Description

[0001] The present invention relates to an eye measurement system and an eye measurement system,

The present invention relates to an ocular measurement system and a method of driving the same, and more particularly, to a method of manufacturing and providing medical information and vision assistant means based on an eye condition, which can examine an eye condition of a subject's eye.

With the widespread use of smartphones and the environment in which computers are inevitably used, eye problems such as dry eye syndrome and decreased vision are emerging as side effects.

The eye condition can be divided into on-time, near-sight, primitive, and astigmatism. When a parallel ray emerging from an infinite object (usually more than 6 meters) enters the eye and focuses on the retina, it is called emmetropia, meaning that there is no refractive error. Myopia is the focus of the eye in front of the retina, and hyperopia when it is behind the eye. Astigmatism is called astigmatism when the refractive power of the eye is not the same across all meridians, that is, it is not perfectly spherical, and parallel rays can not focus at one point. These refractive errors, such as myopia, hyperopia, and astigmatism, are called ametropia.

In order to correct the irregular ocular condition, new treatment methods and devices are rapidly developing. Techniques and equipment that can be applied to the target patients who have not been adapted to the existing treatment method, continue to be developed.

Non-invasive treatment according to the ocular status can be performed by non-surgical procedures such as the use of vision assistant means such as eyeglasses and contact lenses, as well as by laser in situ keratomilieusis (LASIK) and laser-assisted subepithelial keratectomy (LASEK) You can divide it into an appropriate therapy.

However, although appropriate visual aids and surgical treatments have been developed depending on the state of the eye, in order to appropriately examine the state of the eye itself in advance, a medical institution or a company that manufactures or sells visual aids is required to visit the eye, There is a problem that the timely appropriateness of the examination is lost or it is difficult to take immediate action.

Specifically, the support portion 110 includes a fixing portion 111, and a plurality of the fixing portions 111 may be provided. The fixing part 111 may be provided on both sides of the supporting part 110. The fixing part 110 is disposed on the long side of the supporting part 110. The fixing part 110 extends from both sides of the supporting part 110 and is perpendicular to the supporting part 110. [ (B). One portion of the fixing portion 111 is drawn or drawn into the first receiving groove 112a formed on the side surface of the supporting portion 110 so that the first receiving groove 112a can move in the direction of the arrow in the drawing have.

The fixing portion 111 is inserted into the first receiving groove 112a to support both sides of the portable terminal 200 disposed on the back surface of the supporting portion 110, The terminals 200 may be fixed to each other. Accordingly, the ocular measuring apparatus 100 can be fastened to the portable terminal 200 corresponding to various sizes of the portable terminal 200.

Specifically, when the shape of the lens part 120 is circular, the lens insertion hole 113 may be a hole having an area corresponding to the area of the lens part 120, and may have a circular shape. However, the lens portion 120 is not limited to a circular shape, but may have various shapes such as a rectangle.

The lens unit 120 may be a concave lens. Accordingly, the lens unit 120 can display a placido ring (210), which is an eye condition detection pattern displayed on the portable terminal 200, in a curved shape and display it on the outside. The planar ring 210 corresponding to the spherical shape of the eye is emitted from the concave lens and irradiated to the eye to be examined 10 so that the degree of distortion of the shape of the plain ring 210 upon irradiation of the eye to be examined 10 Can be significantly reduced. The size of the place ring 210 displayed on the portable terminal 200 may be reduced according to the characteristics of the concave lens so that the place ring 210 may be irradiated on the eye to be examined 10, The plaque ring 210 can be appropriately irradiated to the cornea of the eye to be examined 10 by reducing the size of the plaque ring 210 so as to be suitable for an eye having a size smaller than that of the plaque ring 210. [

When the plasmid ring 210 is projected onto the cornea of the eyeball, eye conditions such as astigmatism can be detected through the degree of distortion of the concentric circularity ring 210.

The plasmid ring 210 is a concentric ring pattern developed by Placido, and assumes that the concentric ring pattern reflected from the human cornea is twisted based on the anterior shape of the cornea to be examined. And, if the curvature of the cornea changes extreme, such as a small radius or a bigger curvature, the ring may look more distant. For areas with a larger radius, the rings may look closer together. In the case of a perfectly spherical cornea, the ring remains concentric and uniformly spaced.
