Lasik Surgery

LASIK (Laser-Assisted In Situ Keratomileusis) is a popular and effective laser eye surgery used to correct refractive vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The procedure reshapes the cornea — the clear front part of the eye — so that light entering the eye is properly focused onto the retina, resulting in clearer vision.

Symptoms:

Before considering LASIK, individuals may experience:

• Blurred or distorted vision
• Difficulty seeing at night
• Eye strain or fatigue
• Headaches due to eye stress
• Frequent changes in glasses or contact lens prescription

These symptoms often indicate a refractive error, which can be evaluated by an eye care specialist.

Causes:

The need for LASIK arises from refractive errors, which are typically caused by imperfections in the shape of the cornea or the length of the eyeball. Genetics plays a significant role in determining refractive errors. Prolonged use of digital screens, inadequate lighting, and excessive near work may worsen these conditions over time. LASIK is considered when individuals want to reduce or eliminate dependence on glasses or contact lenses.

Treatment:

LASIK is a quick, outpatient procedure typically completed within 15 minutes for both eyes. After applying numbing eye drops, a thin flap is created on the cornea using a microkeratome or femtosecond laser. The underlying corneal tissue is then reshaped using an excimer laser, and the flap is repositioned without stitches.

Recovery is rapid, with most patients noticing improved vision within 24–48 hours. Temporary side effects may include dry eyes, glare, halos, or light sensitivity, which usually subside within a few weeks. Regular follow-up is essential to monitor healing and vision stability.

LASIK is safe and highly successful when performed on suitable candidates. However, a thorough preoperative evaluation is necessary to ensure eligibility and achieve optimal results.
