Myopia Surgery: Everything You Need To Know

Myopia surgery, also called refractive surgery, is indicated for the correction of the patient’s degree and may not require eyeglasses and contact lenses. The exact surgical procedure can also correct, at once, other refractive problems, such as farsightedness and astigmatism.

Understand the complete surgery process for ophthalmoplegia (กล้ามเนื้อตาอ่อนแรง which is the term in Thai), from the indication of the operation by the ophthalmologist or the patient’s manifestation of their desire to operate to post-operative care and recovery. The procedure is indicated precisely to correct so-called vices or refractive errors, enabling healthy vision without the need for glasses or contact lenses.

What Do I Need To Do Before Myopia Surgery?

Before the surgery for myopia, the patient must undergo preoperative exams so that the individual’s eye health is known and there are no problems that may pose any risk to the surgery. The necessary exams are usually eye fundus, intraocular pressure measurement, corneal topography, degree evaluation, and others. With all this, the ophthalmologist will know if the patient is fit for the procedure and if surgery can be indicated.

Some factors can prevent myopia surgery from being done for the patient’s safety. Among them is keratoconus, a condition that causes the cornea to change shape; glaucoma, which is related to intraocular pressure; diabetes, which hinders the healing process of the operated cornea; the cataract; systemic autoimmune diseases; amblyopia (lazy eye); ocular herpes; and also, the patient’s age, which must be over 18 years. Contrary to popular belief, degree instability does not impede as myopia progresses less in already operated eyes.


Wearing glasses or contact lenses can be a thing of the past for people with nearsightedness, farsightedness, or astigmatism. Refractive surgery is a reality, correcting these problems (refraction errors). It sounds like a dream. But a lot of people still have several doubts about the procedure.
