  • OBJECTIVE: To evaluate visual and subjective outcomes after diffractive intraocular lens (IOL) implantation in clear lens exchange.

    SETTING: Institut Català de Retina, Barcelona, Spain.

    METHODS: Prospective, non-interventional study of patients undergoing clear lens refractive surgery with implantation of a trifocal IOL. Subjective refraction and visual acuity were analyzed for uncorrected distant visual acuity (UDVA) and corrected distant visual acuity (CDVA) and for uncorrected near visual acuity (UNVA) and corrected near visual acuity (CNVA), 1, 3 and 6 months after surgery. Aberrometry was performed to determine the higher-order root mean-square (RMS). Bilateral contrast sensitivity function was obtained under mesopic conditions. The quality of visual function was evaluated using the VF-14 method.

    RESULTS: Mean monocular CDVA was 0.06 ± 0.07 logMAR and mean monocular UNVA was 0.02 ± 0.05  logMAR. Spherical equivalent (SE) 6 months after surgery was 0.03 ± 0.35 D. The safety index for distant vision was 1.0 and the efficacy index was 0.91.

    Mean higher-order RMS was 0.27 μm. Contrast sensitivity was lower in the postsurgery period, with values within normal ranges for adults. VF-14 value was 92.96.

    CONCLUSION: Diffractive trifocal IOL implantation after clear lens exchange is a safe and effective method that provides excellent outcomes and high quality visual function in distant and near vision.
