First RGB LED Light Source for Ophthalmic Surgery

Introducing the latest innovation by Geuder: SOLEA, an LED light source for endo-illumination capable of displaying an incredible 16.7 million colors of the visible spectrum. Built with exclusive RGB technology, it offers enormous freedom in color composition and visualization of the finest tissue structures at color temperatures of 3,500–6,000 K. With a maximum luminous flux of 45 lumen, the operating field is perfectly illuminated, while the phototoxic amount is low – thanks to an integrated retinal protection mode that can completely deactivate the blue LED. In this regard, the benefits are two-fold: i) it increases patient safety and ii) it enables longer illumination times with comparable light intensity. And thanks to the narrow-band spectrum of the LEDs, additional UV or IR filters are not required. Moreover, with three independent fiber optic outputs and an LED service life of up to 60,000 hours, the Geuder SOLEA is a truly sustainable light source.

The clear benefits to vitreoretinal surgeons include real color rendering for maximum tissue distinction through complementary contrasts in the RGB color space. Existing applications of blue and amber light can now be expanded to include applications in the green light spectrum, enabling easy differentiation of vascularization in the posterior segment. For example, in the case of stained ILM peeling with Brilliant Peel® Dual Dye, the colored tissue appears significantly more intense under green light. Since the introduction of one- and two-color LED technology, blue light has increasingly been used for the visualization of vitreous body remnants. Notably, the Geuder SOLEA has the unique ability to reduce the phototoxic amount of blue light through additive color mixing of all three primary colors – red, green and blue – to obtain adjacent colors, such as turquoise or purple, which offer the same visual effect. RGB technology should make Geuder’s new endoillumination system the surgeon’s first choice for unrestricted control and extended application possibilities in intraocular illumination.

Implants for Retinal Detachment – The Portfolio of GEUDER AG

For many years silicone implants have been wide spread for the surgical treatment of various indications of retinal detachment. It is a very safe and, at the same time, a very cost-effective treatment which, in comparison to intraocular methods, reduces infection risks and other complications and in this way improves patient safety. Due to many years of market experience, the effectiveness and safety of these implants could be ensured.

Many experts in ophthalmology use GEUDER implants as their preferred method when treating retinal detachments in phakic eyes. The treatment with silicone implants is also considered to be the best method for the treatment of inferior retinal tears.Furthermore, by using the implants, the risk of endophtalmitis and surgically induced cataracts can be reduced significantly.

For more than 65 years, GEUDER has been offering innovative products in ophthalmology and has been producing instruments of highest quality, precision and reliability. Of course also special instruments for the safe and comfortable implantation of silicone implants are produced.

The resulting wide-ranging product portfolio of GEUDER AG allows our customers a very good treatment of retinal detachments with products from one hand – it’s worth more than just a glance:

F4H5 WashOut Improves Surgical Outcomes in Patients With Silicone Oil Induced Glaucoma

Interview with Prof. Walid Zbiba (Tunisia)

We asked Prof. Walid Zbiba (Head of Ophthalmology at Mohamed Taher Maamouri Hospital, Nabeul, Tunisia and Assoc. Prof. in Ophthalmology at Faculty of Medicine of Tunis, Tunisia) about his experience with our award winning F4H5 WashOut solution. He explains why F4H5 is useful in preventing silicone oil induced glaucoma, especially if silicone removal is done early before structural damage to the trabecular meshwork occurs. Read why and watch how Prof. Zbiba is using it for all patients undergoing silicone oil removal and especially those with persistent silicone oil droplets in the anterior chamber or sticking to the IOL or the retina. Using the Geuder/Fluoron F4H5 WashOut improved his final surgical outcomes mainly in patients with silicone oil induced glaucoma, concluding that F4H5 is simply safe, efficient and easy to use and should be used as standard in every silicone oil removal procedure.

