FAQs

To be sure that eye is proper to laser operation there should be 2 factors: The first is the glasses number of the eye should be suitable (myopia between -1.0 to –10.0 , hyperopia +1.0 to +5.0 , and astigmatism+/-1.0 to +/- 5.0).
The second factor is the structure of the eye -especially cornea – should be proper, regarding topography, shape and thickness of the cornea, without having any eye disease that may effect laser outcome, like cataract, glaucoma and retinal diseases.
So.. a detail test including corneal topography and thickness (pentacam test) should be performed before laser operation.

To decrease the possibility of the regression of the refractive problem after laser operation to the minimal level , we should prefer to perform the latest laser technology which is Intralasik (Femtolasik).

In cases of hyperopia and astigmatism the possibility of some regression is higher after lasik. Whereas if we perform Femtolasik, possibility of regression is almost absent.

Patient will not need any kind of general or local anesthesia. Drops are enough for complete anesthesia of the eye so that patient will not have any pain . Anyhow, the operation will not last for more than 10 minutes.

If the eye’s refractive number, and structure are suitable, and if we execute the latest Femtolasik laser technology, the side effect possibility will be less than 1/1000 . So tests before laser operation are very important.

All laser operations of all techniques are not handicap for any future eye operation, like cataract (that mostly occurs elderly) , glaucoma or even retinal surgeries .

Actually, what most people call excimer laser (not lasik of femtolasik) is the PRK laser operation, in which laser is applied superficially onto the cornea without lifting a corneal layer (flap). But this will create some pain and bothering that may last for 3 days. This is the oldest laser technique and it is mostly now not preferred because of the pain and the haze that may be created.

To get rid of such problems, lasik and Intralasik techniques had been developed, in which a corneal flap is lifted up and then laser rays are applied beneath it. So, patient can return to normal life directly in the next day.

In lasik operation the corneal flap is lifted up by a special knife which is inserted inside a machine called microkeratome. However, in femtolasik the corneal flap is lifted up by the femto laser which can control very precisely the thickness and shape of the lifted corneal flap. That’s why femtolasik is more precise, safer and much better than lasik.

In lasik and femtolasik operations nothing is put inside the eye during the opertation. However, in PRK operation a contact lens is put to protect the eye and decrease the pain for 3-4 days.
