Understanding LASIK Incisions

Laser vision correction eye surgery has brought lens-free vision to literally millions of people over the years. Technology continues to improve this medical procedure, making the outcomes more precise than ever before.

So why hasn’t everyone jumped on the laser vision correction bandwagon? Fear is one factor that keeps some people away. Specifically, fear of the laser vision correction incision. Let’s face it: our eyes are sensitive, and the thought of having a procedure that involves cutting the cornea can be scary. When you have detailed information about the procedure, you can make an informed decision about whether or not to pursue laser vision correction.

Type of LASIK Incisions

In laser vision correction surgery, the surgeon makes a thin flap in the cornea via one of two methods:

• Mechanical tool called a Microkeratome. This is an oscillating, hand-held blade that is controlled by the surgeon. 
• Femtosecond laser also referred to as “bladeless” LASIK. Pre-calculated computer software guides the laser beam to cut the flap at a precise diameter and depth.

The corneal flap is folded back to allow the surgeon to reshape the cornea and correct nearsightedness, farsightedness and astigmatism issues. When the refractive error work is completed, the surgeon folds the corneal flap back down, where it heals itself. The whole process only takes minutes per eye! And most patients are already experiencing improved vision when they leave the office.

The truth of the matter is that laser vision correction surgery is quite safe when it is performed by an experienced laser vision correction surgeon. The Food and Drug Administration has approved nearly 30 lasers; lasers they have deemed to be safe and effective for laser vision correction surgery. There have also been advances in the microkeratome technology that have increased the effectiveness of the hand-held blade method.

Women – More Susceptible to Vision Problems than Men

According to Prevent Blindness America, “Every year, more women than men are diagnosed with eye diseases and conditions such as cataracts, dry eye, Fuchs’ dystrophy, glaucoma, macular degeneration, diabetic retinopathy and Sjögren’s syndrome.  The “Vision Problems in the U.S.” study from Prevent Blindness America (PBA) and the National Eye Institute (NEI) shows that of the more than 3.6 million Americans age 40 and older who suffer from visual impairment, including blindness, 2.3 million are women” (Women Must Take Steps to Avoid Vision Loss, March 27, 2012).

Hereditary diseases aside, these problems are often caused by hormones, or the fluctuations in hormones like pregnancy or menopause. Sometimes they can even be triggered by birth control, which is a hormone regulating medication. Even keeping your eye makeup for too long can cause problems with your eyes.

At Pacific Eye Specialists, we recommend to our female patients that they pay close attention to their eyesight while pregnant, when changing prescription pills or going on new medication, and to switch out their makeup every six months to a year. If you feel that your glasses or contacts are not helping as much as they used to, make sure to have an eye exam. Mention to your doctor any new prescription changes so that he may accurately diagnose the underlying issue.

Your eyes are how you see the world. Keep them in great health.

Eye Strain Issues

If you work in front of a computer, you have probably experienced eye strain. Here is a great video with a few tips to help keep your eyes in top performance!

Super Human Vision

Superhero powers are only a thing of comic books. No one person has super powers.

Or do they?

Scientists have begun to uncover an ability found in only about 12% of women – the ability to see more colors in the color spectrum than originally thought possible. While studies are still being performed to test this new vision ability, the thought that our world holds more color than most can see is quite intriguing.

The eyes are a very powerful thing.

