Innovation in Eye Care

Mr Barsam is a key opinion leader for the ophthalmic
industry and is often asked to work with companies
to develop the newest techniques.

Allon Barsam is a surgical innovator and is therefore heavily involved in the development of new techniques and equipment. Many of these technologies are patented or have patents pending.

His innovation in eye care allows him to advance his field but also ensures that he continually evolves his surgical techniques to provide his patients with access to the most technologically advanced treatment options available – something many people expect in London laser eye surgery clinics.

Allon Barsam’s Highlights Include…

  • The first British Ophthalmologist in the world to use laser vision correction technology for cataract surgery with the use of intraoperative aberrometry to refine visual outcomes.
  • A capsular segment to facilitate safe lens removal in complex cataract surgery.
  • The first British Ophthalmologist and one of the first ten surgeons in the world to carry out laser cataract surgery.
  • An intraocular telescope to complement cataract surgery in patients who also have age related macular degeneration.
  • The first to carry out human treatments of microwave keratoplasty, a new treatment modality for keratoconus.

Did You Know?

Allon Barsam was recently selected by Rayner to be the first eye surgeon in the world to use their newest micro incision lens injector for cataract surgery.

This achievement was documented by a Rayner Intraocular Lenses Limited blog-post:

Rayner Intraocular Lenses Limited announced the launch of the RaySert PLUS inject. RaySert PLUS is designed for safe and effective implantations through a 2.2mm wound assisted mini incision, reducing the level of surgical induced astigmastism, according to a company news release. Approved for the delivery of the C-flex Aspheric and Superflex Aspheric range of Rayner IOLs, it is supplied in a system pack format with the IOL.

The first implant was safely completed by Allon Barsa, at the Luton and Dunstable University Hospital, UCL Partners in the United Kingdom on the March 14, 2014. “Much like the earlier 2.7mm Rayner Injectos and the later 2.4mm Raysert Injectors, the new 2.2mm Raysert PLUS has a very easy and simple loading mechanism. The one-handed injector frees up the non-dominant hand for counter fixation to facilitate a controlled and gentle wound assited deliver of the lens into the capsular bag” Dr. Barsam, MB, BS, MA, FRCOphth, Consutant Opthalmic Surgeon Specialist in Cornea, Cataract and Laser Eye Surgery, said in the news release.

Dr. Barsam applauded Rayner’s move to smaller incision cataract surgery: “For those familiar with rayner’s 2.7 mm and 2.4mm injectors, noextra adaptation of surgical technique is required. This represents an exciting new development from Rayner in the move to smaller incisions during cataract surgery” added Dr. Barsam.
