Refractive Eye Surgery

What Is Refractive Eye Surgery?

Refractive eye surgery refers to a group of surgical procedures designed to correct common vision problems such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. By reshaping the cornea or implanting special lenses, these treatments reduce or eliminate the need for glasses or contact lenses, providing patients with greater visual independence.

Who Can Benefit?

Refractive surgery may be suitable for individuals who:

Have stable glass or contact lens prescriptions
Are diagnosed with nearsightedness, farsightedness, or astigmatism
Want to reduce dependence on corrective eyewear
Are in good general and ocular health, without corneal diseases or uncontrolled conditions (like glaucoma or diabetes)
Are at least 18 years old with stable refraction for at least one year

Types of Refractive Surgery

LASIK (Laser-Assisted In Situ Keratomileusis)
The most common procedure, reshaping the cornea with an excimer laser to correct refractive errors.

PRK (Photorefractive Keratectomy)
A surface laser procedure suitable for patients with thinner corneas, reshaping without creating a corneal flap.

SMILE (Small Incision Lenticule Extraction)
A minimally invasive laser procedure that corrects myopia and astigmatism through a tiny incision.

Implantable Collamer Lenses (ICL)
Artificial lenses implanted inside the eye, especially for patients unsuitable for laser surgery.

Refractive Lens Exchange (RLE)
Replacement of the natural lens with an artificial intraocular lens, ideal for patients with presbyopia or early cataract.

Astigmatic Keratotomy (AK)
Small incisions in the cornea to correct mild to moderate astigmatism.

Benefits of Refractive Surgery

Reduced or eliminated dependence on glasses and contact lenses
Quick recovery and improved vision within days (depending on procedure)
Safe, effective, and highly predictable with modern technology
Long-term correction of refractive errors
Lifestyle convenience for sports, travel, and daily activities

Risks & Considerations

Although generally safe, refractive procedures may have risks :

Dry eyes or glare/halos around lights
Undercorrection or overcorrection requiring enhancement procedures
Infection or delayed healing (rare)
Flap-related complications in LASIK
Regression of effect over time in some patients
Need for reading glasses later in life (natural aging changes)

Postoperative Care & Recovery

Use prescribed eye drops to aid healing and reduce dryness
Avoid rubbing or pressing the eyes after surgery
Wear protective eyewear when outdoors or during sleep initially
Follow activity restrictions as advised (e.g., avoid swimming or heavy exercise temporarily)
Attend scheduled follow-up visits to monitor healing and visual outcomes
