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.
Conclusion: 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. J Korean Ophthalmol Soc 48(4):465-472, 2007
