Technical Field
The utility model relates to a cornea shielding lens.
Background
The cornea is the foremost transparent portion of the eye, covering the iris, pupil and anterior chamber, and providing most of the refractive power to the eye. And the light can be accurately focused on the retina to form an image by adding the refractive power of the crystal. Common external ocular surgery for ophthalmology includes surgery of strabismus, eyelid, orbit, etc., and requires sufficient exposure of the operative field during the ocular surgery, which inevitably results in exposure of the cornea.
When in local anesthesia lower eye surgery, a patient can intuitively operate various surgical instruments used by doctors in front of eyes, psychological bearing force of the patient is tested in the whole surgery process, and the feeling is impressive and very unattractive for the patient. The operation light is directly irradiated, so that the patient has dazzling discomfort and the cooperation operation is affected.
In order to solve the above problems, chinese patent CN201310593512.9 discloses a disposable cornea protecting lens for ophthalmic surgery, which comprises a smooth lens surface and a lens inner surface, wherein the lens surface and the lens inner surface are integrally connected to form an arc-shaped lens body, and a cotton sheet for blocking light from entering the pupil is wrapped in an interlayer between the lens surface and the lens inner surface. The disposable cornea protecting lens for the ophthalmic surgery uses the cotton sheets in the lens to shade light, has strong shading capability, can reduce the stimulation of the surgical light source to the patient during the surgery, is safe and convenient to use, can be stably placed on the cornea of the patient, and makes the patient feel comfortable.
However, the disposable cornea protecting lens for the ophthalmic surgery is completely blocked by the cotton piece, and cannot meet the requirement when a doctor needs a patient to watch the light direction, so that inconvenience is brought to the doctor during the surgery; the surface of the lens is smooth, which is not favorable for being smoothly clamped and is inconvenient for putting the lens into and taking the lens off the eyeball. Therefore, it is desirable to design a corneal shutter glasses that ameliorates the aforementioned deficiencies.

Compared with the prior art, the cornea shielding mirror has the following beneficial effects:
(1) The middle part of the lens is provided with a frosted light-transmitting part, an annular cover is arranged around the frosted light-transmitting part, a layer of shading black film is tightly combined on the surface of the lens around the annular cover, the requirement can be met when a doctor needs to watch the lamplight direction of the patient, and the patient can watch the lamplight according to the requirement of the doctor through the frosted light-transmitting part, so that convenience is brought to the doctor operation; the annular cover is favorable for smoothly clamping the lens, and is convenient for placing the lens into and taking the lens off the eyeball; the shading black film can enable eyes of a patient to not see the operation position, so that fear can be reduced, light can be shielded in an auxiliary mode, eyes of the patient are prevented from being stimulated, and uncomfortable feeling is reduced.
(2) The surface of the annular cover also adopts a shading black film, so that the eyes of a patient can not see the operation position, fear can be reduced, light can be shielded in an auxiliary mode, the eyes of the patient are prevented from being stimulated, and uncomfortable feeling is reduced.
The utility model will become more apparent from the following description taken in conjunction with the accompanying drawings which illustrate embodiments of the utility model.
Drawings
FIG. 1 is a schematic view of one embodiment of a keratomask of the present utility model.
FIG. 2 is a schematic diagram of a second embodiment of the keratomask of the present utility model.
Fig. 3 is a schematic view of another embodiment of the keratomask of the present utility model.
Reference numerals illustrate: the lens 1, a lens surface 11, a lens inner surface 12, a frosted light transmission part 13, an annular cover 14 and a shading black film 15.
Description of the embodiments
Embodiments of the present utility model will now be described with reference to the drawings, wherein like reference numerals represent like elements throughout.
Referring to fig. 1-2, the corneal shutter lens includes a lens surface 11 and a lens inner surface 12, wherein the lens surface 11 and the lens inner surface 12 are integrally connected to form an arc-shaped lens 1.
The middle part of lens 1 is dull polish printing opacity portion 13, and when the doctor need the patient to look at light in order to make things convenient for the operation, the patient can see light through dull polish printing opacity portion 13, and dull polish printing opacity portion 13 can soft light simultaneously, makes light can not excessively stimulate patient's eyes, reduces uncomfortable sense.
