If you are nearsighted, is it better to have laser surgery or lens value surgery?

ICL implantation, also known as phakic intraocular lens implantation, is currently considered to be a new technology that can replace LASIK, PRK and other cutting surgeries for refractive correction, and is currently one of the latest and safest surgeries for myopia correction in the world.

ICL surgery is an advanced technique in which an intraocular lens is implanted into the eye, which is equivalent to placing a pair of tiny glasses inside the eyeball.

ICL lens implantation, also known as phakic posterior chamber intraocular lens implantation, is to place this "implantable ultra-thin contact lens for correcting refractive error" in the posterior chamber space of the eyeball refractive system and fix it in the ciliary sulcus to achieve the purpose of long-term correction of refractive error. In addition, ICL lens implantation has several advantages:

Wide range of correction: It can be used to correct a wide range of myopia, farsightedness and astigmatism, especially medium and high myopia.

No corneal damage: The operation does not require cutting the cornea, and the healthy corneal tissue can be completely preserved.

High safety: The surgical incision is small, no sutures are required, and the structure and shape of the eyeball tissue will not be changed.

Fast time: The surgical process only takes 15 minutes, and the results can be seen on the same day, without affecting normal work and life.

Strong reversibility: If the patient is not comfortable with the implanted ICL lens, it can be replaced or removed at any time and the glasses can be re-fitted.

Good stability: After ICL lens implantation, there is no foreign body sensation in the eye, and the implant will not bind to any tissue.

Design science: ICL crystals are fixed in the ciliary sulcus with a double-sided arch design, and do not touch their own crystals.

Convenient post-operative care: ICL lenses are designed for long-term implantation inside the eye without the need for professional care.

However, whether everyone is suitable for this kind of surgery is known only through strict preoperative examination, and only through strict preoperative examination can we determine the appropriate surgical method for each person.

Surgical Requirements for Myopia Surgery:

1. Must be over 18 years old.

Myopia under the age of 18 is still in the stage of vision development. Myopia can be treated with medication**. It is generally recommended to take two packs of Joy Vision Nutrients a day, and insist on taking it for a period of time, the degree of myopia will be reduced, the vision will be improved, and there is no need for adult surgery.

2. The degree of myopia is between 100-1500 degrees, the degree of astigmatism is within 400 degrees, and the vision is stable for more than two years.

3. There are no other ophthalmic diseases, which do not affect the postoperative recovery.

4. The thickness of the cornea is thick enough.

After preoperative examination, only those who meet the requirements of surgery can be operated.

Laser surgery is suitable for low-grade myopia, and lens implantation is suitable for high-grade myopia, which can be selected according to the doctor's advice and your own situation.

Both lens implantation and laser are good. For each type of myopia eye surgery, it has a certain range of adaptation, such as phakic intraocular lens implantation, which is more suitable for those with high myopia and thin corneal thickness. Laser myopia eye surgery is suitable for those with a relatively low degree of myopia, but the corneal thickness itself is better.

The laser correction method is operated on the surface of the patient's cornea, and does not enter the eye, and the lens implantation surgery requires a customized lens to be installed in the eye, so it is not possible to say which surgical method is better, but usually if the surgery can be performed on the outside of the eye, there is no need to perform the operation inside the eye.

1. When performing surgery in the eye, the risk of complications is relatively large; 2. There are many benefits of lens implantation surgery, if the patient's cornea is too thin or the myopia is too high to undergo laser surgery, lens implantation surgery can be selected; 3. If there is a risk in the operation, the patient can remove the lens before the risk is more serious.

Lens implantation is an option for patients with ultra-high myopia and some patients who are not eligible for laser surgery.

Lens implantation surgery and laser surgery have their own advantages and disadvantages, and the most suitable surgical method for the patient is the best. Lens implantation does not require ablation of the cornea and is more suitable for patients with myopia above 1200 degrees; Laser surgery is commonly used in excimer laser surgery, which is suitable for patients with high myopia and ultra-high myopia and thin corneas, and laser optical keratomyctomy, which is suitable for patients with myopia below 700 degrees. In addition, after surgery, it is necessary to pay attention to eye care, maintain eye hygiene, use eyes reasonably, eat more fruits and vegetables, and maintain adequate sleep, which are conducive to reducing postoperative adverse factors.

For **myopia, whether to use an intraocular lens or a laser is mainly decided according to the condition and power of the eye and the indication of surgery, and there is no better one. Intraocular lens implantation is mainly to implant an artificial intraocular lens, in front of the original lens, to achieve the purpose of correcting vision. Generally, a small incision is made in the cornea and the lens is implanted, which does not cause major damage to the eyeball, and is suitable for patients with myopia with a relatively high degree.

Corneal laser resection surgery changes the shape of the cornea to achieve the purpose of correcting vision, and the cornea is not the original shape after the operation, and the intraocular lens implantation does not change the eye in any way.

The two types of myopia eye surgery are relatively mature at present, as long as they are selected according to the individual's situation. Laser surgery is an external eye surgery, and intraocular lens implantation surgery is an internal eye surgery, which requires higher technical requirements for internal eye surgery, and the requirements are also higher.
