Bilateral implantation of a spiral optic intraocular lens (IOL) provided functional vision across distance, intermediate, and near ranges, with improvements in contrast sensitivity, visual disturbances, and patient-reported visual disability through 3 months, according to a study.
The study included 98 eyes of patients who underwent bilateral cataract surgery with the Galaxy IOL (Rayner). At 3 months, mean binocular corrected distance visual acuity was -0.08 logMAR, and distance-corrected intermediate and near visual acuity were -0.06 and 0.11 logMAR, respectively.
The binocular defocus curve showed functional vision of 0.2 logMAR or better from +1.00 to -2.50 D at both 1 and 3 months. Mesopic and photopic contrast sensitivity improved between 1 and 3 months across nearly all spatial frequencies (P ≤ 0.035). Halo and glare phenomena also decreased significantly during this period (P < 0.001).
Patient-reported visual disability was significantly reduced at both 1 and 3 months compared with baseline, based on Rasch Catquest 9SF scores (P < 0.001).
