Gainesville Eye Physicians and Optical now uses the LenSx® Laser System to produce amazing results and quicker recovery times for cataract patients in North Central Florida. We’re the first practice in the area to offer this state-of-the-art technology.

LenSx® delivers completely bladeless and pain-free cataract surgeries with significantly more accuracy than manual procedures. Traditional surgical blades are replaced by a computer-guided laser, producing more precise incisions. The system also captures high-resolution images of the eye and provides detailed measurements and other data Dr. Snodgrass uses to plan and perform the cataract surgery. 

For patients, the LenSx® Laser System means better vision and faster healing. The laser uses half the ultrasonic energy once needed to remove cataracts. That translates to less risk and inflammation. In most cases, the patient’s vision improves almost immediately after surgery.

Cataracts are cloudy areas in the lens of the eye that prevent light from passing, making the patient’s vision similar to looking through frosted glass. There are several warning signs for cataracts that should prompt individuals to get an eye exam including cloudy vision and lens discoloration.

Surgery is the only way a cataract can be removed. The surgeon cuts an incision in the eye, removes the natural cloudy lens and replaces it with a clear artificial lens implant.

Dr. Snodgrass, who has performed more than 20,000 such surgeries, uses this remarkable new tool to make more precise incisions than even the steadiest, most experienced hand could hope to accomplish. With LenSx®, it’s exactly right every time.

8 Foods that Promote Eye Health

by dwasylow 5 March 2014 06:06 AM

Mom was right, eating carrots is good for your eyesight, but they’re certainly not the only food that promotes good eye health. The eyes are complex organs that require a mix of the right nutrients to perform their best and last a lifetime. Regularly eating foods from the list below will put you on the right path to vision-sustaining nutrition.

Carrots

Carrots owe their orange coloring to a type of vitamin A called Beta-carotene. This antioxidant helps the retina and other parts of the eye work properly. Beta-carotene may also reduce your risks for cataracts and macular degeneration

Leafy Greens

Spinach, kale and collard greens are great sources for the antioxidants lutein and zeaxanthin. These substances increase pigment density in the macular tissue of the retina and absorb up to 90% percent of blue light, shielding the tissue from damage.

Fatty Fish

Don’t worry, eating “fatty fish” won’t necessarily add pounds. It will, however, provide a healthy dose of omega-3 fatty acids. Fish including tuna, salmon, mackerel, anchovies and trout are rich in docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) which help prevent dry eye syndrome.

Citrus Fruits and Berries

Found in high concentrations in citrus fruits and most berries, vitamin C produces multiple benefits for eye health. Besides reducing risks for age-related macular degeneration and cataracts, vitamin C also helps keep ocular blood vessels healthy. Our bodies don’t naturally produce vitamin C, so dietary intake is essential.

Almonds and Peanuts

Almonds and peanuts are filled with vitamin E, believed to fight off damage from free-radicals. Research also shows this nutrient plays a key role in slowing macular degeneration. Just a couple handfuls provide enough vitamin E for your whole day.

Kidney Beans

Kidney beans are an excellent source of zinc, a mineral that helps transport the vitamin A from other foods (like carrots and leafy greens) from the kidneys to the retinas. Zinc also plays a role in improving night vision.

Apricots

Apricots are eye health dynamos. They contain just about every nutrient a healthy eye needs, from Beta-carotene and vitamin C to lutein and zeaxanthin. Apricots also provide significant levels of calcium, potassium and iron.

Ostrich

If you’ve never tried ostrich, here’s a great excuse to give it a shot. Ostrich is rich in zinc, which promotes healthy functioning for several enzymes that benefit the eyes. For those with less exotic tastes, you can get similar levels of zinc from turkey.

Eye Allergies – Don’t Rub Your Eyes!

by dwasylow 21 January 2014 03:01 AM

Nobody likes allergies. Depending on your sensitivity, they can cause discomfort and watering, limit vision and generally disrupt your day. If you wear contact lenses, allergies can be especially troublesome. Eye allergies are some of the most frustrating allergies to have.

