To determine whether residual hyperopia could be corrected postoperatively using the light adjustable lens technology in patients undergoing cataract surgery and light adjustable lens implantation.
Prospective, nonrandomized clinical trial.
Fourteen eyes of 14 patients were studied. The manifest refraction, uncorrected visual acuity (UCVA), and best-corrected visual acuity (BCVA) were determined with follow-up time to determine the achieved refractive corrections and their stability.
Of 14 eyes, 13 eyes (92.9%) achieved +/- 0.25 diopters (D) of the target refraction at one day post lock-in, with 100% of the eyes achieving the targeted refractive adjustment within 0.5 D or better up to six months postoperative follow-up. All eyes treated show no change in manifest spherical refraction >0.25 D between one day post lock-in, and three and six months postoperative visits. The data demonstrate the stability of the achieved refractive change after the adjustment and lock-in procedures. The mean rate of change was 0.006 D per month, which is six times more stable than that of refractive procedures.
Residual hyperopia errors in the range of +0.25 to +2.0 D were successfully corrected with precision and significant improvement in UCVA and without compromising BCVA using the light adjustable intraocular lens technology.
确定在接受白内障手术和可调节人工晶状体植入的患者中，使用光可调人工晶状体技术能否在术后矫正残余远视。
前瞻性、非随机临床试验。
对14例患者的14只眼进行研究。通过随访确定明显验光、未矫正视力（UCVA）和最佳矫正视力（BCVA），以确定所实现的屈光矫正及其稳定性。
14只眼中，13只眼（92.9%）在锁定后一天达到目标屈光度±0.25 屈光度（D），在术后6个月的随访中，100%的眼睛在0.5 D或更好的范围内达到目标屈光调整。所有接受治疗的眼睛在锁定后一天、术后3个月和6个月的随访中，明显球镜屈光度变化均未超过0.25 D。数据表明调整和锁定程序后所实现的屈光变化具有稳定性。平均变化率为每月0.006 D，比屈光手术稳定6倍。
使用光可调人工晶状体技术成功精确矫正了+0.25至+2.0 D范围内的残余远视误差，显著提高了UCVA，且未损害BCVA。
