Posted: Feb 08 2017

This week, Allon Barsam imparted the latest knowledge about refractive error correction at the UK’s largest optical event. Detailing the most advanced surgical options for treating refractive error in 2017, Allon’s lecture took place at ExCel London on 6th February and was a must-see seminar for anyone working in the field.

Refractive surgery in 2017

Refractive Error Correction, a topic that has been at the forefront of the ophthalmology field, was discussed by renowned ophthalmologist Dr. Allon Barsam at the recent 100% Optical conference. Dr. Barsam, a leading expert in refractive surgery, shared his insights and expertise on various corrective procedures and the advancements in technology that are shaping the future of this field.

Refractive error correction has come a long way since patients were restricted to a choice of glasses or contact lenses. Today’s options for refractive eye surgery utilise the most advanced equipment, including state-of-the-art laser technology, which, combined with a high level of surgical skill, allows for unprecedented precision and an ultra-safe procedure.

Refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related visual decline), affect millions of people worldwide. These conditions can significantly impact one’s quality of life, making the ability to correct them crucial. Dr Barsam’s talk at the 100% Optical conference shed light on the latest techniques and advancements in refractive error correction.

Allon’s talk on refractive surgery included multimedia video and photographic content to illustrate the very latest techniques. It gave the audience an insight into the indications for each type of surgery and a good understanding of the risks, benefits and main characteristics of each option. Attendees came away with knowledge of the latest cutting-edge refractive error correction techniques in 2017.

During his presentation, Dr. Barsam highlighted the importance of personalised treatment plans based on the individual needs of patients. He discussed the different surgical options available, such as LASIK, PRK, and implantable lenses, and explained how each procedure can provide optimal visual outcomes for specific cases.

One of the key areas Dr. Barsam focused on was the advancements in technology that have revolutionised refractive error correction. He spoke about the use of femtosecond lasers in LASIK surgery, which allows for more precise and safer corneal reshaping. Additionally, he discussed the role of wavefront-guided treatments and topography-guided treatments in enhancing visual results and reducing side effects.

Dr. Barsam also highlighted the importance of patient education and shared his insights on how to manage patient expectations. He emphasised the need for thorough pre-operative assessments and discussions to ensure that patients fully understand the potential risks and benefits of refractive surgery.

The audience at the 100% Optical conference had the opportunity to gain valuable insights from Dr. Barsam’s extensive experience and expertise in this field. His talk not only provided an overview of the current state of refractive error correction but also gave a glimpse into future possibilities, such as the use of artificial intelligence and advancements in intraocular lens technology.

In conclusion, Dr Allon Barsam’s presentation on refractive error correction at the 100% Optical conference was a significant contribution to the field of ophthalmology. His expertise and knowledge in this area provided valuable insights for both professionals in the industry and individuals seeking solutions for their refractive errors. With the continuous advancements in technology, it is an exciting time for refractive error correction, and Dr. Barsam’s talk shed light on the promising future of this field.

100% Optical at ExCel London

There were many other exhibits and seminars to attend at 100% Optical, an international event for professionals in the optical industry. The event, which took place at ExCel London over three days from 4-6 February, encompassed eyewear exhibits, the latest in lens technology, a wide range of hi-tech optical equipment and business advice from leaders in the optical field. There were keynote speakers and smaller, discussion-based seminars covering everything from glaucoma, myopia and paediatrics to the future of optometry and ophthalmology.

Optometrists can correct refractive errors with glasses or contact lenses or fix the refractive error with surgery. Glasses. Eyeglasses are the simplest and safest way to correct refractive errors. Your qualified optometrist will prescribe the right eyeglass lenses to give you the clearest possible vision.

Signs you may benefit from refractive error correction

Signs that you may benefit from refractive error correction include difficulty seeing distant objects, blurry vision, double vision, or a decrease in your field of vision. These symptoms can be caused by nearsightedness (myopia), farsightedness (hyperopia), astigmatism, or presbyopia. If you experience any of these symptoms, it is important to seek an eye examination from a qualified optometrist. During this appointment, your optometrist can assess your particular needs and advise on the best course of action for correcting your refractive error.

If you would like to know more about some of the cutting-edge options open to patients with refractive error conditions, our website has overviews of the main procedures.

Laser eye surgery. This bladeless eye surgery encompasses a number of different treatment options, including LASIK and Z-LASIK (using the world’s fastest Zeimer femtosecond laser technology).

Implantable contact lenses. Where laser eye surgery is not suitable, patients who require refractive error correction can now opt for contact lens implants. Phakic IOLs (intraocular lenses) are a permanent but reversible vision correction solution. The procedure is pain-free and quick to perform.

Refractive lens exchange (also known as PreLex or clear lens extraction). This is an option open to patients for whom neither of the above procedures are indicated. It can be used to correct vision in conditions causing refractive error, including myopia, hypermetropia presbyopia.
