Difference between OK mirror and traditional correction method

The development of ophthalmic technology makes the methods of eye vision correction more and more abundant and diversified. The Ophthalmology Department of the Third Hospital of Zhongshan, Guangzhou, provides two options: OK mirror and traditional correction method. These two methods will be described in detail from four aspects, so that readers can better understand them.

First aspect: correction principle

OK lens is a special corneal contact lens, which can correct myopia, astigmatism and other refractive errors by changing the shape of the cornea. It is made of highly breathable materials, which can provide enough oxygen for the cornea. The traditional correction method is to wear glasses or corneal shaping lenses to make the light reach the correct refractive state before entering the eyeball.

The main difference between the two methods lies in the different correction principles. The OK lens is corrected by changing the shape of the cornea, while the traditional correction method is to use lenses outside the eyeball.

Second aspect: usage

The use method of OK lens is relatively complex, which requires accurate measurement of corneal curvature, and customized lenses according to the measurement results. Patients need to wear glasses every night before going to bed, and keep them for several hours to achieve corrective effect. The traditional correction method is very simple, just need to wear matching glasses or corneal shaping lenses.

In addition, OK lenses need to be revisited regularly to ensure the stability of the correction effect, while traditional correction methods can adapt to the changes in vision by changing lenses or matching glasses regularly.

Third aspect: applicable population

OK lens is suitable for people with myopia, astigmatism and other refractive errors, especially those who are not suitable for surgery. It can be used in the eye development of children and adolescents, and is very effective to avoid further deterioration of vision. The traditional correction method is applicable to all ages, and it is also a good choice for people who are not suitable for using OK mirror.

Fourth aspect: effects and side effects

The correction effect of OK lens is usually very good. The vision can be significantly improved after wearing it for a period of time. At the same time, it has no negative impact on the health of the eyes. The correction effect of the traditional correction method is similar to that of the OK lens, but the opaque glasses will affect the normal appearance and limit the vision.

The side effects of OK mirror mainly include discomfort and eye pain, which usually disappear after a period of use. The side effects of traditional correction methods are mainly the opacity of glasses and limited vision, which have no negative impact on the eyes themselves.

To sum up, there are some differences between OK mirror and traditional correction methods in terms of correction principle, use method, applicable population, effects and side effects. The selection of appropriate corrective methods needs to be determined according to the needs of individuals and the recommendations of ophthalmologists.
