Long Term Effect of ICL Implantation to Treat High Myopia

Han, Sang Youp; Lee, Kyung Hun

Abstract

PURPOSE: We have investigated the long term effect, stability, predictability and complication of ICL implantation to treat high myopia.
METHODS
We investigated retrospectively in 176 eyes of 97 patients with spherical equivalent -11.91D (-6D~-23D) that were followed up for at least 6 months after ICL implantation.
RESULTS
Mean spherical equivalent was maintained stable as -0.54D at 1 week post-operatively, and at -0.55D for 5years. There was high effect and predictability, with 92.3% of the eyes exhibiting a greater than or equal to best corrected visual acuity (BCVA), 83% of eyes having a post-operative uncorrected visual acuity (UCVA) of 0.5 or better, 91.3% having a post-operative refraction of -1.0D~+1.0D, and 86.4% having a post-operative refraction of -0.5D~+0.5D. The most common complications were glare and halos. With a temporary increase in IOP, significant endothelial cell loss was observed. Repositioning for a dislocated ICL was done in 3 eyes. Post-operative cataracts were found in 7 eyes (3.9%), which was a significant increase in incidence, but not surprising, as the patients were older and had lower Vaulting values.
CONCLUSIONS
ICL implantation to treat high myopia was an effective surgery with good predictability and stability, and effective in both short term and long term follow-up periods.
