Definitions
- This utility model patent refers to an iris expander ring, which combines the function of dilating the pupil of patients who will undergo cataract surgery and vitreoretinal surgery in cases that do not show adequate dilatation for accomplishment of these two surgeries. In addition, there is no need for accessory incisions in the eye or the use of the Injector. to your.
- the present expander ring has been developed through which it is possible to carry out its implantation into the patient's ear and its removal through the same incision in which the cataract will be withdrawn and without the need for an injector. Therefore, four accessory incisions will not be required.
- the said ring has a circular shape with an opening in one of its parts.
- the s-inner portion âm u ⁇ o ⁇ mm It consists of alternating locking parts 7 in oiho ins, one the larger part in the upper region of the ring, followed by a smaller portion in the lower region, always following in this order.
- the ring may. more fully understood from the following detailed description, in accordance with the attached figures, where:
- FIGURE 1 is the top view of the dwarf
- FIGURE 2 is a longitudinal view of the ring.
- FIGURE 3 is a side view of the ane
- the aperture (1) of the expander ring can be seen. Through it the instrument will be introduced into the eye during cataract surgery.
- the upper iris caps 4 are alternating with the lower parts 5, the first being larger than the lower iris.
- the inner diameter of the ring 2 and its height 3 can also be seen, .
- the implantation of the ring can be performed by the same incision that is made for cataract removal. You can start the introduction by any of the .part .abert s.do jnstrumaata-
- the ring may be inserted into the human eye using a simple tweezer already used in cataract surgery. Once inserted into the eye, a hook should be used to manipulate cataract lenses. This hook must be inserted into each hole 8 in order to connect each of the upper and lower fittings 5 in the patient's iris so that their pupil is fully dilated by the ring.
- the cataract surgery is instituted with posterior implantation of the intraocular lens as usually occurs in this type of surgery. After lens implantation, the lens gain is again used.
- lens manipulation for disconnecting each of the upper grooves are lris (4) and lower (5) to then remove the ring of the human eye , and then releases the cirurgia-.
