Lasik eye surgery is a new opportunity to see without glasses.
Read more on LASIK to correct your eyesight:
The natural lens of your eye is able to change shape, letting you focus.
As you get older, your lens starts to lose the ability to do this and becomes stiff.
This leads to the need for reading glasses or prescription glasses.
What Does Lasik Mean?
Lasik eye surgery involves reshaping the cornea by using a laser underneath the corneal flap. This laser is a highly specialized laser called an excimer.
Joannis Pallikaris in 1991 first developed the excimer laser to treat refractive errors, improve vision and eliminate or reduce the need to wear glasses.
“LASIK” stands for Laser-Assisted In situ Keratomileusis.
How Lasik Works
An eye surgeon trained in this special procedure will first create a highly précised cornea flap with a thin hinge. The flap is then pulled back, exposing the corneal tissue, allowing the excimer laser to reshape the cornea. The surgeon will then gently reposition the flap back onto the cornea without using sutures.
A person might decide to have Lasik eye surgery when the eye can no longer focus evenly. The cornea or front surface of our eye is what focuses the light rays on the retina’s surface.
Our eye works very much the same as a camera lens. In an eye that works perfectly, the lens and cornea align with the eye length and bring clear focus. When these are not matched, there is refractive error.
Primary kinds of refractive error:
1. Near-sightedness or Myopia- when distant objects no longer look clear, but near ones do.
2. Hyperopia- near objects look blurry and distant ones clear.
3. Astigmatism- the shape of the lens or cornea is distorted and all distances appear unclear.
Different Lasik Procedures
In a certain sense, all laser procedures are very similar, but there are lasermanufacturers who have designed their own specific excimer laser.
The different types of surgeries are:
1. Conventional Lasik surgery
2. Wave front-optimized treatment, and
3. Wave front-guided treatments.
Conventional Lasik Eye Surgery
Most people will choose this method if there are no underlying problems.
This type of laser is based directly upon a person’s prescription with fixed parameters unique to each person.
The treatment is generally effective, but can cause night vision problems and glare.
Wavefront Optimized LASIK
This type uses the Wavelight laser.
It is also based on your prescription, but takes the corneal curvature and thickness into account.
The laser is applied to the outer edge of the cornea.
This type of laser has been shown to reduce the complications of the conventional laser, such as glare and other night vision problems.
Wavefront Guided LASIK
This type is often referred to as custom LASIK.
In addition to treating your basic refractive error, it can also make specific corrections like high order aberrations.
Special mapping of your optical system is done before surgery to identify any irregularities.
Severe irregularities can affect your quality of vision, depth perception and night vision. Wavefront guided LASIK can treat these irregularities.
Making Sense of Lasik Eye Surgery
Are YOU a candidate for Lasik?
Like any surgery, there are things to be aware of about Lasik eye surgery:
1. There is a low, but real risk, unavoidable complications can still happen.
2. Vision needs to have been fairly stable over the past years.
3. Other health conditions need be taken into consideration.
4. Contact sports such as wrestling or martial arts may cause trauma so opting for another refractive procedure might be better.
5. A person with a corneal disease like Keratoconus is not a candidate forLasik eye surgery.
It is essential to obtain a comprehensive doctor evaluation.
Your doctor will check for any risk factors to see if you may be a good candidate for the Lasik eye surgery. The doctor will check:
1. High prescriptions
2. Thin corneas
3. Corneal curvature that is abnormal
4. Dry eyes
5. Large pupils
6. If you have previously had refractive surgery.
Lasik eye surgery can be a wonderful improvement to waning eyesight, but it is very important to be aware of exactly what you are having done to your eyes. Today there are more and more people choosing this option over wearing eyeglasses.
Do some research and talk to your doctor about the benefits and drawbacks of Lasik eye surgery.
Lasik eye surgery is a surgical procedure to repair a person’s vision regardless if the person is suffering from near-sighted view, far-sighted view or astigmatism, or any kind that requires the person to wear spectacles for better view.
The surgery will let the surgeon to replace the patient’s cornea so that the alignment between the cornea and the lens are correct.
Such surgery will definitely heal patient’s vision problems and ultimately let the patients be free of spectacles or contact lenses.
However, there are precautions that one must take when considering the surgery even though there are many advantages to gain after.
There are risks to be considered when considering Lasik eye surgery.
The eyes are the most sensitive organ in a humans’ body so to treat it would require extra care.
Maintaining the eyes after the surgery is even more critical.
For those who have different eye vision power (that is, those who have 2 different vision powers for their eyes) suffer more risks.
Although these risks rarely happen, you never know as to what complications may arise after surgery which can range from simply just having dry eyes to having double vision or ghost vision.
A symptom that may arise is that the surgery went smoothly however the patient’s eyes have been over-repaired.
Such cases would require the patient to re-do the surgery because they are uncomfortable with the amount of light that their eyes now capture from both the sun and electrical light sources.
Although the reason for the surgery is to cure those with vision problems, a few patients might find the need to wear spectacles or contact lenses again especially those who suffered from far-sighted visions.
As we age, our eye sight becomes weaker thus would result to far-sightedness.
Even with the surgery, one may still need to wear spectacles after a few years because the muscles in our eyes are getting weaker and eventually no surgery could correct it.
This could also happen to those with near-sighted vision as well as astigmatism.
Regardless of the risks, the result after the surgery without problems and with critical care is amazing.
One may rid their spectacles for a long while until age catches up.
Patients need to be aware that the care of the eyes after the surgery is riskier than during the surgery itself.
Whilst the eyes are healing, the tissues and muscles in the eyes are very sensitive and could easily be damaged.
However, most people are delighted with their results, especially now that LASIK costs have become so reasonable. In fact, Lasik surgery cost continues to benefit from competition and is increasingly a manageablke investment, at least for folks in countries like the US and Australia.
