Trifocal versus extended depth of focus (EDOF) intraocular lenses for cataract extraction

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To compare visual outcomes after implantation of trifocal intraocular lenses (IOLs) to those of extended depth of focus (EDOF) IOLs.

To produce a brief economic commentary, summarising the relevant economic evaluations that compare trifocal IOLs to EDOF IOLs.

This is a protocol.
