Patients with higher levels of postoperative astigmatism reported a greater improvement in quality of life and a greater willingness to have the surgical procedure again if they received an extended depth of focus intraocular lens (EDOF IOL), compared to patients receiving a low-add multifocal lens.
A study conducted by David Teenan, FRCOphth, and Stephen Hannan, OD, Optical Express, Glasgow, UK, compared the effect of postoperative residual astigmatism on clinical and patient-reported outcomes in patients implanted with an EDOF lens (Symfony, Johnson & Johnson Vision), and a segmental-add, multifocal intraocular lens (MF20, Oculentis). The preoperative and demographic characteristics of the two groups were similar and there were no statistically significant differences (See Figure 1).
The researchers found that at 3 months, the lenses had similar postoperative clinical and patient-reported performance. However, in the group of patients who had higher levels of postoperative residual astigmatism (>1 D), the EDOF group reported greater satisfaction with their quality of life and willingness to undergo the procedure again than those receiving the multifocal IOL.
