Eye opening surgery is one of the most popular surgeries in Asia. It is the dream of countless beauty seekers to make their eyes look bigger and more attractive by surgically opening up the inner and outer corners of the eyes. Is it really as good as it is advertised? What are the risks of this surgery? This article will answer the above questions one by one. First of all, the inner corner of the eye, before the inner corner of the eye surgery explained need to understand a concept – the inner canthus, the inner canthus is a characteristic structure of East Asians, refers to the skin tissue that covers the front of the tear mound. Because of this structure, the inner corner of the eye is not as open as in Caucasians, and the horizontal diameter of the eye is shorter. To remove the canthus, a surgical procedure called canthoplasty is required. This is called canthoplasty. The canthoplasty will make the eyes larger in cross-section and, when combined with blepharoplasty, will give the eyes a better appearance. However, it should be noted that the biggest problem with canthoplasty is the scar formation at the inner corner of the eye. Unlike blepharoplasty, the scar at the inner corner of the eye is not covered by the skin but is directly exposed. Therefore, doctors suggest that the inner canthus opening is suitable for the more serious moderate canthus or above. For mild canthus, doctors do not recommend it because the improvement effect of the eye angle is rather less than the effect caused by the scar. The following talk about the outer corner of the eye, it should be solemnly pointed out here that the scar of the outer corner of the eye surgery is more obvious than the inner corner of the eye, so this surgery is only suitable for pathological eye deformities such as microphthalmia, etc. In the cosmetic category must be very cautious, our hospital has seen a large number of patients who underwent outer corner opening and needed scar revision. In summary, eye surgery is not the magic of imagination, perfect, you must think twice before surgery.
