Under what circumstances is it necessary to open the eyes

Canthoplasty is a plastic surgery for eyes that are too small or too far apart. It requires widening the palpebral fissure and shortening the distance between the eyes. Many female friends who want to have double eyelids need canthoplasty. Therefore, we must choose a regular hospital to perform canthoplasty. Now let us understand who are suitable for canthoplasty surgery. Everyone should choose the surgery according to their own situation.

Canthoplasty surgery is suitable for the following groups of people:

1. The surgery is suitable for those with small eyes: it can significantly widen the palpebral fissure, making the eyes slender and beautiful;

2. Eyes that are too wide apart: Removing the inner part of the eye can effectively shorten the distance between the eyes. Surgery can also effectively improve this situation;

3. Those who want to improve their double eyelids can have the surgery done at the same time to create attractive peach blossom eye shape;

4. Surgery can also help with drooping of the eye corners. If present, corrective surgery can be performed after 6-12 months.

5. Surgery can also help with drooping of the eye corners. If there is ptosis, ptosis correction surgery can be performed after 6 to 12 months.

Steps of canthoplasty surgery

1. Preoperative planning. Careful planning before canthoplasty surgery is the key to the success of the operation. First, communicate with the patient to understand the patient's requirements for the surgery, and then draw the line based on the doctor's experience.

2. Local anesthesia. After drawing the line, preoperative anesthesia is performed, and local anesthesia is used for canthoplasty. After anesthesia, the patient basically does not feel any pain during the operation. There is only slight pain during the incision and suturing, which is comparable to the pain caused by a needle and is acceptable to most people.

3. Cut and adjust. According to the preoperative design, the skin and conjunctiva of the outer canthus were fully cut with scissors along the horizontal direction of the outer canthus. Blunt separation is performed from the conjunctival incision upward and downward to the nasal side to release the fornix of the bulbar conjunctiva. Pull the bulbar conjunctiva horizontally to the apex of the incised lateral canthus, fix it with a stitch, and make interrupted sutures between the upper and lower fornix conjunctiva and the incised skin. If necessary, completely or partially cut off the lateral canthal ligament. At the newly formed lateral canthus, a mattress suture is made through the conjunctiva, the needle is brought out from the skin surface of the lateral canthus, and it is tied to the gauze pillow to form the (temporal) lateral dome. When suturing the conjunctiva and skin, if the tension of the conjunctiva is too great, the bulbar conjunctiva can be cut vertically between the outer side of the cornea and the outer canthus to reduce the tension. Ask the patient to open his eyes to see the correction effect of the epicanthus. Repeatedly compare the eyes to see if they are symmetrical and have the right shape, and make fine adjustments to achieve the most satisfactory effect. After the operation, apply antibiotic eye ointment in the conjunctival sac to prevent adhesion.

4. Suture. When suturing, use 5/0 silk thread to first sew a stitch at the junction of the middle and inner 1/3 of the upper eyelid, which is the widest part of the palpebral fissure. Insert the needle from the skin on the lower side of the incision, then pass through the anterior tarsal aponeurosis 1 mm below the upper edge of the tarsal plate, and then withdraw the needle from the skin edge on the upper side of the incision. Tie a slipknot with the suture and ask the patient to open his eyes to observe whether the width of the upper eyelid fold is appropriate and whether the skin on the lower side of the incision is bloated or too tense.

Experts say that for people with small eyes, canthoplasty surgery can achieve ideal correction and improvement effects. Canthoplasty surgery is divided into two directions: internal and external. Canthoplasty is used to correct microphthalmia. The inner and outer canthi must be enlarged. If necessary, medial canthal ligament fixation is required to correct the widening of the orbital distance, or ptosis correction surgery is also required. Congenital microphthalmia has narrow palpebral fissures, severe epicanthus, and is often combined with widened medial canthal distance and ptosis, so surgery needs to be performed in several sessions. Canthoplasty surgery is divided into two directions: internal and external. However, the specific method of operation is not entirely based on the patient's wishes, but is determined by a professional doctor based on the characteristics and conditions of his eyes.
