can presbyopia treated with LASIK?
I might have an image of the thing that myopia heal speaking of LASIK. Certainly Not long ago, is what presbyopia was told that it can not LASIK. However, recently it developed a new technology, we also close far become visible "presbyopia treatment LASIK" has been attracting attention.
By the way, the cause of presbyopia?
presbyopia that occurs in the decline of the focus adjustment function
the way and is presbyopia, why would become? It happens to decline the focus adjustment function of the eye by aging. Eyes blurred, eyes get tired easily, is subjective symptoms of presbyopia initial symptoms such as blurred character of the newspaper.
well presbyopia and hyperopia are mistaken for the same thing but, presbyopia is different from the hyperopia. Presbyopia is and that the function of changing the thickness of the "lens" of eye drops, it takes place in the cause of the elasticity of the lens itself is slowing down "regulatory function abnormal".
for hyperopia, it is a short length of the eye and can occur because of the refractive power of the lens is originally weak. Rather than a regulatory function problem, it is become behind than the position is retina in focus "refractive error". By the way, myopia and astigmatism, in the sense that in focus position deviates from the retina, is hyperopia Like "refractive error".
happen to everyone from time past the 40-year-old
exercise due to aging Just as there are individual differences in the beam of the decline of the decline and the skin of ability, also there are individual differences in time to realize presbyopia. Lens is said to be going to lose slowly elasticity from a teenager, it seems there are many people who feel the appearance Zura of since I generally older than 40 years old. However, the difference in time is there, is what happens anyone.
are measures and method for the treatment of presbyopia?
to use reading glasses
the most popular thing is the reading glasses as presbyopia measures. Very simple reading glasses are generally intended to be adjusted so that is easy to see things at a distance of about 30 centimeters from the eyes, for example, read a book, you use when you can see a computer monitor.
There is a theory that presbyopia advances and use reading glasses, perhaps this is superstition. Unreasonable than to put up with is, without causing a tired eyes who use the reading glasses that degree is properly aligned, is what becomes difficult to feel the decline of vision.
In addition, there is a theory that originally people were myopia myopia heal when it comes to presbyopia, but it is also unfortunately superstition. Myopia because as mentioned above "refractive error", will take place in parallel rather than to offset the "regulatory dysfunction" of presbyopia. Therefore, will also be difficult to look far for nearly a person of myopia is presbyopia. If the people of myopia has become presbyopia, you may want to correct vision in bifocals.
perform a surgical operation
surgery to cure presbyopia is roughly There are two. One is surgery to correct the cornea by irradiating the laser on the cornea of the eye, varying the refractive index. Widely surgery how to use the laser is called "LASIK".
Another method is the surgical method of injecting and fixing the lens and the plate in the eye. Nickname has the nickname of the variety and the like "intraocular contact lens" and "eye in the camera," "camera inlay". In addition, there is also a surgical method to combine the "camera inlay" and "LASIK".
what kind of surgery I presbyopia treated with surgery?
myopia surgery contents are almost the same of bifocal LASIK
LASIK as described above with, is surgery to make connecting correctly image on the retina to correct the cornea with a laser. In the bifocal LASIK, and correction and divided the cornea by the distance to the object to be seen. For correction technology so as to meet the long-range, medium-range, short-range, each developed, became possible bifocal LASIK.
in
bifocal LASIK, and corrected in a state of wearing the contact lenses of the so-called bifocal the cornea, and to restore the vision. Medium-range compared to the glasses of bifocals is also easy to see the benefits, but it is said that it is not suited to correct far and near together strongly.
bifocal Faye kick
and Faye kick, eye a soft small lens It is surgery to fixedly mounted within. There is also be referred to as "intraocular contact lens". Lens to be used will be used the equivalent of the lens that is used in cataract surgery.
Replace the
However lens and population lens in cataract surgery, but it is common for mounting the lens on top of the lens in the Fay kick. Relatively easy to fit in the case of severe myopia, it goes also to the person who the ideal vision was diagnosed with not be obtained by LASIK.
presbyopia treatment camera
eyes that look as bad people also Squinting There will ne. The presbyopia treatment camera, is a surgery to correct vision by using the same "pinhole effect," as when you squint.
In presbyopia treatment camera surgery called "camera inlay", put a very thin and a hole in the middle like a donut open film to the cornea, and secure. By pinhole effect of "camera inlay" were placed, to adjust the position to form an image, it says that it can correct the short-range vision not drop the long-distance vision. There is also a facility referred to as a "leading eye" is by the hospital.
monovision LASIK
and mono vision LASIK, to correct vision in LASIK in time, as far the eye is easy to see, the other is the treatment to be adjusted to nearly easy to see.
monovision LASIK to adjust easier to see with perspective when viewed in both eyes, myopia is said to be a strong person easy to be the ideal field of view can be obtained, even if supplemented vision glasses, the normal life it is benefit to be able to send to the naked eye.
