Abstract

Purpose: To show the clinical outcomes after implantation of a diffractive trifocal intraocular lens (IOL) in eyes with previous laser-corneal-refractive-surgery (LCRS) or radial keratotomy (RK).

Methods: Eyes with previous LCRS (LASIK/PRK group) or RK (RK group) implanted with a diffractive trifocal IOL were enrolled in this retrospective study. Refraction and monocular Snellen decimal uncorrected-distance visual acuity (UDVA), corrected-distance visual acuity (CDVA), and uncorrected-near visual acuity (UNVA) were analyzed at 1-year.

Results: The current study comprises 124 eyes: 102 eyes for the LASIK/PRK group and 22 eyes for the RK group. In the LASIK/PRK group 92.16% of eyes were within ±0.50D and 99.02% within ±1.00D (mean spherical equivalent of -0.03±0.30D). 91.18% of eyes showed 0.50D or less astigmatism, and all of them 1.00D or less (mean refractive cylinder of -0.21±0.27D). In the RK group, 81.82% eyes were within ±0.50D and 100% within ±1.00D, with a mean SE of -0.17±0.38D. 68.18% eyes showed 0.50D or less residual astigmatism, and 95.45% eyes 1.00D or less, with a mean cylinder of -0.45±0.39D. The mean UDVA, CDVA and UNVA were 1.04±0.19, 1.14±0.20 and 0.99±0.04, respectively, for the LASIK/PRK group, and 0.90±0.10, 1.01±0.08 and 1.00±0.00, respectively, for the RK group. For the LASIK/PRK group 72.55%, 88.24% and 98.04% of eyes had 20/20 or better UDVA, CDVA and UNVA, respectively, with 96.08%, 100% and 98.04% of eyes achieving 20/25 or better for UDVA, CDVA and UNVA, respectively. For the RK group, the percentages changed to 45.55%, 83.36%, 100%, 90.91%, 100% and 100%, respectively.

Conclusion: The use of a diffractive trifocal IOL can provide good clinical outcomes in eyes with previous LCRS or RK.

既往激光角膜屈光手术或桡骨角膜切开术后使用三焦人工晶状体的临床结果：1年随访。

目的：观察曾行激光角膜屈光手术（LCRS）或桡骨角膜切开术（RK）的患者植入衍射三焦人工晶状体（IOL）后的临床效果。方法：回顾性研究既往LCRS （LASIK/PRK组）或RK （RK组）植入衍射型三焦人工晶状体的眼睛。1年时的屈光和单眼Snellen十位数未矫正距离视力（UDVA）、矫正距离视力（CDVA）和未矫正近视力（UNVA）进行分析。结果：本研究共纳入124只眼：LASIK/PRK组102只眼，RK组22只眼。LASIK/PRK组92.16%的眼在±0.50D范围内，99.02%的眼在±1.00D范围内（平均球等效为-0.03±0.30D）。91.18%的眼睛散光在0.50D及以下，全部在1.00D及以下（平均屈光柱为-0.21±0.27D）。RK组81.82%的眼睛在±0.50D范围内，100%的眼睛在±1.00D范围内，平均SE为-0.17±0.38D。残余散光在0.50D及以下的占68.18%，在1.00D及以下的占95.45%，平均柱面为-0.45±0.39D。LASIK/PRK组平均UDVA、CDVA、UNVA分别为1.04±0.19、1.14±0.20、0.99±0.04，RK组平均UDVA、CDVA、UNVA分别为0.90±0.10、1.01±0.08、1.00±0.00。LASIK/PRK组UDVA、CDVA和UNVA分别为72.55%、88.24%和98.04%，达到20/20及以上，UDVA、CDVA和UNVA分别为96.08%、100%和98.04%，达到20/25及以上。RK组分别为45.55%、83.36%、100%、90.91%、100%和100%。结论：对于有LCRS或RK病史的眼，应用衍射型三焦人工晶状体具有良好的临床效果。
