영문 초록

Purpose: To study target refraction to improve visual quality in patients implanted with ReSTOR? SN6AD1 IOL (intraocular lens). Methods: This study included 128 patients (160 eyes) that had undergone cataract surgery and who had a far visual acuity score higher than 0.8 after 6 months. These patients were divided into 4 groups. The uncorrected visual acuity (UCVA) at far and near were greater than 0.8 and better than J1 in the first group (Group 1), greater than 0.8 and worse than J1 in the second group (Group 2), less than 0.8 and better than J1 in the third group (Group 3) and less than 0.8 and worse than J1 in the last group (Group 4). We also compared the postoperative refractive errors of the four groups. Results: At 6 months postoperatively, the spherical equivalent (SE) was -0.12 ± 0.51 in Group 1, 0.08 ± 0.54 in Group 2, -0.60 ± 0.60 in Group 3 and 0.02 ± 0.73 in Group 4. The SE value of Group 3 was significantly different compared to those of the other groups. Groups 1 and 3 who had better visual acuity at near distance show a negative value of SE, and Groups 3 and 4 who had worse visual acuity at far distance contained more individuals with an absolute value of SE greater than 0.5 compared to those in Groups 1 and 2. Conclusions: The refractive power in multifocal IOL insertion is different from that used in monofocal IOL insertion. As the SE indicates a greater myopic shift, the visual acuity is better at near distance, and, when the absolute value of SE is greater than 0.5, the visual acuity at far distance is decreased.
