In order to give you an answer on the safe feasibility of a refractive surgery, it is necessary to proceed with focused tests and exclude potential risks. To go ahead with the pre-operative examination it is necessary to suspend wearing contact lenses at least 15 days earlier.
It is the Femtosecond laser. This laser has great potentialities in the ophthalmic field, because it replaces the mechanical equipment formerly used, increasing the surgery precision and reducing the operation risk.
Usually the operation takes from 5 to 7 minutes per treatment (per eye). The difference in time is caused by the technique performed and by the vision disorder to cure.
Not suitability of the eye to undergo these treatments, eye pathologies and strabismus. Each patient has to follow a pre-operative examination and in most cases it is possible to go ahead with the surgery after an appropriate treatment.
Pre-operative examination is necessary even if the patient’s eyes are in good health: map of the cornea, corneal thickness, etc to guarantee the suitability for the treatment.The international guidelines are detailed and strict, and clearly describe the functional and anatomical parameters that an eye needs to be suitable for the treatment.
In most cases, the operation completely succeeds. Thanks to the latest equipment and to the most advanced expertise, the risks of a partial negative result are extremely low. However it is possible to carry out a second treatment.
Potentially all the vision disorders can be cured. The differences and the potential non-suitability depend on the seriousness of the vision disorder in relation to the structure of the eye that has to be treated.
Modern lasers are equipped with a new technology called eye tracking system, which can follow the eye movements during the operation. This technology optimises the ablation and prevents the treatment from beingnot perfectly centred, cancelling the potential errors due toa bad cooperation of the patient.
No, a local anaesthetic is sufficient: a few drops of an anaesthetic eye-drop.
No, it won’t. The patient will feel just a slight pressure on the eye during the first stage of the treatment, but no pain at all.
The operation can be both unilateralor bilateral. The surgeon decides it case by case to optimise time and results.
This is a problem we noticed in the past. Nowadays the lasers and the technologies have extremely improved and the patients that notice this kind of problem are a very low percentage.
The Femtosecond laser technique allows to go back to your everyday activities even the day after the operation. Driving is possible as well, without wearingglasses or contact lenses. Sports activities are possible too, except for particular sports that involve physical contact (boxing, judo, rugby or other sports that involve violent impacts). It will be possible to go back to these particular sports approximately 2 months after the operation, after the authorization of your ophthalmologist. Swimming must be suspended for approximately 1 month for hygienic reasons.
There is a variety of solutions that doesn’t involve the use of the laser: the main option is the implant of intraocular lenses called phakic, a reversible technique recommended in case of serious myopia that cannot be treated with the laser.
The treatment does not increase in any way the risks for your eyes health. There are international guidelines that specify when and how it is possible to treat an eye without compromising its efficiency and health.