Laser Vision Correction vs PRK

Refractive errors occur when the cornea of your eye, or the front part of your eye, is misshaped. These refractive errors produce nearsightedness, farsightedness, or astigmatism. Laser vision correction is the procedure through which a laser is used to reshape the cornea of the eye, in order to achieve better vision.
While the actual correction of the cornea is completed with a laser, the steps leading up to this correction, and subsequently the healing after, will differ depending on the specific procedure the surgeon chooses for the patients’ eyes. The two main procedures most commonly used are LASIK (Laser-Assisted Sin-Situ-Keratomileusis) or PRK (Photorefractive Keratectomy).
LASIK and PRK
Most people have heard of laser vision correction; however, in some cases, laser vision correction isn’t the best procedure for them. This can be due to a multitude of reasons, but most often if their cornea is too thin, laser vision correction will not be advised. This is why visiting an ophthalmologist that performs more than just laser vision correction is so important. Other procedures, such as PRK, can be recommended and performed to achieve the same, and sometimes even better, results.
The main difference between LASIK and PRK comes during the first step of the process – creating the corneal flap. During laser vision correction, the surgeon creates flap within the first few layers of the outer surface of the cornea, so that the laser can reach the area that needs to be corrected. This can be done with a microkeratome (a mechanical oscillating blade), or during bladeless laser vision correction, it can be done with a second laser that separates the outer layer of the cornea. After the primary laser is applied to correct the refractive error, this flap is folded back into place where it bonds readily.
PRK, which is usually performed on patients with thin corneas, removes the surface layer of cells on the cornea. This is why it is often referred to as a surface treatment. After treatment, the body will regenerate new cells to replace the cells removed through a relatively quick healing process. The results of PRK are equal to that of laser vision correction though the healing times are slightly longer.
Visiting a Qualified Ophthalmologist
Performing laser vision correction on a patient that is better suited for a procedure like PRK will increase the likelihood of potential risks, such as poor night vision or less than optimal results. To decrease these risks, visit a board-certified ophthalmologist who is skilled at multiple vision correction procedures. This will ensure you the best possible chances to achieve the vision results you are seeking.

Happy Thanksgiving!

Happy Thanksgiving from Pacific Eye Specialists. We hope you have a wonderful and safe Turkey Day!

Why Your Eye Surgeon Needs to be Local

Corporate medicine has its benefits and its downfalls. In regards to the refractive surgery field, there are more downfalls to a corporate practice than there are benefits. But first, let’s take a look at what the difference is between a local ophthalmology practice and a corporate one.

Local Ophthalmology Practice

A local ophthalmology practice is one that has one or just a few locations, all found within the same state, the same geographical region. The doctors and staff are all from the area as well.

Local practices are usually owned by the doctor or surgeon, or a small group of doctors or surgeons. They are responsible for all of the decisions regarding staffing, technology, services offered, and everything else that is included with their particular practice.

Corporate-Owned Ophthalmology Practice

A corporate-owned ophthalmology practice is one that has multiple locations, usually nationwide. These practices are run through a company, which is run by a board of directors. They often only offer one or two services, usually just LASIK, and maybe PRK. They employ thousands of doctors and traditionally these doctors work at multiple locations. They travel to different locations, perform surgery and then travel to another location. Some doctors even travel to different states just to perform surgeries.

All decisions are made by a board of directors, not the staff or doctors working in each particular location.

The Difference

So what’s the difference? Why should you choose one location over the other?

Doctor Availability

Perhaps the biggest factor in why you should really know the difference between the two types of ophthalmology practices is doctor availability. In a locally owned practice, the doctor lives in or near town. S/he works at the practice full-time and performs consultations, the planning of treatment, the surgery, and the post-operative follow-up exams on each patient that comes through the door. They have a relationship with their patients, and they are most likely there for anything the patient may need.

In a corporate practice, the doctor sees patients at multiple locations. S/he will fly in, review the chart and work-up of the patient without even meeting or personally examining the patient, perform the surgery, and then fly off. This means that the surgeon that performs your particular surgery is not available for pre-surgery exams, follow-up, or even during emergency-related issues that may have resulted from your surgery. They usually have an optometrist perform these tasks. An optometrist, while a perfectly capable doctor, is not trained in the actual performance of the surgery. If a complication arises that the optometrist is not qualified to respond to, where are you going to go? Who’s going to help?

Sometimes an optometrist refers a patient for laser vision correction When this happens, the laser vision correction surgeon will perform the surgery and then refer you back to your optometrist for follow-up exams. This works well when you are referred to a local practice, so that your surgeon will still be available for any emergency issues that may arise.

So which would you prefer – a surgeon operating on your eyes, someone you’ve never met, who’s never actually seen your eyes and who won’t be around if you have an emergency? Or would you rather have someone who is local, available throughout the week, and who takes it as a personal responsibility to care for you and your eyesight?

Check back in next week when we continue this topic and discuss The Right Procedure for Your Eyes.

Putting in Your Contacts with Your Feet?

We don't often write about other laser vision correction practices, but this story highlights one practice doing what it knows to help others in the community, specifically Jessica Cox of Overland Park, KS.

Jessica Cox does not have any arms and currently does everything with her feet. This includes putting in her contacts every morning!

