Best Lens Implant Alignment By William Goldstein on August 10, 2018

In laser cataract surgery, one of the most crucial steps is the implantation of the intraocular lens or
IOL. The IOL mimics the functions of the natural lens of the eye, thus restoring vision after the
cloudy lens of the eye is removed.
IOL implantation decides the visual acuity of the patient after the surgery. The IOL needs to be
precisely inserted and aligned with the proper axis of the eye in order to ensure that the patient
has no discomfort with vision after the surgery. This process is called the IOL alignment.
IOL alignment is somewhat of a tricky process since  the structures involved are so
delicate and adding to the complexity is the fact that surgeons should not compromise on accuracy.
Typically, IOL alignment involves a number of manual steps like manual data transfer and pre-
and intra-operative marking. These markings are usually made on the cornea of a patient's eye
and are a very laborious and time-consuming process in the surgical workflow.

Zeiss, the German manufacturer of optical products has come up with an excellent technology to
help surgeons skip these manual steps and proceed with the IOL alignment with much better
accuracy. The company designed t8he Zeiss Cataract Suite System for markerless IOL
alignment.

What is the Zeiss Cataract Suite System?

This system includes a combination of precisely designed systems that allow accurate IOL
alignment using computer-assisted biometry. The application of statics and data to biological
measurements is called biometry. The data extracted using this system is efficient, accurate, and
reliable and can be directly used during the laser cataract surgery.

The system consists of 3 main components
1. The Zeiss IOLMaster family- This computer system allows surgeons to take
biometric results for each patient.
2. The Zeiss Callisto Eye-The data extracted from the system is used to create
overlays with the help of the Zeiss Callisto Eye. The system connects every device in the
suite for an efficient and effortless procedure. The system displays a live tracking of
images against the reference images taken using the IOL Master.
3. The Zeiss Opmi Lumera- This is a specially designed surgical microscope. The
details about the axis and placement of the patient’s eye are visible in the eyepiece of this
microscope, thus enabling the surgeon to eliminate the use of manual markers and
directly proceed with the alignment of the IOL.

The Zeiss Cataract Suite system is designed for next-generation biometry and allows surgeons to
handle even the most complicated cases with ease and precision.
