Clinical Outcomes Using a Trifocal Intraocular Lens in Eyes After Previous Laser Corneal Refractive Surgery or Radial Keratotomy: 1-Year of Follow-Up.
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.
