Bijumax800 Smile Pro-Night Correction Accuracy, Better Than Smile LASIK
Nov 17, 2025
It is a time when the number of eye correction surgeries for test takers who have completed the CSAT increases.
This is to take off the uncomfortable glasses that have been used since elementary, middle and high school days ahead of college entrance. In recent years, test takers' vision correction surgery has a high preference for Smile LASIK and SmilePro, which use advanced equipment called VisuMax, beating the past methods of LASIK and LASEK.
However, if near-sightedness is accompanied by near-sightedness that is hard to see in the distance and astigmatism that overlaps and spreads objects or letters, care should be taken in choosing surgical methods. Astigmatism is a refractive disorder in which light transmitted through the cornea cannot be concentrated at a point in the retina and two or more points of focus occur. Two to three diopters are classified as moderate, and four diopters or higher are classified as advanced astigmatism, and advanced astigmatism should be carefully approached for safety. Seventy to 80% of myopia patients in Korea are accompanied by astigmatism.
Kim Boo-ki's team at Onnuri Smile Eye Hospital in Gangnam recently announced the results of a clinical study that SmilePro's astigmatism correction accuracy is significantly better than Smile Lasik at the European Cataract Refractive Surgery Society (ESCRS) held in Denmark.
In vision correction, astigmatism requires much more precise axial alignment than simple myopia correction. Even if the axis is twisted by only 10 degrees, the correction effect can be reduced by 30%, and in particular, high astigmatism correction is known to be a field with very high surgical difficulty. SmileLasic (Bizumax 500) and SmilePro (Bizumax 800), which have recently become the most popular laser vision correction surgery, can be corrected with moderate astigmatism below 5 diopter.
The medical staff objectively compared and evaluated the calibration accuracy of Smile LASIK and Smile Pro in the same surgical environment for astigmatism patients between 3 and 5 diopters. As a result of follow-up for 3 months after surgery, the overall vision improvement effect and safety were good and similar in both surgeries.
However, astigmatism correction accuracy improved more clearly in the group receiving SmilePro. The proportion of eyes below 0.5 diopter of residual astigmatism was 54% in SmileLasic, compared to 66% in SmileLasic. In addition, the proportion of eyes with less than 1 diopter of residual astigmatism was 93% in the Smile Lasik group, and the Smile Pro group showed a higher proportion of 98%.
The calibration index was 0.90 (10% undercalibration) on SmileLASIK, while it improved to 0.96 on SmilePro, reducing astigmatism undercalibration by less than half.
Medical staff explained that this result is because the Smile Pro, which uses the Bijumax 800, has made technological innovations that increase laser speed and surgical accuracy. SmilePro is a next-generation laser system that can provide more precise vision correction effects not only for highly astigmatism patients but also for general myopia patients. In particular, it is equipped with a center alignment and correction system, which automatically corrects fine rotation or positional deviation of the eyes during surgery.
Director Kim Boo-ki of Gangnam Onnuri Smile Milean said "This study demonstrated that SmilePro can overcome the limitations of astigmatism correction, especially for test takers with astigmatism along with myopia." he said.
Of course, test takers with advanced astigmatism of more than 5 diopters should approach the surgery more carefully. Smile cannot be operated on itself for safety reasons, and it is difficult to solve even with conventional LASIK or LASEK. In this case, the safest and most effective method is to choose lens insertion surgery (ICL) or to reduce astigmatism with astigmatism correction surgery first and then to resolve myopia with smile LASIK or smile pro.
Chung Young-taek, director of Onnuri Eye Hospital in Jeonju, explained, `It is important to minimize corneal damage and restore the desired vision by focusing on safety above all else in correcting the examinee's vision,' adding, `It determines the quality of vision and eye health to accurately examine astigmatism along with myopia and choose the appropriate vision correction method.'
