Definitions

  • the present invention relates to a surgical tool for eye surgery.
  • the invention relates to a tool for assisting with the implantation of a toric intraocular lens (IOL) for correcting astigmatism, typically during cataract surgery.
  • IOL intraocular lens
  • Astigmatism commonly causes blurred vision for patients. It is usually due to an abnormality in the curvature of the cornea. This is referred to as corneal astigmatism. Corneal astigmatism is caused by differences in the radius of curvature in one principal meridian of the cornea compared to the other. These two principal meridians are located most commonly approximately at right angles to each other. One meridian is steeply curved (the steep axis) and the other meridian is less curved (the flat axis). To illustrate this difference, a soccer ball is spherical with equal radii of curvature. On the other hand a rugby ball has different radii of curvature.
  • Corneal astigmatism can be improved by certain surgical procedures, such as refractive laser surgery and incisional corneal surgery. However, some patients have an aversion to undergoing surgery (unless essential) and any surgical procedure does involve some risks. Furthermore, the improvement in astigmatism, may be unpredictable with these procedures and unsatisfactory outcomes may occur. [006] If a patient with corneal astigmatism also has cataracts, and cataract surgery is required, this is generally an opportunity for the patient to have both problems rectified with a single surgical procedure. Cataract surgery involves replacing the cloudy lens of the eye with an intraocular lens (IOL). The surgical technique most commonly used for cataract removal is called Phacoemulsification Surgery or Small Incision Cataract Surgery. The procedure involves the removal of the cataract and the implantation of an IOL through a micro incision (less than 3 mm wide).
  • IOL intraocular lens
  • An IOL is an artificial lens, usually formed of acrylic, silicone or PMMA
  • an IOL (polymethylmethacrylate), which has a similar shape to a natural lens.
  • An IOL is designed to reside inside the eye and focus light on the retina.
  • the chosen IOL inserted has a refracting power (dioptre), that will enable the patient to see clearly in the distance without spectacle correction.
  • Spectacles are usually required for close vision.
  • Other patients prefer to not wear spectacles for either distance vision or near vision, and multifocal IOLs can be inserted to achieve this.
  • clear vision without spectacles for distance, near or intermediate vision is not possible if a patient has significant corneal astigmatism, unless an IOL is chosen that also corrects for astigmatism (a toric 10L).
  • LASIK laser assisted in-situ keratomileusis
  • toric IOL implantation has become a preferred option for correcting corneal astigmatism in patients requiring cataract surgery.
  • the toric IOL implantation procedure requires only minor adjustments to normal cataract surgical techniques. It generally provides favourable results in terms of unaided vision and involves relatively low risks. Also, the desirability of this procedure has recently been further enhanced by the availability of an increasing range of high quality toric IOLls. It is estimated that up to 50 per cent of cataract patients have astigmatism that can be corrected by the implantation of a toric IOL.
  • the eye to be operated on is generally marked in the following manner. With the patient sitting upright and looking straight ahead, the limbus at 0°, 90° and 180° (usually) is marked with a skin marking pen. These marks act as the reference points during surgery.
  • the toric IOL is inserted inside the capsule of the eye and it is then rotated to the correct axis of orientation.
  • the toric IOL typically has 3 marking indentations at each hapticoptic junction. These marking indentations are aligned exactly with the steep corneal astigmatic axis, which can be in any axis from 0° to 180°.
  • a particularly suitable toric IOL for use in the above procedure is the AcroSofTM toric IOL.
  • This toric 1OL is an acrylic polymer that has ultraviolet and blue light filters and which has been FDA approved in the USA.
  • the intraocular alignment of the IOL is assisted by the use of an intraoperative toric axis guide instrument. Current toric axis guide instruments are formed of metal (typically stainless steel) and are re-usable. Examples of toric axis guide instruments currently in general use are the Mendez gauge, Dell marker and Nichamin instrument.
  • the toric axis guide instrument assists in determining the correct alignment of the toric IOL, which is rotated within the capsule of the eye, by the surgeon, until it is in exactly the correct orientation. To effect this, the toric IOL is typically rotated by the surgeon so that the marking indentations on the toric IOL align with the steep axis of corneal stigmatism (which has previously been determined).
  • toric axis guide instruments suffer from a number of shortcomings. For instance, such toric axis guide instruments need to be sterilized between operations before they can be re-used. Proper sterilization procedures take some time and this therefore involves significant 'down time' for each instrument. Where only a single such marker instrument is available, substantial delays between operations can occur, thereby reducing the efficiency of the surgeon and limiting the number of patients that can be treated during a particular operating session.
  • the toric axis guide instruments are quite expensive (hundreds of dollars) and, therefore, it is not common to have multiple toric axis guide instruments available in a surgery.
  • the above toric axis guides are also quite cumbersome to use.
  • the surgeon holds the toric axis guide by grasping the elongated handle with one hand.
  • a right handed surgeon would typically hold the handle of the axis marker in the left hand to check orientation and rotate the IOL with the right hand (and vice versa if left handed).
  • Due to the length of the handle (which is similar to the length of a tea spoon), the surgeon's hand is some distance away from the surface of the eye on which the annular-shaped ring is placed. This distance makes it somewhat awkward for the surgeon to control movement of the annular-shaped ring with high precision.
  • the above toric axis guides also have a tendency to break at the weak point where the annular-shaped ring joins the elongated handle. Once broken the instrument is rendered useless, as it often cannot be repaired.
  • the present invention is directed towards ameliorating some of the problems identified above. More particularly, the present invention is directed towards a convenient surgical tool for use during toric IOL implantation surgery to facilitate the alignment of the toric IOL with the patient's axis of corneal astigmatism.
