Refractive surgery
Refractive surgery refers to a group of surgical procedures designed to correct common vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The goal of refractive surgery is to reduce or eliminate the need for glasses or contact lenses by reshaping the cornea or implanting corrective lenses in the eye.
Types of Refractive Surgery
LASIK (Laser-Assisted In Situ Keratomileusis)
- A laser is used to create a thin flap on the cornea and reshape the underlying tissue to improve vision.
- Commonly used for myopia, hyperopia, and astigmatism.
- Quick recovery time with minimal discomfort.
PRK (Photorefractive Keratectomy)
- The outer layer of the cornea is removed, and the underlying corneal tissue is reshaped with a laser.
- Ideal for those with thin corneas or dry eyes.
SMILE (Small Incision Lenticule Extraction)
- A minimally invasive procedure where a small piece of corneal tissue is removed to reshape the cornea.
- Primarily used for myopia and astigmatism.
Implantable Collamer Lenses (ICL)
- A lens is implanted inside the eye to correct vision without altering the cornea.
- Suitable for patients with high prescriptions or thin corneas.
Refractive Lens Exchange (RLE)
- Similar to cataract surgery, where the eye’s natural lens is replaced with an artificial lens.
- Best for people with presbyopia or severe refractive errors.
Benefits of Refractive Surgery
- Reduces dependence on glasses or contact lenses.
- Provides long-term vision correction.
- Offers quick recovery times with most procedures.
Success Rate
Refractive surgery is highly successful, with over 90% of patients achieving 20/20 vision or better, depending on the procedure and individual factors.
Who is a Candidate?
- Adults aged 18 and above with stable vision prescriptions for at least a year.
- No significant eye diseases, such as cataracts or glaucoma.
Prevention of Vision Problems Post-Surgery
- Avoid excessive screen time or UV exposure.
- Regularly follow up with your eye doctor to monitor vision health.
Refractive surgery is a life-changing option for many, offering freedom from corrective lenses and improved quality of life when performed by an experienced surgeon.
