ICL intraocular lens replacement surgery is not to remove the own crystal

Hello, ICL implantation, also known as phakic posterior chamber intraocular lens implantation, is currently correcting myopia, especially high myopia.

The main way. The surgery does not require the destruction of corneal tissue, and the implanted lens can be removed if a problem is identified. At present, ICL implantation has become the preferred method for removing glasses in patients with high myopia. ICL is placed in the eye, and this lens contains water.

It is very tall and very soft, so it can be inserted into the eye through a very small incision. ICL is very lightweight, and the ICL lens is placed into the eye through a 3 mm incision, and the four corners of the lens are fixed to the suspensory ligament in the eye, allowing it to hang over the iris.

The back, in front of the lens, does not come into contact with its own crystals, and does not affect the position of its own crystals. In addition, there is a layer of fibronectin on the surface of ICL, which is used to inhibit inflammation and reduce the incidence of endophthalmitis; ICL itself is made of a special material, so it will not react with other tissues in the eye, adhesion and other problems, and will not cause rejection. The implanted lens is not visible from the outside after surgery, as if no surgery has been performed.

You are mistaken, ICL lens implantation and lens replacement are two types of surgery.

ICL lens implantation does not require removal of the own lens, and the appropriate age is 21 to 45 years old.

Lens replacement surgery is to remove the original lens, and then put an intraocular lens in, at the end of May, the national model worker driver in Xiamen ophthalmology high myopia department to do lens replacement, he is 53 years old, Dr. Zhang Chun suggested to do this, to remove his own lens, so that he will not have cataract problems in the future. Personally, I think that I should do ICL when I am young, and I will do lens replacement when I am older.

I did it here in April last year, and now I feel pretty good, my vision is still there, there are no adverse reactions, this surgery does not damage the cornea, and it is reversible.

Technically, ICL implantation is the implantation of an intraocular lens in the patient's phakic eye to maintain the natural accommodative function of the lens and adjust the refraction. Its advantages are high safety, good performance, and the operation is reversible, the surgical process is to implant an intraocular lens into the eye from a tiny incision, so as to achieve the purpose of correcting vision.

From the perspective of international and domestic authoritative certification, ICL surgery is another innovative scientific and technological achievement in the field of modern ophthalmic refractive treatment, and has also been certified by the US FDA, CE certification in Europe, and approved by the Food and Drug Administration of the People's Republic of China, and allowed to enter the Chinese medical device product market [registration number: Guoshi Food and Drug Administration (Jin) Zi 3221129 No.]. The raw material of ICL is the collagen polymer [Collamer] exclusively produced by the American company STAAR, which is polymerized from a small amount of purified collagen, which has good biocompatibility and no adverse reactions in the eye.

In terms of surgical cases, ICL implantable intraocular contact lenses have nearly 300,000 cases worldwide. ICL surgery has incomparable superior results in the correction of ultra-high myopia, and its high efficiency and safety have been practiced in many clinical practices at home and abroad, opening up a new field of refractive surgery.

Take it easy, there is a hospital that has also treated a 4800-degree myopia, and your 1200 is more promising. If you don't believe me, you can search for 4800 degree myopia surgery.

Have you already had ICL myopia surgery? The result? Because I'm planning to do this surgery too, but I'm a little worried about the outcome, I'd like to ask you.

ICL may have complications such as corneal endothelial damage and glaucoma.

1200 isn't very high.

Ordinary IOLs can be corrected.

Advantages of ICL lens implantation in the treatment of high myopia:

Myopia has a wide range of myopia, and can correct myopia up to 2500 degrees, hyperopia up to 1000 degrees, and astigmatism up to 600 degrees, and it only takes one surgery to complete.

It does not require high corneal thickness and is the only myopia surgery that does not harm the cornea.

Suitable for most people with refractive errors.

ICL lens implantation is well established and has a high safety profile.

Suitable for patients with ultra-high myopia.

Postoperative complications are low.

