Purpose: To evaluate refractive and visual outcomes and contrast sensitivity after cataract surgery with the implantation of AT LISA trifocal intraocular lens (IOL)

Methods: Patients had bilateral cataract surgery and multifocal diffractive IOL (AT Lisa tri 839 MP) implantation. A complete ophthalmology examination was performed preoperatively and postoperatively. The follow-up was 2 months. The main outcome measures were uncorrected distance (UDVA), intermediate, and near visual acuities, distance between visual axis and the center of the IOL and aberrations (total, corneal, internal).

Results: The study comprised 16 eyes of 8 patients (mean age 59 years ± 5.2 [SD]; range 49 to 80 years). There was significant improvement in uncorrected intermediate visual acuity, uncorrected near, intermediate and near visual acuity. The postoperative refractive status was within the range of +1.50 to -1.25 diopter. Total internal aberrations decreased significantly (P<.001). FACT™ Contrast Sensitivity Chart showed that contrast Sensitivity was below the normal distribution.

Conclusions: The trifocal IOL improved near, intermediate, and distance vision in presbyopic patients. The use of 3 foci provided significant intermediate visual results without sacrificing near or distance vision, however Contrast Sensitivity was below the normal distribution.
