About Lasik
LASIK (Laser-Assisted in Situ Keratomileusis) is a popular laser eye surgery used to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It reshapes the cornea to improve how light is focused on the retina, reducing or eliminating the need for glasses or contact lenses. The procedure is quick, usually painless, and has a short recovery time.

What is Lasik Surgery
LASIK (Laser-Assisted In Situ Keratomileusis) surgery is a popular and advanced surgical procedure used to fix refractive vision problems like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. LASIK surgery aims to enhance vision by reshaping the cornea (clear front surface of the eye) so that light entering the eye is correctly focused onto the retina.
LASIK is generally an outpatient procedure. Also, both eyes can often be treated during the same session. It is conducted using topical anesthesia (eye drops), and the entire procedure usually takes 10 to 15 minutes per eye.
LASIK is a laser vision correction procedure that reshapes the cornea to improve focus and correct common vision issues like nearsightedness, farsightedness, and astigmatism.
- Traditional LASIK: This is the classic LASIK procedure where a microkeratome or a femtosecond laser forms a thin corneal flap, which is lifted to allow the laser to reshape the cornea. After the cornea is reshaped, the flap is repositioned.
- Bladeless LASIK: Also known as “all-laser LASIK” or “blade-free lasik,” this procedure uses a femtosecond laser to create the thin corneal flap instead of a microkeratome. Then, an excimer laser is utilized to reshape the underlying corneal tissue to correct your vision. The flap is then repositioned to its original position. Bladeless LASIK offers more precision and customization during the flap creation
LASIK is FDA-approved and widely considered safe when performed on the right candidates by experienced surgeons. A full pre-operative evaluation is essential to ensure you're a good candidate.
- Nearsightedness (Myopia): Myopia occurs when the eye is too long or the cornea is overly curved, causing light to concentrate in front of the retina instead of directly on it. As a result, distant objects seem blurry, while close-up objects are seen more clearly.
- Farsightedness (Hyperopia): Hyperopia is the opposite of myopia. It occurs when the eye is too short or the cornea is too flat, causing light to concentrate behind the retina. People with hyperopia usually have better distance vision but may struggle with close-up tasks.

You may be a good candidate if you’re over 18, have a stable prescription for at least 1–2 years, have healthy eyes, and no active eye diseases. A detailed eye exam will determine your eligibility.
- Stop wearing contact lenses for a few days or weeks before evaluation
- Avoid makeup, lotions, and perfume on the day of surgery
- Arrange for someone to drive you home after the procedure
A comprehensive eye exam is performed, including corneal mapping, pupil measurement, dry eye testing, and other diagnostics to ensure LASIK is safe and appropriate for your eyes.

No. Your eyes will be numbed with anesthetic drops. Most people feel only mild pressure during the procedure and describe post-surgery discomfort as a gritty or dry-eye sensation that fades within hours.
You may feel slight pressure or a sensation of something touching your eye during the procedure. Afterward, it may feel like there’s an eyelash in your eye — this typically goes away within a few hours.
Most patients see clearly within 24–48 hours. Light activity can resume the next day, but avoid swimming, eye rubbing, and intense physical activity for at least a week.
In most cases, LASIK provides permanent vision correction. If your vision changes due to age or other natural causes, a follow-up treatment may be an option, though it's rarely needed.
Enhancements are rare but possible. If vision changes significantly years later, you may qualify for a touch-up procedure.
Yes, LASIK can correct nearsightedness, farsightedness, and astigmatism. For age-related near vision loss (presbyopia), monovision LASIK or other solutions may be recommended.
Most patients no longer need glasses or contacts for distance vision. However, reading glasses may still be needed after age 40 due to presbyopia.
Serious complications are extremely rare. LASIK has an excellent safety record, and the risk of blindness is exceptionally low when performed by a skilled surgeon.
Temporary side effects may include dry eyes, glare, halos, or sensitivity to light. These usually improve within weeks or months.
Are You Experiencing Any of These Symptoms?
If you’re struggling with blurry vision, frequent headaches, or frustration with glasses or contact lenses, LASIK surgery might be the solution you’ve been searching for. Common symptoms and conditions that can be treated with LASIK surgery include:
Blurry Vision: Difficulty seeing clearly at various distances, especially when driving or reading.
Frequent Changes in Prescription: Constantly needing new glasses or contact lenses due to worsening vision.
Dependence on Glasses or Contacts: Tired of the hassle and limitations of glasses or contact lenses, particularly for sports or daily activities.
Night Vision Problems: Difficulty seeing at night, experiencing glare, halos, or starbursts around lights.
Dry or Irritated Eyes: Chronic discomfort caused by contact lenses or the need for frequent eye drops.
Astigmatism: Distorted or blurred vision caused by an irregularly shaped cornea.
If any of these symptoms sound familiar, LASIK surgery could be the right step toward clearer, more comfortable vision.