Now, through the gift of laser vision correction, Jessica will be able to take that routine out of her life. We applaud Dr. Daniel Durrie for helping this young lady and giving her one less challenge in her life.

The Cost of Vision Correction

Often one of the biggest reasons lens wearers hesitate to have their vision corrected is the cost. They aren’t sure how much it may cost them, if they will need to pay for multiple surgeries, if they will be able to really stop wearing lenses, and if continuing the on-going cost of lenses would just be easier.

We’d like to take a moment to educate you on a few of these points, but first, the most important decision you must make is to visit a reputable surgeon. In order to get the care and results you are expecting, you shouldn’t just trust your eyes to ANY vision correction surgeon. There are thorough surgeons and there are “other” surgeons. A thorough surgeon is an ophthalmologist that is reputable in the community, trusted by multiple patients and staff, will ensure you are an excellent candidate for vision correction (and offers other procedures if you are not), and has a low enhancement rate (the rate at which a doctor needs to enhance the original results in order to get the patient to their visual expectations).  An excellent enhancement rate is less than 10%.

Multiple Surgeries

Often patients have the misconception that to have excellent eyesight, they will need multiple LASIK surgeries. This is not true.

Some surgeons perform multiple surgeries on one patient because they were not accurate the first time, they are new to performing eye surgery, or they didn’t take accurate measurements prior to performing surgery.

As we said before, an expert surgeon will have a less than 10% enhancement rate. There are very few cases where they may need to enhance the original results, but it is mostly due to patient error in after-care or an agreed-upon course of treatment prior to surgery. These enhancements should be covered in the original cost of surgery and should NOT be a whole new surgery charge.

Stop Paying For and Wearing Lenses

This is a concern for almost every patient. After all, why would anyone in their right mind agree to eye surgery if they have to continue wearing lenses?

If you are a good candidate for the procedure and you have chosen a reputable surgeon, then you should be able to have many, many years of lens-free vision. How many years depends on how old you are at the time of surgery. Our eyes age along with us and there will be age-related issues, like Presbyopia, that require glasses for reading. Presbyopia occurs in the lens of your eye and not in the cornea (where vision issues like nearsightedness, farsightedness, and astigmatism occur). LASIK or other vision correction procedures correct the cornea and the younger you are when you have the procedure, the longer you have to enjoy lens-free vision.

Lenses or LASIK – Which is Easier?

Ultimately, this decision is going to be up to you. LASIK and other vision correction procedures are a one-time cost. We offer payment plans that will help you break down the cost of the surgery to an affordable range, and we may even be able to offer you no-interest or 0% for up to 24 months. If you chose that option, after 24 months (or two years), you will be free of the cost of lenses, contacts, or vision correction payments!

If you have a flexible spending account, it's even easier than that! Give us a call and we'll explain the details.

Or you can continue to make payments for lenses, replacement lenses, contacts, replacement contacts, cleaning solution, travel cases, travel solutions, etc. for the next 10, 15, 20, 25+ years.

The choice is yours.

Payment Plans

We are here to answer any questions you may have about payment plans and how to fit LASIK into your budget. Please feel free to give us a call at 415.921.7555 (Pacific Heights) or 650.755.6900 (Daly City) – there is no need to set up an appointment.

Why Parents Should Consider LASIK

So many of our patients that have young ones at home tell us about how happy they are that they can finally see without glasses and contacts. Their excitement usually comes from the same place – freedom to enjoy their kids without concerns of glasses and/or contacts.

It’s easy to imagine a child playing with glasses or accidentally poking a parent in the eye and a contact falls out. However, there is another underlying issue that is a huge concern when you need lenses to see: Safety.

When a child wakes up screaming in the middle of the night, do you have to stumble to find your glasses first? Do you have to blunder down the hallway half-blind because you don’t have time to put in your contacts? Or do you have to wake up your significant other to handle the issue because you simply cannot see?

It’s time to put an end to your worries. We want to help you obtain your vision goals so that you have one less thing to worry about. Come in to see us for a no-obligation consultation. We can discuss your concerns and talk about how we can help you achieve your vision goals. Give us a call today at 415.921.7555 (Pacific Heights) or 650.755.6900 (Daly City). 

