SMILE (Small Incision Lenticule Extraction) is a modern refractive surgery designed to correct vision problems, including nearsightedness, farsightedness, and astigmatism. The procedure involves making a small incision in the cornea to remove a thin layer of corneal tissue, known as a lenticule, which reshapes the cornea and corrects refractive errors. Unlike LASIK, SMILE does not require a corneal flap, resulting in less disruption to the eye’s surface. Patients typically experience minimal discomfort and a quicker recovery time, making SMILE an appealing option for vision correction.
SMILE (Small Incision Lenticule Extraction) is generally well-tolerated, but some patients may experience symptoms post-procedure. Common symptoms include mild discomfort, dryness, and blurred vision immediately after surgery. Patients might also notice light sensitivity and halos around lights, especially at night. These symptoms typically resolve within a few days. If discomfort persists or worsens, it’s essential to consult your eye care provider for guidance and appropriate management.
Risk factors for Small Incision Lenticule Extraction (SMILE) include having thin or irregular corneas, which may affect the procedure’s success. Patients with high refractive errors or pre-existing eye conditions like glaucoma or severe dry eyes might not be ideal candidates. Additionally, those with unstable vision or certain autoimmune diseases may face increased risks, potentially complicating the healing process and final outcomes of the surgery.
SMILE (Small Incision Lenticule Extraction) surgery can be categorized into two main types: standard SMILE and customized SMILE. Standard SMILE corrects common refractive errors like nearsightedness and astigmatism by removing a specific amount of corneal tissue. Customized SMILE is tailored for more complex vision needs, offering personalized corrections based on the patient’s unique eye structure, providing improved precision and visual outcomes while minimizing recovery time.
The procedure uses a laser to create a lenticule, which is a thin layer of corneal tissue. This lenticule is then removed through a small incision, correcting vision.
Most patients experience minimal discomfort during and after the procedure. Local anesthesia is used to ensure a pain-free experience, with most individuals reporting only mild sensations.
SMILE offers several advantages, including minimal corneal disruption, quicker recovery time, less dryness, and a reduced risk of complications compared to traditional LASIK surgery.
Ideal candidates are typically aged 18 and older, have stable vision prescriptions, and have mild to moderate myopia or astigmatism. A thorough evaluation is necessary for eligibility.
Like any surgery, SMILE carries potential risks, including dry eyes, glare, halos, and undercorrection or overcorrection. Discussing these risks with your surgeon beforehand is crucial.
