Engineering research to answer Vicryl® tie questions - 29th Apr 2017

Donald Sinclair Donald (Don) Sinclair, a final year engineering student at the University of Canterbury in New Zealand, has spent his summer finding answers to several knotty questions. The Vicryl® tie, a knot of suture material that prevents aqueous draining into the unhealed bleb for several weeks, is an important technique for achieving even better outcomes in Molteno and Molteno3 glaucoma implant surgery. The Vicryl® tie reduces hypotony and reduces fibrosis in the bleb (13, 20).

Ophthalmologists have described a variety of methods for tying the knot and occluding the tube since the technique was first described in 1986. Don's study is the first to determine whether there is any evidence to support one method over another. Working with Dr Malcolm McKellar, an experienced glaucoma surgeon, Don designed a study to investigate the effect of type of knot, size of suture material and presence of a nylon stenting suture on the force a surgeon must apply to the suture material to occlude the tube. Don also determined the forces that would damage the tube.

When the data has been analysed, Don will be able to recommend occluding techniques that produce consistent and reliable occlusion with a low risk of damaging the tube. He and Dr McKellar plan to publish the research and the results will inform the recommendations in the Molteno and Molteno3 surgical guides

East Timor Eye Program treats glaucoma with Molteno3® implants - 6th Apr 2017

Tasmanian ophthalmologist, Associate Professor Nitin Verma, founded the East Timor Eye Program in 2000 when East Timor (Timor Leste) attained independence after a devastating war. The initial aim was to bring eye care from overseas to more than a million East Timorese who were without eye care services, now the focus is on training East Timorese eye care professionals so that the country itself has the resources to eradicate preventable blindness by 2025.

On his most recent trip to the National Eye Centre in Dili, Assoc Prof Verma and senior registrar Dr Valerio Andrade treated patients with severe glaucoma by implanting Molteno3 SS-185 glaucoma implants. The Molteno3 SS-185 is the most versatile glaucoma implant and "incredibly easy to use".

MOLTENO Ophthalmic is delighted to support the work of the East Timor Eye Program and is grateful to Designs for Vision, who distribute MOLTENO implants in Australia, for arranging the donation.

MOLTENO Ophthalmic will be at RANZCO 2017 with exciting new research findings. - 4th Apr 2017

MOLTENO Ophthalmic will be at RANZCO 2017 in Paihia, 12-13 May, at stand 17. The stand will display the world-leading range of Molteno and Molteno3 glaucoma implants, including the latest development, the Molteno3 S-series (SS-185mm2 and SL-245mm2).

Molteno3 S-Series
implants are:
  • easier to use
  • quicker to insert
  • gentle on vulnerable tissues
  • deliver double-plate perfomance with single plate simplicity.
The MOLTENO stand will also feature the popular Vicryl® tie 'wetlab' a great opportunity to practice an important technique in a safe, non-surgical setting.

Research on safely and effectively occluding the tube with a Vicryl® tie has just been completed. The effect of knot type, suture size and the presence of a nylon stent in the tube lumen is better understood and will be shared with conference delegates for the first time. 


MOLTENO bone graft research shares in $12 million grant - 29th Sep 2016

SilverBone research: antibacterial bone graft for dental surgery and implantology MOLTENO Ophthalmic's bone graft research and development project was boosted by a substantial grant from the New Zealand Government's Endeavour Fund. The project builds on MOLTENO Ophthalmic's established bone-derived products, the M-Sphere orbital implant and the MoaBone surgical implant and, working with the University of Otago's School of Dentisty and the Chemistry Department, aims to develop 'SilverBone', a bone graft material with antibacterial properties. The fund allocations were reported in the Otago Daily Times

Prof Warwick Duncan is leading the team of researchers. He has extensive experience with research into bone regeneration and is an expert on in-vivo testing of bone graft materials. The development and widespread use of dental implants has led to considerable interest in better bone grafting materials for use in the mouth, where there is a significant risk of bone resorbtion and graft infection. This exciting project aims to solve both the infection and resorbtion problems using the combined resources of MOLTENO Ophthalmic and the University of Otago.

