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