Clinical outcome comparison: bilateral trifocal vs. mix– match extended depth of focus and trifocal intraocular lenses
MetadataShow full item record
Purpose To analyze the visual outcomes, contrast sensitivity (CS), and patient satisfaction differences between the bilateral implantation of a trifocal intraocular lens (IOL) and the mix–match implantation of an extended-depth-of-focus (EDOF) IOL and a diffractive trifocal IOL. Methods A total of 20 patients who underwent bilateral implantation of AT LISA tri 839MP (Group 1) and 20 patients who had a mix–match implantation of AT LARA 829MP in the dominant eye and AT LISA tri 839MP in the nondominant eye (Group 2) were evaluated. Uncorrected distance (4 m), intermediate (60 cm and 80 cm), and near (40 cm) visual acuity, as well as CS, defocus curve, and responses to the patient questionnaires, were evaluated. Results Eighty eyes of 40 patients were included. Uncorrected distance and near visual outcomes were similar between the groups (p [0.05). Group 2 showed significantly better intermediate visual outcomes at 60 cm and 80 cm than Group 1 (p \0.05). Group 2 showed significantly better CS outcomes (photopic and mesopic) than Group 1 (p \0.05). There was no significant difference between the groups regarding defocus curves from ? 0.00 D to - 2.00 D, but a significant difference was shown from - 2.00 D to - 4.00 D. Patients’ satisfaction was significantly higher in Group 2 for driving at night (p\0.05). Conclusions Both groups showed an effective visual performance. Group 2 exhibited better photopic and mesopic CS. The combination of EDOF and trifocal IOL seems to be a good option with a comfortable vision at all distances and less adverse visual phenomena.
