Abstract
The utility model discloses a high-permeable-oxygen binding type invisible lens, which is characterized in that the invisible lens is provided with a plurality of holes. The utility model provides an invisible lens that makes a certain amount of holes on the ordinary binding type invisible lens and reaches the purpose of improving the oxygen-permeable performance of the invisible lens.
Description
Technical field
The utility model relates to a kind of ophthalmic medical articles for use, the bandage type contact lenses that particularly a kind of refraction correction surgery is used.
Background technology
Since last century, the eighties excimer laser was used for cornea ablation, excimer laser cornea refractive surgery had obtained developing rapidly in worldwide.China's myopia crowd quantity is huge, along with improving constantly of the The application of new technique and the people's lives general level of the health, refractive surgery is surging forward in recent years, and wherein the excimer laser cornea epithelial flap grinds edge art (Epi-LASIK) and Ethanol Method excimer laser cornea epithelial flap mill edge art (LASEK) has down become the most promising representative in the refractive surgery.All refractive surgery postoperatives all need be worn contact lens, are not shifted after keeping epithelial flap to reset, and the indwelling phase of contact lens is generally 3-7 days.The excimer laser cornea epithelial flap grinds edge art (Epi-LASIK) and Ethanol Method excimer laser cornea epithelial flap mill edge art (LASEK) down all needs a contact lens, be that the bandage type contact lenses come hold reset epithelium posterius lobe not to be shifted, the bandage type contact lenses except it physical dimension and the radian size most important be its oxygen permeability, the contact lenses of high oxygen flow are what keys of postoperative surgery recovery speed, visual quality height and postoperative complications.
Summary of the invention
At the problems referred to above, the utility model provides a kind of hole of stamping some on common bandage type contact lenses, reaches the purpose of the oxygen permeability that improves contact lenses.
In order to realize the foregoing invention purpose, the utility model provides high oxygen flow bandage type contact lenses, it is characterized in that, offers some holes on described contact lenses.
Reasonablely be that it is on some concentric circumferences in the center of circle that described hole is arranged on the described contact lenses with the center.
Reasonable is that described hole gauge is then arranged.
Reasonable is that described hole is a circular hole.
Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The synoptic diagram of high oxygen flow bandage type contact lenses structure is shown in accompanying drawing 1,2, and wherein Fig. 1 is a front view, and the thickness of the high oxygen flow bandage type of shown this contact lenses 1 is 0.1mm, and the glasses radius is 8.75mm.Fig. 2 is the vertical view of Fig. 1, does not punch at 10 places, the center of circle of these contact lenses 1, stamps hole (illustrated example is 20) regularly near circle centre position, during punching, is the center with the glasses center of circle 10, evenly punching on concentric circles, more than the hole beaten be circular hole.
Hole of the present utility model can be irregular, or the hole of other shape.
More than all embodiment only for the explanation the utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