Eye allergies are usually accompanied by other allergies such as eczema and hay fever. Environmental conditions can also cause allergic reactions or irritation. If you find yourself with red, puffy eyes, it’s likely you’re experiencing an allergic reaction of the eye. Here are other symptoms:

  • Itchy Eyes
  • Blurred Vision
  • Burning sensation
  • Eyelid swelling
  • Tearing
  • Light sensitivity

When experiencing any of these symptoms, the first thing to remember is DON’T RUB YOUR EYES. You might have the urge to do so for temporary relief, but you’re just making the situation worse. Allergic reactions in the eyes occur when mast cells in the eye release histamines in response to allergy triggers. These histamines cause the itchy redness and puffiness most associated with eye allergies. When you rub your eyes, you further irritate the mast cells, causing them to release more histamines; resulting in more discomfort.

The best way to relieve eye allergy discomfort is to apply a cold compress or wet washcloth over your eyes, which will help stop the discomfort temporarily. In addition, if you have an antihistamine, like Benadryl, you should take one. Your eye doctor can recommend an over the counter allergy drop, or for more severe symptoms, he may need to prescribe a mild anti-inflammatory drop.

Finally, avoid allergen-rich environments, keep your hands clean and avoid touching your eyes. Even the tiniest allergen can cause discomfort if you’re not careful.

How to Find the Right Contact Lenses

by dwasylow 16 January 2014 05:47 AM

There are basically two non-surgical options for correcting your vision. Either, wear glasses or try contacts. Even with thousands of choices in designer eyeglass frames, some people still prefer the look and benefits of wearing contacts.

Benefits of Contacts

  • Less likely to be obstructed by accumulated debris or smudges since they rest directly on your eyes and are cleared each time you blink
  • Greater field of view
  • Less likely to interfere with performance during sports and games
  • Resist fogging up due to extreme temperature changes

What do you need to do in order to wear contacts?

First, you need to schedule an appointment with your eye doctor for a routine eye exam and contact lens fitting. If you haven’t had your routine eye exam yet, we recommend you do so soon. It’s one of the first things most people should have on their lists for the New Year.

Since contacts lie directly on the eye, your eye doctor must measure your eye in order to prescribe the correct contact lenses. This is a quick and painless procedure.

Following these exams, the doctor will sit down with you and go over the basics of wearing and cleaning your contact lenses. This is important. If you neglect proper cleaning or otherwise fail to take care of your contacts, you could end up with complications.

There are different methods for putting in your contacts; it all depends on your muscle reactions and how well you can keep your eye open when inserting contact lenses. This fun video below gives a general guide on how to put in and take out your contacts:

https://www.youtube.com/watch?v=pNcQf-aDNP0

It’s important to use a good contact solution to clean your contacts. Your eye doctor can recommend a solution that matches the type of contacts you wear.

The doctor will give you a pair of trial contact lenses to test out over the course of a week so you can get a feel for them. After that week, you’ll come back and he’ll check your eyes for any irritation or damage. If he finds no complications and you’re comfortable wearing contacts; he will ask you if you want one-day, weekly, monthly or continuous wear contacts.

The most comfortable contacts are often the one-day disposables, since you have a fresh pair each day, but they also tend to be more expensive. Ask your eye doctor what he recommends and you’re sure to enjoy a clearer outlook on the world.

20/20 Vision is a Requirement for Some Careers

by dwasylow 13 January 2014 06:33 AM

If your eyesight isn’t up to snuff, it’s likely you have some form of corrective lenses. However, for some careers, contact lenses or glasses may not be practical or even acceptable. Photographers, for example, find glasses to be intrusive as they are unable to hold the camera right up to their eye. But, these high danger and high-risk jobs actually require 20/20 vision in order to get the position.

Firefighters

Firefighters need to be able to spot victims in burning buildings instantly, as well as spot dangers from fire damage when arriving at the scene of a fire, making fantastic eyesight a must. In addition, you must be able to quickly scan fire codes on buildings or structures in order to understand what method should be used to resolve the situation.

The exposure to smoke and other debris can make contact lenses dangerous, and rule them out as options.

Police Officers

Police need great eye sight

Having bad eye sight as a police officer is going to do more harm than good in the long run. If the officer is unable to identify a criminal within a crowd or properly judge a situation quickly due to vision that isn’t up to par, he may be putting himself and others at risk. Ideally, officers should have 20/20 vision in order to help them in the event of danger, to aid in criminal investigations or to be a witness in court.

