Recommendation for presbyopia-correcting intraocular lenses: A Delphi consensus statement by the ESASO study group

Purpose: To establish consensus among experts in lens and refractive surgery to guide general ophthalmologists on issues related to presbyopia-correcting intraocular lenses (IOLs). Design: A modified Delphi method to reach a consensus among experts METHODS: A steering committee formulated 105 relevant items grouped into four sections (preoperative considerations, IOL selection, intraoperative and postoperative considerations). The consensus was defined as ≥ 70% of experts agreeing with the evaluation of a statement. Results: Ten experts participated and completed all rounds of questionnaires (100% response rate). Of 68 items considered in the "preoperative considerations," consensus was achieved in 48 (70.6%). There was a lack of consensus over "IOL selection", the experts only agreed on the importance of the patient's habits for the optical IOL design selection. Of the 14 considerations related to intraoperative issues, the experts reached a consensus on 10 (71.4%). The "postoperative considerations" section reached the highest consensus in 10 (76.9%) items out of 13. Conclusion: Key recommendations for a diffractive multifocal IOL were a potential postoperative visual acuity > 0.5, a keratometry between 40-45D, a pupil larger than 2.8mm under photopic conditions and smaller than 6.0mm under scotopic conditions, a root mean square of higher order corneal aberrations <0.5 μm for 6mm pupil size, while monofocal or non-diffractive IOLs should be considered for patients with coexisting eye disorders. A lack of agreement was found in the issues related to the IOL selection.
