Myopia, astigmatism, and slotxo congenital hyperopia are one other eye problems that make it difficult for everyday life. There are many options for solving eye problems today. Whether wearing glasses Implantable Collamer Lens (ICL) lens implantation, which is a correction of refractive state without damaging the corneal tissue. Does not dry out the eyes or cause inflammation. It also works well with natural intraocular lenses.
What is an ICL lens?
Dr. Thidanan Rattanatham, an ophthalmologist at Bangkok Hospital, said that the ICL or Implantable Collamer Lens is an implantable lens to correct abnormal vision problems. Whether it is myopia, astigmatism, using Collamer material that is gentle on the eyes. This lens can be folded into a small size, flexible, soft, moist and custom made from Switzerland according to eye preferences and individual problems. (tailor-made), where a skilled ophthalmologist will place an extra lens on the gap between the iris and the natural eye lens. To serve to correct abnormal vision conditions
The extra lenses will act like contact lenses. The only difference is that an extra lens is placed in the eye. Without changing the physical structure of the cornea Does not cause dry eyes. Does not thin the cornea. And can be removed (removable) to support future presbyopia lens technology or changes in vision. (With artificial lenses for cataract treatment)
The first solution to vision problems using ICL lenses began in 1993 in Russia. The first phase lenses solved the problem of myopia alone. And the lens has no drainage holes The laser has to be resurfaced later in order to puncture the drainage hole in the eye. Until now, ICL lenses were developed to correct nearsightedness, astigmatism, and congenital hyperopia, while presbyopia with age, ICL add-on lenses may provide partial near vision with two small holes. At the lens to drain water in the eye Reduces the effects of high pressure in the eye. That can be harmful to the eyes
People who are suitable for wearing ICL lenses
Have myopia (between 100 - 2,400) or astigmatism (between 25-600).
Have dry eyes Have a relatively thin cornea Or don't want location
Age 21 - 45 years because it is the age that eyesight is relatively stable.
There is a gap between the corneal lenses of more than 4-5 mm.
Not cataract Or other eye disease
Procedures for correcting vision problems with the use of ICL lenses
Starting from before undergoing surgery Patients will be given drops, dilators and anesthetics. The ophthalmologist will then make an opening of approximately 3 mm in the lateral edge of the cornea to insert an ICL lens through the space between the intraocular lenses. The pin of the accessory lens is located in the indent area under the iris. It takes approximately 30 minutes. The incision is small, about 3 mm. And can heal by itself without stitches. Less pain. Patients do not need anesthesia. The implant lenses that are placed on the patient are measured and tailored to correct problems according to each patient's vision. In order to be able to fit the lens that fits each eye so it is important to measure and order. After inserting the lens, the patient's vision will be clearer within hours of treatment. You can go home the same day without having to sleep at the hospital. Can be used in daily life normally And the lens can be removed Whether because of changing lenses Eyesight change in the future Or a state of cataract when aging
Advantages of ICL lenses
Made from a material called collamer (Collamer) contains collagen (Collagen) mixed with a copolymer (Copolymer), which has properties similar to the natural human cornea lens. Flexibility to match the natural lens. Because the vision of each person will be different. Eyesight level 20/20 will be the eyesight of people with normal eyesight. Which in people with myopia, astigmatism, presbyopia The implantation of an ICL lens corrects the eyes to a 20/20 level, ensuring high definition vision does not cause dry eyes or corneal inflammation. Help reduce the scattered light at night While helping to prevent UV rays and slow down the occurrence of cataracts Prevent damage to the retina Including helping to preserve eyesight for people who are limited if needing other forms of treatment.
The implantation of ICL lenses is another option for the treatment of myopia, astigmatism and farsightedness. Without thinning the cornea Including interchangeable lenses to correct eye problems It is important to be treated with an ophthalmologist with expertise and experience in refractive correction with lens implants. The availability of equipment and technology in the treatment is important.
