Allon Barsam has had me as a patient twice now, first time for removing cataracts plus correcting my vision (excellent result!) and now to carry out a YAG procedure to treat my cloudy vision. Allon explains all steps in detail and I never felt there was anything to worry about.

I had Smartsight surgery with Allon Barsam about 2 months ago. The whole process from initial consultation, to surgery, to follow up appointments has been fantastic, and I would highly recommend OCL to anyone considering vision correction. You really get that premium, personalised feel here. Everyone I interacted with was kind, helpful and reassuring. I'm delighted with my new vision and the days of having to think about contacts and glasses feel like a distant memory. A heartfelt thank you to the whole OCL Vision team!

The initial consultation, the surgery and followup appointments at OCL Vision were very professional and friendly. I was put at ease before and after the surgery. It could not have been smoother. Answers to questions on emails we dealt quickly and comprehensively. Mr Allon Barsam, my consultant, came highly recommended and I totally agree with all the positive feedback he receives. He was informative whilst not over complicating the information and was more than happy to answer all my questions pre and post surgery. I am very happy to no longer need contact lenses and glasses. All in all a very positive experience. I would highly recommend OCL Vision.
