Technological advances in recent decades have positioned laser surgery as an increasingly widespread option among patients who want to correct visual refractive defects such as myopia or astigmatism.
In fact, in a good number of cases, they have replaced the usual treatments in this regard, such as the use of contact lenses or glasses.
It increased efficiency, comfort, rapid postoperative period, and the fact that they focus on the cause of such refractive defects are some of the reasons that explain the increased demand for these procedures.
What Is Special About Laser Surgeries
Laser procedures favor a vital element when it comes to solutions for refractive defects: they prevent patients from relying on contact lenses or glasses; Moreover, they stop wearing them because surgery restores the anomaly in the area where it has occurred, and the use of these is no longer necessary.
Apart from that, they are short and straightforward interventions that do not involve a postoperative period that is too long. At best, patients resume their routine activities in a couple of days and without side effects or considerable risks.
And, above all, once the Eyes correction surgery [แก้ตา which is the term in Thai], they offer patients better quality results than those obtained with the use of glasses, whose frame can interfere with the field of vision.
Laser Surgeries: Disadvantages And Considerations
That does not mean that laser surgeries to correct defects of myopia, astigmatism, or farsightedness are free of risks or complications. Let’s see some comments and recommendations in this regard:
The most common side effects of this type of surgery are dry eyes, light halos, or reflexes, especially at night. In fact, in cases where vision is not stabilized, certain diopters are likely to reappear and should be treated later.
Despite the high degree of efficiency provided by the laser, some people require the use of glasses in the later stages of the intervention. This happens especially in patients with major refractive defects, to whom lenses are recommended for daily activities such as driving the car, reading, or simply protecting yourself from the sun’s rays.
In other cases, the problem lies in the difficulty of patients for an adaptation to their new visual condition. Some take weeks to assimilate the variations of their visual field, a situation that is usually somewhat annoying and uncomfortable.
