Lasek vs Lasik Eye Surgery !
Here I am not talking about my experience but my wife’s.
She went for Laser surgery for a problem of having a bad vision from far. It was in 2004.
She was like 40 years old at the time. The first step was to have an eye exam, to see if she was
a good candidate, and see if her vision would really change from the exam date, to the surgery date (6 months).
Second Exam .. ALL GOOD!!! Time for surgery!
Everything went pretty smoothly.. One of the
coolest thing I remember was that widescreen tv in the waiting room.
Thinking, Nice I will be able to watch a movie or something. NOT REALLY! . They were showing my wife’s surgery on it ..
That was super cool for me,but kind of unexpected! I don’t know about the patients that were waiting.. Her surgery went pretty good.
No incident. And we are out of there!!!
Then she had to wear those big (HANGOVER BABY ) Goggles for 48 hours,if I remember correctly.
Her pupils were so dilated that any little ray of light felt like a 5000 Watts spotlight on her face .
A couple of years after, one of her eye start to get weaker again and a little blurry .
At the time,the repair would have been free, but we were living in other province,etc..
So she never went . It is stable since, 15 years later.
I guess it is even easier today with a new technology called “SMILE”, but we will get there.
Let’s get some info now
Thousands of people are turning to laser eye surgery to correct their vision and eliminate their dependency on glasses or contact lenses. Like all medical procedures, laser eye surgery provides benefits, but poses risks.
Laser eye surgery is the most commonly practiced procedure to correct vision problems caused by refractive errors, including myopia (nearsightedness), hyperopia (farsightedness) and astigmatism (distorted vision when looking at objects at any distance).
More recently, laser eye surgery has also been used to correct presbyopia (the inability to focus on nearby objects), which is part of normal aging and can be corrected by using reading glasses.
Lasek vs Lasik Eye Surgery
Essentially, laser eye surgery refers to the process of reshaping the clear layer of your eye (known as the cornea) with a concentrated beam of light known as a laser.
One of the things that can confuse a lot of people is the difference between the two types of laser eye treatment. To understand the difference between the two, you first have to understand a bit about the concept of laser eye surgery in general.
Here is a video (5 Min) That will help you on that matter.
Number One : LASIK ?
LASIK stands for Laser-Assisted In-Situ Keratomileusis. It’s been performed for over 20 years and it’s helped to improve the vision of millions of people in that time. Believe it or not, the treatment is considered so effective that NASA has even approved it for use on their astronauts.
During LASIK treatment, the first laser will create a very thin protective flap on the clear layer of your eye (your cornea). This protective flap will then be lifted, and the second laser will then be used to correct your vision. Both eyes are usually treated on the same day.
The recovery process is fairly quick and you should be able to drive and return to work within 24 hours of the treatment. Many people notice an immediate improvement in their vision but for others it may take a few weeks for their vision to settle properly.
Number Two : LASEK ?
LASEK stands for Laser Assisted Sub-Epithelial Keratectomy. It’s a better choice if you have a thin cornea or a medical condition that makes laser eye surgery more challenging to complete. During the surgery only one laser will be used to correct your vision— rather than the two that are used in LASIK.
An alcohol solution is put on to the surface of your eye and an ultra-thin sheet applied. This alcohol solution loosens the thin layer of cells on your eye’s surface called the epithelium. These cells then stick to the sheet, which is then gently moved to the side of your eye, giving your surgeon access to the layer of your cornea which will be treated by the laser.
After the laser has reshaped your cornea, a special protective contact lens will be put on your eye to increase your comfort whilst it heals. This lens is normally taken off after about four days. Like LASIK, both eyes can be treated on the same day. A lot of patients can see an immediate improvement in their vision, but it may take a number of days for your vision to settle. The recovery process can take slightly longer, usually a couple of weeks. The slightly longer recovery time of LASEK is a small compromise to make when it comes to correcting your vision for the long term with laser eye surgery, something that you wouldn’t be able to benefit from otherwise.
“SMILE” there is a 3rd One
In the SMILE procedure, the surgeon uses a femtosecond laser to create a small, lens-shaped bit of tissue (lenticule) within the cornea. Then, with the same laser, a small arc-shaped incision is made in the surface of the cornea, and the surgeon extracts the lenticule through this incision and discards it.