Life Guards

Sunglasses a valuable tool for lifeguards

Often seen at the local pool or at the beach, lifeguards can be found seated on high tower chairs or in high tower posts overlooking the area. As they are inherently far away from any situation, it is imperative they have 20/20 vision so they can spot people who are in danger and can react as quickly as possible.

First Responders / Paramedics

First responders only have moments to assess a situation. If they don’t notice everything within a few seconds of arriving on the scene, the life of the person they came to rescue could be at risk. Needless to say, 20/20 eyesight is a must for paramedics to quickly respond, identify injuries or read medical alert bracelets.

If you find yourself with subpar vision and traveling down one of these career paths, you may need to consider laser eye surgery. And while 20/20 eyesight is a must for these careers, it remains important to have healthy vision for everyone else. Our eyes are windows to our world; if you can’t see clearly, you’ll miss out on the little things. If you haven’t already, it’s best to schedule your yearly eye exam as soon as possible.

Choosing the Best Sunglasses for Your Outdoor Activity

by dwasylow 10 January 2014 07:12 AM

Spending time outdoors on a beautiful and sunny Gainesville day can be enjoyable, but without sunglasses it can be dangerous to your eye health. The right sunglasses can protect your eyes, and help reduce glare and brightness, both of which can cause discomfort. 

While most sunglasses are strong enough to protect your eyes, there are many options and people sometimes have a hard time picking the right ones. Here are some tips to help you choose the right pair of sunglasses for your favorite outdoor activity.

If you enjoy fishing, you want to make sure to protect your eyes from hooks and sinkers. Fishing sunglasses should be wraparound if possible and the lenses made of sturdy polycarbonate or trivex.

Fishing is the most common outdoor activity that relates to eye injuries. About 38% of fishing eye injuries involve getting a hook caught in the eye – 44% come from getting hit in the eye by a sinker or lure.

Regular sunglasses do not provide enough protection. Instead, try to find a pair of sunglasses specifically designed for fishing. These lenses usually have a brown tint and provide better coverage for your eyes.

If you are cycling, kayaking or hiking, protecting your eyes from glare and ultraviolet rays is the most important thing you’ll want to take into consideration.

Always choose sunglasses with 100% UV protection. While a pair of glasses may look fashionable, it’s likely that they do little protect to your eyes from the sun. So it may be best to choose function over fashion.

Lens colors make a difference

Gray or green colored lenses are a good choice for runners, cyclists and golfers. These lenses help your eyes see true color, and allow you to better appreciate your surroundings, the way they were meant to be seen.

Amber or brown lenses are great for cloudy days. Both colors enhance the contrast in your vision. Brown lenses are wonderful for boating, fishing and skiing. Amber lenses, though they distort colors, reduce eye strain, and are thus better suited for pilots, hunters, skiers and others engaged in all-day outdoor activities.

Yellow lenses are effective in low-light environments, especially on those partly cloudy days, when the sun isn't strong but the day is still bright. Yellow lenses are also a great choice for skiing.

Use sunglasses with red lenses if you need an optimal contrast between objects and green or blue backgrounds. Red lenses are useful when sailing, boating, hiking and hunting.

Should I consider polarization?

Most people may not be familiar with polarization. It allows sunglass lenses to absorb light from angles, and is optimal for blocking glare. Definitely pay attention to the availability of a polarized filter when purchasing the right pair of sunglasses.

Try them on before you buy

Choose a pair of glasses that sit high on your nose. This will allow you to easily keep the lenses close to your eyes, and block light from the sides.

The sunglasses should fit your face well. If they have a nose pad, make sure the pad fits your nose properly. If they don’t have one, the sunglasses should fit the bridge of your nose snugly, but not tightly.

The most important thing is comfort, so keep trying them on until you find the pair that is just right.

If you are unsure which sunglasses may be right for you, come on in! Our optical department will be able to assist you and find the pair that suits all of your needs.

Start the New Year off Right with Your Yearly Eye Exam

by dwasylow 19 December 2013 08:11 AM

With January 1st fast approaching, many of us think about New Year’s resolutions. Typical ones like resolving to lose five-to-10 pounds, read more or travel the country are all great additions to your resolutions list. This year, however, we have another resolution you should consider…making an appointment for your annual eye exam.

