SMILE Eye Surgery: Overview
SMILE (Small Incision Lenticule Extraction) is a minimally invasive laser procedure designed to correct nearsightedness and astigmatism. By creating and removing a small disc of corneal tissue, known as a lenticule, through a tiny incision, the surgery reshapes the cornea and improves vision, potentially reducing or eliminating the need for glasses or contact lenses.
Eligibility and Benefits
SMILE surgery is suitable for individuals aged 22 or older with a stable prescription. Candidates should have healthy corneas and prescriptions ranging from -1.0 to -10.0 diopters for nearsightedness and up to 3 diopters for astigmatism. The procedure offers several advantages over LASIK, including quicker healing, reduced risk of dry eyes, and minimal nerve or tissue damage. It’s also better suited for those with higher prescriptions or active lifestyles due to the absence of a corneal flap.
Procedure and Recovery
The SMILE procedure is quick, lasting only a few minutes per eye, with the laser operation taking about 30 seconds. Recovery is rapid, allowing most patients to resume regular activities within one or two days. Vision improvement is noticeable shortly after surgery and continues to enhance over weeks. Patients are advised to avoid strenuous activities and water exposure during the initial recovery period.
Risks and Limitations
While SMILE is highly effective, potential risks include halos, glare, and dry eyes. The procedure is limited to treating nearsightedness and astigmatism and may not be suitable for individuals with other vision issues like farsightedness. Additionally, finding a surgeon experienced in SMILE may be more challenging than for LASIK due to its relative newness.
Conclusion
SMILE eye surgery has a high success rate, with 99% of patients achieving at least 20/40 vision and 88% achieving 20/20 vision within six months. If you experience severe pain, vision loss, or signs of infection after surgery, contact your healthcare provider immediately. Speak with your eye care professional to determine if SMILE surgery is the right choice for your vision correction needs.