Your Eyes Know

Losing sleep can affect your body in many different ways, especially your eyes. If you wake in the morning to an extreme burning sensation in your eyes, one you don't feel again throughout the day, it could be that your body needs more sleep.

The gland that produces tears needs rest, just like the rest of your body. It can even shut down on its own, which means your eyes will become dry if you're still awake.

Take care of your eyesight - make sure to get plenty of rest. To read more about this painful problem, click here.

What to Do with a Flex Spending Account

Did you know you can achieve excellent vision and use your Flexible Spending Account (FSA) to pay for it?

It's true! Our laser vision correction procedures, such as LASIK, can be paid for by using an FSA. Stop using your FSA to pay for glasses, contacts, solutions, etc. Use it to pay for great vision this year and have the money next year to pay for your really important medical expenses.

Don't forget - most FSA's are "use it or lose it" which means if you don't use the money by the end of the year, it's gone!

Eye Floaters and Flashes

Did you know that floaters and flashes that you experience in your eyesight are real?

Did you also know that they are really serious?

We all experience it one time or another. If you look directly into a light and then look away, you might see black spots in your vision for a few seconds. Experiencing floaters and flashes can sometimes be like that. You see spots that you know aren’t really there, but they are in your line of vision. Or you may see flashes of light off to the side of your vision, but there is no one taking your picture or shining a flash light at you.

Eye floaters and flashes can be the result of trauma to the eye. If you have ever been hit in the eye or have something poke you, you may notice these symptoms for a few minutes. For more serious injuries, the floaters and flashes may not go away.

You should see your ophthalmologist as soon as possible if:

• One new, large floater or "showers" of floaters appear suddenly
• You see sudden flashes of light
• You notice other symptoms, such as the loss of side vision

Your eye is filled with vitreous gel, and as you age, this gel can thicken or shrink. This may cause floaters within your eye. If the vitreous gel rubs against your retina or causes a tear in your retina, you may notice flashes.

It’s important not to ignore these symptoms. There is usually pain associated with a torn retina, but even if you do not experience pain, you should still call right away to have your vision checked.

Early treatment is the key to preserving your vision.

Fears and Misconceptions of Vision Correction – Losing Your Vision

Glasses and contacts have their benefits – mainly helping people with refractive errors see clearly. Since the late 90’s, lasers have been used to correct these refractive errors in very safe and effective ways. Procedures such as LASIK and PRK have been providing patients with clear vision for over 15 years now. However, many people continue to put up with the inconveniences of glasses and contacts because they have fears or misconceptions about laser vision correction, like LASIK.

One of the most common fears of laser vision correction is losing vision as a result of the procedure. This fear comes from not understanding how your eye works and how specifically laser vision correction works.

How LASIK Works

There are three main parts to the human eye: the cornea, the lens, and the retina. In normal vision, the cornea refracts (bends) light so it can be directed correctly through the lens and onto the retina. The retina works as a transmitter to transfer the message to your brain, where it processes the message to tell you what you are looking at. Refractive errors – nearsightedness, farsightedness, astigmatism – are caused by the cornea being slightly misshapen. LASIK utilizes cool lasers to reshape the curve of the cornea so you can have normal, clear, vision.

Prior to surgery, your surgeon maps out your specific eye and plans out exactly how to correct your vision. Your surgeon will then programs this plan into the laser, ensuring that the correct amount of your cornea is altered.

There are risks associated with laser vision correction, mainly dry eye. It is essential to ensure that you are an excellent candidate prior to receiving treatment, to give you the best results possible.

Officially there is no reported case of a patient losing their eyesight from LASIK.

To find out more about LASIK, including risk information, see our website. To schedule a Free LASIK Consultation, give us a call today at 415.921.7555 in San Francisco and 650.755.6900 in Daly City.

Omega-3 Fatty Acids and Your Eyesight

Omega-3 fatty acids are definitely a plus in your diet. They are known as a ‘good fat’ for your diet – one that protects the cell membrane and is reported to protect you from certain health issues. One of these health issues, as reported by NPR (National Public Radio), is age-related macular degeneration. 

Age-related macular degeneration generally occurs in older adults. This condition results in vision loss in the middle of your line of sight, due to retina damage. According to the article, “Women who ate fish, a prime source of omega-3s, at least once a week were less likely to get age-related macular degeneration compared with women who ate fish just once a month, a new study finds.”

