Refractive Surgery: FAQs
Which procedure is the best?
There is no universally accepted best method for correcting refractive anomalies. Recommended methods depending on the dioptre: 0.00 to -7.00 LASIK, PRK, LASEK and EPILASIK -7.00 to -12.00 LASIK > -12.00 Implantation of intraocular lenses > -16.00 Clear lens extraction with / without implanting IOL 0.00 to +6.00 LASIK Talk to your ophthalmologist about your needs and lifestyle to help you determine correction method that will be best for you.
Who is not suitable for refractive surgery?
People younger than 18 and older than 60 years People with unstable diopter (frequent changes diopter past year) People with keratoconus People with dry eye (Schirmer test> 7mm) People who have other eye disease (glaucoma, uveitis, retinopathy ..) Pregnant women Immunocompromised patients People with diabetes Active athletes
What shall I do before surgery?
Before surgery is necessary to do a detailed pre-surgical examination: Visual acuity exam with help of testing glasses and phoropter Measurement of intraocular pressure Examination of anterior eye structure and eye ground with ophthalmoscope Tear film test (Schirmer test) Refractometry on narrow and dilated pupils Corneal topography Assessment of the strength of the natural lens and the axial length of the eye (IOL master) Depending on the findings it may be necessary to do the additional tests that will be recommend by your ophthalmologist. During the preoperative preparation of patients who use contact lenses (GP, soft, toric) it is necessary that the contacts are not used specific number of days in order to obtain an adequate finding of corneal topography. Your ophthalmologist may also require that you do not use to some products (make-up, creams, lotions, etc.).
What does the procedure look like?
Each of these procedures are performed under local topical (eye drop) anaesthesia, which takes no more than 10 minutes per eye and is completely painless. During the intervention, the patient lies under the operating microscope with a laser and follows the instructions from the surgeon. Its is necessary that the patient is relaxed during laser intervention and looks at the bright green laser, but even if the eye moves quickly Allegretto Wave® Eye-Q Laser has integrated highly sophisticated eye tracker system that tracks eye movements at a rate of 400 movements per seconds.
What to do after the procedure?
To protect your cornea until healing, an ophthalmologist can you put a contact lens and recommend wearing a protective shield at night. It is normal to feel a burning sensation, scratching, dryness of the eye. This reaction usually disappears within a few hours. After surgery, you will stay in the clinic for some time (approximately 30 minutes) in order to follow an early postoperative period. Your doctor will give you further instructions, eye drops to the eye to heal and soften the burning sensation, itching, dryness, etc.
According to research by the European Society of Refractive Surgery (ESCRS) 98% of patients who have undergone laser vision correction would recommend this method to others. More than 95% of the people who underwent refractive surgery can pass the standard driving test without glasses or contact lenses. Thanks to this method, more than 30 million people worldwide have so far taken off their glasses and contact lenses. Laser vision correction is the best accepted and most successful intervention on the human body.