Lens implantation is an emerging surgical method that is excellent for solving the problem of high and ultra-high myopia! The operation is characterized by reversibility, high quality of viewing angle, and little change to the patient's eye structure! After surgery, there is a possibility of increased intraocular pressure, secondary glaucoma, and cataracts.

But as surgical techniques mature, complications become less and less.

1200 degrees can be considered ICL lens implantation, ICL is not possible for everyone, it is recommended to go for a preoperative examination first.

Indications for ICL surgery

The patient himself has the desire to improve his refractive status through ICL surgery, is mentally healthy, and has reasonable expectations for surgery.

Patients aged 21-45 years old with relatively stable myopia and astigmatism; The diopter was relatively stable (annual diopter change for 2 consecutive years. If there are special circumstances, such as those under the age of 21 or over 45 years old, they can be considered as appropriate if they have employment requirements, high anisometropia, corneal diseases, etc., and on the basis of full understanding, they must sign an informed consent form together with themselves or their family members.

The correction range is above myopia and astigmatism.

Anterior chamber depth , corneal endothelial count 2000 mm2, open angle. The cornea is morphologically stable and the lens is not progressively opacity. There are no proliferative lesions in the vitreous humor, and no active lesions in the macula and peripheral retina.

Special circumstances, such as those below the depth of the anterior chamber and relatively stable keratoconus, can be considered as appropriate.

No other ocular diseases and/or systemic organic lesions that affect surgical recovery.

Preoperative examination excludes contraindications to surgery.

ICL surgery has a history of 10 years in China and even longer in foreign countries, 20 years, and I personally think it is still very safe. There are two main reasons why it is safe, one point: he just puts an intraocular lens in his eye, and he does not cut the eye tissue.

Another point is that it is a reversible surgery, which means that you don't want to wear it in the future, and you can take it out.

Analysis:

After lens extraction combined with intraocular lens implantation, there will be dry eyes.

Guidance: Posterior capsular opacity may be associated with age as the problem of wearing glasses.

Lens implantation surgery is considered to be a refractive correction product that can compensate for LASIK, PRK, and other cutting procedures, and is one of the latest and safest products for the correction of high myopia, and is currently widely used in the United States. It can be used to correct a wide range of myopia, farsightedness, and astigmatism without removing or destroying corneal tissue and without the need for post-surgical sutures. ICL lens implantation has brought a boon to many patients with high myopia.

However, there are risks associated with any surgery, and when it comes to ICL lens implantation, patients with high myopia will inevitably think about the sequelae. According to the doctor, the most worrying thing about the sequelae after ICL lens implantation is the cataract problem, after all, the ICL intraocular lens is the same.

Being very close to the natural lens, the surgical procedure itself and interference with the natural lens may cause the clouding of the lens and lead to cataracts.

As long as the preoperative examination meets the conditions for surgery and the operation is carried out smoothly, the chance of sequelae is very small and almost impossible. And, even if this happens, high myopia surgery is reversible and can be remedied. Because, ICL crystals are planted.

The surgical principle of the procedure is that a soft intraocular lens is placed in a safe area near the lens of the human eye, without removing or destroying the corneal tissue. Therefore, if the patient is not satisfied with the postoperative results, the lens can be removed – something that is not possible with the LASIK procedure.

Postoperative Notes:

1. After a few days of ICL surgery, there is almost no obstacle to daily life, but it is forbidden to carry heavy objects or engage in strenuous exercise for 1-2 weeks. Also, do not rub your eyes too hard or put pressure on your eyes during the recovery period after surgery.

2. After surgery, you need to take medication according to the doctor's instructions and have regular rechecks.

3. Visual acuity varies according to the recovery of the wound at the pericorneal incision, but most of them heal and remain well. In addition, vision stabilizes after 1-2 weeks.

According to relevant data, ICL lens implantation myopia surgery has undergone more than 15 years of research and development to improve lens design, nearly 300,000 surgeries have been completed worldwide, and more than 99% of patients are satisfied with the surgical results in FDA clinical trials. The application record of ICL intraocular lens implantation has shown that the clinical results are stable and the results have been excellent.
