Trifocal aspheric diffractive IOL improves near, intermediate and distance vision

A trifocal aspheric diffractive IOL restored vision at different distances after microincision cataract surgery, according to a study.

The prospective study included 40 eyes of 20 patients with bilateral cataract. Patients underwent sutureless microincision cataract surgery and implantation of a FineVision IOL (Physiol) through a 1.8-mm corneal incision.

Investigators assessed monocular and binocular ETDRS visual acuity, refractive status, defocus curve and contrast sensitivity 1 month and 6 months after surgery.

Monocular logMAR uncorrected distance visual acuity improved significantly, from 0.70 preoperatively to 0.18 at 6 months (P < .001). Monocular corrected distance visual acuity improved significantly, from 0.24 preoperatively to 0.05 at 6 months (P < .001).

Monocular distance corrected near visual acuity improved significantly, from 0.24 preoperatively to 0.16 at 6 months (P = .020).

Mean monocular distance corrected intermediate visual acuity at 6 months was 0.17 at 80 cm.

The binocular defocus curve at 6 months was 0.09 logMAR at a –1.50 D defocus.

Monocular contrast sensitivity under scotopic conditions was within normal parameters for patients older than 60 years.
