Refractive surgery is designed to reduce or eliminate the need for glasses or contact lenses by reshaping the cornea (the clear front part of the eye) so that light focuses properly on the retina.
These procedures can correct common vision problems, including:
Myopia (Nearsightedness) – Difficulty seeing far away
Hyperopia (Farsightedness) – Difficulty seeing up close
Astigmatism – Blurred or distorted vision due to irregular corneal shape
Presbyopia – Age-related difficulty focusing up close
Types of Refractive Surgery
1. LASIK (Laser-Assisted In Situ Keratomileusis) The most common laser eye surgery. A thin flap is created on the cornea and lifted. A laser reshapes the underlying tissue to correct vision, and the flap is replaced. Benefits: Quick recovery, minimal discomfort, rapid vision improvement. Ideal for: Patients with stable prescriptions and healthy corneas.
2. PRK (Photorefractive Keratectomy) The corneal surface layer (epithelium) is removed instead of creating a flap. A laser reshapes the cornea directly, and the surface heals naturally within a few days. Benefits: Suitable for patients with thinner corneas. Recovery: Slightly longer healing time compared to LASIK.
3. SMILE (Small Incision Lenticule Extraction) A newer, minimally invasive laser procedure. A small “lenticule” (disc of corneal tissue) is created and removed through a tiny incision. Benefits: No flap creation, less dryness, faster recovery of corneal strength. Ideal for: Mild to moderate myopia (nearsightedness).
4. Implantable Collamer Lens (ICL) A soft, biocompatible lens is placed inside the eye, between the iris and natural lens. The natural lens is left in place. Benefits: Reversible procedure, suitable for patients who are not LASIK candidates (thin corneas or high prescriptions).
5. Refractive Lens Exchange (RLE) Similar to cataract surgery — the eye’s natural lens is replaced with an artificial intraocular lens (IOL). Ideal for: Patients over 40 with presbyopia or early lens changes. Benefits: Permanent correction and prevention of future cataract development.
6. Light Adjustable Lens (LAL) A special IOL implanted during cataract or lens replacement surgery. After surgery, the lens power is adjusted using a light treatment to fine-tune vision. Benefits: Offers the most precise, customized vision possible.
Choosing the Right Procedure
Our team of ophthalmologist will recommend the most suitable option based on:
Age and prescription stability
Corneal thickness and shape
Lifestyle and visual goals
Presence of dry eye or other eye conditions
Recovery and Aftercare
Most procedures are performed in an outpatient setting. Vision may be blurry for a few days, then gradually sharpens. Use prescribed eye drops and follow post-surgery instructions closely. Avoid rubbing your eyes and protect them from dust or impact.
Summary
Refractive surgery can provide long-term freedom from glasses or contact lenses. With today’s advanced laser and lens technologies, procedures are safe, accurate, and customized for each patient’s vision needs.
