Comparison of clinical outcomes of trifocal intraocular lens (AT LISA, Eyecryl SERT trifocal) versus extended depth of focus intraocular lens (Eyhance, Eyecryl SERT EDOF)

Abstract

Purpose:

To compare four different types of intra ocular lenses (IOLs), namely, AT LISA, Eyecryl SERT trifocal, Eyhance, Eyecryl SERT extended depth of focus (EDOF) with respect to their clinical outcomes.

Methods:

This is a retrospective comparative study in which patients who underwent surgery and one of the four types of IOL were implanted. Postoperative evaluation was recorded at one month, postoperatively. The monocular uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) (6 m), uncorrected intermediate visual acuity (UIVA) (60 cm), distance-corrected intermediate visual acuity (CIVA), uncorrected near visual acuity (UNVA) (40 cm), and corrected near visual acuity (CNVA) were assessed postoperatively on post operative day 30, for all four IOL groups. Defocus curve and contrast sensitivity were also compared.

Results:

With regards to UDVA and CDVA, P value was not statistically significant. ( P = 0.534 and 0.421, respectively). EDOF group of IOLs had statistically significant better UIVA and CIVA than trifocal IOL group. ( P < 0.001, 0.012, <0.001) and EDOF group had statistically significant worse P value pertaining to UNVA and CNVA ( P < 0.001, 0.070, <0.001, 0.190). Pertaining to contrast sensitivity, EDOF group had better contrast sensitivity than Trifocal IOL group (P < 0.001).

Conclusion:

All four IOLs compared in this study had good comparable distant visual acuity. Near visual acuity was better with AT LISA and Eyecryl SERT trifocal IOL while intermediate vision was better with Eyhance and Eyecryl SERT EDOF IOL. Contrast sensitivity was better in EDOF IOLs than in both trifocal IOLs.
