Cataract surgery for junior ophthalmologists: are there enough cases?

A virtual cataract surgery course for ophthalmologists-in-training.

Virtual reality (VR) surgery simulation is an emerging teaching tool to train residents in cataract surgery. The widespread adoption of virtual surgery has been limited, however, by high costs and the absence of standardized curricula and evidence demonstrating the impact of VR training on resident surgical outcomes. We outline a resident virtual cataract surgery course--freely accessible onlin...

Are There Enough Injective Sets?

The axiom of choice ensures precisely that, in ZFC, every set is projective: that is, a projective object in the category of sets. In constructive ZF (CZF) the existence of enough projective sets has been discussed as an additional axiom taken from the interpretation of CZF in Martin-Löf’s intuitionistic type theory. On the other hand, every non–empty set is injective in classical ZF, which arg...

Laser Cataract Surgery for Complex Cases?

I avoid the emotional confrontations regarding the general use of laser cataract surgery for routine case management. My sense is that good technology will always win in the end, despite the difficulty associated with the business model in this instance. With respect to the literature, the following comes from a recent and extensive review of the literature on the subject: “Randomized controlle...
