Abstract
The utility model discloses an improved corneal contact lens for treatment. The improved corneal contact lens comprises a corneal contact lens (1), wherein a plurality of micro-pores are formed in the non-optical area (4) of the corneal contact lens (1) and arranged uniformly in an annular array shape, and have effects of ventilating, relieving corneal hypoxia, storing a liquid medicament and slowly releasing the liquid medicament; and the effects of drainage and substance exchange can be achieved according to the difference of the permeation pressures on the two sides of the each micro-pore. The corneal contact lens has the largest amount of medicament load as possible; the slow-release process of a medicament can be controlled; the shape and the transparency of the corneal contact lens can be kept all the time during use; during storage and transport, the medicament-loaded corneal contact lens can keep stable; and the air permeability of the corneal contact lens cannot be influenced during use.
Description
Technical field
The utility model belongs to medical instruments field, is specifically related to a kind of modified form treatment and uses contact lens.
Background technology
Cornea is the first road barrier of eye table, is again important refractive media, and cornea receives wound or produces pathology, will bring pain and have a strong impact on quality of life to the patient.For the treatment of keratopathy, mainly concentrate on drug therapy and operative treatment at present.The intractable ulcers of the cornea that infection caused such as some bacteriums, fungi, virus; The cornea large tracts of land is stripped off due to cornea wound and the soda acid burn in addition; Cause behind the outer ocular operation such as pteryium excision the corneal epithelial defect area big, repair slowly, make that patient's eye susceptible inflammation and irritation are serious.How to seek a kind of not only simple and easy to do, but also effective and rapid ground promotes the corneal epithelium reparation, the method that alleviates the patient suffering is the problem that the clinician is inquiring into always.
The number of users of contact lens has reached about 1.5% of world population sum at present.Analyzing through relevant literature search and Meta that the prompting soft corneal contact lens uses in keratopathy is a kind of have clinical value, economical and practical methods of treatment; But soft corneal contact lens is defectiveness also: it is not enough that its oxygen permeability reaches the tear exchange inadequately; Adsorbed by albumen precipitation easily; In view of the existing shortcoming of existing contact lens, need make improvements.The structure of general contact lens comprises: Optical Region (3) and non-optical zones (4), Optical Region are that (the central radius-of-curvature in back surface of haptic lens is called basic arc to basic arc, and radius-of-curvature is long more, and basic arc is smooth more; Radius-of-curvature is short more, and basic arc is precipitous more) place lens area, general range is 7.0-8.5mm, can cover pupil basically.Non-optical zones (inside surface is a circumference arc), the lens surface periphery is referred to as circumference arc around each arc of basic arc.Circumference arc is from inwardly becoming more smooth successively outward.The side view of contact lens as Fig. 1 is.
The utility model content
The purpose of the utility model is to provide a kind of modified form treatment to use contact lens.
The purpose of the utility model can realize through following technical scheme:
Contact lens is used in a kind of modified form treatment, comprises contact lens, and the non-optical zones of said contact lens is provided with a plurality of micropores, and described micropore circular array shape is evenly distributed.
Contact lens is used in above-mentioned modified form treatment, and it is that described micropore is the bending hole.The effect in bending hole is to retain soup, and makes soup reach slowly-releasing, can increase the oxygen transmission rate of contact lens in addition, alleviates the cornea anoxic.
Contact lens is used in above-mentioned modified form treatment, and it is that the epimere center line of said micropore and the hypomere center line of said micropore do not overlap.
Below be the function introduction of modified form treatment: 1, on the circumference arc of contact lens, stamp several micropores with contact lens; 2, the size of micropore, spread geometry and density range are suitable; 3, the effect of micropore is to breathe freely, and alleviates the cornea anoxic; 4, micropore can be stored soup and play slow releasing function; 5, according to the difference of the osmotic pressure of micropore both sides, can play the effect of drainage and mass exchange.
The beneficial effect of the utility model:
1, has maximum drug loading amount as far as possible;
2, the slowly-releasing process of medicine can be controlled;
3, can keep its shape and the transparency all the time in the contact lens use;
4, in storage and transportation, it is stable that the contact lens of carrying medicament can keep;
5, do not influence the gas penetration potential of contact lens in the use, and the thickness of contact lens is easy to accepted by the patient.
Description of drawings
Fig. 1 is the sectional view of general contact lens.
Fig. 2 carries out the vertical view of novel contact lens for this.
Fig. 3 carries out the part sectioned view of novel contact lens for this.
Embodiment
As shown in Figure 2, contact lens is used in a kind of modified form treatment, comprises contact lens 1, and the non-optical zones 4 of said contact lens 1 is provided with a plurality of micropores 2, and described micropore 2 circular array shapes are evenly distributed.As a kind of preferred version, described micropore 2 is the bending hole, and the epimere center line of promptly said micropore 2 and the hypomere center line of said micropore do not overlap (as shown in Figure 3).The effect of micropore 2 is to breathe freely, and alleviates the cornea anoxic; Micropore 2 can be stored soup and play slow releasing function; Difference according to the osmotic pressure of micropore 2 both sides can play the effect of drainage and mass exchange.
Claims (3)
1. contact lens is used in a modified form treatment, comprises contact lens (1), it is characterized in that the non-optical zones (4) of said contact lens (1) is provided with a plurality of micropores (2), and described micropore (2) circular array shape is evenly distributed.
2. contact lens is used in modified form treatment according to claim 1, it is characterized in that described micropore (2) is the bending hole.
3. contact lens is used in modified form treatment according to claim 2, it is characterized in that the epimere center line of said micropore (2) and the hypomere center line of said micropore do not overlap.
