Cataract Surgery – Serving patients seeking cataract surgery in London and throughout Great Britain; in the Middle East, serving patients seeking cataract surgery in Qatar, Dubai, Riyadh, Abu Dhabi, Bahrain and Jetta

Allon Barsam, MB, BS, MA, FRCOphth, is a consultant ophthalmic surgeon practicing in the Harley Street enclave of central London, Hertfordshire and Bedfordshire. He is one of very few eye surgeons in the United Kingdom who has completed prestigious training fellowships in the United States and the United Kingdom in cornea, cataract and laser vision correction surgery. Mr. Barsam was the first British ophthalmologist worldwide to perform high-volume femtosecond laser cataract surgery, and is currently one of very few consultant ophthalmic surgeons in the United Kingdom to provide patients with laser cataract surgery. He is well-known for his advancements in the field of ophthalmology, and his work has been showcased in various media outlets, including national radio, the Discovery Channel and BBC News.


Mr. Barsam is often involved in the development of new ophthalmology techniques and technology, ensuring that he is a leader in the industry. Staying abreast of technological advancements in the field allows Mr. Barsam to provide patients with fantastic vision correction results, whether he is performing cataract surgery or laser eye surgery, including LASIK. He not only treats patients in London but across Great Britain and throughout the Middle East.




To start laser cataract removal surgery, Mr. Barsam uses a femtosecond laser to make a tiny incision in the capsule that holds the eye’s lens. Next, Mr. Barsam uses ultrasound energy to break up the cataractous, or cloudy, lens gently prior to suctioning out the cloudy lens pieces from the eye. Finally, he replaces the cataractous lens with an intraocular lens implant, also known as an IOL. The premier cataract surgeon offers a wide assortment of IOLs to improve patients’ distance, near and intermediate vision. By selecting a premium IOL, Mr. Barsam can also correct presbyopia and astigmatism if needed.

In addition to treating astigmatism with toric IOLs, Mr. Barsam can utilize multifocal or accommodating IOLs to correct distance and near vision simultaneously. Mr. Barsam is also a top provider of laser eye surgery, including all-laser, bladeless, wavefront-guided LASIK surgery, as well as a leading provider of other refractive surgeries.

To schedule a personal consultation with Mr. Barsam and learn more about your cataract surgery and vision correction treatment options, please contact his office by calling 44 (0) 7716 098 922.
