Clinical outcomes after femtosecond laser assisted cataract surgery with implantation of the tecnis symfony intraocular lens

Abstract:

AIM: To evaluate the clinical outcomes in terms of vision across distances(near, intermediate and far), contrast sensitivity and subjective patient satisfaction after femtosecond laser-assisted cataract surgery(FLACS)with implantation of an extended range of vision(ERV)intraocular lens(IOL).

METHODS: Forty patients(55 eyes)underwent bilateral or monocular FLACS with implantation of the ERV IOL Tecnis Symfony(Johnson & Johnson Vision)were enrolled. Uncorrected distance(UDVA), intermediate(UIVA)and near visual acuities(UNVA)were evaluated at 3mo after surgery, as well the defocus curve, contrast sensitivity, patient satisfaction and spectacle independence.

RESULTS:No severe complications occurred. All eyes showed a central position of the IOL in the capsular bag without tilting at 3mo after surgery. 3mo postoperative mean logMAR visual acuity at 5 m, 67 cm and 40 cm were -0.04 ±0.08, -0.17±0.22, 0.37±0.17, respectively. All patients obtained satisfactory UDVA and UIVA, as well as functional UNVA, meeting the needs of daily life. Spectacle independence rate was 94.55%. Contrast sensitivity results did not differ from those obtained with monofocal aspheric lenses. Likewise, no moderate and severe photic phenomena were reported. Mean patient satisfaction scores with distance, intermediate and near vision were 9.0, 9.0, and 7.0, respectively.

CONCLUSION: FLACS with implantation of the ERV IOL TECNIS Symfony provides a successful visual restoration at far, intermediate distance and a functional-range near vision acuity, with minimal level of disturbing photic phenomena, and high rates of spectacle independence and patient satisfaction.
