It was my turn to be on the other side of the exam chair.
I was sitting at home on a Sunday afternoon, when I first saw sparks of light out of the corner of my right eye. At first, they occurred a few times an hour. By Sunday night, they were happening a few times a minute. They moved in curved arcs along my peripheral vision.
Since I happen to know people trained in eye care, I sent a text to the office staff to tell them what was happening.
They asked me all of the right questions:
- Did you sustain an injury to the eye? No
- Was there a curtain falling across my vision? – No
- Did you see a sudden shower of floaters? – No
- Any loss of vision? – No
- Any pain? – No
Dr. Moran asked me, “What would you tell a patient who called with these symptoms?” I answered, “We would tell them to call us if it gets worse, or they can answer YES to any of the above questions. We would then schedule them for a dilated exam the next day.”
I understood everything that I was told. It was a “classic textbook” issue. I have spoken to patients who were experiencing the same symptoms, and explained that they should come in for an exam, but not to worry. Flashes can be a common occurrencesisipisi.ccsisipisi.ccsisipisi.ccsisipisi.cc.
But…I must admit that it felt different being the patient. Even though I understood what was happening, I felt better after checking in with Dr. Moran and the rest of the team.
By the next morning, the symptoms had stopped. I had a very thorough dilated eye exam, and everything was normal. I knew that the sparks of lights were caused by the vitreous tugging on the retina, which is common. It is seen more often in older adults. I am 58, so I fit that profile. I knew that the issue was most likely age-related.
When you are having an issue with your eyes, don’t delay, contact our office.
We will ask you the key questions that mean the difference between an emergency, or something that can wait until you can come into the office for an exam.
You can feel confident that you are in good hands with Dr. Moran and the staff at Moran Eye Associates. We take your concerns seriously, because we know what it is like to be on the other side of the exam chair.
P.S. Almost two months later all is well. I am very aware of the importance of follow up exams, and will make sure to see my ophthalmologist regularly! Bobbi
As part of your comprehensive eye exam, we check the pressure of your eye, the Intraocular Pressure (IOP). This test, called tonometry, is one way to see if you are at risk for glaucoma. Regular screenings are a simple way to monitor your eye health. Early detection is essential in the treatment of glaucoma, since many times there are no symptoms with increased pressure, unless it is sudden.
UNDERSTANDING EYE PRESSURE:
Inside the eye, there is a cycle of fluid production and fluid drainage. This fluid, in the front part of your eye, is called the the aqueous humor. The aqueous humor nourishes your eye and helps it to keep its shape. If this cycle is out of balance, and more fluid is produced than is able to drain effectively, IOP increases. Over time, this Increased eye pressure may cause damage to the optic nerve. A general guideline for normal eye pressure is between 10 and 21 mm/hg.
HOW WE MEASURE EYE PRESSURE:
In our office, we measure eye pressure by instilling a drop that numbs your eye. Using a blue light, we then use an applanation tonometer that gently touches the surface of your eye. This painless test is a very effective way of measuring your pressure. It is helpful for the patient to relax and breathe normally while we perform this testsisipisi.ccsisipisi.ccsisipisi.ccsisipisi.ccsisipisi.cc.
Although there are many other ways of measuring eye pressure, many people are familiar with the “puff of air test”. This test, called non-contact tonometry, uses a rapid air pulse to flatten the cornea. Your pressure is measured by detecting the force of the air against your eye. Although we don’t use this process, often when we ask patients them to “put your chin in the chin rest and forehead against the band” they worry we are going to puff air at them. They don’t seem to like it!
We can’t emphasize enough the importance of comprehensive eye exams. It is especially important to have an eye exam if you have a family history of eye disease, diabetes or high blood pressure. The best way to protect your vision is to come in for an exam, where Dr. Moran will evaluate your risk for disease and advise you of the optimal schedule of visits to protect your eye health.

Patients are curious about what happens during LASIK surgery.
Dr. Moran knows that a well-informed patient makes the best medical decisions. Understanding what happens during LASIK can lead to a more calm and comfortable experience. We’ve highlighted the most commonly asked questions about all-laser LASIK with Intralase. The best way to find out if you are a candidate for this vision correction procedure, is to come in for a free one-hour consult appointment.
