor from spreading to the brain or the other eye. 

This case also underscores the importance of comprehensive eye examinations starting at 6-months of age.  I am part of a public health program called InfantSEE which provides a one-time no cost visual examination for children 6-months to age 1. Young children cannot communicate verbally if there is a visual problem, that is why early detection is paramount.

 Don't wait. Schedule your infant's eye examination today.

Myopia or nearsightedness is increasing in the general population.  Myopia is a condition where near objects are clear and far objects are not. 

  • Nearsightedness is increasing among  12-54 year olds have increased from 25% to 41% from 1970-2000.
  • It is estimated that myopia affects 1.45 billion people in the world, by 2020 the number is expected to grow to 2.5 Billion people.

Why is this happening?

Like most things in life, myopia is a combination of both nature vs nurture.  If both parents are nearsighted, the child has a 70% chance of being nearsighted.  The demanding scholastic environment and time spent on digital devices is implicated in the formation of myopia.  Children often hold these devices too close to their eyes and for hours at a time which can increase the risk of myopia.  

What can be done? 

Get your child outside

Studies show that time spent in the great outdoors can keep your child from developing progressive myopia.

Dilation drop

A very dilute dilating drop called Atropine can be used to treat progression of myopia.  The good news is the drop does not seem to cause any light sensitivity or near vision difficulty.  

Multifocal Contact Lenses

Using multifocal soft contact lenses can moderately slow down myopia.  The contact lenses are worn daily and designed to focus light on the back of the eye (retina) more accurately than traditional soft contact lenses.  This helps to reduce the progression of myopia.

Orthokeratology (Ortho-K)

  • No Daytime Contacts
  • No Surgery
  • No Glasses

The process of gently reshaping the front of the eye (cornea) while you sleep.  When the contacts are removed, wearers can see all day without having to wear glasses or daytime contact lenses.  Studies show that corneal reshaping (Ortho-K) can reduce the progression of myopia by as much as 40-50%.  

Parents are often surprised when I explain there are treatment options available to help prevent their children's eyes from getting worse.  In the past, the only option was to prescribe traditional glasses and contact lenses resulting in increasing myopia year after year.  Using the latest technology and research we now can employ various modalities to help our children's eyes from getting worse.  Doing so helps me sleep better at night.
