Introduction
In general, astigmatism can be improved with laser treatment, but the effectiveness and suitability depend on individual eye conditions. A comprehensive eye examination is necessary before deciding on treatment to determine whether one meets the indications. After treatment, it is important to follow medical advice, avoid excessive eye use, and maintain good eye hygiene to promote recovery and sustain treatment outcomes.
In general, astigmatism can be improved with laser treatment, but the effectiveness and suitability depend on individual eye conditions. A detailed analysis is as follows:
Astigmatism is a vision problem caused by an irregularly shaped ocular refractive surface, which prevents light from focusing on a single point. Laser treatment corrects astigmatism by reshaping the cornea's anterior surface to adjust its refractive power, allowing light to focus accurately on the retina. This method is well-established and safe, effectively improving visual acuity and symptoms such as blurred or double vision, and is suitable for most eligible patients with astigmatism.
Patients should be between 18 and 50 years of age, with stable astigmatism for at least two years and an annual change of no more than 50 degrees. Additionally, corneal thickness must meet required standards, and patients must not have eye conditions such as keratoconus or keratitis, or systemic diseases like diabetes that may impair wound healing. For those who do not meet these criteria, undergoing treatment may lead to risks such as corneal damage.
Prior to deciding on treatment, a comprehensive eye examination is necessary to determine whether one meets the indications. After treatment, it is important to follow medical advice, avoid excessive eye use, and maintain good eye hygiene to promote recovery and sustain treatment outcomes.
