Presbyopia correcting IOLs are a growing market. There are a multitude of options available to patients and surgeons. The Tecnis Symfony IOL is an extended depth of focus IOL creating just one retinal image along an extended focal point rather than multiple images on the retina. This is reported to significantly reduce dysphotopsia. The IOL has proprietary technology that corrects chromatic aberration negating loss of contrast sensitivity from elongating the focal length.
Retrospective single surgeon patient reported outcome study. A questionnaire was completed on photic phenomena such as glare, halos, starburst, spectacle independence for distance, reading and intermediate vision. Patient evaluation scores for distance, intermediate and near vision. Patient satisfaction with the IOL and a friends and family test of IOL was sought.
Scores were obtained from 24 eyes of 16 Patients. Some patients had not yet completed surgery on the fellow eye either due to the timeline of this study or that they were not yet having visual problems in the fellow eye and wished to defer surgery Eight patients that had Symfony IOLs implanted in both eyes. 7 out of these 8 patients were 100% spectacle independent. The one patient that was not required glasses for intermediate and distance vision, but not near vision.
Eight patients during the study period had only undergone single eye surgery and had the Tecnis Symfony IOL inserted. Two of these reported spectacle independence 100% of the time, 3 patients 25% of the time and the remaining 3 patients required reading glasses 100% of the time
4 of 16 patients reported photic phenomena with glare the most common issue followed by halos and starburst equally.
The Tecnis Symfony IOL is well liked by patients with minimal side effects. Prompt sequential cataract surgery offers better results regarding spectacle independence, 88% in this small sample. Interestingly 63% of patients who underwent single eye surgery reported having to wear reading glasses only 25% of the time or less suggesting they will improve further once the second eye surgery has been performed.
