Feedback: Essential CL practice interactive 2

In the discussion of the first interactive exercise, which looked at the initial choice of correction of presbyopia, I expressed my surprise at the clear split in responses between those favouring multifocal lenses and those preferring monovision. A healthy topic for discussion should always reveal some divergence of views, and it would appear that this second exercise has similarly shown a split of opinion among respondents.

I think it is safe to suggest that the debate about whether to choose a conventional hydrogel or a silicone hydrogel as first choice for daily disposable contact lens wear is still alive and well. For example, it was only last year during an online education event (see Optician 07.05.21), that a healthy discussion between Professors Nathan Efron and Phil Morgan touched upon the subject, with Efron tending to emphasise the benefits of a silicone material while Morgan defended the many benefits of a hydrogel approach. The debate has also been covered in this publication, with reviews of the topic reflecting a wide literature base to support either material choice.^1,2
