Mastel Precision has been involved exclusively in the design and production of ophthalmic surgical instrumentation for more than 25 years. We have the most sophisticated fine metal working in the industry, particularly suited to the critical intraocular environment for phaco surgery and also to keratorefractive applications related to astigmatic keratotomy footplate finishes as well as microkeratome servicing. We routinely work at a micron or submicron level as necessary.Diamond scalpels are our primary business. We have complete offerings for all phacoemulsification parameters, Corneal Relaxing Incisions (CRI's) for astigmatism reduction and control, as well as excellent new technology for glaucoma filtration procedures. We are one of the only American companies actually producing diamond scalpels in our nation today.
