OBJECTIVE: To investigate the clinical effect of accommodating intraocular lens (IOL) on the accommodation of patients with IOL implantation.
METHODS: 75 cases (94 eyes) had phacoemulsification and implantation of Human-Optics accommodating 1CU intraocular lens. The main outcome measures were subjective refraction, uncorrected distance vision acuity, spectacle-free near visual acuity, best corrected distance vision acuity, distance corrected near vision acuity at 30 cm, best corrected near vision acuity at 30 cm, and amplitude of accommodation with subjective techniques of pushing-up test (near point) and defocusing with minus glasses. Patients were being follow-up for 1 to 12 months, the data was collected at 7, 30 and 90 days after surgery.
RESULTS: Postoperatively, better uncorrected distance vision acuity, best corrected distance and near vision acuity were obtained in all of patients studied. At different time points after surgery near visual acuity with Jaeger 5 or better without spectacle was 81.9%, 85.1%, and 84.0% at 7 days, 30 days and 90 days respectively. The near visual acuity with Jaeger 5 or better after distance vision acuity correction in all of cases was 78.7% at 7 days, 79.8% at 30 days and 74.5% at 90 days. The amplitude of accommodation was (1.96 +/- 0.63) D (range 0.75 to 4.50 D) by push-up test, (1.74 +/- 0.59) D (range 0.75 to 4.50 D) by defocusing at 7 days; (1.68 +/- 0.47) D (range 0.75 to 3.25 D) by push-up test, (1.89 +/- 0.54) D (range 0.75 to 3.25 D) by defocusing at 30 days; (1.77 +/- 0.53) D (range 0.75 to 2.75 D) by push-up test, (1.66 +/- 0.50) D (range 0.75 to 2.75 D) by defocusing at 90 days. The differences in amplitude of accommodation among 7, 30 and 90 days were not statistically significant (P > 0.05). Distance corrected near acuity and amplitude of accommodation showed a positive correlation.
CONCLUSION: The implantation of 1CU accommodative IOL provided both better distance and near vision acuity.