LASIK vision correction is a 2-step process.
- First, we create the flap in the surface of the cornea.
- Second, we lift the flap and apply laser treatment to reshape the corneal tissue.
What is Intralase?
A: The IntraLase Method uses laser light to create a flap in the outer layer of your cornea. The laser creates an even layer of microscopic bubbles under the corneal surface. The flap is hinged, like the page of a book. Dr. Moran then lifts the flap by gently separating the tissue where these bubbles have formed. After the flap is lifted, Dr. Moran moves to the second step of the procedure, applying the laser treatment to reshape the corneasisipisi.ccsisipisi.ccsisipisi.ccsisipisi.cc.
What makes using Intralase technology unique?
A: The IntraLase Method uses a laser to create the flap. This laser-guided application creates a smooth even surface after your flap is lifted.
Are there benefits to using the Intralase Method?
A: Although the risk of flap-related complications with LASIK is very low, with Intralase, the rate of flap complications are further reduced. The flap created by the laser is determined and created by your surgeon, so it is tailored to the contours of your eye.
How long does LASIK surgery take?
A: The total time in the surgery suite takes about 20 minutes. During step 1 of the procedure, creating the flap, the laser application takes about 15-20 seconds per eye. Step 2 of the procedure, applying the laser treatment, depends on your prescription. It can take from just a few seconds, to about one minute per eye. Dr. Moran will let you know the length of your specific treatment. During the laser application, he will count down the seconds, so you know how much time remains. He keeps you informed about what you can expect, every step of the way.
What is the difference between LASIK and PRK (photorefractive keratectomy)?
A: PRK vision correction is done without creating a flap. Instead, PRK starts by removing a small area of tissue on the surface of the cornea. A clear contact lens is placed on the eye after PRK surgery, to aid in comfort while healing. Dr. Moran will remove the contact lens when the cornea is healed, usually about 3 days after surgery. The recovery time for PRK is longer than LASIK. With LASIK you should be able to drive the day after surgery, while after PRK surgery, you may not see clearly enough to drive for a few days. Why do patients choose PRK? PRK is an option for patients who may not be able to have LASIK due to thinner corneas. PRK is also preferred for patients who are at risk for eye injuries, including patients who do boxing, mixed martial arts, or who are joining certain levels of the military.

What are the minimum vision requirements for driving?
So often we are asked “How well do you need to see to drive?” The vision rules may vary from state to state, so it is important to check the specific requirements for the state where your license was issued. The information below is an overview for Pennsylvania drivers. For complete, up-to-date information, please visit Pennsylvania Department of Transportation.
A visual acuity test is an eye exam that checks how well you see the details of a letter or symbol from a specific distance. The standard for normal vision is 20/20. If your vision is measured at 20/40 or 20/60, it means that your vision is worse than 20/20. With 20/40 vision, you need to be at a distance of 20 feet in order to see what someone with normal vision can see at 40 feet.
- In order to drive without corrective lenses, like glasses or contacts, you must have 20/70 or better vision during the day. Nighttime driving requires 20/40 or better vision.
- If you need corrective lenses to reach the vision requirements, you must wear them at all times while driving.sisipisi.ccsisipisi.ccsisipisi.ccsisipisi.cc
- If your vision can only be corrected to 20/60 you may be able to get a license that restricts you to drive during the day only.
- If your best vision is between 20/70 and 20/100, you may be eligible for a restricted license that would prohibit driving on freeways and highways.
- Restricted licensees may need to pass a vision test yearly.
Vision in One Eye Only
People who have only one eye, or have vision in only one eye have additional requirements. These requirements include 20/40 vision in the good eye. The vehicle must be equipped with mirrors or cameras that allow the driver to see 200 feet to the rear.
In order to drive, you must also meet field of vision requirements. Your horizontal visual field must be 120 degrees wide in order to qualify for a drivers license. Your visual field is measured by how well you see in your peripheral vision, while your eyes are focused forward.
If you drive professionally – like a school bus driver – the requirements are more stringent. The field of vision must be 160 degrees, and you must be able to identify colors used in traffic signals and signs: red, green and amber; and you must see 20/40 or better.
