Register now for the webinar trilogy: Treating dense cataracts – when routine becomes a challenge

Dr. Don Pek, Dr. Ruth Lapid-Gortzak, Dr. Nino Hirnschall, Dr. Sartaj Grewal & Dr. Franco Spedale

Removing hard cataracts can be difficult even for the most experienced cataract surgeons. Patients are typically older, with low visual acuity and coexisting ocular pathologies. Thus, it is essential to understand the patient's underlying conditions and to prepare for possible challenges during the surgical procedure.

On the one hand, pre-operative cataract evaluation is an occurring challenge since a dense cataract is, by its very nature, difficult to penetrate. On the other hand, lens fragmentation of a dense cataract requires a lot more phaco energy to emulsify the hard nucleus. More energy increases the risk of damage to corneal endothelial cells, which, in turn, can cause post-operative complications.

Dr. Don Pek will guide you through the trilogy on the topics of:
Webinar 1: Dense cataract – what is it about? with Dr. Ruth Lapid-Gortzak
Webinar 2: Be prepared for your dense cataract cases with Dr. Nino Hirnschall
Webinar 3: Bring it all together & split it with ease with Dr. Franco Spedale and Dr. Sartaj Grewal
