Select any of the following FAQs from our patients and check the answers. If your doubts are not solved please use the contact form below to get in touch with us.
Refractive errors (myopia, hyperopia, astigmatism) can only be corrected when the patient’s prescription is stabilised, which occurs around the age of 20.
Yes, any of the procedures currently used (laser and lens implants) allow the simultaneous correction of both errors.
The eye must remains as stable as possible during surgery, therefore patients lie on a treatment table with their eyes fixed on a red light on the Excimer Laser machine.
A safety device called eye tracker compensates for involuntary eye movements following up the eye at milliseconds intervals and adjusting the direction of the laser pulses. In case of sudden movements the safety system fully stops the treatment.
It is a quick procedure. Patients remain in the surgery room for 15-20 minutes on average. Just a few seconds of that time are used for the application of the Excimer Laser. The remaining time is used to prepare the patient’s eye for surgery.
Refractive surgery procedures are carried out using topical (local) anaesthetics (eye drops). Patients do not experience any pain during the operation.
LASIK and PRK procedures have very simple post-operative processes which require only eye drops and artificial tears.
After surgery it is recommended to rest at least for 24 hours. Most work activities can be resumed after 48 hours. Patients must wait at least a week to resume any sport activity.
During the pre-op check up, our medical team will examine the condition of the cornea, namely corneal width and number of dioptres to be corrected. Laser treatment vaporises corneal tissue. The amount of extracted tissue is proportional to the number of dioptres to be treated. Intraocular lens implants may be considered if prescription is very high.
