Abstract
Purpose::
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).
Methods::
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.
Results::
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.
Conclusions::
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.