With the tiny lenticule removed, the shape of the cornea is altered, correcting nearsightedness. The corneal incision heals within a few days without stitches, and sharper vision occurs very quickly.
Not Done Yet ! “Blended Vision”
Blended vision uses laser eye surgery to treat one eye for distance vision and the other for close-up distances. After surgery, both laser-corrected eyes will work together, ‘blending’ their focus to give you a wider range of vision.
But it’s not something that every patient will get used to overnight. We rely on our brains to interpret what our eyes tell us, translating the data that comes through our corneas into information that makes sense in our minds. However, blended vision represents a big change in the visual signals we receive. With each eye optimized for a different distance, it’s normal at first to experience ‘visual confusion’ when experiencing this new way of seeing.
Is laser the right solution for you?
1- Not Even 18
Lasik results are permanent. However, a person’s eye can change throughout life. Little is known about how vision changes in a child’s eyes and what influences those changes. Vision can change dramatically during the adolescent years. For this reason, results of Lasik may be temporary or unpredictable. Lasik is not recommended for anyone under the age of 18.
2- Pregnant or Nursing
Having Lasik just before or after pregnancy is not recommended. Hormone fluctuations and perhaps fluid retention can cause changes to a woman’s vision corrective prescription during pregnancy. She may become more nearsighted or develop a bit of astigmatism during pregnancy. Hormone changes can lead to dry eyes during pregnancy and during breastfeeding. Dry eyes may make her eyes uncomfortable and could delay healing. The medications administered for dilation and after Lasik surgery could be absorbed through mucous membranes, which could be harmful the fetus.
Certain prescription drugs can interfere with Lasik results. For example Acne medications can cause significant dry eye. Having dry eyes can increase the chance of cornea scarring after Lasik. Your doctor will know if the prescription drugs you are currently taking are acceptable.
4- Unstable Vision.
You are not a good Lasik candidate if your contact lens or glasses prescription is fluctuating. Most doctors prefer your prescription to be stable for longer than one year. However, one year is a minimum. Prescriptions can fluctuate for a variety of reasons. Contact lens wear, diabetic blood sugar changes, and normal aging changes can cause your prescription to change over time. Lasik is a permanent procedure. It makes sense to make sure your prescription is stable before having Lasik eye surgery.
5-You are not in the shape of your life
Certain medical conditions can affect the way your body heals after surgery. Patients with autoimmune diseases are not good Lasik candidates. Many autoimmune conditions cause dry eye syndrome. A dry eye may not heal well and has a higher risk of post-Lasik infection.
Other conditions such as diabetes, rheumatoid arthritis, lupus, glaucoma, or cataracts often affect Lasik results. You should have had no eye infections or injuries within the past year prior to undergoing Lasik. Infection and injury can leave behind corneal scarring that may have detrimental effects.
6- Dry Eye ?
Having dry eye syndrome is usually a disqualifier for Lasik. A person with dry eyes has an increased risk for significant post-Lasik discomfort and a possible worsening of dry eye symptoms. Having dry eyes can also delay proper healing. This is not to say that a person with dry eyes cannot have Lasik. Your eye doctor will examine you to determine the severity of your dry eye condition.
“Perfect” Should not be on your mind!
While most patients who undergo Lasik have excellent outcomes, you should not expect perfect vision. Every patient heals differently after surgery. After undergoing Lasik, there is always a possibility that you may need to wear reading glasses or corrective lenses for at least some activities.
If you expect perfection, you should reconsider having Lasik.
Your Pupils Dilate More Than 7 Millimeters in the Dark
During Lasik, the area of the eye that will be lasered should only be 6 mm in diameter. This is true with most lasers used during Lasik. If your pupil normally dilates to 7 or 8 mm in the dark, you will probably have unwanted glare, halos or starbursts around lights at night time. This is becoming less and less of a side effect. Special pupillary testing is usually done as a part of the pre-Lasik measurements.
Patients with extreme levels of myopia and corneal thinning, or keratoconus, may not be LASIK candidates. You should be thoroughly evaluated by an ophthalmologist prior to proceeding .