The disadvantage is, it takes some time to get used to the appearance of the specific. In addition and people to the long-term operation, it is to be said that is not suitable for those who for a long time is a personal computer work.
as well as cataract surgery, multifocal lens surgery to use an intraocular lens
in cataract surgery, and insert the excised artificial lens a white cloudy lens. At this time, the place is a typical cataract surgery that uses a single-focus intraocular lens, the also to treat presbyopia by inserting a multifocal intraocular lens is a multifocal intraocular lens surgery.
In the conventional single-focus intraocular lens, whether near or far away, because it was not the focal point can be matched to only one, the general that is after you have put the intraocular lens in cataract in combination with glasses It was specific. However, by selecting the multi-focal lens, is said to be if normal daily life about better even without a combination of glasses.
also multifocal in the intraocular lens can be simultaneously correct astigmatism "multifocal toric intraocular lens" has also been developed. It seems to still have limited facilities to handle in Japan, but it is good news for people who suffer from astigmatism and presbyopia.
anxious of LASIK surgery cost
LASIK health insurance applicable!
refractive surgery of the cornea caused by LASIK, does not apply Unfortunately health insurance. Because that is, free medical care, you have to self-pay all the costs. It costs there is a difference by the facility to undergo surgery, but it is said that generally take up to 400,000 yen.
also health insurance is no good, I also is a place to be worried about whether the security interest of the medical insurance. About this matter, examine the medical insurance that contains your "LASIK surgery is whether the benefits subject to medical insurance," There is no choice but to confirm.
Although many of the medical insurance seems LASIK be outside for security, that insurance period is that there is a possibility to be recognized as also for security if LASIK surgery if the previous one in 07. If are considering LASIK, let's examine all means once.
use of the medical expense deduction system
presbyopia treatment LASIK in this way in insurance coverage you can not expect too much, but let's consider the medical expenses deduction as measures to reduce the self-burden of the cost even a little.
is a medical expense deduction, that the medical expenses of the year if it exceeds a total of 100,000 yen, income tax in accordance with the medical expenses of the amount that exceeds the to and 100,000 yen a tax return is refunded Thing.
will be required to submit a "final return stating the matters related to medical expenses deduction." About how to how to create and filing of documents, For more information, please reference to the Internal Revenue Service of the Web site.
there is a sequelae to LASIK surgery? !
a decrease of vision occurs also
is eyesight was restored by LASIK, there is no unfortunately forever. Considered to fall again vision within that elapses some years, some people expressed as sequelae of LASIK vision loss.
a few years ago, but hospital sloppy hygiene management gave the sequelae to many patients in the cause has been a problem, this is let's say that the case is not good for a small part.
to stabilize the vision after LASIK, there is a need to review the lifestyle that put a strain on the eyes. That you do not continue to use a long period of time your computer or smart phone, sometimes able to see far away, watching TV or lying down, that you do not read a book, will be the like that you do not use a smartphone and personal computer in a dark room.
corneal ectasia
after undergoing LASIK surgery, that the cornea to expand Yes, it is said that the proportion of about one out of people 10,000 people its incidence is undergoing LASIK surgery in the estimation. Cornea becomes astigmatism and expand, vision will waning rapidly.
does not cause the clear cornea expansion occurs after LASIK, but unrelated illness and LASIK, there is a disease that the central cornea that keratoconus projects. Many of keratoconus onset in growth phase, progression of symptoms when it comes to adult is said to stop, but of letting develop keratoconus of presymptomatic by LASIK surgery? And, it seems being questioned between professional family.
whether so subject to inspection to adapt to always surgery before LASIK surgery, is either in the preoperative examination has been testing firm that there is no suspicion of keratoconus it is a good idea to confirm.
Hello Groix phenomenon
the Hello Groix phenomenon, light is abnormally glare felt terrible when is the symptom not be opened firmly on the eye. Car lights and street lights There is also a symptom that appears to spread like idly draw the wheel at night. Light by the difference between the part that has not been corrected and the corrected portion of the cornea is said to be bent by LASIK, it will be naturally eliminated as much as half a year a lot after surgery.
dry eye
during the LASIK surgery, part of the cornea of the nerve is cut it is that is that it may cause a dry eye in the cause. Symptoms of dry eye is there are individual differences, some people also undergoing LASIK surgery not a dry eye. In addition, it seems that often subside symptoms in about six months from three months in people who came out symptoms.
myopia correction LASIK prone to presbyopia?
aware of the presbyopia that did not notice
"prone to presbyopia and the myopia correction LASIK," that you have heard the story of "presbyopia is accelerated," Do you have any? When I say the conclusion, it is a rumor.
people of myopia is aware of presbyopia difficult condition, because it is in focus originally near. However focus position becomes far by receiving a myopic correction LASIK, become to feel the hand is difficult to read than before surgery Will feel as "presbyopia is premature."
In addition, presbyopia is the loss of focus adjustment function. Regardless of whether not receiving or have undergone LASIK surgery, everyone also is what becomes difficult match in focus by aging. However, the original people were myopia there are still stores that hand was clearly visible. For this reason it is said that one does not feel that "before the hand is more clearly no longer seemed to have appeared" equal "presbyopia is premature in LASIK."
