To evaluate visual, refractive outcomes and quality of vision after implantation of the AT LISA tri 839MP intraocular lens.

This prospective case series study comprised 46 cataractous eyes of patients who underwent phacoemulsification with intraocular lens implantation (mean age of 58.08 ± 11.01 years; range 36 to 76 years). Spherical equivalent (SE), uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), corrected intermediate visual acuity (CIVA), uncorrected near visual acuity (UNVA), corrected near visual acuity (CNVA) were measured 1, 3 and 6 months after surgery. Contrast sensitivity (CS) was measured at 6 months. Subjective quality of vision and presence of dysphotopsia by a short questionnaire were evaluated postoperatively.

At 6 months, mean visual acuity were: 0.08±0.11, 0.03±0.08, 0.07±0.09, 0.02±0.08, 0.05±0.09 and 0.02±0.08 LogMAR for UDVA, CDVA, UIVA, CIVA, UNVA and CNVA, respectively. Mean values of SE were - 0.4728 ± 0.32 D. These variables improved over time but significant changes were detected in UDVA (P=0.009) and SE (P=0.0001). Mean CS value was 1.74 ± 0.08. Mean scores (0% = no symptoms; 100% = strong symptoms/unable to perform activities) for glare and halos were 7.07±0.22% and 8.70±0.23%, respectively. These phenomena reduced over time. Patients’ level of satisfaction mean score for performing activities was 96.66%.

The AT LISA tri 839MP intraocular lens provides excellent uncorrected distance, intermediate, near vision and contrast sensitivity. This intraocular lens showed minimal level of photic phenomena and high level of patient satisfaction.
