I want to take advantage of the holidays to have an excimer surgery, is there anything I should pay

The potential problems after excimer surgery are mainly as follows: (Potential problems are: most people do not have these problems after surgery, but the following problems occur in laser surgery, so this part of the risk should also be considered).

1.Incomplete corneal healing leads to the risk of the previously mentioned incision "cap" falling off and deforming

It occurs in the perioperative period (Melki & Azar, 2001), and "it is unknown how many years after surgery the risk of shedding decreases, and to the best of our knowledge, the longest case of corneal flap fold due to external trauma is 7 years after surgery" (Ursea & Feng, 2010).

2.Patients are at risk of corneal deformity after surgery, keratoconus (ectasia).

23 4027 eyes, i.e., 7 years after surgery (Spadea, et al.)., 2012)

3.Not 100% sure of postoperative visual acuity accuracy:

These include vertigo, ghosting, and visual fluctuations caused by the corneal "central island" (Melki & Azar, 2001).

4.The eye is at risk of trauma from external pressure (this refers to the "punched" hit that many people ask about, rather than rubbing the eye).

The real case comes from Ursea & Feng, (2010), in this report, a patient who was 6 years after LASIK was punched and the corneal flap was detached, but fortunately the doctor helped him to redo the operation in time, and his vision was saved perfectly.

5.Risk of infection and inflammation during postoperative healing.

6.During surgical healing, epidermal cells proliferate into the middle of the surgical wound in the corneal stroma, causing visual risk that affects vision.

Directly after the first surgery, it occurs when the corneal flap is lifted again for a second operation.

7.Dry eye syndrome (a common postoperative problem, not pathological, usually solved by artificial tears, but in severe cases, it can affect normal life) (6 months after surgery) The difference in the proportion comes from the direction of the incision of the corneal flap

There are many intimate friends who have privately messaged that they have had laser surgery, what should I do if my eyes are dry?

Personally, I think you can try artificial tears and wear blue-light blocking glasses.

The anti-blue light glasses have the function of 97% blue light filtering, which is not expensive. If you use a lot of computers and mobile phones after surgery, you can use it.

The most serious of these, point 6, can be blinding, and the only solution in the later stages of development is corneal transplantation.

To my surprise, many people who opt for laser surgery don't know what to know:

The corneal flap that is cut in steps 2 and 3 cannot be completely healed after the last step is closed, only the epidermal cells of the cornea are healed, and the large area of corneal stroma in the middle is just attached together.

Excimer surgery is not suitable for everyone, and rigorous preoperative examination can effectively avoid the occurrence of such conditions and give patients the safest **. It includes a number of preoperative examinations such as refractive examination, corneal thickness examination, corneal curvature examination, etc., which can perfectly detect excimer contraindications such as keratoconus, and add a safety valve for the safety of surgery.

1. Eat a reasonable diet.

2. Eye cleaning: Patients must wash their eyes according to the method taught by the doctor to avoid eye infection.

3. Protect your eyes: try to avoid being hit hard by external forces.

4. Eye hygiene: Patients need to follow the doctor's instructions to use the correct way of using eyes, such as the time and method of reading, TV, computer, driving a car, etc.

5. Postoperative medication: patients must follow strict medical instructions, under normal circumstances, the doctor will inform patients of postoperative routine medication, and patients must not change and stop medication by themselves. In addition, the patient must follow up regularly according to the doctor's request, and the doctor will adjust the medication regimen according to the patient's eye condition.
