The result of laser refractive surgery depends on several factors:
- equipment that determines the accuracy of correction, and the likelihood of complications, and the rehabilitation period;
- doctor’s qualifications – only a competent ophthalmologist will be able to correctly interpret diagnostic data and configure the system before surgery;
- compliance of the patient with certain criteria.
Ophthalmologists have prepared a checklist by which you can check if laser correction is right for you.
Ideal patient criteria for LASIK
- Healthy eyes. Dry eye syndrome, conjunctivitis, blepharitis – all these conditions affect how the eye reacts to surgery and how long it takes to recover from it.
- Sufficient corneal thickness. Previously, laser correction was not available to patients with thin corneas . The modern TENEO 317 ™ laser system, which is used in our clinic, bypasses this limitation: the laser removes a smaller layer of the cornea and very delicately acts on the corneal stroma.
- Pupil size. If it is too large, the risk of side effects increases: postoperative halo, deterioration of night vision.
- Refractive error value. With high values of hyperopia, myopia and astigmatism, the result of the operation is less predictable.
- Age. Although there is no upper age limit for laser correction, older patients are at higher risk of some complications. So, postmenopausal women are more likely to develop dry eye syndrome after surgery.
- Stable vision throughout the year.
- General health. There are a number of autoimmune, degenerative diseases that are considered contraindications to LASIK. Some of them are absolute, some only increase the risk of undesirable consequences and affect the result of the correction. Only an ophthalmologist, using all the information about the state of the optical system and your health, can tell whether laser surgery is right for you.
