To assess the safety, efficacy, and predictability in eyes that had refractive lens exchange (RLE) with implantation of a spherical diffractive intraocular lens (IOL) after previous hyperopic laser in situ keratomileusis (LASIK).
Fernández-Vega Ophthalmological Institute, Oviedo, Spain.
This prospective study evaluated eyes that had RLE and implantation of an AcrySof ReSTOR SN60D3 IOL after hyperopic LASIK. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA), and residual refractive errors were analyzed using vector analysis and recorded preoperatively and 6 months postoperatively.
The study evaluated 41 eyes of 23 patients. The mean UDVA was 0.189 logMAR +/- 0.175 (SD) preoperatively and 0.113 +/- 0.101 logMAR 6 months postoperatively (P = .009) and the mean CDVA, 0.049 +/- 0.071 logMAR and 0.046 +/- 0.063 logMAR, respectively (P = .44). At 6 months, the efficacy index was 0.87 and the safety index, 1.00. The mean UNVA was 0.014 +/- 0.026 logMAR, with an efficacy index of 1.00. There were no differences in corrected near visual acuity between preoperatively (with spectacle addition) and postoperatively (P = .3); the safety index was 1.01. All eyes were within +/-1.25 diopters (D) of the targeted refraction and 73.17% were within +/-0.50 D. The mean postoperative spherical equivalent was -0.064 +/- 0.513 D.
Implantation of a spherical multifocal IOL after hyperopic LASIK was safe, effective, and predictable.
评估既往接受过远视性准分子原位角膜磨镶术（LASIK）后行屈光性晶状体置换术（RLE）并植入球面衍射人工晶状体（IOL）的眼睛的安全性、有效性和可预测性。
西班牙奥维耶多的费尔南德斯 - 维加眼科研究所。
这项前瞻性研究评估了接受远视性LASIK术后行RLE并植入AcrySof ReSTOR SN60D3 IOL的眼睛。使用矢量分析术前和术后6个月分析未矫正远视力（UDVA）、矫正远视力（CDVA）、未矫正近视力（UNVA）、远距矫正近视力（DCNVA）和残余屈光不正，并进行记录。
该研究评估了23例患者的41只眼睛。术前平均UDVA为0.189 logMAR±0.175（标准差），术后6个月为0.113±0.101 logMAR（P = 0.009），平均CDVA分别为0.049±0.071 logMAR和0.046±0.063 logMAR（P = 0.44）。在6个月时，有效性指数为0.87，安全性指数为1.00。平均UNVA为0.014±0.026 logMAR，有效性指数为1.00。术前（加用眼镜）和术后矫正近视力无差异（P = 0.3）；安全性指数为1.01。所有眼睛的屈光度数均在目标屈光度±1.25 屈光度（D）范围内，73.17%在±0.50 D范围内。术后平均球镜等效度为 -0.064±0.513 D。
远视性LASIK术后植入球面多焦点IOL是安全、有效且可预测的。
