What Does this Test Do? Part 2: Topography

Corneal Topography rings

Corneal Topography Test

As you look into through the bright red colored rings, the topography machine creates a map of the clear front portion of your eye, the cornea.  Corneal topography allows us to detect irregular conditions of the surface that can’t be measured in other ways.

How does a map of the cornea help us evaluate your vision?

A healthy cornea is very important to your vision, because 77% of the eye’s focusing ability is done by the cornea.  Light enters the eye through the clear cornea. The shape and curve of the cornea plays an important role in the quality of vision. An eye with normal vision has an evenly rounded cornea, like a basketball.  An eye with an astigmatism has an unevenly curved cornea, more like a football.

Corneal topography is performed by projecting lighted rings onto the surface of the eye.  These rings are reflected back and measured by the instrument, and a map of the cornea is created.

Topography is an important tool in measurements for LASIK Surgery.  LASIK surgical correction changes the shape of the cornea to help patients see more clearly.  During LASIK, the shape of the cornea is changed to help images focus properly on the retina. Below you can see how the shape of the eye is changed with the laser after LASIK surgery. The photos show the same eye before and after LASIK.

Corneal Topography is just one of the testing resources that we use when treating our patients.  You can trust Moran Eye Associates to use the tools that we need to keep your eyes healthy, and your vision the best it can be.  If you have questions about your vision, contact Moran Eye Associates.  We focus on making vision clearer.

 

What Does this Test Do? Part 1 – AutoRefractor

What is the first test we do when you come into the office for a complete vision exam?

Autorefractor measures vision.

The Autorefractor measures your prescription

We take a measurement of your vision with the AutoRefractor.

Image used for measuring your prescription

Focus on the balloon!

When you take a seat at the autorefractor, we ask you to look into the device.  You will see a blurry hot air balloon at the end of a long straight road. As the balloon comes into focus, we measure your prescription.

We ask you to focus on the image (balloon) to keep your eye centered while we take measurements.  It only takes just a few seconds to measure using an autorefractor.  The balloon is at the center of the image, which aligns your eye perfectly for the test. 

When we use this machine, nothing touches your eye, and there is no puff of air!

The autorefractor provides an objective measurement of a person’s refractive error and prescription for glasses or contact lenses.  The device measures how light is changed as it enters your eye.

Calculating your glasses prescription

Better 1 or Better 2?

We don’t use the numbers from the device to order your prescription glasses or contacts. The autorefractor is just part of the process.  The information from the autorefractor is used as a starting point to determine your best prescription.  We take these numbers and dial them into the phoropter.

Here is where your opinion comes in.  As we cycle through lenses, we ask, “Is it Better 1 or Better 2?”  Your responses help us to pinpoint your best vision.  When we show you different choices, we aren’t trying to trick you!  We are showing you different options to find your best correction.

 

Recycle with Us!

If you care enough to recycle, we can help!

Bring your recyclable vision items into our office, and we’ll take care of the rest!

EYEGLASSES:

Recycle for Sight - Lions Club

We have a donation box in our office!

Bring your used glasses to the office. We have a collection box for the Lions Club “Recycle Your Sight” program.  The donated glasses are measured and then distributed to people who match the prescription.  Your donation can help a child to be successful in school, allow an adult to get a job, or a keep a senior citizen living independently.

We accept any type of glasses:  distance, reading and sunglasses too!  Safety glasses are also welcome.  If you have a glasses case, we can accept those too.  But don’t worry if you no longer have the case, we will wrap them so they arrive at their destination safely.

 

 

CONTACT LENS PACKAGING: 

While you may be aware that the contact lens boxes can be recycled through your municipal recycling program, did you know that the blister packs can be recycled too?

Save contact lens packaging

Recycle your contact lens packaging!

Our office takes part in a recycling program that accepts specialty packaging…including the foil and plastic of blister packs.  If you wear daily contacts, you are throwing out two containers each day.  Multiply that  times 30 days/month, 365 days/year…it adds up!  Especially when you consider how many patients wear contacts,

Don’t put them in the trash!  Collect your discarded containers and bring them into the office.  We will send them to our recycling program, and eliminate all of that waste.  Recycling small things can make a big difference.

PLUS…for every qualifying shipment a donation will be made to Optometry Giving Sight.  This nonprofit organization works to prevent blindness and impaired vision for those who do not have access to eye exams and glasses/contacts. For more info, visit: http://www.givingsight.org

Working together, we can make a difference!

Dr. Tang Teaches Eye Care to Local Students

Eyes in classroom

As part of Moran Eye Associates outreach program, Dr. Bianca Tang is visiting schools in Allentown, Bethlehem and Easton to teach young students about vision. Using crafts and a story time presentation, she explains to first graders how the eye works and the importance of protecting your eyes.

“It’s been fun working with the students. They are good listeners and are enthusiastic to share what they know about vision.”

She shows the students with pictures of different kinds of animal eyes. These pictures illustrate how although cat, horse, lizard, fish and lizard eyes all look very different, the design gives the animals the right vision for their environment.

She talks with the students about how to protect their eyes, so that they can have good vision that lasts them a lifetime. They discuss how wearing sunglasses protects your eyes from the UV rays of the sun. They also talk about the importance of eye protection while playing sports, and how everyone should wear eye shields at work and at home if there is a danger of something hitting their eye. Everyone attending gets a pair of sunglasses with UV protection to take home.

To help the students learn about the parts of the eye, the children do a craft project to make an eye of their own, complete with iris, pupil and lots of eyelashes!

If you would like Dr. Tang to make a visit to your school, please contact our office.

Allergies & Your Eyes

When you see the trees and flowers start to bloom, do you think “YAY, Spring!” or “OH, NO, Allergies!”?

Do your eyes feel itchy and irritated with seasonal allergies? Don’t suffer, come in for relief from the symptoms of allergy eyes. Dr. Moran and Dr. Tang can evaluate the best treatment for your allergy eyes that will help you enjoy the beauty of Spring.

SYMPTOMS OF ALLERGIC CONJUNCTIVITIS: Itching, redness, tearing and eyelid swelling. This condition is often accompanied by other signs of allergies, like a stuffy, itchy and runny nose.  It’s not contagious since it is caused by dust or allergens. Artificial tears, antihistamine eye drops, and medication can help relieve the symptoms.

If you use an over-the-counter (OTC) allergy medicine like to treat a runny or congested nose, while this medicine dries out our sinuses, it causes dryness in your mouth and eyes too! Use lubricating eye drops (artificial tears) when you take allergy medicines, and you give your eyes the moisture that they need to feel better and see clearly.

There are also specific OTC allergy eye drops that are can be used to treat irritated allergy eyes, but these drops aren’t suitable for long-term use. We don’t recommend drops that “get the red out”. These drops may offer a quick fix for red eyes, but they don’t give you any long-term benefits. In fact, you may become dependent on them, since they don’t solve your dry eye issues.

Our doctors can diagnose if there are other underlying causes for the eye irritation…it might not be just allergies. If you have a crusty, yellowish discharge you may have an infection that needs to be treated with antibiotics.

We are here to help you maintain good eye health and excellent vision no matter the season. Call us, text us, or fill out the form on this page to make an appointment with Dr. Moran or Dr. Tang.
