Short-term results with the Synchrony lens implant for correction of presbyopia following cataract surgery

Resumen

OBJECTIVE: To evaluate the efficacy and safety of the Synchrony® dual-optic lens, for the correction of presbyopia following cataract surgery. SETTING: Fundación Oftalmológica del Mediterráneo. Valencia. Spain. METHOD: Prospective, non-comparative study of 18 patients (36 eyes) in whom a Synchrony® dual-optic lens was implanted bilaterally following cataract surgery. All patients were studied preoperatively, and 1, 3 and 6 months postoperatively. The following measurements were taken: Uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) for distance, intermediate and near vision, and the objective amplitude of accommodation using the OQAS™ system. RESULTS: The mean age of the group studied was: 74 ± 6 years. Of the 18 patients, 8 were men and 10 women. The mean postoperative distance BCVA improved significantly, from 0.27 ± 0.17 logMAR, (0.53 on the decimal scale) to 0.06 ± 0.21 logMAR (0.96) six months after surgery (p > 0.05). The mean addition required for near vision (reading at 40 cm) was 1.87 D after 1 month, 1.66 D after 3 months and 1.5 D after 6 months. The following postoperative objective amplitude of accommodation values were found: 2.25 ± 1.00, 2.17 ± 0.77 and 2.25 ± 0.83 D, after 1, 3 and 6 months, respectively. CONCLUSIONS: The Synchrony® dual-optic lens is a promising option for the treatment of presbyopia in patients following cataract surgery, due to its special design. However, new designs are required to improve this capability.