  • a surgical tool for aligning a toric intraocular lens with an axis of corneal astigmatism of a patient, said tool including: a lower surface adapted to abut a patient's eye; an upper surface showing angle markings; a finger engagement surface, having a height of at least about 0.5 cm, adapted to be held by fingers of a surgeon when using the surgical tool; and eye viewing means through which the patient's eye can be viewed, wherein said angle markings are positioned so that, when said lower surface abuts a patient's eye, the angle markings are adapted to be located substantially about the limbus of said patient's eye and no more than about 0.3 cm above said limbus.
  • the limbus of an eye is the circumferential junction between the cornea and the sclera of the eye.
  • the abovementioned distance of about 0.3 cm or less between the markings and the limbus should be regarded as a preferred feature, not an essential one.
  • the finger engagement surface includes engagement enhancement means.
  • the purpose of the engagement enhancement means is to improve the surgeon's finger grip of the surgical tool and thereby reduce the likelihood that the tool will slip or be dropped during use.
  • the engagement enhancement means are typically selected from one or more of a ribbed surface, a roughened surface, a large surface area, and finger accommodating curves. It will be appreciated, however, that numerous other engagement enhancement means could be used for this purpose.
  • the finger engagement surface may simply be a peripheral surface of the surgical tool. As will be apparent, the height of the peripheral surface will need to be sufficient for the surgeon conveniently to be able to grasp the tool with the ends of his or her fingers.
  • the peripheral surface can have any number of cross-sectional shapes. However, preferred cross- sectional shapes include circular, octagonal, heptagonal, hexagonal and pentagonal. Alternatively or in addition to the above, the peripheral surface may have straightened or indented sections for being engaged by the fingers of the surgeon.
  • the peripheral surface extends upwardly from a peripheral portion of the upper surface.
  • the peripheral surface includes two or (more preferably) four portions which extend upwardly from the peripheral portion of the upper surface. These upwardly extending portions of the peripheral surface are preferably located equidistant from each other. As will be apparent, these upwardly extending portions constitute finger engagement surfaces which are adapted to be engaged by the fingers of the surgeon.
  • the eye viewing means can include a transparent plastic disk (or film) and the upper surface and lower surface are formed on opposed sides of the plastic disk (or film).
  • the surgical tool may be formed entirely of a transparent plastic. If the disk is transparent, the angle markings could obviously be located on the upper surface, on the lower surface or anywhere in between.
  • the eye viewing means can simply be a hole extending from the lower surface to the upper surface.
  • the angle markings are preferably located adjacent to the hole.
  • the hole is preferably dimensioned so that, at least, the cornea, iris and limbus of the patient's eye are visible when the surgical tool is placed upon the patient's eye.
  • the hole has a diameter of between about 8 mm and 25 mm.
  • the diameter of the hole is between about 10 mm and 20 mm.
  • a particularly preferred diameter of the hole is about 13 mm. It is particularly preferred that the circumference of the hole is dimensioned so that it is substantially the same as or slightly greater than the limbus of said patient's eye.
  • the upper surface may taper down towards the lower surface so that, when the tool is in use, angle markings located on the upper surface are very close to the limbus of the patient's eye, thereby minimising the potential for parallax error.
  • the angle markings on the upper surface of the surgical tool preferably include markings at 0°, 90°, 180° and 270°.
  • the tool further includes markings at 45°, 135°, and 315°.
  • the upper surface of the surgical tool has angle markings at 5° or 10° intervals between 0° and 360° (or from 0° to 180° and from 180° to 0°).
  • the lower surface and the upper surface of the tool are preferably on opposed sides of a disk having a thickness of less than about lcm (10 mm).
  • the thickness of the disk is preferably less than about 0.5cm (5 mm). Having a thin disk can help reduce the possibility of parallax error which would otherwise occur if there is a significant distance between the angle markings and the limbus of the patient's eye.
  • the disk is generally annular-shaped (although the outer perimeter of the disk need not be circular-shaped)
  • the lower surface of the surgical tool may be contoured, or at least include a contoured portion, so as to substantially conform with the contour of an eye.
  • the surgical tool described above can be formed of any suitable material.
  • a particularly preferred material is polymeric or plastic as it is cheap, light and easy to use.
  • the surgical tool is able to be made inexpensively and therefore the tool can effectively be disposable. This enables a surgery to stock a multitude of the surgical tools described herein. A significant benefit of this is that no time needs to be wasted in sterilizing the tool in between operations on different patients. A new surgical tool can readily be used for each patient. More patients can then be treated in a single operating session, thereby improving the efficiency of the surgeon and the operating theatre.

  • Figures 3 and 4 show a surgical tool in which the finger engagement surface 2 has end sections 5d which are substantially flat and which are significantly wider than the rest of the finger engagement surface. These end sections 5d also have a set of parallel ribs 51. The increased width of the end sections 5d and the inclusion of the parallel ribs 51 enhance the grip which a surgeon is able to achieve when holding the surgical tool in his or her fingers.

  • a contoured portion 7 which is contoured so as to substantially correspond with the contour of a patient's eye. This enables the surgeon to locate the surgical tool on or very near to the patient's eye when checking on the alignment of the toric IOL which is being (or has been inserted) into the patient's eye.
  • a particular benefit of this is that it enables the angle markings on the surgical tool (e.g. on the upper surface 1) to be very near to the surface of the patient's eye. This reduces the possibility of parallax error when determining the correct angle for properly aligning the toric IOL in the patient's eye.
