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.
