Free online lasik eye test


 What is LASIK
LASIK is a refractive procedure done to correct nearsightedness (myopia), far-sightedness (hyperopia) and astigmatism. LASIK modulates the shape of the anterior surface of eye (Cornea) so that the power of glasses is almost eliminated.

Frequently Asked Questions About LASIK


How does LASIK work?

The term LASIK literally means “to reshape the cornea from within using laser”. After drops are used to numb the eye, a small flap of tissue is gently lifted from the front of the cornea. The laser is then used to reshape the cornea into a flatter curvature, this procedure lasts 10-90 seconds. The flap is then replaced and heals without the need for stitches.

Will I be put to sleep?

No. You will receive several drops of topical anesthesia to numb the eye. In addition to the drops, you will also be given an oral medication to help you relax.

Is there any discomfort to LASIK?

Most do not experience discomfort during the procedure. Some patients experience a mild sensation that may feel like an eyelash in the eye during the first evening. 

How long does the procedure take?

Patients begin receiving eye drop medication just prior to the procedure. The procedure itself takes approximately 15 minutes per eye, with the actual laser treatment time lasting 10 to 90 seconds per procedure.

When can I go back to work?

With LASIK, most patients can return to work within 1 - 2 days

Routine Eye Care Frequently Asked Questions

Are routine eye exams important?

Yes. Routine eye exams are important even for people who are not experiencing eye
trouble. 

What are routine eye exams?
These are in-depth procedures that are usually performed by either an Ophthalmologist or
Optometrist. 

How often does a person need an eye exam?
Annually.

What to expect from an eye exam

Using a light source, an external examination ensures the eyes 'look' right. You'll follow
the doctor's pen (or other object) with your eyes to ensure the eye muscles function
properly. When you read the illuminated chart with letters that get smaller the further
down you go, your doctor is checking your visual acuity. 

If you need corrective lenses, you'll get a refractive assessment, a test that determines
how light waves bend. The results of these tests help the doctor determine your
prescription. He may put a Phoroptor, a device that resembles a big black mask, over
your eyes in order to fine-tune these measurements. 

Your peripheral vision will also be tested. A slit lamp exam uses a microscope that emits
a sharp beam of light to evaluate the cornea, lens and iris. The back of the eye is also
examined and finally your eyes will be tested for glaucoma.  

What is Hyperopia?

Hyperopia is often referred to as "long-sightedness" or "far-sighted". An eye is hyperopic
when the far point is at a virtual point behind the eye. Generally, the hyperopic eye is too
short with respect to the refractive state of the standard eye (ie an emmetropic eye or eye
requiring no optical correction) or because the optical power of the eye is too low relative
to the length of the standard  eye. The focus is correctly adjusted using a "plus" lens
power or convex lens.

What is Astigmatism?

Astigmatism is an irregularly shaped cornea, resulting in a vision error that occurs when
light rays entering the eye scatter instead of providing a single focal point. Regular
astigmatism is the most common type, in which the shape of the cornea resembles a
football.  Astigmatism can usually be corrected with eyeglasses, special contact lenses
(toric lenses) or surgery.
What is Presbyopia?

Presbyopia is an age-related process usually beginning in the 40s, people with presbyopia
experience blurred vision at near points, such as when reading, sewing or working at the
computer.  It happens to everyone at some point in life, even those who have never had a
vision problem before

What is low vision?

Low vision is a term describing a level of vision below normal (20/70 or worse) that
cannot be corrected with conventional glasses. Low vision is not the same as blindness.
People with low vision can use their sight. However, low vision may interfere with the
performance of daily activities, such as reading or driving. 

Can I use my eyeglass prescription to buy over-the-counter contact lenses?

No, because it does not provide the specifications for lens diameter, thickness and base
curve. A new prescription must be carefully fitted by an eye care specialist to avoid
serious adverse reactions. 

Are sunglasses good for my eyes?

There is a benefit to wearing UV protective lenses--wearing them may protect against
cataract formation. Clear lenses with UV protection may offer greater protection than
dark lenses because they allow the eyes to be exposed to more light. This causes greater
constriction of the pupil which lets less light enter the eyes. However, someone with
extreme light sensitivity should protect their eyes with polarized lenses.
