Intraindividual Comparison of ICL and Toric ICL Implantation in the Correction of High Myopia With Astigmatism

Purpose: We compared intra-individual visual outcomes and patient satisfaction after implantable contact lens (ICL) and Toric ICL implantation. Methods: Twenty-eight eyes of 14 patients were enrolled in this retrospective study. One eye of each patient was assigned to ICL (ICL Group), and the contralateral eye was allocated to Toric ICL (Toric ICL Group). All patients were examined for visual acuity, refraction, intraocular pressure, slit lamp measurements, and satisfaction one week, one month, two months, and six months postoperatively. Results: Mean spherical equivalents of the two groups were corrected from -7.83D (ICL Group) and -5.55D (Toric ICL Group) to 0.13D and 0.20D, respectively, and the mean refractive cylinders were corrected from 0.92D and 2.60D to 0.42D and 0.27D, respectively, at six months postoperatively. The myopias of these two groups and the astigmatism of the Toric ICL group were effectively corrected. The uncorrected visual acuity (UCVA) of the two groups were 1.02 and 1.05, respectively, at six months postoperatively. The safety index, efficacy index, predictability, and stability were favorable. There were no significant differences between the two groups in terms of postoperative UCVA, intraocular pressure(IOP), vaulting, noticeable complications, or patient satisfaction. Conclusions: The results show ICL implantation is effective treatment for high myopia, and Toric ICL implantation is a viable surgical option for the treatment of compound myopia astigmatism. Selection of proper phakic intraocular lens(IOL) is recommended for correcting astigmatism. J Korean Ophthalmol Soc 2010;51(6):802-808