There is an eye condition called “Surfer’s Eye”. Can you guess how it got its name?
It’s not about the water…but If you thought it had to do with too much sun exposure, you would be right!
Long-term exposure to UV rays from the sun, as well as wind and dust, may result in growths on the surface of the eye. Surfers are particularly vulnerable, since they spend their time in the sun without sunglasses or other eye protection.
The technical term for growths on the eye caused by sun exposure are called Pinguecula and Pterygium. The condition appears on the eye’s conjuctiva (the clear covering over the white part of the eye.
Pinguecula is a yellowish, raised growth on the conjunctiva. It’s usually on the side of the eye near your nose, but can happen on the other side too. A pinguecula is an abnormality formed by protein deposits, calcium or fat. It’s like a callus on your finger or toesisipisi.ccsisipisi.ccsisipisi.ccsisipisi.cc.
Pterygium (Surfer’s Eye) is a growth of fleshy tissue (has blood vessels). It usually has a triangular shape. It can remain small or grow large enough to cover part of the cornea. When it grows into the cornea, it can interfere with your vision.
The symptoms of pinguecula and pterygium can range from mild to severe. They include:
- redness and swelling of the conjunctiva
- a yellow spot or bump that builds on the white of your eye
- dryness, itching and burning in the eye.
- sensation of something in the eye
- The best treatment is prevention…keep your eyes lubricated with artificial tears and wear sunglasses with UV protection.
- If you have the condition, lubricating eye drops will help to reduce discomfort.
- Your doctor can prescribe steroid eye drops which may reduce inflammation, redness and swelling in the eye.
- Surgical Removal: If eye drops alone don’t alleviate the symptoms, or if the growth is large enough to interfere with your vision, the growth can be removed surgically.

Do you have an astigmatism?
The word might sound scary, but an astigmatism is nothing to be afraid of! It is a common vision condition which most commonly occurs when the cornea (the clear front cover of the eye) is irregularly shaped.
If you have an astigmatism, the curve of your cornea is shaped more like a football, instead of round like a basketball. This irregular curvature causes vision to be blurry, because your eye cannot focus light to a single sharp point on the retina. Instead, light hits the retina in multiple places, so images are blurredsisipisi.ccsisipisi.ccsisipisi.ccsisipisi.cc.
You may have been born with astigmatism. You could have inherited it from your parents. It can decrease or increase over time. Astigmatism often occurs along with with nearsightedness, or farsightedness.
How is astigmatism measured?
Testing for astigmatism may may include:
- Visual acuity-When you read letters on a distance chart, you are measuring your visual acuity. The result is given in two numbers, like 20/40. The first number is the number of feet from the eye chart. The bottom number shows the smallest size line you can read. If you have 20/40 vision, you would have to be within 20 feet of the chart to see what someone with normal vision could see at 40 feet.
- Topography– This device measures the topography of the surface of the cornea. As you might guess, this measurement is important for a good fit for contact lenses.
- Refraction– You might know this as the “Better 1 or Better 2 test”. While you look through an instrument called a phoropter, we rotate through a series of lenses. Based on your answers, the power is then refined to determine the lenses for the clearest vision. This power can be determined with machines but patient input remains integral in determining vision needs.
How is Astigmatism Corrected?
A comprehensive eye exam will measure the correction or power needed for your vision, which may include a prescription to correct your astigmatism. Eyeglasses or contact lenses will help you to focus and to see more clearly.
- Eyeglasses. Astigmatism can be treated with a pair of prescription eyeglasses. The lens will have a prescription that compensates for the astigmatism. This prescription provides additional power in specific parts of the lens. The correction power lies along a specific axis.
- Contact lenses. Contact lenses may provide clearer vision and a wider field of view. A special toric soft contact lens offers astigmatism correction for many patients. This contact lens is weighted so that it maintains the correct axis when worn. Another contact lens option is a rigid gas-permeable (RGP or “hard”) contact lenses to help reshape the cornea decreasing the astigmatism.
- Laser and other refractive surgery procedures. LASIK or PRK surgery can correct astigmatism by reshaping the cornea. With LASIK using Custom-Vue Wavescan, your treatment is tailored to your eyes. Dr. Moran has great success treating patients with astigmatism.
