Concept of ametropia
Ametropia is a kind of ophthalmic problem that the eyes can not accurately focus the light to the retina under normal conditions, resulting in blurred vision. The common types of ametropia include myopia, hyperopia and astigmatism. As a professional eye hospital, Dalian Medical Ophthalmology Hospital provides patients with a variety of refractive error correction programs.
Scheme I of ametropia correction: glasses matching
Glasses matching is a traditional and common refractive correction method. According to the patient's diopter and personal needs, ophthalmologists will make appropriate glasses and lenses to correct vision by changing the refraction of light. As a non-invasive correction method, glasses matching has no irritation to the eyes and is suitable for patients of all ages.
However, glasses matching can not really change the refractive state of the eyes, and can only correct vision when wearing glasses, and has a certain impact on the appearance. For some people who have frequent activities and pursue a higher quality of life, they may not want to rely on glasses for a long time, and in some cases can not easily use glasses, so they may want to adopt other corrective schemes.
Refractive correction plan II: contact lenses
Contact lens is a kind of contact lens, which can attach the lens directly to the cornea. Compared with glasses, contact lenses have higher comfort and more natural appearance. The types of contact lenses include hard contact lenses and soft contact lenses, of which soft contact lenses are more common in the market.
Because the contact lens is directly close to the cornea, it can more accurately adjust the refraction of light, so the correction effect of vision is better. However, the requirements for the use of contact lenses are relatively strict, requiring patients to have some common sense of eye care, and to do a good job of cleaning and maintenance every day. When using contact lenses, check the health of the eyes regularly to avoid eye problems caused by improper use.
Scheme 3 of ametropia correction: corneal plastic lens
Ortho-K is a method of correction by wearing specially made corneal contact lenses. The patient wore a corneal shaping lens during sleep, and restored the cornea to its normal refractive state by shaping the cornea. After getting up in the morning, the patient can take off the lens, and the daytime vision will be effectively corrected.
Corneal plastic lens is a non operative and reversible correction method, which is suitable for some patients who are not suitable for laser surgery, such as children, teenagers and those who are worried about the risk of surgery. However, the use of corneal plastic lenses also requires patients to follow the guidance and requirements of doctors, and regularly check the health of the eyes to ensure the correction effect and eye safety.
Summary
In response to the demand for correction of ametropia, Dalian Medical Ophthalmology Hospital has provided a variety of solutions such as glasses matching, contact lenses and corneal shaping lenses. Glasses matching is a traditional and common way, which is suitable for patients of all ages. Contact lenses have high comfort and natural appearance, and can correct vision more accurately. Corneal plastic lens is a non operative correction method, which is suitable for some patients who are not suitable for surgery. Patients should make decisions according to their own needs and doctors' suggestions when choosing the correction scheme, and regularly check the eye health to ensure the correction effect and eye safety.
