What are the limits for laser vision correction?
What is the most suitable age for excimer laser vision correction?
The most suitable age for laser vision correction is between 18-45 years old. It is not recommended before 18 because at this age the refraction may change as the whole body grows, including the eyeball. After 45, physicians keep warning patients that laser correction does not safeguard against the possible occurrence of age-related farsightedness (presbyopia).
Laser correction is possible both under 18 and after 45 years old, but it is a strictly individual decision, which is made by the doctor.
Are there any contraindications to excimer laser correction?
There are few contraindications to laser vision correction. They include eye diseases such as cataract, glaucoma, retinal pathology, and general diseases (tuberculosis, diabetes, inflammatory diseases, tumors, infections). Laser correction is not recommended for pregnant and lactating women.
How long has laser correction been known?
Laser vision correction was first performed in 1985 and since then it has proven to be reliable and effective.
How many laser corrections have been done worldwide?
Currently, excimer laser correction is used in medical centers and clinics in 45 countries all over the world. Over 10 million vision corrections have been performed worldwide over the last 10 years.
Can my vision worsen after correction?
The result of laser correction is unchanged. This fact has been proven over time. Indeed, vision correction underwent multistage clinical tests before its full-scale implementation in ophthalmological clinics around the world. Thus far no cases of eyesight impairment due to laser correction have been registered. However, doctors warn all patients that worsening of vision is possible in case of age-related changes in the organism after 45-50 and development of age-related farsightedness (presbyopia).
How painless is excimer laser correction?
The procedure is absolutely painless and is done under local droplet anesthesia.
How long must I be hospitalized after laser vision correction?
There is no need for hospitalization. The laser vision correction is performed in a single day, i.e., without hospitalization. It takes 10-15 minutes. The patient shall spend only 1.5-2 hours in the clinic including preoperative preparation and obligatory post-surgery check-up and thus can return home the same day.
What happens if the power goes out during laser correction?
If this happens (which is highly unlikely), the laser system’s power supply will be reconnected to an uninterruptible power supply. Not only the devices but also the system for providing a safe environment (dehumidifier and air conditioners with microfilters, etc.) will be connected to such UPS. This allows for a fully-fledged correction on both eyes, without any breach of technology.
Can I do sports after laser correction?
Yes, you can! You can enjoy your ordinary life after laser vision correction, just like before. There are no limitations for physical and vision activities after the laser correction. Femto-LASIK eye surgery is an effective way to restore eyesight for people who experience maximal strain such as test pilots, alpinists, stuntmen, and even astronauts.
How long before I can work at a computer after laser vision correction?
It is possible to work at a computer 1 to 2 days after the laser vision correction. Depending on individual characteristics, many patients can work at a computer the very next day without any restrictions.
Why should I undergo diagnostics before correction?
Only diagnostics can determine the necessity for laser correction. An eye exam is required to help the doctor not only to make sure in the expediency of laser correction but also to offer individual treatment options for the particular patient and to estimate the parameters for the future vision correction. Laser vision correction can be performed on the same day right after a comprehensive eye exam. The only condition is for you to agree on this point when scheduling your visit by phone.
Is laser correction safe?
The benefits of laser correction consist of its predictability, safety, and non-traumatic effects. Laser correction underwent multi-phase clinical trials before it was used in ophthalmology centers and clinics. Long-term observations have shown that the excimer laser causes no disturbance because it affects only one of the refractive media, the cornea, and the exposure depth is strictly limited.
All excimer lasers operate in the same wavelength range, in pulsed mode. The temperature in the tissue vaporization zone hardly rises (less than 5-6 °C) due to short-term exposure. The laser removes a layer of 0.25 µm thick (about 1/500 of the thickness of a human hair) with each pulse. Such precision allows achieving a perfect result of laser vision correction and has no effect on internal tissues.
In addition, you can be sure of safety because the intensity of the laser exposure is controlled by the computer, and the system of tracking the patient’s eyes during the operation provides the most accurate centering of the vaporization zone.
Do I have to restrict my physical activity?
No doubt, you should have a more relaxed lifestyle on the first day after laser vision correction, but it does not mean that you will have to restrict your physical activities later on. You will be able to continue your active life after 1-2 days and go back to sports.
Will there be any restrictions afterward?
The recovery period after laser vision correction is minimal. Slight discomfort after the correction disappears in 30 to 40 minutes, and the final recovery of visual functions occurs within a few days. Immediate restrictions are minor and mostly concern the hygiene procedures (going to the swimming pool, sauna, cosmetics use). There are no restrictions later on.
May I need a second correction?
In some extremely complex cases, a second correction may be necessary, but in most cases, it is not required.
What happens if the laser “swipes”?
The laser cannot “swipe” during the treatment process. Firstly, the eye is fixed with a special vacuum ring, and the head is secured with a vacuum cushion. Secondly, the laser at Eximer Ophthalmology Clinic is equipped with a special eye-tracking system, so the laser beam cannot go the wrong way.