As cornea transplantations are considered to be elective during the corona crisis the waiting list of patients has more than doubled, not only in the Netherlands. While only urgent cases, like (impeding) perforations and bullous keratopathies are currently being treated, safe approaches for testing donors and recipients need to be established in order to reduce the growing backlog of other cases, like the Fuchs endothelial dystrophy (FED). There are ways to resume DMEK and other “elective” corneal transplantation techniques. Learn more about the Dutch approach from the head of ETB-BISLIFE cornea bank:




The Impact of COVID-19 on Cornea Transplants in Germany

Interview with Martin Börgel (DGFG) und Dr. Silke Wahl (KK Saar)

Compared to the situation in the U.S.A. and Italy where corneal transplantation dropped down to 5-10% of the normal volume, Germany is still performing at about 50%. But it also means that 50% of the transplants are lost due to limited storage time, bringing up the same ethic discussion as in the U.S. and Italy on how we can justify a waste of grafts to donors and their families?

The waste is even less reasonable considering the fact that hospitals in Germany are not overloaded and donors and their environments are thoroughly screened for COVID-19, disqualifying all suspicious donors. As there is currently no evidence that SARS-CoV-2 can be transmitted through the transplantation of tissue and tests are not validated for post-mortem donors, all precautionary measures are in effect.

But the limiting factor are not rejected donor tissues due to screening or other precautionary measures - it is rather the imposed reduction of elective surgeries. Some of the patients in need of a corneal transplant might be elective now but they “will become urgent cases in a few weeks or months” as Martin Börgel (DGFG) said. This will increase waiting times for patients and organizational efforts throughout summer and fall.

The Impact of COVID-19 on Cornea Transplants in Italy

Interview with Dr. Diego Ponzin, Medical Director of FBOV

Almost 90% of all corneal transplants were cancelled or postponed worldwide. Patients and waiting times for surgeries are piling up, while many donor grafts are wasted, because they cannot be stored for much longer than a month. The precautionary measures taken are vital, but better solutions to solve the shortage of supply and treatment need to be addressed soon. Studies assess the risk of SARS-CoV-2 transmission through tears differently, but screening donors and recipients for COVID-19 should give enough certainty to perform cornea tranplant surgeries at a required level again.

The interview with Dr. Ponzin, Medical Director of the Veneto Eye Bank Foundation in Venice, Italy, gives us the insight of an expert in the specific Italian situation, where these procedures almost came to a halt.

The Impact of COVID-19 on Cornea Transplants in the United States

Interview with CorneaGen CEO Monty Montoya

Monty Montoya, CEO of CorneaGen (U.S.A.), the largest supplier of corneal tissue in the world, talks about the impact of COVID-19 on cornea transplants in the U.S. It is the first interview of a cornea bank interview series conducted by GEUDER and CAKE magazine.

After the WHO, CDC, FDA, GAEBA and EEBA have sent out precautionary measures regarding COVID-19 we were curious about the impact it had on cornea transplants. First because cornea transplants can restore the sight of blind patients, which is invaluable, and second because DMEK instruments and techniques are one of GEUDER’s specialties. So we wanted to learn from leading experts of eye banking what effect the crisis has on keratoplasty surgeries now and in the near future.

In the following video Mr. Montoya shares his insights on

  • Harvesting and deliveries of human corneas and DMEK grafts
  • Testing donors and recipients of corneal grafts for COVID-19
  • The shortage of supply and waiting times for corneal transplantations
  • Changing the cell culture medium to overcome the COVID-19 threat in the future

Transscleral Fixation of Dislocated 3-Piece IOL

with Hattenbach Microneedle (2mm) and Bimanual Microsuturing Technique (by Hattenbach)

A dislocated IOL is a challenging situation for the surgeon. The repositioning needs to be long lasting with a good visual outcome for the patient and as atraumatic as possible. In this video Prof. Hattenbach (Ludwigshafen, Germany) performs a modified transscleral technique where the sutures are tied and haptics are fixated inside the anterior chamber (AC).

His bimanual intraocular micro suture technique is precise and less traumatic than other closed-eye procedures. Two small 21G paracenteses reduce the risk of induced astigmatism. An ONATEC® Hattenbach 2mm micro needle and GEUDER® Hattenbach hybrid instruments allow for flexible and safe maneuvers within the AC. The GEUDER® tying forceps, needle holder and scissors are especially designed for AC microsuture procedures: The 25G angled tips enable micro maneuvers like in vitreoretinal surgery, while the short handle grants optimal ergonomy, flexibility and control.

ONATEC‘s ONALENE® monofilament polypropylene thread is highly tear-resistant and durable for long lasting fixations.
