two measurements either in the axis or astigmatism amplitude, he may have to assess whether this patient may have dry eye. It is also very important to measure the posterior corneal surface as it is known that the anterior and posterior surfaces behave differently. “We know that if we use ssOCT, which measures the posterior cornea, you get even better results than using, for example, Scheimpflug tomography,” said Dr. Findl. How does one deal with deviations between measurements, then? Currently, there are no evidence-based guidelines available to deal with deviations in measurements. Thus, Dr. Findl approaches this issue by planning his patients’ treatment in EQ Workplace. In this program, data is taken from the IOLMaster 700 and guides the surgeon through the entire planning phase. Keratometry values can be selected to the surgeon’s preference, and different IOL types can be selected by the surgeon based on the patient’s needs. A key feature Dr. Findl pointed out is that EQ Workplace can export data for both the left and right eye in an email which can then be directly sent to the IOL manufacturer for IOL ordering. “This is a neat feature because you don’t have to do any transfer of data, which has the trouble of making some errors or mistakes,” said Dr. Findl. Until now, Dr. Findl used to do preoperative marking. However, with quite some variability among different marking devices, Dr. Findl now prefers digital marking using images taken with the IOLMaster 700. These images provide an overlay of preoperative and intraoperative images, which then gives the possibility of doing a proper alignment of the toric IOL. Dr. Findl is also able to use the EQ Mobile application on his smartphone to transfer patient data directly into the computer connected to the microscope in the case that his operating room (at a hospital) is located away from his clinic. “The EQ Mobile is my bridge between the data I have in my private practice and the computer that is connected to the microscope,” said Dr. Findl. With EQ Workplace, Dr. Findl is able to increase the efficiency of his workflow in more ways than one. An automatic transfer of data steers clear of manual entry for IOL power calculations, thus avoiding potential errors. IOLs can be selected when patient informed consent is provided, and IOLs can be ordered directly from the workplace as well. “When the patient leaves my room, everything is planned and everything is done. That is, for me, the biggest asset of using the EQ Workplace,” said Dr. Findl. With more automation, surgeons can prepare, perform, and follow up on cataract surgeries with greater efficiency.

Cataract and Refractive Surgery Fast & Fabulous - The VISUMAX 800 & the QUATERA 700 Experience On Sunday June 12, 2022, ophthalmologists gathered at a video symposium hosted by ZEISS to discuss experiences with the VISUMAX 800 and QUATERA 700 systems. John S. M. Chang, MD, Hong Kong, began the discussion talking about whether speed matters during surgery and whether a faster speed in surgery means more danger to the patient. In Dr. Chang’s experience with a smaller machine, the VISUMAX 800 provides integration with the Corneal Refractive Workflow, allowing for more efficient processes. Some specific advantages of the VISUMAX 800 is that this machine provides better centration, faster treatment at 2 MHz, and better ergonomics. Additionally, it can also provide better astigmatism treatment in that it has the ability to match treatment to cornea marking after suction. In a study that Dr. Chang presented, he found that the VISUMAX 800 did result in better centration with no decentration and the cyclotorsion adjustment feature provided better astigmatism results. Furthermore, a faster surgery meant zero suction loss and thus less stress and more convenience for the patient. Sri Ganesh, MBBS, MS, DNB, DSC, FRCS, India discussed his experience with the QUATERA 700. The QUATERA 700 consists of a QUATTRO® pump which is a synchronized fluid-exchange system with two infusion chambers, variably controlling the infusion rate. Two aspiration chambers control the aspiration and vacuum levels. With the four syringe-like chambers working together, there is a synchronization and reciprocal exchange of fluid. In the cases Dr. Ganesh presented, he was able to show that the new quattro pump of the QUATERA 700 enhances both safety and efficiency for the patient without any compromise due to its complete chamber stability even at the highest flow and vacuum rates. The surgical cockpit also integrates the QUATERA with the IOL Master 700, Callisto eyes, and Surgical Microscope seamlessly, making the workflow very efficient. Refractive and Cataract Workflow
