Clinical outcomes of cataract surgery with implantation of a continuous transitional focus intraocular lens.

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.
