LASIK (laser-assisted in situ keratomileusis) is one of the best known types of refractive surgery today. LASIK can improve vision problems caused by farsightedness, farsightedness, astigmatism, to presbyopia. Along with the development of technology, a more recent version of conventional LASIK was developed, namely LASIK Xtra.
What's the difference between LASIK and LASIK Xtra?
The LASIK procedure usually uses a laser beam to reshape the surface of the cornea, so that incoming light from outside can fall right on the retina. This is done by the doctor by making a small incision in the cornea, called a flap. Then, some of the tissue inside will be removed by laser shots. The final action is to close the flap back as usual.
The LASIK Xtra action is not much different from conventional LASIK, it still begins with making a flap with an incision. The difference is, the doctor will drop riboflavin 0.1% at the end of the LASIK Xtra procedure before the flap is closed. Then, the doctor will light the eyes with UV light after the flap is closed.
Benefits of LASIK Xtra compared to conventional LASIK
LASIK Xtra is estimated to have a lower risk of side effects than normal LASIK.
1. Helps overcome the weak corneal structure
The normal LASIK procedure that requires making flaps while removing part of the corneal tissue causes the cornea to weaken. In some cases, this corneal weakness causes your sharp vision to decrease dramatically.
The existence of LASIK Xtra helps strengthen the weak cornea due to LASIK actions without changing the patient's visual acuity.
2. Keep vision focused
In some cases of LASIK for plus or minus eyes with a degree that is too high, the sharpness of vision afterwards can not be too focused. Well, LASIK Xtra does not bring side effects like this. The LASIK Xtra action can actually maintain a better focus on the eyes.
Moreover, as long as it is carried out by experienced ophthalmologists, this procedure does not have significant side effects.
Who needs LASIK Xtra?
Until now, LASIK Xtra is still not recognized in the United States, but has been used in more than 50 countries in the world. This action is generally carried out in patients with conditions, such as:
- Nearsightedness (eyes plus)
- Minus high eye (> 6 diopters)
- Young age (<30 years old)
- Astigmatism (cylindrical)> 1 diopters
- The difference in astigmatism between the two eyes> 0.5 diopters
- Thin corneal structure
