? EVO-ICL is an intraocular lens that can be implanted in eyes, which can correct refractive problems such as myopia and astigmatism in different degrees. EVO-ICL implantation does not need to remove the tissue structure of the eye, and the operation is reversible.
? At present, for Evo -ICL implantation, the material used in the market is 2- hydroxyethyl methacrylate, which is a biocompatible polymer material based on porcine collagen and is very soft.
? Its collagen component can adsorb fibronectin in aqueous humor and form a layer of fibronectin around the lens, which can inhibit cells or foreign bodies in the anterior chamber from adhering to the lens surface and inhibit inflammatory reaction.
? Its fibronectin protective layer can prevent the crystal from being recognized as a foreign body, which can never be recognized in the eyes and keep it in a safe and static state.
Advantages of ICL intraocular lens implantation:
★ Because the lens is implanted in the posterior chamber of the eyeball and located behind the iris, it does not affect the appearance.
★ The crystal can be folded, so the operation is a small incision, and no suture is needed, which will not cause surgical astigmatism.
★ The correction range is wider, and the crystal is fixed by ciliary sulcus, which can correct astigmatism, with excellent visual quality and reversibility.
● Who can do ICL?
√ Age 18-55 years (the best age is 2 1-45 years).
√ Myopia is 50 degrees to 1800 degrees, and astigmatism is less than 600 degrees (height can be undercorrected or combined with corneal refractive surgery).
√ The diopter is relatively stable in recent two years (it is best to increase it by no more than 100 degrees within two years).
√ There is no serious organic disease and active inflammation in the eyes.
√ No serious illness, mental health.
● How should people with different degrees of myopia choose surgery?
① Corneal refractive surgery is generally chosen for mild myopia, with similar visual quality and reasonable price.
② Moderate and high myopia should be weighed between LASIK and ICL, and selected according to corneal thickness, astigmatism, pupil size, visual quality requirements and cost.
③ ICL implantation should be selected as far as possible for ultra-high myopia, and corneal laser surgery is not recommended for myopia above-12D.
● What are the precautions for preoperative examination?
① You need to stop using soft contact lenses 1 week, and stop using hard contact lenses for 3 months before coming to the hospital for examination.
② Examination items include optometry, ophthalmological examination and measurement of ocular biological parameters.
③ Basic surgical indicators: the depth of anterior chamber should be greater than 2.8mm, and the corneal endothelial cell count should be greater than 2,000 cells /mm? .
(4) After the examination, doctors need to make a comprehensive evaluation to judge whether it is suitable for operation and predict the postoperative effect.
Low intraoperative matters needing attention:
① Don't wear makeup on the day of operation, and try to wear loose clothes and comfortable shoes.
② The operation process is very fast, and it usually takes about 10- 15 minutes from preparation and cleaning to the end of the operation.
③ Try to relax during the operation, listen to the doctor's arrangement, keep your eyes open, and don't roll your eyes casually.
④ Put your hands on your sides or chest, and don't touch the facial disinfection area.
● Precautions after operation:
① Generally, you need to stay in hospital for several hours after operation, during which you should close your eyes and rest as much as possible, and measure the intraocular pressure in time.
② Tears, photophobia and foreign body sensation appeared within several hours after operation. Some friends may find that the white eyeball turns red locally after operation, which may be subconjunctival hemorrhage after operation, which is a normal reaction after operation.
③ On the second day after operation, vision basically recovered, and life and work were basically normal. But you need to take the medicine according to the doctor's advice.
④ Early postoperative eye rest should be paid attention to. In the early stage, the visual quality may not be very good in low light and dark light, so try to choose a room with good light to read books and watch computers. Do not watch computer, mobile phone, TV or play games continuously.
⑤ You can wash your face and take a bath immediately after operation, but avoid irritating liquid directly entering your eyes.
⑥ After operation, you can fly and participate in general sports activities. But please don't swim within 1 month after operation, and try not to participate in ball games such as basketball and football.
⑦ Follow the doctor's advice after operation. Usually 1 week, 1 month, 3 months and 6 months after operation, you need to come to the hospital for reexamination. It is also recommended to review once a year.
