LASIK

(Laser-Assisted In Situ Keratomileusis)

LASIK (Laser-Assisted In Situ Keratomileusis) is a laser vision correction procedure that reshapes the cornea to correct refractive errors such as nearsightedness, farsightedness, and astigmatism.

You may be a good candidate if you:

  • Are at least 18 years old
  • Have a stable prescription for at least one year
  • Have healthy eyes (no infections, significant dryness, or corneal diseases)
  • Are not pregnant or breastfeeding

Your eye doctor will perform a thorough evaluation to confirm eligibility.

The surgery itself takes about 10-15 minutes for both eyes, and the laser treatment lasts only seconds.

Most patients notice clearer vision within 24 hours. You can usually return to work and daily activities in 1–2 days, with full healing over a few weeks.

Yes, LASIK permanently reshapes the cornea. However, natural changes in the eyes with age (like presbyopia or cataracts) may still occur later in life.

Mild dryness, glare, or halos at night may occur temporarily but usually improve within weeks. Serious complications are rare, especially with advanced technology like the Alcon WaveLight® EX500.

Most patients achieve 20/20 vision or better without glasses. Some may still need glasses for fine detail or reading as they age.

LASIK is one of the most studied and trusted elective surgeries in the world, with a high success and satisfaction rate.

No, LASIK is not painful. Numbing eye drops are used before the procedure. You may feel mild pressure during the surgery and some temporary discomfort, dryness, or burning afterward.

PRK

(Photorefractive Keratectomy)

PRK (Photorefractive Keratectomy) is a type of laser vision correction. Like LASIK, it reshapes the cornea with a laser to correct nearsightedness, farsightedness, and astigmatism. The difference is that no flap is created — instead, the thin surface layer of the cornea is gently removed and allowed to regrow naturally.

  • Have thin corneas and are not suitable for LASIK
  • Lead an active lifestyle with higher risk of eye trauma (athletes, military, etc.)
  • Want excellent long-term vision correction without a corneal flap
  • During the procedure, numbing drops keep you comfortable. After surgery, mild discomfort or scratchy sensation can occur for a few days while the corneal surface heals.

  • The surface layer of the cornea (epithelium) heals in about 3–5 days.
  • Clear vision improves gradually, with most patients seeing well in 1–2 weeks.
  • Full visual clarity may take several weeks to a few months.

Yes. PRK permanently reshapes the cornea to correct your vision. However, natural age-related changes (like presbyopia or cataracts) may still occur later in life.

Both are safe and effective. PRK has a longer recovery time, but it avoids the creation of a flap, making it better for certain patients (e.g., thin corneas, high-impact lifestyles).

Temporary side effects may include mild pain, light sensitivity, glare, or halos at night. These usually improve as the eye heals. Serious complications are rare.

Most patients achieve 20/20 vision or better without glasses. Some may still need glasses for fine detail or reading as they age.

PRK usually takes 10–15 minutes per eye

ICL

(Implantable Collamer Lens)

ICL (Implantable Collamer Lens) surgery is a vision correction procedure where a soft, biocompatible lens is placed inside the eye to correct vision. Unlike LASIK or PRK, no corneal tissue is removed. The lens works like a permanent contact lens that you never have to take out.

 

  • Have high levels of nearsightedness (beyond LASIK limits)
  • Have thin or irregular corneas not suitable for LASIK/PRK
  • Suffer from dry eyes that make LASIK difficult
  • Are looking for a reversible vision correction option

No. Numbing eye drops are used, so the procedure is comfortable. Most patients only feel mild pressure during surgery

Most patients notice clearer vision almost immediately after surgery. Recovery is typically quick, with many resuming normal activities within a few days.

Yes — the lens can stay in place for life. However, one unique benefit of ICL is that it’s removable or replaceable if needed, making it flexible for future vision changes.

ICL has an excellent safety record worldwide. The lens is made of Collamer®, a biocompatible material that works in harmony with your natural eye.

No. You won’t see or feel the lens once it’s in place. It remains invisible and works naturally with your vision

  • ICL: No corneal tissue removal, ideal for high prescriptions and thin corneas, reversible.
  • LASIK/PRK: Permanent reshaping of the cornea, quicker visual recovery (LASIK), or no flap (PRK).
    All three deliver excellent results, but the right option depends on your eye health and lifestyle.

ICL surgery usually takes about 20–30 minutes per eye.
