Normally, LASIK can correct nearsightedness plus astigmatism up to 1,200 D, provided the cornea is thick enough for the correction and there are no contraindications to the procedure.

If you have only presbyopia, LASIK is generally not recommended, but if presbyopia is combined with nearsightedness or astigmatism, the following refractive corrections are recommended:

• Completely correct the nearsightedness, called full correction. After the procedure, distance vision will be clear, but you will need reading glasses for near tasks.
• Leaving a slight amount of nearsightedness in one eye, called monovision. After the procedure, distance and near vision will be reasonably good, though not perfectly sharp, reducing dependence on reading glasses for 3–5 years. However, the prescription choice depends on individual preference, so an evaluation and trial with lenses is recommended before surgery.

For individuals under 18, doctors generally do not recommend LASIK because the prescription may still be unstable. The exception is those who need the procedure to qualify for military or police entrance exams; they may be evaluated and undergo LASIK.

• If you undergo Femto or SBK LASIK, take 1–2 days off work.
• If you undergo Trans PRK, take 5–7 days off work.

After the procedure, avoid exposing your eyes to smoke for 7 days. Therefore, steer clear of smoky foods for the time being—unless you order them to eat at home without grilling yourself, in which case you may eat as usual.

It is recommended to undergo a thorough evaluation, which involves several steps: measuring your prescription, assessing corneal thickness and curvature, and dilating the pupils for a detailed eye health check. Only then can the doctor determine the most suitable method to correct your vision.

Because every step of the evaluation is carried out in detail to ensure accuracy and precision, leading to good postoperative results.

LASIK is not recommended during pregnancy or while breastfeeding, unless you are breastfeeding, your menstrual cycle has returned to normal, and you can pump and discard breast milk for the first 7 days after the procedure (because medicated eye drops are used); in that case, LASIK can be performed.

After LASIK surgery, side effects can occur, but they are usually temporary. Over time, symptoms gradually improve and disappear on their own. Examples include initial eye irritation, seeing glare or halos at night or in low-light conditions, and dry eyes, which may persist for the first 3–6 months.
