Definitions

  • the present invention is a lens for optical correction with a black painted central part with a central transparent area (pinhole), this lens being spherical or spherical-cylindrical and being applied as a contact lens.
  • the present invention is in the field of ophthalmology.
  • This estenocherico hole also called pinhole or still of PH, is an opaque disc with a hole. It is used in the refractor Green when a refractive error is suspected to test visual acuity. This is done without ophthalmic lenses (spherical and cylindrical). Its mechanism is to temporarily remove refractive errors, such as myopia, through the passage of light through the center of the cornea and lens - decreasing aberrations and increasing the depth of focus of the eye; all by diminishing the circular blurs of the blurred light brushes that overlap the retina.
  • AcuFocus KAMRA Inlay is an intraestromal corneal implant used as an option for correction of presbyopia.
  • the technology is based on the principle of depth of focus produced by the pinhole and patent was requested on 08/27/2012 (US 20120245683A1).
  • XtraFocus was developed by the Brazilian ophthalmologist and researcher Cláudio Trindade and is included in the list of the most important innovations in Ophthalmology in 2014. XtraFocus must be surgically implanted within the eye and is capable of improving the vision of people with disorders of the eye cornea.
  • JP3179308 discloses correction lenses for presbyopia to be used directly on the cornea, i.e., they are used as a contact lens.
  • Said lenses are circular and have a colored portion in the central region and a pinhole in the center to increase the depth of focus.
  • the lens is formed by a pair of divided lenses that surround a colored limb, this factor makes the lens thicker and requires more steps for its manufacture, and may present problems such as separation of the pair of lenses.
  • US2005134793 discloses multifocal lenses containing a pinhole for correcting presbyopia.
  • the lens described comprises two refractive fields, one for distance vision and another for near vision, the area between the refractive fields being opaque, absorbing 75 to 100% light.
  • the document does not disclose different embodiments of the steppe bore to fit the patient's visual condition.
  • EP2455799 discloses a gelatinous lens to be used as a contact lens, containing an aseptic hole in the center of a zone capable of barring light input and increasing the depth of focus. Also disclosed is the presence of a plurality of smaller holes around the pitcher hole, it being commented that said holes improve the night and peripheral vision. However, the document does not disclose different embodiments of the steppe bore to fit the patient's visual condition.
  • the invention allows an excellent correction of presbyopia, corneal aberrations and media opacity. Especially in the area of corneal aberrations and media opacity, little has been developed in relation to contact lenses.
  • presbyopia lens solutions available today is the use of a lens in one eye for near and the other eye in the distance. This disposition of lenses in many patients causes haze and discomfort, making it impossible to use.
  • the differential of the proposed lens in presbyopia is that it allows a greater naturalness of vision. This is achieved by placing a lens away in one eye and in the other the lens of the present invention. This lens, through a spherical and or cylindrical lens association, calculated from the patient's diopter and age, and the depth effect of the pinhole allows a more physiological view.
  • the mechanism that promotes this result is the ideal calculation of the spherical and or cylindrical lens in association with the chosen design (lens painting), allowing the improvement of the near and intermediate vision while minimally affecting the vision from afar.
  • the present invention features a pinhole design which allows the patient to have a multifocal view, by depth of focus, and a good visual field for daily activities.
  • the present invention aims to solve the problems encountered in the state of the art from the development of an optical correction lens with a central part painted black with a central transparent area for correction of presbyopia and other optical problems .
  • the present invention features an optical lens kit comprising a first lens for optical correction as described herein and a second conventional contact lens.
  • the present invention provides a vision correction process comprising a step of applying a lens for optical correction as described in this report in a first eye and a conventional contact lens in a second eye.
  • inventive concept common to all claimed protection contexts is the development of a lens having novel properties for correction of presbyopia and other optical diseases in addition to an optical lens kit and a vision correction process comprising said lens.
  • Figure 1 shows a conception of a prototype of said lens.
  • Figure 2 shows a second prototype design of the lens of the present invention.
  • the present application relates to an ocular contact lens, which can be produced in any material (for example, silicone hydrogel).
  • the lens may be rigid, gas permeable, gelatinous, mixed, toric, scleral, cosmetic, prism or prismless, or therapeutic and exhibiting any type of curvature, depending on the need and the cornea of the patient.
  • This lens should have a painted part of black, circular and opaque with a central transparent area (optical zone).
  • This design has the function of filtering the peripheral rays giving a pinhole effect, being able to present 4 to 10 mm of diameter.
  • optical zone transparent part
  • This optical zone, central and transparent region of Figure 1 may have its power on the front or rear surface of the lens, being in the patient's central view axis.
  • the spherical and / or cylindrical powers associated with the depth of focus produced by the painting allow the vision from far, near and intermediate.
  • our lens has only one optical zone (optical power).
  • the present invention may be better understood as an optical correction lens having a central black painted part with a central transparent area, this lens being spherical or spherical-cylindrical and being applied as a contact lens.
  • the diameter of the central part painted black may vary from 4mm to 10mm and the transparent area inside this central portion may have one or more of a non-circular shape such as oval, elliptical, star or various shapes, such as transparent circles for example, arranged within the same opaque area.
  • conventional contact lens refers to a contact lens with only degree of vision correction.
  • the present invention features an optical lens kit comprising a first lens for optical correction as described herein and a second conventional lens.
  • the present invention provides a vision correction process which comprises applying a lens to optical correction as described in this report in a first eye and a conventional contact lens in a second eye.
  • the prototype shown in Figure 1 consists of a 14.2mm diameter, 6mm diameter opaque and opaque central jelly lens with a clear oblong center area measuring 1, 6mm wide and 2.4mm in one embodiment the transparent central area comprises oval design.
  • the prototype shown in figure 2 consists of a jelly lens having a painted black circle having three tangent and transparent circles.
