SULCUS-TO-SULCUS AND ICL SIZING.
ICL lenses have gained in popularity in recent years. Along with these premium lens, patients and surgeons alike demand the best results with minimal complications. Proper selection of ICL size is imperative during pre-operative assessment – too large of a lens leads to excessive vault and elevated IOP, too small of a lens leads to displacement, and both cases require explantation, unnecessary risks, and unhappy patients.
Many leading ICL surgeons achieve success by measuring the distance from sulcus-to-sulcus and applying well-established nomograms to determine proper lens sizing. How important is the use of sulcus-to-sulcus measurements in properly sizing ICL lenses? In one study, it was determined that using the sulcus-to-suclus nomogram provided by the VuMAX™ led to no cases of unacceptable ICL vault compared with reported levels of 15% to 20% based on white-to-white measurements. Additionally, the use of white-to-white measures would lead to the use of a different sized lens than the use of sulcus-to-sulcus measurements in 34% to 65% of cases, potentially requiring explantation in a significant number of patients. (Rivera, R. et al “Sizing Nomogram for ICL Vault Determination Using Sulcus-to-Sulcus Measurements Obtained with High Frequency Ultrasound”).

Sonomed Escalon recognizes the significant contributions of Robert Rivera, MD (1956 – 2015) and continues to make available the results of his extensive research and experience as a means of advancing the field of ophthalmology. His presence will be missed, but his legacy will live on.
UBM AND GLAUCOMA
Dr. Michel Puech explains the importance of using UBM in assessing the angle, in part, to determine causes of closed angles
IMPORTANCE OF UBM IN GLAUCOMA MANAGEMENT
UBM imaging is an essential diagnostic technology for the diagnosis and management of angle-closure glaucoma. Through unmatched resolution of the different structures at the angle, Sonomed Escalon UBMs provide excellent diagnostic tools for glaucoma-related concerns that cannot be evaluated by other examination methods, helping in identifying the reasons for elevated intraocular pressure and assess treatment effectiveness:
Relative Pupillary Block
Plateau Iris Syndrome
Pupil Movement
Other Secondary Causes
