Abstract

PURPOSE
To assess the efficacy, predictability, stability and safety of the implantable contact lens (ICL) to treat high myopia METHODS: We retrospectively analyzed the clinical outcomes in 49 eyes of 28 patients with high myopia undergoing ICL implantation with a minimum follow-up period of 3 months. RESULTS: Mean preoperative spherical equivalent was -13.94 +/- 5.47D (range, -25.50 to -7.25D), and mean postoperative spherical equivalent was -1.59 +/- 1.59D (range, -6.38 to +0.50D). Forty one eyes (83.7%) were within 1.0D, and 29 eyes (59.2%) were within 0.5D of predicted refraction at last exam. Postoperative uncorrected visual acuity at last examination was 0.5 or better in 43 eyes (87.8%) and 1.0 or better in 21 eyes (42.9%). A gain of 1 or more lines of best corrected visual acuity was seen in 19 eyes (38.8%) and a lost 1 or more lines of best corrected visual acuity at last time in 7 eyes (14.3%). The refraction remained stable with a statistically insignificant change (p>0.05) at each interval during follow-up. Glaucoma occurred in 3 eyes (6.1%), and pigment deposited on the ICL in 5 eyes (10.2%). Two ICLs (4.1%) of 1 patients were removed due to glare. CONCLUSIONS: ICL Implantation is predictable, stable, and effective in the correction of high myopia, with good short-term safety.
