With the advancement of medical technology, myopia surgery methods have also been improved and developed, and there are many kinds of myopia surgery methods for patients and doctors to choose from. Is the more expensive the better? Or is it better to choose the one with the best price/performance ratio? The doctor can only recommend which procedure is suitable for the patient, but it is up to the patient to decide which procedure to take. So how should we choose the right surgery for ourselves? In general, myopia surgery includes two major types of surgery: one is excimer laser surgery, the principle of which is to correct myopia or hyperopia by cutting the cornea with an excimer laser to change the curvature of the cornea, and depending on the depth of the laser cutting cornea and the way the flap is made, there are two types of surgery: PRK, LASEK/EPI-LASIK, LASIK (ordinary LASIK, ultra-thin LASIK, SBK), and LASIK. LASIK, SBK) and femtosecond laser surgery. Each procedure can also be customized to meet the patient’s needs, such as adding Q-value guidance, topography guidance, and wavefront aberration guidance. The advantages are: simple surgical approach, high precision, fast postoperative vision recovery and good visual outcome. The disadvantages are: the surgery is done on the cornea, loss of corneal tissue, and dry eye can occur after surgery. The second type of surgical procedure is IOL implantation, which involves the implantation of an IOL in the posterior chamber to correct nearsightedness or farsightedness, including ICL, TICL and PRL surgery. The advantages are: no loss of tissue, the integrity of the cornea is maintained, the surgery is reversible, the lens can be removed after implantation, the scope of correction is wide, and the postoperative visual quality is good. The disadvantages are: the surgery is expensive, the preoperative and postoperative examinations are relatively complicated, and may lead to complications such as high eye pressure or cataracts. So how to choose a surgical procedure is a comprehensive criterion for evaluation. The surgeon will objectively recommend a surgical procedure for the patient based on the results of the patient’s examination. First of all, myopia is medically classified into low myopia (below 300 degrees), moderate myopia (300 – 600 degrees), high myopia (600 – 1000 degrees) and super high myopia (above 1000 degrees). For patients with normal corneas below 1000 degrees, doctors will give priority to excimer laser surgery, which is now very mature and is the most classic and commonly used procedure. However, the choice of the specific surgical procedure must be based on the patient’s refractive error and corneal thickness. Scholars at home and abroad generally believe that the remaining stromal thickness after corneal cutting must be above 250um to ensure postoperative safety, and most experts suggest that it is safer to try to be above 280um, that is, “preoperative corneal thickness – surgical cutting thickness – corneal flap thickness ≥ 280um”, and surgical procedures that meet the above conditions can be chosen with confidence. The above-mentioned conditions can be safely selected. Theoretically, the more the corneal thickness is saved, the safer the surgical procedure is. Since the corneal cutting thickness is certain, the only room for saving is in the thickness of the flap, which is common blade thickness > ultra-thin blade thickness, SBK thickness > femtosecond laser thickness, that is to say, femtosecond laser surgery has more advantages in making the flap and saving corneal thickness. For the relatively high degree of corneal relatively thin patients femtosecond laser surgery should be given priority, then the corneal thicker patients choose relatively more range, this time can be based on the patient’s own economic conditions comprehensive consideration, after all, the price of femtosecond laser surgery is still relatively expensive, choose blade flap relatively higher credit than price. The second is to tailor the surgical plan according to the examination results, patients with low astigmatism can use Q-value guidance, patients with high astigmatism use topography-guided surgery, patients with large pupils can choose wavefront aberration-guided surgery, these techniques can make the post-operative visual quality better. The surgical modality PRK, LASEK/EPI-LASIK, which does not require the creation of a corneal flap, is most suitable for low myopia below 300 degrees, but the significant postoperative pain and slow recovery of vision make this procedure a relatively poor choice. For ultra-high myopic patients with abnormal or too thin corneas, crystal implantation is undoubtedly the best choice. ICL and TICL implantation can correct myopia up to 2000 degrees and astigmatism up to 500 degrees, and PRL implantation can correct myopia up to 3000 degrees, and the high-definition visual quality after surgery has brought a great surprise to many ultra-high myopic patients, and crystal implantation is getting Some patients with low to moderate myopia and normal corneas are even willing to choose crystal implantation because after all, the surgery does not damage corneal tissue and the implanted crystal can be removed. However, the high cost of IOL implantation and the complicated preoperative and postoperative examinations and procedures still discourage most of the general myopic patients. In conclusion, the diversity of surgical methods brings more choices and convenience to patients and doctors. When choosing a surgical method, there is no need to blindly pursue the best surgery or the most expensive surgery, but you should choose the appropriate surgical method scientifically and rationally according to your own eye condition and economic conditions. By going to a regular hospital ophthalmology department and undergoing a thorough, standardized preoperative examination, there is always a refractive surgery that is most suitable for you, allowing you to remove your glasses and have a clear and bright world.
