To evaluate visual acuity and refractive outcomes in the treatment of high myopia with laser assisted in situ keratomileusis and the Visian® implantable contact lens (ICL).
A retrospective review was performed evaluating visual and refractive outcomes of 110 eyes with high myopia (>-6.00D preoperative spherical equivalent refraction) that underwent LASIK or Visian® ICL placement by four surgeons at the Kellogg Eye Center. The mean preoperative spherical equivalent for was -7.68D for those eyes that received LASIK and -11.08D for the phakic ICL group. Uncorrected visual acuity, best corrected visual acuity, and refraction outcomes were recorded from available postoperative examinations at 1 day, 1 week, 1 month, 3 months, and 6 months.
At 6 months, 49% of LASIK eyes had an UCVA of 20/20 or better and 89% had an UCVA of 20/40 or better. 95% of LASIK eyes had a BCVA of 20/20 or better at 6 months and all LASIK eyes had a BCVA of 20/25 or better. At 6 months, 75% of LASIK eyes were within plus or minus 0.50D spherical equivalent of target correction, 89% were within plus or minus 1.00D.At 1 month, 3/5 phakic ICL eyes had an UCVA of 20/20 or better, one patient measured 20/25. The remaining eye was left myopic for the purposes of monovision with an uncorrected near visual acuity of Jaeger 1. 4/5 ICL eyes had a BCVA of 20/20 or better, one eye had a BCVA of 20/25. All phakic ICL eyes were within plus or minus 0.50D spherical equivalent of target correction. No significant surgical complications were identified in either group.
Both refractive surgery methods for the correction of high myopia demonstrated favorable visual and refractive outcomes. Additional experience including longer follow-up evaluation is warranted for the phakic ICL group.
