You go to any appointment and you hear an abundance of medical terminology that you might not understand – we’ve been there too. When you are at your eye appointment you might hear the terms nearsightedness and farsightedness. You might even be dealing with one of these conditions. But what do they both mean? First, let’s start off with nearsightedness. Nearsightedness, also known as myopia is a condition where you have trouble clearly seeing objects that are far away from you but have no issues seeing objects up close. For example, if you are dealing with myopia you generally won’t have any problems when you are using a computer or reading. People who suffer from myopia may have trouble reading road signs while driving, a white board at school, or being able to make out objects that are at a distance away from you. In most cases, people generally start experiencing blurry vision caused by nearsightedness at an early age. It was reported that 40% of the world’s population suffers from this condition and that percent will only continue to grow over the years. Next up is farsightedness. Farsightedness also known as hyperopia is the condition where people have no problem seeing things at a distance but struggle when they are trying to see things close up. Someone with this condition may have trouble reading or using a computer but will have no problem seeing objects that are further away from them. Farsightedness tends to run in families and is commonly present at birth. Luckily for people dealing with nearsightedness and farsightedness, there are many options you have to enhance your vision.

A WaveScan is a computerized device that we use to create a “fingerprint” of your vision prior to having surgery with LASIK or PRK with the AMO/VISX Star S4 IR excimer laser. Although other people may have the same refraction as you, your WaveScan is unique to you. This technology allows us to capture your refraction, including higher order aberrations, and to upload your diagnostic data to the computer that drives the laser. Because the laser has iris recognition technology (called “iris registration” or “IR”), the laser will know the difference between your right and left eye (thus eliminating the possibility of wrong site surgery) and, after locking onto your eye, will deliver a customized treatment in the exact spot where the diagnostic data were acquired.
Using the WaveScan together with our AMO/VISX Star S4 IR excimer laser allows us to offer truly customized wavefront guided LASIK and PRK, called CustomVue.

Are you ready for the total solar eclipse on August 21?If you live in the continental US, this could be your best opportunity to see such a rare phenomenon!
What Is A Solar Eclipse?
The sun is about 400 times larger than the moon, but it’s also 400 times farther away from the earth, which is why they look the same size in the sky. When they line up with the earth just right, the moon can block out the sun, resulting in a solar eclipse. Anywhere the moon’s shadow falls, we see the eclipse, but it’s only a partial eclipse unless we’re in what’s called the “path of totality.”
What makes this year’s eclipse particularly rare and special is that it is a total eclipse. The moon’s orbit isn’t 100 percent consistent. Sometimes it’s closer to the earth and appears larger, and sometimes it’s farther away and appears smaller. When it lines up with the sun while farther away, the result is an annular eclipse, where you can still see a “ring of fire” around the silhouette of the moon because it isn’t big enough to completely block the sun.
A total eclipse only happens if the moon is closer to the earth when it lines up with the sun, and the only way we can see the diamond ring effect, the sun’s corona, stars during the day, and other amazing effects is during a total eclipse.
What Damage Can The Sun Do to My Eyes?
You never want to look directly at the sun without proper protection. Even during an eclipse when the sun is 99% covered by the moon, its rays are still strong enough to cause serious eye damage or blindness. The ultraviolet (UV) rays combined with the heat emitted by the sun can cause a sunburn of the eye, or even more permanent damage called solar retinopathy. Symptoms may include blurred vision, red eyes, a foreign body sensation or gritty feeling in the eyes, extreme sensitivity to light, and excessive tearing. If you believe you accidentally damaged your eyes due to the solar eclipse, schedule an appointment with an eye doctor.
How to Safely View the Solar EclipseAverage sunglasses are not suitable to protect your eyes while viewing the solar eclipse. There are a few ways to view the solar eclipse without damaging your eyes:
Patients who have been wearing contact lenses have made the choice to minimize their dependence on eyeglasses, but still have many of the inconvenient aspects of contact lens and care to contend with. For contact lens wearers, the decision to have LASIK represents the desire to experience a lifestyle and convenience with independence and freedom from the hassle of BOTH glasses and contacts. But, how does satisfaction with LASIK actually compare with contact lens wear? Researchers reporting in the journal Ophthalmology assessed patient satisfaction and perceived outcomes of 1800 patients split into two groups-one continuing to wear contact lenses and the other having LASIK, through annual surveys administered over a 3-year period. Most contact lens users had worn them successfully ≥5 years. The proportion expressing strong satisfaction with their current vision correction method decreased from 63% at baseline to 54% at year 3 in the contact lens control group, whereas 88% of former contact lens wearers and 77% of former glasses wearers were strongly satisfied with LASIK at year 3. Patients 40 years of age or younger when they had LASIK were somewhat more likely to be strongly satisfied than older patients. LASIK significantly reduced difficulties with night driving and nighttime visual disturbances among former contact lens users and former glasses users. The proportion with dry eye symptoms at 1, 2, or 3 years after LASIK was not significantly increased relative to baseline contact lens wear but was significantly increased relative to baseline glasses use, consistent with many glasses users having tried and abandoned contact lenses because of latent dry eye problems. Compared with continued contact lens wear, LASIK significantly reduced the self-reported rates of eye infections, ulcers, and abrasions each year.
The overall conclusions then were that compared with contact lens wear, current LASIK technology improved ease of night driving, did not significantly increase dry eye symptoms, and resulted in higher levels of satisfaction at 1, 2, and 3 years follow-up.
