Astigmatism: FAQs

Q: Does is astigmatism cured?
A: Sorry, no. In fact, sometimes astigmatism worsens with age … however slowly. It is probably partly genetic and also partly environmental. A lot of astigmatism can be conveniently corrected with spectacles, contact lenses as well as refractive surgical treatment; however significant astigmatism won’t go away on its own. The good news is, it is not a fatal problem!

Q: Could you please discuss what is meant by the term “mixed astigmatism,” and also if this problem can be treated with LASIK?
A: In mixed astigmatism, the unequal curvature of the cornea, the front, clear part of the eye (and in some cases additionally the lens inside the eye) creates one meridian of the eye to be farsighted and a 2nd meridian (perpendicular to the first) to be near-sighted, that is why it is called mixed astigmatism.
Mixed astigmatism typically can be successfully treated with LASIK, however results might be less predictable than surgical correction of straightforward or simple near-sighted astigmatism. Your eye surgeon can review this with you carefully at your LASIK examination, making you understand the pros and cons.

Q: I have astigmatism. Would you suggest using contact lenses or just glasses?
A: It’s your selection. Both contact lenses and also spectacles can remedy astigmatism. Refractive surgical procedure, such as LASIK or PRK, also is a choice.

Q: My ophthalmologist informed me at my eye examination that my astigmatism worsened. Is this typical? I heard that astigmatism’s not intended to change.
A: When it concerns your eyes, it’s surely best to trust your eye doctor as opposed to what you listen elsewhere – unless that “in other places” is one more eye doctor at Khanna Vision Institute!
Astigmatism is a really typical vision problem. Actually, most individuals have some astigmatism. When you have astigmatism, light does not concentrate to a single point in your eye. Rather, it causes blurred vision due to the fact that the front of the eye is shaped more like an American Football than a baseball.
Unfortunately, astigmatism can (and frequently does) change throughout your life, generally for the worse with age. However, astigmatism is not an illness and can be made up for with glasses, contact lenses or refractive surgical procedure.

Q: Our child is nearly ten years old, and also, he had his very first eye test recently because he failed a school vision testing. The eye doctor said he has a lot of astigmatism in one eye, as well as a lesser amount in the other, for which he needs to wear glasses regularly because he has “lazy eye” in the eye with higher astigmatism.
The medical professional went on to state that the lazy eye might be long-term because the astigmatism had not been spotted earlier. Is this true?
A: It’s true that uncorrected astigmatism can trigger amblyopia (or “lazy eye”). In the past, it was thought that there is an “essential period” in childhood during which amblyopia therapy should begin or reduced vision will be permanent. Many people believed this essential duration ends around age 8 or 9.
Yet current research studies of brain function and also a phenomenon called neuroplasticity are eliminating the belief that amblyopia therapy is inadequate past a certain age in youth.
Make sure your son uses his eyeglasses permanently as well as sees an optometrist for regular exams to monitor his vision advancement. At first, the optometrist must be seen a lot more regularly than once a year.
You also could wish to take him to an ophthalmologist who focuses on your youngster’s vision and amblyopia therapy. A program of suggested visual tasks (called vision treatment), along with full-time wear of eye glasses, usually is much more effective at minimizing or getting rid of amblyopia than simply wearing prescription eyeglasses.

Q: Will my astigmatism worsen if I don’t use my glasses at all times? If I do use my glasses at all times, will this somehow reduce my astigmatism, or will it make my astigmatism get worse? Does using glasses help in reducing astigmatism? Are there any medications that can lower astigmatism?
A: Wearing or not wearing your eyeglasses will certainly not make your astigmatism much better or worse. If your astigmatism worsens, this will occur whether you wear your glasses or not. Today, there is no well-known medicine that can minimize astigmatism.
But we advise, that you do put on prescription glasses or contact lenses (or think about LASIK or other vision surgery to remedy your astigmatism) if your vision problem is aggravating without corrective lenses. Also, light uncorrected astigmatism typically produces migraines and also eye strain.
Also, depending upon the seriousness of your astigmatism, it might be dangerous (and prohibited) for you to drive without corrective lenses.

