Treatment options for myopia include excimer laser treatment (including femtosecond), implantation of a lens eye IOL (implantable contact lens), and posterior scleral reinforcement. Posterior scleral reinforcement is a surgical treatment to prevent the progression of myopia, which requires laser treatment or implantation of a lens-bearing eye IOL in order to go without glasses. As you know, contact lenses are worn on the surface of the cornea (black eye) of the eye and are also called corneal contact lenses, while implantable contact lenses, also called lens eye IOLs, are glasses that are placed inside the eye. They are primarily used to correct myopia and/or astigmatism, and are particularly suitable for patients with high and ultra-high myopia and associated astigmatism where excimer laser cannot be done. The advantages of this implantable contact lens are: 1. Compared to excimer laser, a wider range of myopia can be corrected. For patients with thin corneas, dry eyes or large pupils that are not suitable for laser treatment, it is more appropriate to choose this lens-bearing eye IOL. 2, can correct both myopia and astigmatism 3, implantable contact lenses are similar to corneal contact lenses, the difference is that they are implanted into the eye, located behind the colored iris of our eyes, in front of the natural lens, the location is hidden, the surface is neither visible nor perceptible, and can achieve or even exceed the vision of wearing glasses 4, high accuracy, predictability, good post-operative visual quality, high patient satisfaction 5, this The lens is very light and soft, can be folded to a small size and implanted into the eye through a tiny incision, its material is close to that of the human lens and is easily accepted by the human body 6. The lens can be permanently implanted into the eye but can be removed when necessary, the lens does not cause any structural changes in the eye or cornea and is very safe How is the surgery performed? 1. First, a tiny incision of about 3mm is made in the part of the eye between the white and black color. 2. Then, a viscoelastic substance is injected into the eye through the tiny incision to protect the intraocular tissues. 3. Finally, the lens is injected into the eye, the position is carefully adjusted, and the viscoelastic substance is flushed out of the eye. Discomfort, to promptly inform the doctor for treatment, timely and correct treatment, will not lead to adverse consequences 2, a few hours after surgery can be left, postoperative can not force to rub the eye 3, according to the doctor’s requirements on time point eye, regular review, such as myopia continues to deepen year by year, you can consider removing or replacing
