Top Case: ZEISS IOLMaster 700 in Posterior Subcapsular Cataract

by Dr. Mario de La Torre
likes 0 likes

The ZEISS IOLMaster 700, using SWEPT source biometry, evaluated a dense subcapsular posterior cataract in a 21-year-old male. Abnormal lens fibers attached to the nucleus and underlying posterior capsule were also identified. These were removed during surgery, reducing the risk of spontaneous posterior capsule rupture.

The First Experiences with the IOLMaster 700 by Dr. Mario de La Torre

Dr. Mario de La Torre presented his first experiences with the IOLMaster 700 at the "Meet the Experts" event during the ESCRS 2015 in Barcelona. In this presentation, he elaborated on the subject of dense cataracts and how the IOLMaster 700 achieved superior penetration. In his opinion, the IOLMaster 700 offers numerous advantages compared to other optical devices, e.g. much better penetration, lower rate of measurement failure and a more efficient workflow. In addition, this device opens interesting doors to research and new trends in IOL calculation.

Top Case: IOLMaster 700 in Cases of Extreme Cataract

Prof. Mario de La Torre from the Universidad Nacional Mayor de San Marcos in Lima, Peru, reports about two cases of extreme cataract. While conducting axial length measurements was not possible with any of his previous optical biometry devices, the IOLMaster 700 was able to do this because of its advanced imaging options. According to the case results, the possibility of detecting unusual eye geometries and poor fixation patterns will eventually lead to improved refractive outcomes.

Occult macular pathology in cataract patients is one of the issues of most concern for ophthalmologists when considering premium IOLs. Dr. Sabon Srivannaboon of Mahidol University, Faculty of Medicine, discusses a case, where the fixation check scan of the IOLMaster 700 revealed critical information that led to an additional retina OCT examination – with consequences for the surgery and IOL selection.

Top Case: B-scan Shows Structural Changes of Eye Throughout Lifetime

by Dr. Tobias Buehren

Cataract surgeons are well acquainted with the idea that the natural lens of the eye is subject to structural changes throughout the human lifetime. Knowing about this is one thing, watching it happen is a different matter altogether. Dr. Tobias Buehren from ZEISS presents a case that offers a first glimpse into this process using swept-source biometry.

Taking biometric readings of patients with corneal inlays are not yet routine in daily practice. Given the high prevalence of presbyopia and the high level of interest in spectacle independence this might change. Here a case is presented using swept-source biometry.

Comparing Two Optical Biometric Devices Head-to-head

Today's cataract surgeons have adopted non-contact optical biometry as the standard in performing IOL calculations. But which specific device will best meet their needs? Amin Ashrafzadeh ("Dr. Ash") wanted to answer this question for himself and undertook the task of performing a prospective comparison of two non-contact biometers - the IOLMaster 500 and the Lenstar LS 900.
