The technology of surgical treatment of myopia is rapidly improving. Many years ago myopia surgery may have had one problem or another, but the current technology of myopia surgery is not what it used to be, with no complications and a quick recovery. LASIK (Laser Excimer In Situ Keratomileusis) and LASEK (Laser Excimer Epithelial Keratomileusis) can avoid and reduce some of the complications, and the recovery is fast and without significant discomfort, so they are widely used, especially the former, which is the most widely performed and most widely used. The former, in particular, is the most performed and widely used surgical method. The invention of this advanced technology makes the sequelae of myopia surgery almost zero. What are the sequelae of lasik surgery – what are the key factors affecting the outcome of the surgery? The outcome of the surgery is directly related to the experience of the surgeon, the performance of the equipment, the environment of the operating room, the service of the surgeon and the patient himself. The experience of the surgeon is decisive for the safety of the procedure. Operating a corneal lamellar microdissection is complex and therefore requires a skilled ophthalmologist. Experienced surgeons are also able to handle the complexities of individual differences during the procedure to ensure the safety of each patient, which is difficult for inexperienced surgeons to do. The majority of patients have very good results and have removed their glasses, and are very stable, individual patients with one or two thousand degrees of myopia can only reduce the number of degrees of treatment, and then wear low-degree myopic lenses or depending on their naked eye vision, also The patient may not wear glasses. The patient generally wears glasses before surgery degree stable, the postoperative effect will also be stable, in addition, after surgery to pay attention to eye hygiene, not fatigue eye, on time point eye medicine, is also an important factor in the postoperative effect of stability. What are the sequelae of lasik surgery – the principle of surgery Excimer laser in situ keratomileusis (LASIK) is to use the beam of excimer laser precisely controlled by computer to change the curvature of the anterior surface of the cornea in order to correct the refractive error of the eye, so to speak, is to grind out a pair of suitable eye ytterbium on your own cornea, so that External light can be accurately converged and imaged for the purpose of correcting myopia.
