2. Introduction

Thank you for purchasing your Keeler Cryomatic MKII.

We have taken the greatest care in the design, development and
manufacture of this product to ensure that you get many years of
trouble free service. However, it is important that you read the
descriptions, installation and operating instructions carefully prior
to installing or using your new Cryomatic MKII.

About this Manual

This handbook forms the Instructions for Use for the Keeler
Cryomatic MKII, a clinical instrument for cryogenic ophthalmic
surgery.

It contains complete, step-by-step instructions for the
Cryomatic MKII and is intended for use by trained medical
personnel. This manual does not contain clinical instructions or
any recommendations for medical applications. The use of the
Cryomatic MKII in any surgical procedure must always be at the
discretion of a licensed medical practitioner.

Intended use

The Keeler Cryomatic MKII System and probes are for use in
ophthalmic surgery such as cryopexy for retinal detachment, cyclo
destructive procedures in refractory glaucoma, extraction of
fragments within the vitreous cavity, cataract extraction, cryo
destruction of lash follicles for trichiasis and treatment of
retinopathy of prematurity (ROP).

Once the Cryo probe has been correctly positioned the freeze
control is activated and an ice ball is formed around the tip of the
Cryo probe and the adjacent area.

Please read and follow these instructions carefully.
