1, high myopia want to remove glasses, what are the surgical methods? Myopia of more than -6,00D (i.e. 600 degrees) is considered high myopia, and the main surgical methods to correct high myopia are corneal laser surgery (currently represented by full femtosecond smile, which mainly treats myopia below 1000 degrees) and refractive crystal surgery (currently represented by ICL, which mainly treats patients with more than 1000 degrees of myopia or whose corneas are not suitable for surgery). For older myopic patients who already have cataracts, we can consider doing crystal replacement surgery to treat cataracts and correct myopia at the same time. 2. What is femtosecond laser surgery? Femtosecond is 10-15 seconds, so imagine how short it is! Femtosecond laser is an infrared laser, which acts on the eye tissue with very low energy instantly in a very small space to form a very high energy density, and through photolytic blasting to produce tiny bubbles to separate the tissue, thus achieving corneal cutting. Compared to the traditional knife, it is not only more accurate, but also minimally invasive. Femtosecond laser surgery for myopia is commonly known as using a femtosecond laser to replace the cutting action of a knife to achieve minimally invasive, precise treatment of myopia. 3. Who can get better results with femtosecond laser? Can I get rid of my glasses completely? Any surgery has its indications, femtosecond laser surgery is no exception, the indications for femtosecond laser are: 18 years of age or older; myopia is relatively stable, myopia does not exceed -10D, astigmatism does not exceed -5D; the central thickness of the cornea is not less than 480um; the amount of corneal cutting and myopia is proportional, the deeper the myopia, the more corneal cutting, can be completely removed by femtosecond laser surgery. The more myopia you have, the more the cornea is cut, and whether you can get rid of your glasses through femtosecond laser surgery depends on the thickness of the cornea and the degree of myopia (patients with more than 1000 degrees may be better off doing crystal ICL surgery). 4.Who can’t have femtosecond laser surgery? Although femtosecond laser is minimally invasive and precise, not all myopic people can do it. Femtosecond laser surgery is not suitable for people with other eye diseases, such as tumors, autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, corneal abnormalities, such as cone cornea, corneal dystrophy, high myopia, thin corneal thickness, etc., which are not suitable for surgery on the cornea or have poor results (but the choice of crystal ICL surgery may be (but the choice of crystal ICL surgery may be good). So the surgery is personalized, not the most expensive choice, but the most appropriate choice. 5.What is ICL implantation surgery? ICL implantation surgery is, in layman’s terms, the equivalent of having a contact lens implanted in your eye. Of course, it is made of different materials than ordinary contact lenses. The full English name is implantable collamer lens, which is a special material, very soft and thin transparent lens, implanted through a tiny incision of less than 3mm, placed in the ciliary sulcus between the iris and its own lens, the operation time is short and vision is improved almost instantly, which is simply equivalent to moving frame glasses or contact lenses into the eye. Unlike the subtractive principle of keratomileusis, which requires laser cutting of part of the corneal tissue, ICL does not change the structure of the eye itself. Without cutting the cornea, it is a reversible procedure that can be removed and replaced at any time; and has high-definition visual quality. Minimally invasive, safe, reversible and high-definition are its characteristics. 6.Who can have ICL implantation surgery with better results? Can I completely remove my glasses? Theoretically speaking, as long as you meet the requirements of the surgery, you can have ICL surgery regardless of high or low myopia. Especially for patients with high or super high myopia, poor corneal shape or thin corneas, ICL has advantages that cannot be matched by other surgeries. Patients are generally between the ages of 18 and 55 and are in good general condition. Most patients with high myopia can get rid of their glasses through ICL implantation and get a clearer world than ever before, after a strict eye examination, excluding other eye diseases and autoimmune diseases. If the patient’s myopia exceeds -20D, ICL can also be combined with other surgical methods to correct the residual degree, such as ICL + full femtosecond smile surgery, ICL + LASEK surgery, etc., to completely get rid of the bottoms of the bottle! 7.Who can’t have ICL implantation surgery? Of course, each patient needs to undergo a thorough examination to determine if they are suitable. For those who are <18 years old, the refractive state of the eye has not yet reached stability, the myopia may further increase, and the eye structure is not yet fully developed, so it is not recommended for the time being (except for treatment of special cases). For those who are >55 years old, the patient may have already developed cataract, at this time, ICL myopia surgery will have a shorter duration of postoperative effect, and cataract surgery can be performed. In addition, ICL surgery is generally not recommended for women during pregnancy and breastfeeding. It should be emphasized that it is also not recommended for people with psychological abnormalities who have not been cleared for surgery by a psychologist or psychiatrist, such as patients who cannot understand the risks of surgery, are overly anxious or have unrealistic expectations. 8.Who is IOL replacement suitable for? What is the effect? Lens replacement is a cataract-like surgery, which is based on the principle of taking out one’s own lens and replacing it with an artificial lens. It is mainly suitable for people with high myopia or hyperopia who are older and have developed a cloudy lens (i.e. cataract). Since IOLs do not have the adjustment function of their own crystals (equivalent to a camera without zoom function), seeing far and seeing near cannot be satisfied at the same time, although there are also multifocal IOLs, but they are relatively lacking in visual quality. 9.Is it true that after high myopia is cured, the chances of retinal detachment and other fundus diseases will be less? All myopia surgeries only correct the patient’s myopia, but not change the nature of myopia and the condition of the fundus. Therefore, the fundus is unchanged after surgery for high myopia, and some of the possible fundus risks that exist in high myopia itself (such as the possibility of retinal detachment and other fundus diseases) remain unchanged and have nothing to do with ICL surgery, which neither decreases the risk of fundus diseases nor, of course, increases such risks.
