No, every eye is different, but in general patients must be 20 years old, suffering from a stable visual defect and showing no progressive eye disease or untreated general disease.
Have less than 20 years old; unstable visual defect; a distorted; fragile or too thin cornea; eye diseases like cataract or glaucoma, immune system diseases and pregnancy.
The procedure itself is painless thanks to the anaesthetic drops that are used to numb the area. However, the eyes may feel a bit gritty after the surgery for a few hours, but there is no pain.
Yes, for better security and efficiency, both eyes are treated during the same session unless constraints or complications.
Patients have the right to choose a treatment in two sessions (each eye apart).
This is a common concern, but rest assured that blinking and moving during laser surgery usually is not a problem. Numbing drops are applied to your eyes prior to surgery to make your laser procedure comfortable and decrease your natural urge to blink. Also, a small device will hold your eyelids open during the procedure so you can’t accidentally blink and your eyelids cannot interfere with any step of the surgery.
If your eye had to move even a millimeter, then the eye movement sensor (eye tracker) interrupts the laser. Which will restarts few seconds later after a refocusing of the device.
No, this procedure is performed as an outpatient. The patient comes 20 minutes before the operation and leaves the center 30 minutes after the treatment.
The operation is performed under local anaesthetic and without any injection. Only simple anesthetic drops are instilled into the patient.
A calming tablet is offered, half an hour before the procedure, if the patient feels the need.
It would be extremely unusual for anyone to go blind from laser refractive surgery, especially if you follow your surgeon’s instructions and attend all follow-up visits as directed.
That said like with any surgical procedure, unexpected complications can occur. Most Laser risks and complications are mild and can be managed successfully.
Laser surgery treatment is generally stable and permanent. However, it is essential to remember that changes can always occur in the eye. This is why it is recommended to have 20 years or more and especially have a stable correction before having this kind of intervention.
In general, all kind of visual defect (myopia, hyperopia, astigmatism and presbyopia to some extent) that are correctable by glasses and contact lenses are also correctable by laser. However eye diseases such as cataract and glaucoma can’t be treated by laser surgery.
To ensure the stability of the visual defect, patient must be 20 years old to get this kind of treatment. After the age of 20, patient can be treated at any age. There is no age limit.
The refractive laser technology has existed for over 20 years. And every year technological innovations (processes and machines) make it more relevant and effective.
It has been proven that laser eye surgery is safe and effective. Although no one knows the exact number of complications, studies suggest that the risk of serious incidents such as lost vision is thought to be less than 1 percent. However, rare cases may show some minor complications but again outcomes generally are very good.
As with any surgical procedure, some people may experience dry eye after laser, which usually is relieved with eye drops and disappears over time. Others may experience starbursts or halos around lights, especially at night. Usually this effect lessens or disappears over time, too.
You will return the next day to see your surgeon, then one week later to check the visual acuity and see if there is no complication. The surgeon usually prescribes an antibiotic and anti-inflammatory drops as well as artificial tears drops for a treatment of few days.
Immediately following the procedure you may feel a temporary burning or itching sensation as well as some blurry vision and haziness. However, clarity should improve by the very next hours.
On the other hand your visual defect (myopia, hypeopia or astigmatism) will be corrected immediately.
You will feel an improvement of your eyesight in the same day or the following day. You may be able to go to work the next day and start driving your car without wearing your glasses, especially if both eyes were operated on in the same session.
You can notice some side effects during the days after the procedure such as dry eye sensation, tingling especially when you rub your eyes, night glare (starbursts or halos that are most noticeable when you’re viewing lights at night). These side effects tend to disappear within days and for some of them in the weeks after surgery.
If you experience other side effects that do not conform to what is described, do not hesitate to contact your eye doctor.
Laser eye surgery offers numerous benefits and can dramatically improve your quality of life. However, complications can sometimes occur during or after laser surgery.
– Infection: any kind of surgical gesture may promote infections whatever the surgical precautions are taken with aseptic. Some virulent organisms are part of our immediate environment. For example when a patient is taken out of the operating theatre into the waiting room can be at risk of an infection. However, antibiotics are effective, and the laser is done externally. Also if an infection occurs, it would be superficial and often controllable by antibiotic. However, it is recommended to be extremely vigilant in the first days after procedure. Any abnormal symptoms (redness, pain, blurred) should be subject for consultation. It is of course recommended to avoid all activities increasing the risk of infection such as swimming pool, bikes, horseback riding, etc. and this for three to four days after surgery.
– Flap complications. The LASIK procedure involves the creation of a thin hinged flap on the front surface of the cornea. This is lifted during surgery for laser reshaping of the eye. The flap is then replaced to form a natural bandage. If the LASIK flap is not made correctly, it may fail to adhere properly to the eye’s surface or microscopic wrinkles called striae (STRIE-ee) could develop in the flap. In this case it is recommended to wait 2 months to restart the surgery.
This complication does not cause (except in exceptional cases) changes in visual acuity.
– Fault devices: unfortunately any mechanical equipment such as laser is susceptible to break down. If this happens during the intervention it is not a problem. You can restart and continue your intervention few days later and get the same excellent result.
Patients should avoid wearing contact lenses before surgery because they distort the cornea.
– 48 hours for soft contact lenses.
– 8 to 10 days for rigid gas permeable lenses
You may begin driving as soon as you see well enough; excluding the day you had LASIK performed.
It is recommended not to rub the eye and do not engage in activities that can promote infection: motorcycle; riding, swimming, etc. Sport can be practiced 3 days after treatment.
One day after surgery you may resume wearing eyelid makeup. 3 days after full make up can be applied.
Except rare cases, you can usually resume your professional activities from the next day as well as travelling etc
It is recommended to wear sunglasses few days after the surgery as Lasik can increase sensitivity to the sun.
– Use the drops prescribed by your surgeon.
– Do not go to the pool or ride a bike for three days.
– Wear protective glasses to avoid the risk of conjunctivitis for 3 to 6 months.
– Wait a few days or months before resuming the practice of sport (depending on the sport practiced).
– Avoid eye makeup for a few days.
– Get an every year check-up that include fundoscopy and eyestrain test.
Some patients may have high myopia associated with other eye conditions that limit vision. The treatment allows correcting the visual defect and gets rid of the glasses or lenses but does not treat other eye conditions.
The aim of the operation is to get rid of glasses or contacts lenses. Postoperative uncorrected vision will usually be comparable to preoperative corrected vision. In 5 to 10 % of cases, vision may be slightly different.
An enhancement is a follow-up procedure that sometimes is performed if the outcome of your original vision correction surgery is unsatisfactory (overcorrection or undercorrection). These adjustments are needed in 1 to 5 % of cases and are done usually few days or few months after the surgery.
Patients may have discomfort working at a computer screen, especially in cases where only one eye has been operated. That’s why you should allow at least 24 to 48 hours before using a computer.
If you must use your PC then remember to use the drops provided.
LASIK and other types of laser eye surgery have a very high success rates. They are designed to treat myopia, hyperopia and astigmatism, and can allow you to live without glasses or contact lenses. However, it may happen that the treatment is incomplete (meaning it was done up to 90%). In this case the problem can be resolved additional “enhancement” surgery.
In very rare cases, some complications may arise (major inflammatory or infection problem) and cause slight corneal opacity and visual loss. This can be corrected by a corneal transplant that will restore the transparency of the cornea.
