I have Z-view aberrometer/auto-refractor by Ophthonix. The instrument is in excellent condition, unfortunately the company is out of business. It does however provide very accurate auto refraction numbers and the aberrometer was a great feature and a business builder for patient education, and promoting AR coating, aspheric lenses, etc. We are a small family practice with an emphasis on contact lens fittings and this instrument would have been great for us except it does not perform keratometry. Since we are limited on space, we simply do not have room for it. It is sitting in the box and ready to be shipped out. $2,500. Buyer must pay for shipping.
