What are the obvious techniques for myopia surgery in Zhongshan Ophthalmology Department?
With the increasing demands of modern people on the quality of life, myopia has become one of the common vision problems worldwide. In order to meet the demand, Zhongshan Ophthalmology Department, as one of the famous eye hospitals in China, has carried out a variety of myopia surgery techniques. Several techniques with obvious therapeutic effects are introduced below.
1. Laser keratoplasty (LASIK)
Laser keratoplasty (LASIK) is a widely used correction of myopia, which has obvious curative effect and mature technology. During surgery, doctors will use laser to grind a layer of tissue on the cornea directionally to change the curvature of the cornea. This kind of surgery can significantly improve myopia and let patients get rid of the trouble of relying on glasses or contact lenses.
LASIK is characterized by rapid recovery and less pain. Generally, patients can return to normal daily life within 24 hours after surgery. However, patients should communicate with doctors in detail before surgery to understand the risks and feasibility of surgery, so as to make a wise decision.
2. Surface grinding (PRK)
Surface grinding (PRK) is another common ophthalmic surgery, which is especially suitable for patients with thin corneas. This kind of surgery does not need to cut the cornea, but directly uses the laser to grind and reshape the eye surface.
The recovery process of PRK surgery is slower than that of LASIK surgery, because it takes a period of time for epithelial cells on the corneal surface to regenerate after surgery. The patient may have slight discomfort during the recovery period, such as dry eyes, blurred vision, etc. However, the long-term effect of PRK is comparable to that of LASIK, which can significantly improve myopia.
3. High order wavefront refraction surgery
High order wavefront refraction surgery is an advanced myopia correction surgery, which can adjust the optical system of the eye more accurately. This operation uses a laser correction mode that matches the individual eye features of the patient, and can effectively correct myopia, astigmatism and other visual problems.
Due to the high degree of individualization of high-order wavefront refraction surgery, detailed ophthalmic examination and evaluation are required before surgery. The procedure and recovery time of the operation itself are similar to those of LASIK and PRK, but the recovery effect after the operation is often more obvious due to the finer technology.
4. Intraocular lens implantation
Intraocular lens implantation is suitable for patients with moderate to high myopia. Intraocular lens can be used to change the refraction of the eye to correct myopia. This kind of surgery is usually carried out with the natural lens remaining outside the patient's eyes. After surgery, the patient can see distant and near objects clearly.
The postoperative recovery of intraocular lens implantation is fast. Generally, patients can gradually return to normal life within a few days. However, due to the complexity of surgery, patients need to conduct detailed assessment and plan formulation before surgery to ensure the safety and effectiveness of surgery.
summary
As a famous ophthalmic hospital, Zhongshan Ophthalmology Department has a variety of technologies for myopia treatment, such as laser keratoplasty (LASIK), surface grinding (PRK), high-order wavefront refraction surgery and intraocular lens implantation. These operations have the characteristics of obvious therapeutic effect, and can significantly improve the vision of patients. However, each operation has its indications and contraindications. Before selecting the operation, patients need to communicate and evaluate with doctors in detail to ensure the safety and effect of the operation.
