4Carl Zeiss Meditec AG, IOLMaster 700 SW 1.80 & Total Keratometry (TK)
Total Keratometry (TK)Replacing assumptions with measurements
• Total Keratometry (TK®) is a new measurement that combines telecentric keratometry and SWEPT Source OCT technology for the assessment of anterior and posterior corneal curvature.
• The purpose of TK is to replace standard keratometry, aiming to help to reduce outliers and improve refractive outcomes of IOL calculation in cataract surgery.
• TK is ULIB-compatible, therefore existing standard formulas and IOL constants may be applied.ed.

5Carl Zeiss Meditec AG, IOLMaster 700 SW 1.80 & Total Keratometry (TK)
Total Keratometry (TK)Replacing assumptions with measurements
With Total Keratometry (TK)
• The posterior corneal surface can now be directly measured with SS-OCT and used in formulas onboard the ZEISS IOLMaster without changing your clinical workflow.
• Thus, it is no longer necessary to use assumptions or nomograms of the posterior cornea.
This improves the results of toric IOL power calculations: 14% more patients within +/– 0.5D cylinder (Haigis-T*).

What Do Doctors Say?
Graham Barrett, MD, Perth, Australia
“I am very impressed with the results I have obtained with the IOLMaster 700.”
“TK has the potential to reduce refractive surprises to a minimum.”
Han Bor Fam, MD, Singapore
“For toric and non-toric, the TK value improves the overall outcome.”
“It tightens consistency, it reduces the outliers and enhances the overall outcome.”

24Carl Zeiss Meditec AG, IOLMaster 700 SW 1.80 & Total Keratometry (TK)
• The IOLMaster is the only optical biometer on the market that uses a smart optical configuration that allows telecentric and thus distance-independent keratometry.
o ‘Motion independent’ keratometryo Independent of focus (easy & comfortable to use)o Direct radius measurement (constant spot distance)o Visual assessment of dots for tear film integrity
• Robust, precise and repeatable keratometry measurements
• NOW, the IOLM combines unique telecentric keratometry measurement of the anterior corneal surface with measurement of the posterior corneal surface in order to calculate Total Keratometry (TK).

29Carl Zeiss Meditec AG, IOLMaster 700 SW 1.80 & Total Keratometry (TK)
Chang-Waring Chord (Angle Kappa)Evaluate pre-op for Multi-focal IOL implantation – Screen patients suitability
• Jack Holladay, MD. – „Pay attention to the Angla Kappa!“
• The dimension between the visual axis and the pupil is called the angla kappa (or chord mu / CWC).
• The proper place to center a diffractive, premium aspheric, or toric IOL is halfway between the visual axis and the center of the pupil.
• If that value is greater than 0.6mm, patients with diffractive lenses will have halos and glare.

Change of LVC statusNo need to re-measure the patient!
• Ability to change LVC status post-acquisiton.
• This is not possible with LVC status: RK.
o Only Barrett Suite (ie. Barrett True-K) will calculate for post-RK patients (with standard Ks).
35Carl Zeiss Meditec AG, IOLMaster 700 SW 1.80 & Total Keratometry (TK)
Total Keratometry & Post-LVC FormulasExpand IOL calculation for your post-LVC patients
• TK measurement values can be used to calculate post myopic LASIK and PRK with Haigis and Holladay II formulas (ie. formulas that do not consider Ks for the ELP prediction).
• TK measurement values cannot be used with LVC formulas such as Haigis-L and Barrett True-K.
• IOLMaster 700 will block any calculations that are not yet available.
o EG. Barrett TK calculation is not possible using LVC ‘RK’.
o EG. Barrett TK Toric calculation is not possible using LVC ‘LASIK/LASEK/PRK’.