Q: I have actually used glasses before, however I was just suggested glasses for astigmatism for the first time. My brand-new glasses make me dizzy when I wear them. I have actually had them for three days. Will this feeling vanish, or should I go back to my optometrist?
A: It’s true that sometimes it takes a period of time to get used to glasses that remedy astigmatism – particularly if you have moderate or high astigmatism or a significant correction in your astigmatism prescription.
Because it’s been 3 days and you are still uncomfortable (I’m presuming you are wearing the glasses full-time), I recommend you return to your eye doctor to ensure your new eyeglasses prescription is appropriate and also your lenses were made properly.

Q: At what age can children have LASIK surgical treatment to correct astigmatism?
A: You don’t want to proceed with LASIK surgical procedure till you are reasonably sure your youngster’s eyes have actually stopped changing. Several youngsters who have astigmatism also have some near-sightedness, which commonly continues to worsen in the teen years. Most of the times, the minimal age for LASIK is 18 years, and also some individuals ought to wait much longer.

Q: My eye doctor told me that I have astigmatism in one eye and said I might as well get glasses if I intended to. He really did not appear very anxious about it. Should I get glasses?
A: If you have just mild astigmatism in one eye, and you see acceptably well without glasses (20/40 or much better, which is the legal requirement for driving anyways), and also you are not bothered by eye strain or migraines as the day goes on, prescription spectacles definitely are optional for you. Yet if your vision troubles you or you experience headaches or eye strain, I recommend using them.
If you doubt that, you might wish to go back to your eye doctor and have him or her tell you once more how much better you will see with prescription lenses. This can be demonstrated in the test room without the requirement for you to purchase glasses first.

Q: My spectacles prescription claims the axis of my astigmatism is 140 degrees. But when I got my glasses inspected, the lens claimed the axis is 160 degrees. Is it unsafe to put on these glasses? Will it make my astigmatism even worse?
A: It will not damage your eyes or make your astigmatism worse, however using glasses with an inaccurate astigmatism axis of this magnitude (relying on the amount of astigmatism you have) will generally trigger blurred vision, eye strain and various other discomforts. Go back to your ophthalmologist at your earliest convenience to recheck your prescription as well as the eyeglasses.

Q: I had cataract surgical treatment in both eyes, as well as it seems like I see less well now than before the surgery. I was informed I have uneven astigmatism. I did obtain glasses, which remedied it, yet without them, my vision is even worse than it was before cataract surgery. Can anything be done?
A: You may have more than one kind of astigmatism considering your cataract surgical treatment. Glasses can deal with regular astigmatism, yet they normally cannot fix irregular astigmatism.
Occasionally, astigmatism (both regular and also irregular astigmatism) is induced by cataract surgery. This is due to the fact that a laceration must be made in the front of the eye for the surgery, and as this wound heals it can alter the curvature of the clear front surface of the eye (the cornea). Additionally, sometimes astigmatism can be brought on by the placement of the lens implant inside the eye or the implant itself.
If you are dissatisfied with your vision without corrective lenses after cataract surgery, commonly there are alternatives to improve your sight with a follow-up refractive surgical treatment. If you’ve not yet reviewed this possibility with your cataract specialist or a refractive specialist that carries out LASIK, PRK and also other vision modification procedures, I advise you do so.

Q: At what age does astigmatism typically occur? I have actually been putting on glasses since I was about 9 or 10, and I started using contacts at 16. I’m 22 currently. In the past couple of years, I have actually been told that I have astigmatism.
A: Astigmatism often begins in early childhood years, but it can take place at any age. In some cases, using contact lenses can trigger astigmatism, particularly if the amount of oxygen reaching your corneas is significantly minimized for extended durations. This contact lens-induced astigmatism normally is temporary, yet it can perhaps be long-term.
If your astigmatism continues to change, ask your ophthalmologist if your contact lens wear might be a variable, and if you must attempt a different type of lens or reduce the time you wear your lenses.
