Clinical Outcomes of Implantable Contact Lens and Iris-Fixed Intraocular Lens for Correction of Myopia

Purpose: We compared the results of implanting an implantable contact lens (ICL) and an iris claw lens (Artisan® lens) in patients’ wtih myopia and sought to determine a basis for choosing between the two lenses. Methods: ICLs were implanted in 32 eyes of 18 patients, and Artisan® lenses were implanted in 40 eyes of 23 patients. Uncorrected visual acuity, refraction, endothelial cell density, intraocular pressure, and slit lamp measurements were taken for 12 months. Results: All the patients had improved UCVA from the day after the operation until the 12th month. The mean spherical equivalent refraction at postoperative month 12 was -0.78±0.54D in the ICL group and -0.78 ±0.59D in the Artisan® lens group. In the same period, endothelial cell density loss was 5.34% in the ICL group but was not significant in the Artisan® lens group. There were no significant complications in either group. Conclusions: Both ICL and Artisan® lens implantation resulted in immediate visual improvement and stability of vision during the follow-up period. There was no significant difference in post-operative results. Further study will be needed to decide which lens is the better choice for delicate conditions in myopic patients.
