Description

DESCRIPTION

Keratoscope device for a microscope

Scope and prior art

Current ophthalmic analysis devices and procedures of this type are of utmost importance in ophthalmology. Thanks to the use of these devices and the associated procedures, it is possible to calculate where to perform the corneal incisions in cataract ophthalmological surgery, among other ophthalmological surgeries, as well as calculate the positioning of intraocular toric lenses (that correct astigmatism), phakic lenses, assistance in corneal surgery, relaxing corneal incisions, corneal incisions to compensate or reduce astigmatism, centering of intraocular lenses in cataract surgery, as well as assistance for sizing, guiding and centering of capsulorexis in cataract surgery.

At present, in the ophthalmological sector and more specifically, in the field of cataract surgeries, implantation of toric lenses, performance of capsulorexis in cataract surgeries and corneal surgical procedures, relative positioning during surgery is important.

Regarding cataract surgery and the implantation of toric intraocular lenses, the positioning of this type of lens in a certain position is very important since said intraocular lenses must have a specific orientation so that they optically fulfill their function. Another type of toric lenses that must have a specific positioning are ICL or IPCL toric phakic lenses, among other toric lenses, which would benefit from a guidance and positioning system for their implantation.

Currently, the guidance and positioning systems used for the implantation of toric lenses are of several types:

1. Manual slit lamp marking system using a marker or special ink for ophthalmological use. This system marks from the main axes (0 °, 90 °, 180 ° and / or 270 °) to later adjust in surgery by means of a Méndez ring that has the ability to adjust the degrees intra-surgically or other devices that can perform previously the marks for the subsequent surgical implantation of the toric lens;

2. Marking systems with a special marker on the cornea, using a slit lamp, the positioning axis of the toric intraocular lens to be surgically implanted. Said markings are assisted by the degree marker coupled to the slit lamp;

3. Digital guidance systems, more precise and expensive, capable of recognizing the different anatomy of the eye in different devices used in consultation, such as corneal topographer, biometers, etc., and which subsequently recognize the positioning of the eye surgically with high precision compensated for the cyclotorsion that occurs when the patient is positioned horizontally. Said devices project some degree projection marks, normally in an associated camera, by means of which the different types of toric lenses or lenses that must be placed in a specific position (type ICL, etc.) are positioned. There are different models marketed as The VERION ™ Imagene Guided System ALCON or Intraoperative Guidance System ORA®, among other guidance systems or Polaris Keratoscope.

Additionally, the so-called keratoscopes are known that project light beams on a circumference on the corneal surface and are reflected by the corneal surface, thanks to which it is possible to adjust the corneal sutures in penetrating keratoplasties, visualizing how the luminous circumference is deformed in the corneal surface depending on the tension of the different suture points in the cornea.

Object of the invention

Starting from the state of the art described above, the present invention has the objective of developing a keratoscope device for coupling to a microscope, for example, an ophthalmic microscope which is easy to manufacture and simple to operate by means of which both the precision of measurement and the speed of measurement can be increased.

The invention is based on the idea of combining the projection of at least two concentric circular light sources on the corneal surface, but which, unlike known keratoscopes, are mobile relative to each other and also, additionally, project light sources according to a diametrical line. that can be angularly displaced with respect to at least one of the circular light sources, this using a device that can be attached to microscopes, which do not necessarily have to be ophthalmic microscopes.

In this way it is possible to calculate the cyclotorsion, by projecting the corneal marks arranged in the concentric circles with different marks, we can position said projections and rotate them, in order to, in this way, be able to align them with references or ocular marks and thus align said projections circular with marks.

Furthermore, it becomes possible to calculate the relative position using the movable radial projection lights, since by being able to rotate about the axis, the relative position of the projection of the radial lights in a specific degree position can be precisely calculated. This is useful in calculating toric intraocular lens positioning, corneal incisions, calculating cyclotorsion in strabismus surgery, and the like.

The device according to the invention provides a capsulorexis guidance system. With the projection of the circumference of light sources of greater radius, the ability to guide the capsulorexis is provided , as well as to calculate or assist the size of the same in a relative way.

Furthermore, with the keratoscope device of the invention it is possible to center multifocal intraocular lenses during surgery. Indeed, the projection of circular light sources, for example, smaller in size, has the utility of being able to center diffractive multifocal intraocular lenses, since they present concentric circles, which we have the ability to align with the smaller circular projection of the keratoscope.
