If you order this product, you receive 12 eyes in 6 containers within a moist environment to keep our eyes fresh for at least one year. This is necessary because our eyes are ready to use as the eyes on the patient table. As you can imagine, the quality suffers if you keep the eyes too long outside of the container. Also, you should protect the containers and the eyes from heat and sunlight, if possible.
Our Eye 4 VIT/CAT is basically a whole eye with lens and vitreous. This eye is very comprehensive in terms of holistic simulation. You can simulate all phaco and vitrectomy simulations from our other products and also combined stuff. Several operations can be simulated with such a configuration: clear corneal incision, multiplanar self-sealing incision and suturing, performing of the rhexis, hydrodissection, use of OVD (LINK), Nucleus Disassembly one- and two-handed, divide and conquer, chop techniques (LINK), ruining the capsule bag in case of wrong behaviour, implantation of IOLs, ICLs and add-ons, explantation, producing of pars plana vitrectomy ports (Microincision Vitrectomy Trocars), removal of clouded vitreous simulation with staining solution, vitreous staining (LINK), membranectomy, fluid/air exchange, air/gas exchange, silicone oil injection, photocoagulation, vitreous floaters, vitreous hemorrhage simulation with staining solution (LINK), removal of intraocular foreign bodies (IOFBs).
But the important thing is this: You can induce incidental capsular lesions with dropped nucleus. This is possible because you have a fragile posterior capsule and the whole vitreous behind.
You can choose between several different options:
Cataract: Soft or Hard
We recommend the use the hard cataract because this one is better for training phaco techniques like divide and conquer, chop techniques. (LINK)
Rhexis. 5mm and 6mm
If you have no lens in the eye, somebody took it out. This usually happens in conditions with an regularly explanation and therefore you have a rhexis. We are able to punch all sizes of holes but found these two sizes most practicable. As always, if you need something else, please contact us. (LINK)
Iris: 5mm, 6mm and 7mm
Our iris is mostly for a more realistic behaviour but you can also use it for simulating a non-dilating/not fully dilating, or inoperative floppy iris syndrome. Our iris material is slightly firmer, therefore we start already with a diameter of 5mm because Tension Rings or other pupil dilators would not spread apart a 2mm artificial iris.
Sometimes we are not in the best mood or our machines are getting sloppy. This can result in a lower quality as we like to offer you. In very few cases you can get hold of the manufacturer of such products. With us you are lucky, because if you are not happy with the quality of our product, just contact us and we will not only swap it, no, we will replace it doubly.
ILM Peeling: Yes or No
Use a very fine forceps to peel the ILM from the underlying retina. We have no epiretinal membranes or posterior hyaloid. Also the ILM foil is not very realistic but you learn a lot, especially the instrument handling and the feeling of depth.
Dropped Nucleus: Yes or No
This complication can occur at any stage of phacoemulsification (i.e. during hydrodisecction, sculpting or nuclear segment removal). It can even occur during phacoemulsification done by experienced surgeons. With the Dropped Nucleus option you can train this very common accident by using PPV. (LINK)
Foreign Body: Other, Magnetic or No
Very common operation to find a metal flake or chip in the posterior segment. We also have non-magnetic round coloured objects. Recovery of such objects does not take very long, but it helps a lot to get the feeling of depth and three-dimensionality.
