Abstract

Purpose
To compare near-distance reading speeds across different intraocular lens (IOL) types using a Korean reading speed measurement application.
Methods
Patients who underwent bilateral cataract surgery and received trifocal IOL (Panoptix), extended depth of focus (EDoF) IOL (Vivity), or enhanced monofocal IOL (Eyhance) were enrolled. Korean reading speed and reading & speaking speed were measured using a Korean reading speed measurement application. Additionally, satisfaction with visual function in everyday life was assessed using a questionnaire.
Results
No statistically significant differences were observed in postoperative corrected distance visual acuity among the three groups (p = 0.71). The Panoptix group demonstrated significantly higher distance-corrected near visual acuity than the other two groups (p < 0.05). For letter sizes of logMAR 0.5 or larger, the Panoptix group exhibited significantly higher reading and reading & speaking speeds than the other two groups. For letter sizes of logMAR 0.8 or larger, the Vivity group showed significantly higher reading and reading & speaking speeds than the Eyhance group (p < 0.05). The Panoptix group showed significantly greater satisfaction with visual function in work at near distances, including that for activities such as reading a book.
Conclusion
The Panoptix trifocal IOL is expected to provide superior near-vision function and patient satisfaction than other IOL types.
