Because it is more complicated than myopic surgery.
Which also means that it is much more dangerous. People who undergo hyperopic laser surgery are having limited chances of positive long-term results, and recovering from the surgery takes much time.
In this article, I will share with you on how it is done and the untold truths about it.
"I read the editorial on advertising in ophthalmology with great interest and wholehearted agreement. The seemingly progressive tendency to irresponsible advertising, particularly of laser in situ keratomileusis (LASIK), is becoming an embarrassment to all of us who wish to practice ethical medicine and do no harm to our patients."
Steve Arshinoff, MD, J Cataract Refract Surg, 2004
These LASIK advertisements were gotten from billboard and Facebook.
They mislead readers to think that the side effects (even if permanent is ok) as long as you get the 20/20 vision.
By giving you the money guarantee, they portrayed that LASIK is safe with no potential risks and somehow the surgery is reversible.
In reality, will you be satisfied if you get back your money if the surgery failed and cost you your eyesight?

LASIK stands for Laser-assisted Intrastromal Keratomileusis. As you had guessed, laser is being used in the procedure.
The whole procedure takes about 15 minutes for both eyes. After you lie down on the surgical bed or chair, a retainer will be used to keep your eyelids open.
Then a suction will be used to keep your eyeball still while they use a surgical knife to cut your outer cornea creating a flap.
The flap is supposed to act as a natural bandage at the end of the procedure.
It sends shivers down my spine when I imagined myself sitting on the operation chair and wait for my cornea cut to be cut. I think I will probably faint by the time they place the suction on my eyes.
Evaporating Parts Of Your Cornea (Farsightedness)
Then comes the deadly laser. In LASIK for farsightedness, the laser procedure is way more complicated than it is for nearsightedness.
The ophthalmologist need to make the edges of the cornea thinner than the center. The cornea is supposed to act like a plus lens focusing the light onto the retina.
The cornea is reshaped by removing a ring of tissue around the outer edge of the cornea. By leaving the center of the cornea thick and thinning the outer ring, making it a convex shape.
The process becomes even more complicated if you have astigmatism.
All these techniques are very difficult to perform well. The bulging may not be centered or spherical, causing regular or irregular astigmatism.
Knowing just how much energy to apply and where, is an art as much as it is science. Thus creating higher possibility for the surgery to go wrong.
Won’t you be worried about whether the doctor will make mistakes? I do. I am very worried.
For all type of laser surgery for hyperopia, the cornea eventually regress back to its original shape. The only difference is the rate of regression which is so far slower for all LASIK style surgery.
In 2009, the former branch chief of Food and Drug Administration Morris Waxler, stated that the approval of LASIK devices in 1998 was made due to the pressure from ophthalmologists, despite high incidence of complications. He told ABC that reviews and investigations were not taken seriously enough. "I think we screwed up," Waxler said of the 1998 approvals. "Nobody's going to admit that.”
The optical industry claimed that 95% of patient who had went through LASIK are satisfied with the result.
Considering there are millions of people doing LASIK every year, 5% of that millions can amount to a lot.
In fact, these 95% satisfactory does not take side effects such as dry eye syndrome, sensitivity to light, starburst, halos, ghost vision and permanent night blindness into considerations.
See the report below.
Patients undergoing LASIK procedures display an increase of halo phenomena around lights in night vision conditions, even when the results of the surgery are considered entirely satisfactory according to current international standards of predictability, efficacy and safety.
Villa et al, Br J Ophthalmol, 2007
These side effects can be destructive to a person’s way of life. People lose their ability to function normally in their life, drive cars and travel at night.
As long as patients have improvement in their eyesight, the doctors considered them as "satisfied" customers.
Only a certain percent of patients achieve 20/20 vision without glasses or contacts.
Even though most operation comes with an enhancement surgery for free, the additional treatment may not be possible as it depends on the thickness of your cornea left after the burning from the first surgery.
It is important to note that even though the patient may appear well after the surgery, they may be unaware of some long term consequences which they were not told by the ophthalmologists.
These consequences may lead to eventual blindness.
We are also just now learning of some of the long-term complications of [LASIK], which are being reflected in new allegations and lawsuits. For example, some patients are developing postrefractive ectasia years after the procedure; this condition not only compromises vision, but also may need to be treated with a corneal transplant.

The long term consequences may include: (Comprehensive list can be found here in Dangers of LASIK).
So before you start paying your opthamologist the $2000 for an eye, please check out the complications and know what you are getting yourself into first.
If you are still not convinced that LASIK surgery is a dangerous thing to do, check out the video below.
The interview includes interview of people who suffered from permanent side effects of LASIK and the story of a policeman who suicided due to depression after LASIK surgery.
LASIK Fixes Only The Symptoms
Please remember that for most people, bad vision habits is the cause of bad eyesight. Eventually, your vision will decline.
Even if you took LASIK, whatever caused you to have farsightedness in the first place is still there.
As such, LASIK is like medication, they only solve your symptoms not the cause. It just not worth the risks of all the long-term complications.
Exit from your consideration of LASIK for farsightedness now, and thank me later for it.
