Refractive surgery corrects vision problems (nearsightedness, farsightedness, astigmatism, presbyopia) by reshaping the eye's cornea or replacing the natural lens, aiming to reduce or eliminate reliance on glasses or contacts. Common methods include LASIK, PRK, and SMILE, which use lasers to alter corneal shape, while others like ICLs (Implantable Collamer Lenses) or Refractive Lens Exchange involve implanting lenses. It's a safe, common procedure for visual freedom, though outcomes may vary. Decision should be taken after consulting an Eye Doctor.

Common Types of Refractive Surgery

• LASIK (Laser-Assisted In-Situ Keratomileusis) :

A flap is created on the cornea, the laser reshapes the underlying tissue, and the flap is repositioned.

• PRK (Photorefractive Keratectomy) :

The outer layer (epithelium) is removed, and the cornea is reshaped with a laser, with no flap created.

• SMILE (Small Incision Lenticule Extraction) :

A minimally invasive procedure where a small, laser-created disc (lenticule) is removed from within the cornea.

• Implantable Collamer Lenses (ICLs) / Phakic IOLs :

ICL surgery involves implanting a biocompatible lens inside the eye, providing permanent vision correction without reshaping the cornea. It is ideal for patients with thin corneas or extreme refractive errors, individuals seeking a reversible procedure, and those with dry eye concerns. ICL is gaining popularity as an excellent alternative to LASIK, offering superior vision quality and reversibility if needed.

• Refractive Lens Exchange (RLE) :

The eye's natural lens is replaced with an artificial intraocular lens (IOL).

Who is a Good Candidate ?

• Individuals with myopia, hyperopia, or astigmatism

• Must be at least 18 years of age.

• Must have a healthy cornea with sufficient thickness.

• Those wanting less dependence on glasses/contacts.

• People with stable vision and no significant eye diseases.

Benefits :

• Permanent correction of vision.

• Improved quality of life with reduced dependency on glasses and contact lenses.

• High success rate with rapid recovery.

• Customizable solutions for different eye conditions

Risks

• Temporary discomfort and dry eyes post-surgery

• Potential for glare, halos, or night vision disturbances

• Rare complications like under-correction, over-correction, or flap-related issues

Recovery

• Laser procedures (LASIK, PRK, SMILE) often involve quick recovery (days).

• Lens-based surgeries (ICLs, RLE) can take a few weeks for full healing.
