Abstract
The invention discloses a bandage type soft corneal contact lens which is characterized in that the corneal contact lens is a soft corneal contact lens which is provided with a basic arc and comprises multiple strengthening circles, wherein the base has the thickness of 0.03mm; the number of the strengthening circles is four; three inner-ring strengthening circles have the width of 0.25mm; and the outermost ring strengthening circle has the width of 0.5mm and the thickness of 0.07-0.08mm and is integrated with the base. According to a method for reducing the thickness of the contact lens, the oxygen permeability of the soft corneal contact lens is improved, and the thickness of the contact lens is reduced by increasing the strengthening circles so as to reduce the strength, so that the speed of corneal recovery of a patient is increased, the visual quality is improved, and postoperative complications are reduced.
Description
Technical field
The present invention relates to a kind of ophthalmology dioptric articles for use, the bandage type soft corneal contact lens that particularly a kind of refraction correction surgery is used.
Background technology
From the eighties in last century, excimer laser is for since cornea ablation, and excimer laser cornea refractive surgery is developed rapidly in worldwide.China's myopia crowd quantity is huge, along with the application of new technology and improving constantly of the people's lives general level of the health, Ethanol Method Laser subepithelial keratomileusis (LASEK) wherein, microkeratome method excimer laser subepithelial keratomileusis (Epi-Lasik), femtosecond laser original position keratomileusis (FS-LASIK) technology has become the most promising representative in refractive surgery.After this class refractive surgery, patient all needs wearing of contact lens, and to keep postoperative epithelial flap, corneal flaps not to be shifted, the indwelling phase of contact lens is generally 1-7 days.This just needs the soft corneal contact lens of high oxygen flow.In recent years, the soft corneal contact lens that also needs high oxygen flow for the built-in small-bore of cornea of the elderly's solution " presbyopia " problem.So being cornea related surgical, the soft corneal contact lens of high oxygen flow recovers speed, postoperative visual quality height and the how many key of postoperative complications.
The soft corneal contact lens of high oxygen flow, except the high oxygen permeability of material, the thickness of eyeglass is also crucial, accomplishes thinly moulding to wear again, the invention technical requirement of Here it is bandage type contact soft lens.
Summary of the invention
The object of the invention is to provide a kind of bandage type soft corneal contact lens of high oxygen flow.
The present invention for achieving the above object, adopts following technical scheme:
A bandage type soft corneal contact lens, is characterized in that: described contact lens is four soft corneal contact lenses of strengthening circle that have of tape base arc, and substrate thickness is 0.03mm.
It is further characterized in that: it is 0.25mm that described three inner rings are strengthened circle width, and it is 0.5mm that outmost turns is strengthened circle width, and thickness is that 0.07-0.08mm and substrate become one.
Preferred: described reinforcement circle is four concentric round belts, its diameter is respectively φ 5/ φ 5.5, φ 8/ φ 8.5, φ 11/ φ 11.5, φ 14/ φ 15.
The present invention improves the oxygen permeability of soft corneal contact lens by the method for attenuate contact lense thickness, by strengthening circle, increase the intensity reducing because of attenuate contact lense thickness.Thereby accelerate the speed that patient's cornea recovers, improve visual quality, reduce the generation of postoperative complications.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is vertical view of the present invention.
Embodiment
A bandage type soft corneal contact lens as shown in Figure 1, 2, substrate thickness is 0.03mm, radius is 7.5mm; In conjunction with four concentric round belts of Fig. 2 vertical view, be reinforcement, thickness is 0.08mm+0/-0.01, and width is respectively near three concentric round belt 0.25mm of circle centre position, and the concentric round belt in outside is 0.50mm.
The present invention improves the oxygen permeability of soft corneal contact lens by the method for attenuate contact lense thickness, by strengthening circle, increase the intensity reducing because of attenuate contact lense thickness.Thereby accelerate the speed that patient's cornea recovers, improve visual quality, reduce the generation of postoperative complications.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention.Person skilled in the relevant technique, in the situation that not departing from technical characterictic of the present invention, can also make various conversion or modification; Therefore all technical schemes that are equal to thinking also should belong to category of the present invention, should be limited by each claim of the present invention.
Claims (3)
