FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 80601-2-58 has been prepared by subcommittee 62D: Particular medical equipment,
software, and systems, of IEC technical committee 62: Medical equipment, software, and
systems, in co-operation with ISO subcommittee SC 7: Ophthalmic optics and instruments, of
ISO technical committee 172: Optics and photonics. It is an International Standard.
It is published as a double logo standard.

INTRODUCTION
LENS REMOVAL DEVICES and VITRECTOMY DEVICES are used widely in ophthalmology to perform
anterior-segment and posterior-segment surgery on the human eye. Commercial use of these
MEDICAL ELECTRICAL EQUIPMENT devices began in the early 1970s. This document defines
particular requirements for BASIC SAFETY and ESSENTIAL PERFORMANCE of LENS REMOVAL DEVICES
and VITRECTOMY DEVICES, comprising an equipment console, surgical HANDPIECES and
ACCESSORIES connected to this ME EQUIPMENT.
In many parts of the world LENS REMOVAL DEVICES and VITRECTOMY DEVICES are used in
combination by ophthalmic surgeons to perform combined anterior-segment (LENS REMOVAL)
and posterior-segment (vitreoretinal) surgical PROCEDURES to maximize surgical outcomes. For
this reason both LENS REMOVAL DEVICES and VITRECTOMY DEVICES are covered in this document.
As all particular standards in the IEC 60601-1 series are based on IEC 60601-1:2005,
IEC 60601-1:2005/AMD1:2012 and IEC 60601-1:2005/AMD2:2020, the user of this document
is reminded that RISK MANAGEMENT plays an important role in the use of this particular standard.
Compliance with the requirements of this document should be recorded in the RISK MANAGEMENT
FILE to ensure the HAZARDS associated with the product have been considered fully.
Refer to foreword of this document for list of significant technical changes with respect to the
previous edition.