ZEISS IOLMaster 700 Formulas for IOL Power Calculation
Quick Guide
Quick Guide
This guide is intended to provide information on the IOL power calculation formulas installed on the IOLMaster® 700 from
ZEISS with software version 1.8.
Users should confer with their respective IOL representative to ensure the dataset represents the most recent
updates for the manufacturer’s IOL and to modify the definitions if needed.
NON-TORIC FORMULAS
3rd Generation Formulas
The Holladay I, Hoffer Q and the SRK/T emerged as the third-generation formulas. These formulas were a merger of the
linear regression methods with theoretical eye models. These formulas make assumptions about the architecture of the
anterior chamber based on K value. EG. Flat K assumes shallow anterior chamber depth (ACD), and therefore underestimates
IOL power. The reliance on theoretical assumptions is led to the differences between the three formulas.
Holladay 1
The Holladay 1 formula uses the postoperative stabilized refraction value, the dioptric power of the implanted IOL and the
preoperative corneal and axial length (AL) measurements to calculate a personalized surgeon factor. Thus, the surgeon
factor is defined as the distance from the postoperative anterior iris plane to the effective optical plane of the IOL. As with
other constants the surgeon factor (SF) is not actually a measurement, but a number representing a particular surgeon’s
previous experience.
Hoffer Q
The Hoffer Q formula relies on a personalized ACD, AL and corneal curvature. The personalized ACD (pACD) is developed
from any given series of a particular IOL style. It includes:
• A factor that increases the ACD with increasing AL
• A factor that increases the ACD with increasing corneal curvature
• A factor that moderates the change in ACD for extremely long and short eyes
• A constant added to the ACD
SRK/T
The SRK/T formula is a theoretical (T) approach to IOL power calculation under the SRK umbrella of empirical formulas using
existing A-constants and optimization methods. Empirical optimization methods of the SRK/T model primarily consist of:
• Postoperative ACD prediction
• A retina thickness correction factor
• Corneal refractive index
4TH GENERATION FORMULAS
Haigis Formula
The Haigis formula recommends an IOL power based on a three-variable (a0, a1 and a2) function. The a1 constant is tied to the
measured ACD, while the a2 constant is tied to the measured AL.
• Haigis (a0 optimized only): normal eyes
• Haigis (a0, a1, a2 optimized): short to long eyes
This allows all three constants to be optimized for a wide range of ALs and ACDs using double-regression analysis. The Haigis
formula does not depend on assumptions for the ACD, and acquires real measurement of it.
Holladay 2 Formula
The Holladay 2 formula is conceptually based on the Holladay 1 formula, however, it uses seven parameters for predicting the
surgeon factor. These are the AL, corneal power, ACD, lens thickness, age, white-to-white corneal diameter and preoperative
refraction data. The formula requires lens thickness if AL ≤ 22mm. This allows for optimization over a larger range of ALs. How the
formula works in detail has not been published by Jack Holladay.
NEW GENERATION FORMULA
Barrett Universal II
The Barrett Universal II formula uses a theoretical model eye in which the ACD is related to the AL and keratometry. A relationship
between the A-constant and a “lens factor“ is also used to determine the ACD. The important difference between the Barrett
formula and other formulas is that the location of the principle plane of refraction of the IOL is retained as a relevant variable in the
formula.
The lens factor (LF) used in all Barrett formulas is the equivalent to other constants used in standard IOL power calculation formulas.
It is comparable, though not identical, the SF or the Haigis a0, a1 and a2 constants. Like most of those constants, the LF can be
derived from the SRK/T formula’s constant, using a formula established and verified by Professor Barrett.
Unlike the LF or other IOL constants, the design factor (DF) is not subject to optimization but is characterized by the design of one
specific IOL. Design factors are therefore fixed values. The DF can only be defined by the respective IOL’s manufacturer with detailed
knowledge of the respective IOL’s design.
TORIC FORMULAS
Haigis-T Formula
The Haigis-T formula is an extension of the well-established Haigis formula, for IOL power calculation of toric IOLs. If patient has
also had refractive surgery, a combination of Haigis-T and Haigis-L will be applied (ie. Haigis-TL formula).
Barrett Toric Formula
The Barrett Toric formula is an extension of the Barrett Universal II formula, for IOL power calculation of toric IOLs. It theoretically
takes into account the posterior surface of the cornea (no actual measurement, based on nomogram) and also makes adjustments
for WTR and ATR astigmatism. It has the option to utilize up to 5 variables consisting of AL, Ks, ACD (optional), LT (optional) and
WTW (optional).
POST-LVC FORMULAS
Haigis-L Formula
The Haigis-L formula is an extension of the Haigis formula, for IOL power calculation of post-LVC eyes (LASIK/PRK/LASEK) – myopic/
hyperopic. No history is required. It accounts for the surgical changes to the cornea by employing a correction factor for the
measured keratometry.
• Myopia: a correction factor for the ACD change
• Hyperopia: a correction factor for measured keratometry only, since no ablation
Haigis-TL Formula
The Haigis-TL formula is a combination of Haigis-T and Haigis-L formulas, for IOL power calculation of toric IOLs for post-LVC eyes
(LASIK/PRK/LASEK).
Barrett True-K Formula
The Barrett True-K formula is an extension of the Barrett Universal II formula, for IOL power calculation of post-LVC eyes (LASIK/
PRK/LASEK – myopic/hyperopic and RK). No history required. The formula calculates a modified keratometry value for post-refractive
patients. It requires pre- and post-refractive surgery refractions for maximum accuracy.
BARRETT TK FORMULAS
Barrett TK Universal 2 and Barrett TK Toric
To further improve his classic formulas, Professor Graham Barrett has developed two new ones for use with Total Keratometry (TK):
the Barrett TK Universal II for non-toric IOLs, and the Barrett TK Toric for toric IOLs. They use posterior corneal surface
measurements instead of the eye model used by the previous Barrett formulas.
NOTE: For all IOL power calculations of post-LVC patients, always indicate LVC type in patient manager screen or
IOL calculation screen, and the LVC mode (myopic/hyperopic) in IOL calculation screen.

