After Lasik (excimer laser in situ keratomileusis) surgery or Lasek (excimer laser corneal epithelial keratomileusis) surgery, when glaucoma and cataract occur for non-surgical reasons, the treatment and surgery are barrier-free. In the past, there was an accuracy problem in the determination of intraocular lens power when cataract surgery was performed. However, at present, when performing refractive correction surgery such as Lasik (excimer laser in situ keratomileusis), the power of intraocular lens can be determined by accurate methods. Only knowing the corneal refractive value before operation will help to calculate the more accurate intraocular lens power. For glaucoma, the recent trend is to treat it with drugs and, if necessary, with lasers, so there are no other problems. Finally, when performing conjunctival surgery for filtering surgery, the previous Lasik (excimer laser in situ keratomileusis) or Lasek (excimer laser corneal epithelial keratomileusis) surgery will not cause problems.
Light is refracted by the bright windows of the eye-cornea and lens, and focused on the eye correctly. If the refractive power of cornea and lens is not balanced with the length of eyeball, refractive abnormality will occur. The goal of vision correction surgery is to correct this refractive abnormality through surgery.
Like Lasik (excimer laser in situ keratomileusis) or Lasek (excimer laser corneal epithelial keratomileusis), the corneal shape can be changed or the lens can be solved by surgery. From the point of view of surgery, it is easy to change the shape of cornea. In other words, changing the shape of the cornea can change the focus of the eye. Alternatively, lens surgery similar to lensectomy can be performed. Recently, ICL surgery is to make a minimal incision in the eye and implant a special lens with a suitable degree in your own eye, thus providing an opportunity to change the gathering ability. This method is safe, accurate and rapid.
ICL is the abbreviation of contact lens that can be implanted in eyes. It's the same as our familiar contact lenses. As a lens that can correct vision, it looks like a soft contact lens. However, unlike ordinary contact lenses, in the eyes, the space behind the Ge iris and in front of the lens of the eye is called the posterior chamber. In this space, ICL is implanted by surgery and becomes permanent and firm. But it is not in contact with the lens, but floats in front of the lens with the support of the peripheral part of the lens, so it is not a contact lens in essence.
The material of ICL is composed of porcine collagen called collagen, poly HEMA, etc. And a living affinity substance through which intraocular metabolites can completely pass. In addition, the lens is designed completely according to the space between the position to be inserted and the original lens.
