Abstract Details

Purpose:

To describe the refractive and functional results of one patient presenting a unilateral traumatic cataract and implanted with a non-diffractive presbyopia correcting intraocular lens (AcrySof Vivity DFT015).

Setting:

OMIQ-Institut Oftalmologia Mèdica i Quirúrgica - Barcelona - Spain

Report of Case:

44 years old patient that had undergone bilateral LASIK 13 years ago (RE -4.25 -1.75x140º=0.6 decimal // LE +0.50 -1.75x80º=1.0 decimal). Clinical history shows that RE presents known amblyopia with a best visual acuity (VA) of 0.6 decimal. At the moment of the diagnostic visit, the patient presented a traumatic cataract in RE with a UCVA <0.05 decimal in RE and 1.0 in LE. We performed a visual function questionnaire (VFQ-25), topography, biometry, endothelial count and macular OCT. We used the ASCRS IOL calculator for postop myopic refractive surgery (http://iolcalc.ascrs.org/). Informed consent was obtained according to specific cataract surgery and additional consent to disseminate his results to the scientific community. The surgery was performed according to the standard cataract procedure implanting an AcrySof Vivity DFT015 IOL of 20D without complications. One-week postoperative, uncorrected decimal visual acuities (distance / intermediate (66cm) / near (40cm)) were for the RE 0.8 / 0.6 / 0.6 decimal and LE 1.0 / 1.0 / 1.0. Binocularly 1.0 / 1.0 / 1.0. Refractive refraction in the RE was +0.25-0.50x180 (not improving VA). The patient satisfaction was very high, showing a very good visual integration with the contralateral eye that still have accommodative function. Results at 1 month and 3 months follow-up will be included in the last version of the presentation, including a satisfaction questionnaire and visual disturbance analysis with the “Light Distortion Analyzer” device.

Conclusion/Take Home Message:

This case shows how the AcrySof IQ Vivity DFT015 can be a good option in cases in which diffractive trifocal IOLs are not a clear indication. Diffractive based IOLs, as they split the wavefront, can induce a decrease of contrast sensitivity and increase the perception of visual disturbances. AcrySof IQ Vivity DFT015 IOL do not split the wavefront and do not induce this kind of effects as, in distance vision, it provides a similar behavior than a monofocal IOL with the advantage of a good intermediate and a functional near vision. This project received a grant from Alcon for the dissemination of results
