What is the effect of ICL phakic posterior chamber intraocular lens implantation technology?

ObjectiveTo observe the early complications and treatment of phakic posterior chamber intraocular lens (ICL) implantation** high myopia, and its causes. MethodsThe complications of 46 patients (92 eyes) who underwent ICL TIL implantation in our hospital during periiris resection and ICL implantation and six months after surgery were observed, and the treatment methods and conditions after treatment were recorded. ResultsThere was no pupillary block glaucoma in 1 case, and the intraocular pressure of 8 eyes increased after periidotomy before operation, and the intraocular pressure increased in 7 eyes after ICL implantation, all of which did not exceed 28 mmHg, and no special treatment was performed. The incidence of iris hemorrhage and pigment dissemination in the preoperative YAG laser periidotomy group was significantly higher than that in the surgical periidotomy group (2 eyes were damaged during surgery, and 1 eye underwent transparent lens extraction and intraocular lens implantation; After TIC rotated 2 eyes, the main manifestations of postoperative visual disturbance were shadow and glare in 1 case, and 1 case of postoperative visual psychological changes.

Conclusion ICL implantation** has few early complications of high myopia, which can be basically prevented and controlled, and the postoperative patient satisfaction is extremely high, and this surgical method is worthy of vigorous promotion.

ICL surgery, also known as phakic intraocular lens implantation, is a method of myopia correction that has developed in recent years. At present, depending on whether there is astigmatism, the cost of both eye surgery is about 35,000 yuan to 40,000 yuan. The specific cost depends on the consumption level of the region and the charging standards of different levels of hospitals, according to the specific situation of the patient, as well as the quality of ICL crystals, the material cost of ICL of different brands and functions is also different, you can go to the hospital for examination before the operation, and then you can comprehensively analyze an approximate cost according to your own situation.

There are certain risks associated with any surgery. ICL surgery is more effective than laser.

1. There may be glare, and you need to get used to it slowly.

2. There may be high intraocular pressure in the early stage, and regular examinations are required.

3. Other aspects depend on the level of the doctor and the equipment of the hospital, and the size of the crystal is basically nothing! In the long run, it's not clear. The technology is relatively new, and you don't know what will happen in more than a few decades!

4. The surgery is reversible, that is, it can be taken out if there is a problem, and it will not affect vision.

The effect is very good, so don't worry!

Lens implantation surgery should be done to correct myopia, especially in patients with high myopia or thin corneas. Because the cornea is relatively thin and the saturation is relatively high, laser surgery to correct the cornea may not be complete, so lens implantation is considered. Because lens implantation is an intraocular procedure, the risks are slightly greater than laser surgery, but not particularly high.

The main reasons are that cataracts may be slightly earlier than normal, or there is a risk of glaucoma, increased intraocular pressure, and then there may be rejection reactions, including a persistent decrease in corneal endothelial cells. At this time, the crystals may need to be taken out again, and then there will be no such symptoms. Therefore, it is not too serious a problem, as long as it is reviewed regularly and found in time, there will generally not be too many problems.

The best option for the treatment of high myopia is ICL lens implantation, which is an ICL intraocular lens that is a soft intraocular lens that will be placed in the safe area in front of the lens of the human eye. Clinical** for the correction of a wide range of myopia, farsightedness and astigmatism without the need to remove or destroy corneal tissue, without suturing after surgery.

ICL is a soft and healthy lens lens, which only takes 3-5 minutes to implant this ultra-thin lens into the human eye, and the implanted lens works with the eye to achieve the effect of correcting vision. It can correct myopia from 50 to 1800 degrees, astigmatism below 600 degrees, and has a wider correction range than lasers. Easy care after surgery.

Nowadays, ophthalmic cataract surgery is more common, cataract surgery may cause intraocular lens dislocation to lead to a second operation, but this probability is still relatively small, cataract surgery is generally a vision restoration surgery, but it depends on whether there is a lesion in your fundus. I hope to go to some good eye hospitals.

ICL lens implantation surgery is to implant a fine ultra-thin lens in the eye, the material has good biocompatibility, there is no adverse reaction in the eye, and it is suitable for ultra-high myopia above 1000 degrees. ICL lens implantation is an "addition" method, and the lens can be removed at any time if there is a problem, which means that this surgery has strong reversibility.

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 performed worldwide, and more than 99% of patients are satisfied with the results of the surgery 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.

I haven't had this surgery, but I'm a medical student and I've done it in an eye hospital. This is suitable for a relatively high degree of myopia, at least 600 degrees or more. The principle is to implant a new intraocular lens in your eye.

