At present, only one design is available for trifocal intraocular lens (IOL); unfortunately, this particular design is not suitable for implantation in the sulcus with optic capture when posterior capsule rupture (PCR) occurs. Although three-piece bifocal IOLs can be implanted in the sulcus, this form of IOL can be vulnerable to tilt and decentration, thus causing aberration and photopic phenomena, such as halos and glares. However, visual axis centered optic capture using femtosecond laser-assisted cataract surgery (FLACS) is able to manage such complex operations. In the present study, we implanted a three-piece +4.0 D bifocal IOL into the sulcus of a patient who experienced PCR using optic capture and FLACS following the straightforward implantation of a one-piece trifocal IOL in the other eye. Defocus curves showed that the weakness of the trifocal IOL (nearest distances) was compensated for by the strength of the +4.0 D bifocal IOL, whereas the weakness of the +4.0 D bifocal IOL (middle distance) was compensated for by the strength of the trifocal IOL. Therefore, this combination provided the patient with a wider range of depth of focus. The contrast sensitivity in both eyes was within the normal range. Photopic phenomena were comparable with the bilateral implantation of the trifocal IOL. Anterior segment optical coherence tomography showed that tilt and decentration in the trifocal IOL implanted in the bag was significantly higher than the +4.0 D bifocal IOL implanted in the visual axis centered optic capture. This case showed that the intraindividual implantation of a single-piece trifocal IOL in the bag and a three-piece +4.0 D bifocal IOL in the sulcus, using a combination of optic capture and FLACS, is promising particularly in cases of PCR and can provide a wider range of vision without losing visual quality.