Your eyes are important and fragile parts of your body. If you don’t take good care of them, you’ll have a harder time seeing the world. It’s important to have a comprehensive eye exam every year to keep your eyes in good health. In addition, this is a chance for your eye doctor to see if you’re at risk for developing any eye diseases or vision degradation. It’s best to maintain and prevent any diseases; if found, before they get out of hand. Routine yearly eye exams help achieve this and it should be a part of everyone’s New Year’s resolution.

What Is the Doctor Examining?                       

Your eye doctor will do an initial sight measurement to determine your overall visual health. This primarily looks at “refractive error” which is classified into three vision impairments:

  • Myopic or nearsightedness – difficulty seeing objects in the distance.
  • Hyperopia or farsightedness – difficult seeing objects up close.
  • Astigmatism – Blurred vision due to irregular formation of your eye’s lens or cornea.

Usually, these 3 vision impairments are corrected by prescription glasses or contacts. While having those items will give you a clear picture, it’s recommended to maintain your yearly exams to ensure your vision isn’t getting worse.

Added to the sight measurement, eye physicians test if you’re at risk for certain eye diseases. Most of the time, catching these diseases early and treating them right away will alleviate any risk of vision loss.

Don’t put of this exam until it’s too late. It only takes a few minutes and you’ll be out the door happy you got your eyes examined.

The Value of Seeing a Licensed Optician

by dwasylow 16 December 2013 12:05 PM

At Gainesville Eye Physicians and Optical we are committed to delivering the highest quality of healthcare. That’s why we hire licensed opticians to treat patients in our optical department. Not every optical shop can claim that. In fact, most retail eyeglass outlets don’t employ licensed opticians. So, why is that important for your eye health?

Let’s begin with a definition. An optician is someone who interprets the prescriptions created by ophthalmologists or optometrists to produce contact lenses or eyeglasses. They often use a series of tests and technologies to determine how a patient can best benefit from the lenses and frames they select. These evaluations take into consideration both vision needs and lifestyle preferences.

Accurately translating the physician’s prescription into a set of lenses that address your vision needs is, of course, a critical step. It’s not uncommon for a patient to complain that an eye doctor inaccurately diagnosed their condition, when the breakdown actually occurred in the creation of the lenses.

Becoming a licensed optician requires a great deal of education, apprenticeship and testing. The State of Florida requires an optician to apprentice for 6250 hours before they can take the necessary tests to be licensed, some of these hours can be accounted for through a formal post-secondary educational program. Following this training, they take multiple board examinations to ensure their expertise.

Many retail optical shops put responsibility for your lenses in the hands of lesser-trained individuals. In fact, they may have no formal training beyond the company’s in-house instruction. This can result in glasses that fail to correct your vision problems and may even make them worse.

Gainesville Eye Physicians and Optical is blessed to have two of the best trained and best liked opticians in all of Florida, Mindy Tillman and Fagan Arouh, and they are both licensed. That means their education and skills surpass many others in our area.

When selecting someone to fill your eyeglass or contact lens prescription, remember to ask if he or she is a licensed optician. At Gainesville Eye Physicians and Optical, the answer will be yes.

Best Practices for Eye Safety in the Workplace:

by dwasylow 26 November 2013 10:26 AM

It’s an unfortunate fact: work-related eye injuries happen. Can these injuries be avoided? Safety experts and eye doctors around the country say, yes. In fact, they believe 90 percent of eye injuries in the workplace could have been prevented with proper protection and safety habits.

It’s not surprising that many injuries come from industrial environments. On the job, our eyes are vulnerable to various hazards - projectiles, open chemicals and radiation in the form of UV and infrared light, just to name a few. High-risk jobs include:

  • Manufacturing
  • Carpentry
  • Electrical work
  • Auto repair
  • Plumbing
  • Welding
  • Maintenance
  • Mining

If you find yourself in one of these careers you’ll want to ask your employer to assess the work environment for eye safety. The employer can remove or reduce eye hazards where possible, and provide appropriate safety eyewear as well as require workers to use it.

You need to make sure you are using proper glasses, goggles, face shields or helmets specifically designed for your task. It’s the easiest and most effective way to keep your eyes safe.