Introduction to this Quick Guide
This guide provides information and instructions on manual entry of toric IOLs in the ‘Lens Manager’
(found under “Settings”) of the IOLMaster® 700 from ZEISS with software version 1.80.
As different IOL manufacturers offer toric IOLs in different and sometimes inconsistent toric power
steps, the ZEISS IOLMaster 700 allows users to manually add IOLs, define the delivery range and
specifically define the spherical equivalent (SE) range, SE increment, cylinder (CYL) format, CYL range
and CYL increment.
The process of entering new toric IOLs may take some time, during which the ZEISS IOLMaster cannot
be used. Depending on how many IOLs and users are to be entered and the complexity of the IOL
definitions the required time may vary between a few minutes and more than an hour.
This guide explains IOL configurations in the lens manager for toric IOLs with inconsistent step
sizes (e.g. ZEISS IOL) and consistent step sizes (e.g. Alcon). It also provides respective examples.
For toric IOLs not listed in this guide, please use the examples below as templates and refer
to the respective IOL manufacturer or your ZEISS representative for further information.
Availability of IOLs and their respective power ranges and step sizes can vary regionally.
All IOL information in this document is provided without a guarantee of correctness; the
user is responsible for the correctness of all manual inputs.
All powers must be entered according to IOL labelling standards, i.e. powers are meant
to be entered on lens-plane, NOT on corneal plane, as provided by the respective IOL
manufacturer.
Users can download pre-set IOL definitions for all IOLs listed on the ULIB website via
(https://cataract-community.zeiss.com/tools/lensconstantsdownloads). The same set of pre-set
definitions is shipped with all software updates and with all new ZEISS IOLMasters. It can also be
requested from the ZEISS representative. This set of definitions can then be imported in whole or parts
via the “lens manager” import settings. For lenses included on this dataset manual configuration is no
longer required, unless users want to change IOL constants or ranges. If choosing to download and
utilize these IOL definitions, users are still encouraged to contact their respective IOL representative
to ensure the dataset represents the most recent updates for the manufacturer’s IOL and to modify
the definitions if needed.
If you want to use your own IOL constants with IOLs that are available on ULIB, please consider
importing the IOL automatically via the download and then change the IOL constants. This is likely
to save you time in the process.
