LASIK vs ZEISS SMILE: Which Procedure is Best for Me?

Featured Image

When you decide to pursue laser eye surgery to correct your vision, researching the procedures can be overwhelming. At Wang Vision Institute, we understand that every patient is different and deserves their own personalized treatment plan. Learn the difference between LASIK and ZEISS SMILE to help you understand which procedure is best for you.

What is LASIK?

LASIK stands for laser-assisted in situ keratomileusis and is the most popular refractive treatment in the ophthalmology field. LASIK surgery can be used to correct astigmatism, nearsightedness, farsightedness and more. While most ophthalmology centers continue to provide traditional LASIK procedures, Wang Vision Institute utilizes the latest tools and techniques to further maximize your laser vision correction surgery.

As an industry leader in laser eye procedures, Wang Vision is the first center in the state to use Soft-Touch LASIK. This surgery uses less pressure on the eye than traditional LASIK. Utilizing this technique provides a comfortable experience for our patients. Additionally, Soft-Touch LASIK is extremely quick, virtually pain-free, and known to provide lasting outcomes on your vision. 

What can I expect during LASIK surgery?

When patients undergo LASIK surgery at Wang Vision, they can expect the procedure to last a total of ten minutes from start to finish. Before surgery, the patient’s eyes will be numbed with eye drops to maximize comfort. Once the eyes are numb, a suction device will be placed over each eye to prevent blinking. Dr. Wang or Dr. Frenkel will then use the innovative laser to gently create a thin corneal flap and will use the laser to recontour the cornea. The flap is then placed into its proper position where it will self-heal with no stitches. Most patients can expect clear vision within one day.


ZEISS SMILE stands for small incision lenticule extraction and is a newly developed laser vision correction surgery that was first performed in Tennessee at our Nashville office! Similar to LASIK, ZEISS SMILE procedures use a precise laser to alter the shape of the cornea to improve vision. Along with other laser eye procedures, ZEISS SMILE works to reduce patients’ need for prescription eyeglasses and contact lenses by improving overall eyesight long-term.

How is ZEISS SMILE different from LASIK?

As a newer and more advanced laser eye procedure, ZEISS SMILE provides unique advantages compared to LASIK. ZEISS SMILE is less invasive because instead of creating a flap, it only requires a small incision. This leads to fewer complications post-operation. However, some people prefer LASIK over ZEISS SMILE because it is more commonly practiced by ophthalmologists. Additionally, ZEISS SMILE tends to have a slightly slower recovery time immediately following surgery.
