Laser surgery has long been essential for correction of near-sightedness (myopia). Besides LASIK, there’s another option which is rather an advanced form of laser procedure known as SMILE. In the United States, SMILE laser eye surgery gained FDA approval back in 2016 and now performed confidently all around the world. Here’s all you need to know!
Small Incision Lenticule Extraction or SMILE is performed using a branded Carl Zeiss Meditec technology by the name VisuMax femtosecond laser. During the procedure, the surgeon introduces a micro, lens-shaped tissue bit (a Lenticule) within the cornea using this femtosecond laser which further creates a tiny arched incision on the corneal surface.
Surgeon would then extract the Lenticule through the cut and discards it thereby altering the corneal shape and rectifying near-sightedness. The incision heals in few days without any stitches after which sharper vision is restored. It has been proven that SMILE can correct almost -10.00 dioptres (D) of myopia where suitable candidates must be at-least 22 years old. They shouldn’t have astigmatism of more than -0.50 with a stable eyeglass prescription to at-least 12 months.
Research and candidates progress has revealed that visual acuity of SMILE is almost similar to LASIK in Dubai. Further studies proposed that almost 88-percent had their UCVA of 20/20 and even better with significant less risk of dry eye symptoms. There’re several reasons for this especially occurrence of the procedure which takes place within the cornea without actually introducing a larger corneal slit thus fewer nerves being affected.
This micro SMILE incision also enables the cornea to be more biomechanical stable whereas higher amount of corrected vision means follow-up surgery won’t be required. That being said, the need to wear eyeglasses is nearly zero-percent post-SMILE surgery with significantly less dehydration of the cornea.
Indeed packing many advantages, SMILE is only effective against near-sightedness whereas PRK and LASIK in Dubai also treat astigmatism and farsightedness to a significant extent. SMILE is unable to treat Higher-Order Aberrations (HOAs)as compared to PRK and LASIK which improves night vision.If a patient complains about residual refractive error post SMILE procedure which requires added vision correction, PRK is likely to be recommended for the best outcome.
Much like many new vision correction procedures, a surgeon is likely to perform significant number of follow-up procedures before honing their skills with the latest technology for minimal risk and optimum results. Always consult with the doctor as to which is the best refractive surgical procedure depending on nature of the anomaly and severity.
Most of the refractive eye surgeons would charge the same for both SMILE and custom LASIK for vision correction. The cost can range anywhere between $2,000 and $3,000 depending on the region and facility. It must be noted that prices tend to vary with contributing factors such as total fee of surgeon, experience, location of the procedure and possibility of follow-up examinations alongside additional treatments only if necessary.
If you’re near-sighted and meet the stated criterions, SMILE is the best laser vision correction procedure.
