Independent study: significant time saving with Molteno3® GDDs compared to Baerveldt® Devices - 23rd May 2019

Dr Sheybani, lead researcher in study comparing Molteno3® and Baerveldt® devices

Ophthalmologists from Missouri, USA, updated the results from their comparison of Molteno3 and Baerveldt glaucoma implant surgery at the recent AGS Annual Meeting [1,2].  The independent study is ongoing and now includes 113 cases. Key findings were:
1.      Surgical time was more than 11 minutes shorter in the Molteno3 group [1]
2.      IOP, vision change and medication use were equivalent after surgery, despite the smaller area of Molteno3 implants.

In a subsequent interview by Dr Davinder Grover, lead investigator, Dr Arsham Sheybani, added that
1.    patient comfort is better during Molteno3 surgery
2.    Molteno3 implantation requires less manipulation of the extra-ocular muscles
3.    the more pliable Molteno3 tubes require only one relieving slit (compared to two slits in the Baerveldt tube) and
4.    Molteno3 surgical time was shorter despite residents and fellows (trainees and less experienced ophthalmologists) performing many of the surgeries.

This is the first reported study comparing surgical time between Molteno3 and Baerveldt devices. Shorter surgical time is better for the patient, saves surgeon time and significantly reduces costs: one more reason to choose the advanced Molteno3 glaucoma drainage devices for patients with severe or complex glaucoma.

World Glaucoma Week 2019 - 12th Mar 2019

World Glaucoma Week 2019 Early detection of glaucoma saves sight! World Glaucoma Week is a gentle reminder to have your eyes checked regularly. Guidelines suggest an eye check every 5 years from the age of 45. Start eye checks at a younger age if there is a family history or other risk factors such as steroid treatment. 

You may not know you have glaucoma as many types of glaucoma cause few symptoms. People are adaptable and the gradual loss of peripheral vision may not be noticed. Early detection and treatment can prevent losing vision to glaucoma.

Having a relative with glaucoma increases your chances of having glaucoma yourself. Remind family members to have an eye check. An eye check to detect glaucoma generally includes:

  • a test of the visual fields
  • measurement of intra-ocular pressures
  • an examination of the optic discs.
Don't delay, book an eye check today!

World Glaucoma Week is a joint initiative between the World Glaucoma Association and the World Glaucoma Patient Association.

Did you know? Historical facts about glaucoma surgery #1: - 11th Oct 2018

Absorbable suture occluding the tube of a Molteno3 implant

In the 1970s a two-stage surgery was developed to prevent hypotony [1]. In the first surgery the plate of the implant was sutured onto the globe beneath Tenon’s tissue, then, in a second surgery 8 weeks later, the tube of the implant was inserted into the anterior chamber (AC). Between the first and second surgeries a thin layer of collagen was laid down in the wall of the bleb (the tissues around the plate) [2]. When the aqueous started draining from the AC, up the tube and into the bleb, the thin layer of collagen prevented hypotony by acting as a flexible barrier.

Unexpectedly, the two-stage surgery also resulted in much less bleb fibrosis and better IOP control. Keeping aqueous out of the bleb for 8 weeks was very beneficial. This technique became known as ‘delayed drainage’.

When Vicryl™(polyglactin) sutures were developed, the two-stage procedure was replaced by a single surgery [3]. At the time of surgery a 5.0 Vicryl suture was tied around the tube, completely blocking all flow. 5.0 Vicryl dissolves after 4-6 weeks so there was a 4-6 week delay before aqueous started to drain into the bleb. This produced similar results to the 8 week two-stage procedure.

Vicryl is a trade mark of Ethicon Inc.

Molteno3 S-Series glaucoma implants launch in Greece - 16th Jun 2018

The 24th Greek Glaucoma Congress held in Athens was a hive of happy activity as ophthalmologists from Greece and further afield gathered to learn about new developments. Keynote speaker, Prof Mark Sherwood (Florida), an experienced Molteno3 surgeon, addressed the topics ‘Trabeculectomy versus Tube as Primary Procedure’ and ‘New Approaches to Glaucoma Surgery’. Greek surgeons are excited about the Molteno3 S-Series implants, particularly the versatile Molteno3 SS (185mm2) model.  Molteno3 S-Series implants are available from Erghani SA, a specialist ophthalmic distributor.
Erghani SA, in conjunction with Alfa-Intes and MOLTENO Ophthalmic, arranged high-level training in Bologna, Italy for leading glaucoma surgeons so that patients get the best outcomes from Molteno3 surgery. After very positive feedback, further training courses are planned to meet the demand.
Dr Nina Molteno, chief executive at MOLTENO Ophthalmic, travelled to Athens to train the Erghani staff and to meet with the Greek surgeons. She was very impressed by the enthusiasm and dedication of the ophthalmologists, nurses, administrators and the Erghani staff. Those working in government-funded settings are providing ophthalmic services to their patients on extremely tight budgets, yet the clinics were spotless, the staff friendly and the service seemed very efficient. MOLTENO Ophthalmic is proud to be helping such dedicated professionals to save vision and improve the lives of glaucoma patients.  

World Glaucoma Week 2018 - 20th Feb 2018

World Glaucoma Week: Eye checks save sight! Molteno Ophthalmic is proudly supporting World Glaucoma Week, March 11-17 2018. Glaucoma is the leading cause of irreversible blindness and currently affects 64 million people worldwide. Glaucoma is a progressive disease that damages the health of the eye, however, blindness is generally preventable if glaucoma is diagnosed and treated early. Many types of glaucoma cause optic nerve damage without the patient being aware of the resulting vision loss until it is advanced.
As we work to improve treatment options for those diagnosed with glaucoma, World Glaucoma Week is raising awareness of the importance of getting your eyes tested regularly. The industry standard is to check eye health every two years[1]. Checks for glaucoma are part of a standard eye examination by an optometrist or optician. The tests are not invasive and include a test of intraocular pressure (pressure inside the eye) and assessments of the visual field and optic nerve[2]. You can find out more about these tests by speaking to your optician.
Your chances of developing glaucoma significantly increase if you are over forty years old. You are also at much higher risk if you have a close relative with glaucoma.  Having diabetes, high blood pressure, steroid treatment or short sightedness are also risk factors[3]. Get your eyes tested today - it’s not worth risking losing your eyesight!
