Purpose
To evaluate light distortion and visual symptoms after binocular implantation of bi-aspheric diffractive trifocal intraocular lens (IOL) 6 months after implantation.
Setting
Clinica Baviera Sevilla, Spain
Methods
30 eyes from 15 patients who underwent bilateral implantation with the AsqelioTM Trifocal IOL TFLIO130C (AST Products Inc, Billerica, Massachusetts, U.S.A.) were examined 6 months after surgery. Light distortion was determined using the Starlight LDA Analyzer (BinaryTarget SA, Portugal) and patient-reported visual symptoms were recorded. Refractive error and visual performance were also measured
Results
Light distortion index was 20,1±11% with good visual outcomes and patient satisfaction. All patients reported being fairly satisfied to very satisfied with their vision at present, with 80% reporting no difficulty with vision in daily life. Visual symptoms reported by patients were mostly haloes (80%), but only reported mild to none with regards to severity and bothersome.
Conclusions
This prospective non-randomized study shows that, although light distortion occurs with diffractive trifocal IOLs, it was lower than reported literature with trifocal IOLs, and visual symptoms associated did not reach clinical relevance.
