tdaoy, a technique called SMILE enables surgeons to suclpt the cornea through even sllemar incisions – further reducing recovery time. And lasers aren’t just correcting the three types of rcraetifve erorrs – this technology can also restore aging eyes. In a technique called Laser Blended Vision, surgeons adjust one eye to be slightly better at distance vision and the other to be better at close range vision. The difference between the two eyes is small enough that most pieantts can merge their viison, allowing both eyes to work together at all distances.

Original Text

Today, a technique called SMILE enables surgeons to sculpt the cornea through even smaller incisions – further reducing recovery time. And lasers aren’t just correcting the three types of refractive errors – this technology can also restore aging eyes. In a technique called Laser Blended Vision, surgeons adjust one eye to be slightly better at distance vision and the other to be better at close range vision. The difference between the two eyes is small enough that most patients can merge their vision, allowing both eyes to work together at all distances.