Molteno3® glaucoma implants contribute to the vision-saving work of the John Fawcett Foundation - 3rd Aug 2016

Prof Bill Morgan (University of Western Australia) travelled to Indonesia recently to support the charitable work of the John Fawcett Foundation, taking with him Molteno3 SS implants donated by MOLTENO Ophthalmic. Prof Morgan has been working with two local glaucoma surgeons, Dr Agus and Dr Rahayu, and had shown them the technique for Molteno3 glaucoma valve implantation on a previous trip.
On this visit Prof Morgan supported Dr Rahayu while she operated on a particularly challenging case. Prof Morgan takes up the story: “The patient had ciliary block-induced chronic angle closure with a pressure of 40 mmHg. The patient had already undergone YAG laser iridotomy and successful cataract extraction two months prior because of the angle closure. Additionally, the patient was already totally blind in the other eye from chronic angle closure glaucoma and had an acuity of 6/24 in the left and only eye.”
“It was surprising to see ciliary block in a patient who was already pseudophakic but I have seen this before and have presumed the cause to be a thickened anterior hyaloid face. So in the surgery I assisted one of the senior glaucoma surgeons, Dr Rahayu, whilst she performed the Molteno3 SS valve implantation, scleral flap and other parts of the tube surgery, giving her some guidance along the way. I performed a core vitrectomy through a corneal incision cutting a periphery iridectomy, zonulectomy, hyaloidectomy and that relieved the ciliary block.
That particular patient was an excellent teaching case for some of the physiological principles of angle closure and it was a difficult technical case but, fortunately, went very well and the next day the pressure was down to 20 mm/Hg with a visual acuity of 6/18.”
The patient and medical staff of Indera Hospital were extremely pleased and appreciative of the donation of Molteno3 SS implants for this charitable work.

A very early Molteno glaucoma implant, used in the 1960s.

Fifty years ago, Anthony Molteno, training to be an ophthalmologist, operated on a toddler with a previously untreatable type of glaucoma (buphthalmos) and inserted the plate implant he had developed. The surgery was successful and his implant transformed the management of severe glaucoma. The Otago Daily Times marked the 50th anniversary with a full-page feature celebrating Anthony Molteno's remarkable career of research and innovation, always focused on the goal of saving sight and making life better for his patients and others all over the world. 

MOLTENO Ophthalmic staff also starred in the article with Production Manager, Roslyn Pearce, photographed at the microscope working on a third generation Molteno3 S-series implant, the most technologically advanced glaucoma implant and a descendant of that very first Molteno glaucoma implant from fifty years ago. Some features of the early implant are recognizable in the Molteno3 implant such as the implant plate that prevents the tissues forming a hard cap of scar tissue over the end of the draining tube and the suture holes used to secure the implant in place. Other features are recent developments, particularly the technologically advanced oval primary drainage area which is unique and has two functions:
  • reduces the risk of hypotony (abnormally low intraocular pressure) and
  • promotes natural anti-inflammatory and fibrodegenerative processes that keep the bleb (the tissue around the implant that drains excess fluid) functioning long term. 

Chief executive, Nina Molteno, reported that the company was "focusing on spreading the word about the high success rate of Molteno glaucoma implants...[and] would continue to support glaucoma research, while also working on new research and development projects..".


Glaucoma surgical skills training at MOLTENO Ophthalmic's RANZCO stand - 3rd Jun 2016

Drs Yu-Chieh Hung, Delia Wang and Mimi Chiu learning a surgical technique at the MOLTENO Ophthalmic stand, RANZCO May 2016 Ophthalmology registrars, interns and nurses had fun developing surgical skills for Molteno and Molteno3 glaucoma implantation at the company's stand at a recent conference in Dunedin:

  • occluding the silicone tube with a 5.0 braided polyglactin suture (Vicryl®),
  • testing tube occlusion using a 30G anterior chamber (Rycroft) cannula and 
  • making a relieving slit (Sherwood slit) in the occluded tube with a 20G corneal/scleral knife (1.3mm V-Lance®).
These surgical techniques, which are carried out under an operating microscope, have been shown to improve success rates and reduce the risk of complications of Molteno glaucoma implant surgery (13, 16). The occluding suture temporarily blocks the flow of aqueous from the eye while the drainage bleb starts to heal, an approach called 'delayed drainage'. At the same time the relieving slit allows aqeous to escape if the IOP gets high while waiting for the polyglactin suture to dissolve. Despite the challenges of working though a microscope, the trainees learned quickly and seemed delighted by their new mastery of the three skills.

V-Lance® is a trade mark of Novartis.
