At John Weiss & Son Ltd we share a passion for micro surgical instruments. With over 225 years' experience in manufacturing we are able to combine our appreciation of the surgeon's art with an understanding of manufacturing demands to create new, original instruments and improve on classic designs.

From the original London showroom and workshops to its present location in Milton Keynes, the company has strived to adapt and evolve to the ever changing needs and demands of the modern surgeon. John Weiss & Son Ltd continues to be the leading brand domestically whilst successfully exporting to over 40 countries worldwide. Now with the international backing of the Haag-Streit Group of companies, the product range has expanded to over 2500 products encompassing all subspecialties of Ophthalmic Surgery; cataract, corneal, oculoplastic, glaucoma and vitreoretinal, as well as Middle Ear Surgery.

Sir Everard Home once described John Weiss as being "one of the few contemporary instrument makers steady enough to stick to the task of furthering the design of new instruments, rather than merely cashing in on the expanding trade of established ones." This design philosophy remains as strong today as it did then, continuing to drive John Weiss & Son Ltd to pursue excellence in today's competitive, and increasingly demanding marketplace.
