LASIK (Laser-Assisted in Situ Keratomileusis) surgery:Optical Evolution

Refractive surgery improves vision by reshaping the cornea. Using a laser, a thin flap is made in the cornea to access the underlying tissue. Another laser then corrects refractive errors such as near and farsightedness, and astigmatism by reshaping the corneal tissue. The flap is repositioned, and the cornea naturally adheres without suturing.

Preoperative Evaluation

  • Comprehensive eye examination to assess overall eye health and determine candidacy for LASIK.
  • Measurement of refractive error, corneal thickness, pupil size, and tear film quality.
  • Discussion of expectations, risks, benefits, and alternative treatment options.


  • Rapid visual recovery: Most patients experience improved vision within a day or two after surgery.
  • Reduced dependence on glasses: Many patients achieve clear vision without the need for corrective eyewear.
  • Convenience: Eliminates the hassle of cleaning, storing, and replacing contact lenses.
  • Improved quality of life: Enhanced vision can increase confidence and freedom in daily activities.

Risks and Complications

After LASIK surgery, possible issues include dry eyes, trouble seeing clearly, needing more treatment, flap problems, and rare infections.

Postoperative Care

  • Use prescribed eye drops to promote healing and reduce the risk of infection.
  • To prevent moving the corneal flap, it's important not to rub or touch your eyes.
  • Temporary restrictions on activities such as swimming, contact sports, and using eye makeup.
  • After surgery, it's essential to have follow-up appointments with the surgeon to check and discuss about you're healing

LASIK surgery is a safe and effective procedure for correcting refractive errors and improving vision. With careful preoperative evaluation, meticulous surgical technique, and appropriate postoperative care, LASIK can provide lasting benefits and enhance the quality of life for eligible candidates. However, weighing the potential risks and benefits and discussing any concerns with an experienced eye care professional before undergoing LASIK surgery is essential.
