What is refractive surgery?
The ametropia refers to that the light of the eye cannot be focused on the retina correctly after passing through the cornea and lens, resulting in blurred vision. This kind of refractive error can be corrected by glasses, contact lenses or refractive surgery, among which refractive surgery is a common treatment. As a high-level eye hospital, Chengdu Airui Eye Hospital provides a variety of refractive surgery to help patients recover their normal vision.
1. Traditional refractive surgery
Traditional refractive surgery includes LASIK (laser keratomileusis) and PRK (surface laser irradiation). These operations change the curvature of the cornea through laser technology, so as to achieve the purpose of correcting myopia, hyperopia and astigmatism.
LASIK is one of the most common refractive surgery. It creates a corneal flap, uses laser technology to change the shape of the cornea, and finally returns the flap to its original position. This process is usually fast and recovery time is short.
PRK is a kind of surgery that does not cut corneal flap, but directly uses laser technology to eliminate part of corneal tissue to change its curvature, thus correcting refractive error. The recovery time of PRK is longer, but it is suitable for some patients who are not suitable for LASIK.
With advanced laser equipment and a team of senior ophthalmologists, Chengdu Airui Eye Hospital can provide patients with safe and efficient traditional refractive surgery.
2. Intraocular lens implantation
In addition to the traditional laser surgery, Chengdu Airy Eye Hospital also provides intraocular lens implantation, which is an operation to correct refractive errors by replacing the lens. This operation is applicable to those patients who are not suitable for laser correction, such as elderly patients over 40 years old.
Intraocular lens implantation can correct myopia, hyperopia and astigmatism by implanting an intraocular multifocal lens. This intraocular lens can provide multiple focal lengths, so that patients can see clearly at different distances.
The expert team of Chengdu Airy Eye Hospital has rich experience. With advanced technology and equipment, it can implement safe and accurate intraocular lens implantation for patients.
3. Current trend of corrective surgery
With the continuous progress of science and technology, refractive surgery is also developing. At present, new technologies such as personalized laser surgery (such as excimer laser correction) and corneal ring implantation (such as corneal ring implantation) are gradually applied to the correction of refractive errors.
Personalized laser surgery through detailed eye examination in advance, according to the differences in the patient's own eye structure to develop personalized treatment program. This operation can more accurately correct the refractive error in the eyeball and reduce the risk of surgery.
Corneal ring implantation is to place a special stent ring in the center of the cornea to change its shape, so as to correct refractive errors. This operation is suitable for some special types of ametropia patients.
Chengdu Airui Eye Hospital has been constantly focusing on the development of new technologies, actively introducing and applying them to refractive surgery to meet the needs of different patients.
Summary
Refractive surgery is a widely used method to correct myopia, hyperopia and astigmatism. Through traditional laser surgery and intraocular lens implantation, Chengdu Airui Eye Hospital provides patients with safe and efficient options for correcting refractive errors. At the same time, the hospital also actively pays attention to the development of new technologies and introduces new technologies such as personalized laser surgery and corneal ring implantation to meet the needs of different patients. If you have ametropia, Chengdu Airui Eye Hospital will be your safe choice.
