PURPOSE: To evaluate the visual, refractive, contrast sensitivity, and aberrometric outcomes as well as the patient quality of life and photic phenomena disturbances after cataract surgery with implantation of a new trifocal toric intraocular lens (IOL). SETTINGS: Premium Clinic, Regional Hospital in Havlickuv Brod, Czech Republic, and Vissum and Universidad Miguel Hernández, Alicante, Spain. DESIGN: Prospective consecutive series of cases. METHODS: The study involved eyes with corneal astigmatism of 1.25 D or more that were having cataract surgery with implantation of the trifocal toric IOL AT Lisa tri toric 939MP (Carl Zeiss Meditec). Visual outcomes and astigmatic changes analyzed by Alpins vector analysis were evaluated at 3 months postoperatively. Contrast sensitivity, quality of life, and photic phenomena were also evaluated. RESULTS: The study involved a total of 30 eyes of 16 patients, age 37 to 64 years. A significant improvement with surgery was observed in uncorrected distance, intermediate, and near visual acuity (P ≤ .01). A significant decrease in the refractive cylinder was observed postoperatively (P < .01), with all eyes showing a postoperative astigmatism below 1.00 D. The difference between targeted and surgically induced astigmatism was small (0.06 ± 0.30 D) but statistically significant (P = .04). The mean magnitude of angle of error was 5.80 ± 8.47 degrees. The low levels of higher-order aberrations found postoperatively were consistent with the good levels of contrast sensitivity achieved. Regarding quality of life, low to moderate levels of difficulty in performing various types of vision-related tasks were found. CONCLUSIONS: The trifocal toric IOL evaluated provides effective restoration of visual function after cataract surgery, with associated high levels of visual acuities and quality of life.
