Dr Florian Kretz discusses the advantages of trifocal intraocular lenses (IOLs), and how mixing them with extended depth of field (EDOF) IOLs can create a variety of options for patients with differing requirements. EDOF IOLs are available in different optics; some correct for astigmatisms, dry eye, and other irregularities, and others offer refractive corrections. Dr Kretz explains how these IOLs can be combined in a number of different variations to offer the patient various benefits. Problems with near vision can be overcome by combining a trifocal IOL in one eye and an EDOF IOL in the other. Dr Kretz highlights the importance of extensive patient counselling in order to determine the exact needs of the patients based on the distances they work and read at, and any hobbies which may need to be taken into consideration. This extensive counselling and the variety of IOLs available allows a great degree of individualised care.