If needed, your ophthalmologist or eyecare provider can assist your employer in determining potential eye hazards and evaluating the need for eye protection.

Do you work in an office job, and believe your eyes are pretty safe from hazards? Not so fast.

Office jobs where at least six hours per day is spent looking at some form of digital screen put eyes at risk as well. We subject ourselves to what is called digital eye strain.

We’re all familiar with the symptoms of digital eye strain:

  • Eye redness or irritation
  • Blurred vision
  • Dry eyes
  • General fatigue
  • Back pain
  • Neck pain
  • Headaches

Fortunately these too can be avoided, or at least lessened. Increasing the font size on your screen, setting up an “eye-gonomically” friendly work station or even using computer eyewear can all dramatically reduce the effects of digital eye strain.

A report from The Vision Council provides tips for preventing digital eye strain by adjusting both internal and external factors while at the workplace.

External Factors:

  • Reduce glare – Adjust the brightness of your screen to match the appropriate light level. Wiping down your screen with a clean cloth every so often can also help reduce glare.
  • Make sure lights around you are dim – If your screen isn’t competing for brightness with overhead or surrounding lights, your eyes will be less strained. 
  • Distance is healthy – Keep enough space between your eyes and the screen. For best practice, you should be far enough away where you can extend your arm and comfortably high-five the screen with your palm; if you can’t fully extend your arm, you’re too close to the monitor.

Internal Factors:

  • Blink, blink, blink – In addition to keeping your eyes moist throughout the day – staring at a screen can really dry them out – blinking helps your eyes refocus every so often.
  • 20-20-20 – It’s recommended you take a 20 second break every 20 minutes, and during that break look at something 20 feet away. This will give your eyes a nice rest every so often. 
  • Consider special eyewear – First and foremost, check to see if your prescription is up to date for corrective lenses. This can help alleviate a lot of strain. There are also glasses specifically designed to reduce glare from digital screens – to achieve this special tints and coatings are applied directly to the lenses. They’re available in both prescription and non-prescription lenses.

No matter where we work, eye safety should be in the back of our minds. Eyes are windows to our world, and we should do everything we can to protect and keep them healthy.

Warning Signs of Cataracts

by dwasylow 12 November 2013 04:00 AM

Like so many diseases, few people know the warning signs of cataracts, or what to do about them. Cataracts are cloudy areas in the lens of the eye. They prevent light from passing through the lens (or lenses if both eyes are affected) and, as they become progressively worse, can make the patient’s vision similar to looking through frosted glass.

Below are symptoms that may indicate you are developing cataracts.

Cloudy or blurred vision

Cataracts start off small, so only a minimal area of your vision is initially impacted. You may occasionally look a specific direction and notice a blurred spot. It’s fairly common for patients to brush off these early signs. That clouded area will eventually grow, however, and overtake your full vision.

Lens discoloration

Cataracts cause a discoloration of the lens that result in patients beginning to notice that colors aren’t as bright as they once were. It’s like looking at life through a yellow or brownish film. Blues and purples are especially hard for the patient to distinguish as cataracts progress.

Light sensitivity, glare and halos

Cataracts can cause sunlight and lamps to seem uncomfortably bright. They can also cause patients to see glare around these light sources. When driving at night, a person developing cataracts will often see halos around the headlights of oncoming traffic.

Double vision

Double vision in one eye is common in cataract patients. Oddly enough, this may improve as the cataract grows larger and covers a larger portion of the lens’s surface. This is a dangerous symptom because it can throw off a person’s balance, so it should be checked out immediately.

Temporarily improved near vision

As strange as it may sound, some farsighted patients experience short-term vision improvement due to the impact cataracts have on the shape of the lens. They may even be able to read without the assistance of glasses for a short time. The improvement is only temporary, however.

Changes in vision

As pointed out above, cataracts can dramatically change your vision as they progress. As a result, patients developing cataracts frequently need changes to their eyewear prescriptions. A trained optometrist or ophthalmologist should be able to quickly recognize this issue in a patient.          

Presence of the symptoms above – individually or in combination – does not necessarily mean a patient has cataracts. Some symptoms can result from other eye diseases. Contact Gainesville Eye Physicians and Optical for a comprehensive exam, diagnosis and treatment plan.