While all of this information is interesting to look at, the article also points out that the study is not complete.

There are always studies being done on vitamins and minerals. It’s important to know what is fact and what is fiction. Doing your homework is essential in preventative medicines, but the most important thing is having a complete eye examination. You eyesight is like a fingerprint – it is unique to you, and what may work for 5 or 10 other people may not necessarily be the best thing for you. If you think you may have an eye disease or your family has history of eye diseases, you should schedule regular eye exams for the best way to keep on top of it.

Laser Vision Correction and Dry Eyes

Perhaps the most common side effect to laser vision correction is dry eyes after a procedure. Most of our patients experience a little dry eye after a procedure. This temporary issue can be relieved with eye drops and it will correct itself within a couple of weeks.

According to FDA trials, 20% of LASIK patients still experience dry eye even six months after a procedure, like LASIK. While this side effect may be annoying, it can be treated with punctual plugs or medications.

At Pacific Eye Specialists, most all of our patients are free of this irritation after one year. This is why the post-LASIK follow-up appointments are absolutely necessary. We take your vision very seriously and we want to make sure you can see clearly for years to come.

LASIK works by correcting the cornea of your eye. LASIK can have you seeing clearly for many, many years, depending upon what age you receive treatment. If you are not a good candidate for LASIK, there are other procedures that can be performed to correct your vision. Learn more about laser vision correction with Pacific Eye Specialists.

LASIK and Your Retina

There is a misconception when it comes to laser vision correction procedures, like LASIK, and the retina in your eye. Some patients think that because they are having laser vision correction, any issues with their retinas will also be corrected.

This is not true.

Your retina is found at the back of your eye. It is responsible for sending messages to your brain. These messages tell your brain what you are looking at.

You have LASIK to correct a refractive error. Refractive errors occur when the cornea in your eye is misshapen. The cornea, which is found in the front of your eye, should be round and bowl-shaped. If the cornea is not perfectly shaped, then you will experience a refractive error: nearsightedness, farsightedness, or astigmatism.

Light is reflected off of objects and is filtered by the cornea of your eye. When the cornea is perfectly shaped, this light will refract directly onto your retina. If the cornea is misshaped, then the light will not shine directly onto your retina, and this causes double vision, blurry vision, or fuzzy objects.

LASIK works to reshape the cornea into a bowl-shape so that the light will reflect directly onto your retina. It does this through the use of a laser, guided by a surgeon. The laser only affects the cornea and not the retina, therefore it does not correct any issues you may be experiencing with your retina.

A board-certified surgeon should carefully analyze your eyes prior to approving you for LASIK surgery. Most of the risks associated with LASIK occur because the person may not be an excellent candidate for the procedure. Some of these risks include double vision, a fixed or rotating glare, rings of light (“halos”) or starbursts of light. There is also a risk of dry eye, however most patients will experience dry eye for a short time after surgery.

Contact Lenses and Eye Safety

Approximately 1 out of 20 people will have contact lens related problems.

Are you one of them?

Through recent research it has been found that contact lenses can affect several different areas of the eye. These effects could be simple irritation to more sight threatening complications. You may have experienced some of these problems or just had a concern about them.

The weather, oxygen and their effect on your eyes.

The weather and the wearing of contacts both have an effect. The eye cleans itself from harmful bacteria and other foreign substances through the process of creating what is known as the tear film. Not only does it protect the eye but it also carries the moisture and oxygen to help and protect the eye. The reduced amount of oxygen on the surface of the eye in turn reduces the blood flow to the cornea, which can create complications. While soft contact lenses have less of an effect on this than hard lenses it still does have an effect. And there are other problems that contacts can cause with your eyes.

Now throw in dry weather, the wind and the fluctuating temperatures you can see what your eyes are dealing with on a daily basis. In many instances, the risk to the health of your eyes is greater from wearing contact lenses than from today’s LASIK eye procedure, or other laser vision correction procedures.

And there are the aspects of “chronic wear and tear” from continual contact lens wear to the eye from simply having this foreign substance or particle in the eye. This can predispose an eye to infections and if you might have even experienced these difficulties yourself.

What are your alternatives?

LASIK is the alternative to contact lens wear. While not having them to affect your eyes in a potentially dangerous way is of great benefit you will also receive the benefit of having very improved eyesight if not 20-20.
