PURPOSE: To evaluate the clinical outcomes obtained after cataract or crystalline lens surgery with implantation of a new continuous transitional focus intraocular lens (IOL).
SETTING: San Rafael Hospital, Madrid, Spain.
DESIGN: Nonrandomized prospective case series.
METHODS: Uncomplicated phacoemulsification cataract surgery was performed with bilateral implantation of the continuous transitional focus IOL Precizon Presbyopic. Visual, refractive, and contrast sensitivity outcomes were evaluated during a 6-month follow-up. Likewise, the incidence of postoperative disturbing photic phenomena was recorded.
RESULTS: Sixty-two eyes of 31 patients (mean age: 61.3 years) were enrolled. Mean 6-month postoperative binocular uncorrected distance (UDVA), intermediate (UIVA), and near visual acuity (UNVA) were 0.01 ± 0.03, 0.17 ± 0.04, and 0.02 ± 0.04 logarithm of the minimum angle of resolution (logMAR), respectively. A total of 98.4% (61) and 93.5% (58) of eyes achieved 20/25 monocular UDVA and UNVA or better, respectively, whereas all eyes (100%) achieved 20/30 UIVA or better. Mean corrected visual acuity of 0.14 ± 0.05, 0.15 ± 0.06, and 0.19 ± 0.02 logMAR were obtained for the defocus levels of -1.00, -1.50, and -2.00 diopters. Mean 6-month postoperative log contrast sensitivity was 1.22 ± 0.18 and 0.75 ± 0.10 for 12 and 18 cycles per degree, respectively. A total of 9.7% (3) and 6.5% (2) of patients reported disturbing halos and glare.
CONCLUSIONS: This presbyopia-correcting IOL provided a complete visual rehabilitation after cataract surgery, maintaining excellent levels of visual quality. Specifically, the IOL generated a continuous range of functional vision from distance to near, with minimal levels of photic phenomena associated.
