Abstract:
Objective To observe the short-term visual effects of cataract surgery patients with 1CU accommodating intraocular lens (IOL) compared with aspheric monofocal IOL. Design Non-randomed comparative trial. Participants Consecutively 118 senile cataract patients (118 eyes). Methods 59 cataract patients (59 eyes) were implanted 1CU accommodating IOL (1CU group), and 59 cataract patients (59 eyes) were implanted aspheric monofocal IOL (Tecnis ZA9003 group). All patients were assessed at 3 months post-operation in the aberrations of crystalline, the modulation transfer function contrast sensitivity of 10/100 percent in three sorts distance(40, 63, 100 cm), uncorrected distanced visual acuity(UCDVA), uncorrected near visual acuity(UCNVA), best-corrected distance visual acuity(BCDVA), best-corrected near visual acuity(BCNVA), distance corrected near visual acuity(DCNVA), pseudo-accommodation, and the rate of off-near glasses. Main Outcome Measures Visual acuity, aberrations, modulation transfer function, contrast sensitivity, pseudo-accommodation, the rate of off-near glasses. Results At 3 months postoperatively, both UCNVA and DCNVA were significantly better in 1CU group than in the aspheric monofocal IOL group (t=8.85, P=0.00; t=13.05, P=0.00). The accommodative range was (2.58?0.37) D in 1CU group and (1.46?0.25) D in monofocal IOL group (t=14.33, P=0.00). In 3 mm and 5 mm pupil diameter the difference of the total aberration and spherical aberration in Tecnis ZA9003 group or 1CU group was significant (3 mm pupil t=18.48, P=0.00; t=5.70, P=0.00. 5 mm pupil t=19.98, P=0.00; t=6.70, P=0.00). At 40 cm and 63 cm, VA scores were higher in 1CU group (85%)than in Tecnis ZA9003 group (25%) (t=3.64, P=0.00; t=2.74, P=0.00; t=2.65, P=0.00; t=2.44, P=0.01). The rate of off-near glasses in 1CU group was better than in the aspheric monofocal IOL group(?2=41.95, P=0.00). Conclusions The 1CU accommodating IOL can provide better useful near visual acuity than aspheric monofocal IOL, especially for the patients who want to get rid of spectacles.