So in general, the effect is still reliable. But the level and responsibility of the doctor are important. Be sure to choose an experienced, responsible, and ethical doctor before you do it.

In fact, this is very similar to the form of cataract surgery.

ICL surgery is an abbreviation for anterior (posterior) intraocular lens implantation. To put it simply, ICL implantation is a pair of clear lenses that are placed in the eyeball, and are generally only used for patients with ultra-high myopia. Since it is an internal eye surgery, there is a greater risk and more postoperative complications during the procedure.

It was learned from the State Food and Drug Administration that ICL implantation was only approved by the relevant state departments in 2006, and the development of ICL in China is still immature.

ICL surgery requires surgery on the eyeball, with a total of 6 to 8 incisions in both eyes.

1. 2 4 yag laser periiris incisions (iris strophs can also be used for iristomy during the operation). Function: 1. Make the aqueous humor in the eye circulate around the lens to prevent the intraocular pressure from being too high. 2. In order to suction the posterior chamber viscoelastic agent after implantation of ICL.

2. Crystal adjustment incision 2 4. Function: Used to adjust the crystal.

3. 2 crystal incisions. Purpose: For lens implantation.

The consequences of infection in any infusion are very serious, because the incision leads directly to the inner eye, and the infection of the incision can easily spread to the inner eye, so antibiotics should be taken for at least a week after surgery.

Another point that needs to be reminded is that there is a lot of preoperative preparation for ICL surgery. In addition to the usual preoperative examination, a laser periidotomy is required in advance to prevent increased intraocular pressure after surgery. In addition, ICL is ordered according to the condition of each person's eyes, and it takes a certain amount of time to order, which generally takes 1 week to 3 weeks.

If you need to have ICL surgery, it will take half a month from preoperative examination to surgery, so be sure to arrange enough time.

Laser periidotomy and its limitations:

The method of this type of surgery is to photocoagulation and excision of the area with a laser (usually 532 laser), and then YAG penetration and flaring. However, bubbles are produced when 532 light is excited, and it is always difficult to see the distance from the cornea when focusing, so they dare not condense too much, which causes a small amount of bleeding in some patients when YAG penetrates. The edges of the yag are rougher when punching, and more energy and pulses must be used to fix them, so that there is more debris in the anterior chamber.

Are you very high? Did you go to the hospital for a check-up, and the doctor said that you can only do ICL?

If not, it is recommended that you do femtosecond lasers, which can be done with low power or high power.

The most important thing is that it is the safest and recovers quickly after doing it.

She did it in Preh.

If it is not a difficult situation, the ophthalmologists of the 2A hospital can do this kind of surgery very skillfully, and there are experts in this area in every province in China!

You don't necessarily need the best doctor in the country to perform the surgery, and many excellent eye hospitals have successfully performed this surgery.

It's better to choose LASIK, ICL is very risky. The sensational news about the Lasik surgery is that Prince William of England has gone to service in the British Air Force after passing the excimer ** myopia, an event known as the world's most expensive eye option.

My friend had LASIK surgery at one of the first excimer centers in Shenzhen to perform surgical correction of myopia, and it has been four years since everything in his eyes was normal, and there were no sequelae. The surgical equipment used in the excimer center is a new generation of individualized refractive workstation recommended by the National Optometry Engineering Research Center of China, which has advanced functions such as small spot scanning technology, three-dimensional automatic high-speed eye tracking technology, Q value, wavefront aberration and corneal topography map guidance technology, white light shadowless illumination technology, and even the surgical microscope is produced by the world-famous German Zeiss company. The advanced surgical equipment ensures faster surgery and clearer vision after surgery.

In order to ensure that the excimer laser equipment is in the most stable working state and outputs stable laser energy, the operating room of the optometry center maintains 24-hour constant temperature, constant pressure and constant humidity, and changes air 600 times per hour, so as to efficiently filter and disinfect the dust particles and bacteria in the air, and the air cleanliness can be achieved, which can reduce the probability of surgical infection due to surgical environmental factors to close to zero, and achieve an ideal environment for surgery. Although this type of operating room requires high maintenance costs, it is a real guarantee of surgical results.

Many people's first thought of surgery is to find a good doctor, but it is easy to ignore a more important condition, that is, surgical equipment. As common sense, we all know that the visual quality of a 1 million pixel camera and 8 million pixels cannot be the same, and the technology of Mercedes-Benz cars is also incomparable to ordinary micro cars, and surgical equipment, due to different brands and technologies, the purchase of ** is often different by millions, needless to say, the surgical effect made by the equipment that is so poor must be different.
