Study of Complications of Phakic Intraocular Lenses in Correction of Myopia

Abstract

Objective: To evaluate the visual outcomes and complications of phakic intraocular lenses Implantation for myopia. Method: This cross sectional study included 151 myopic eyes implanted with one of the three types of phakic intraocular lenses (Artisan 83 eyes, ICL 52 eyes, and I- Care 16 eyes). Patients were followed for an average of 33±15 months. Intraoperative and postoperative complications were recorded as short- term and long-term. All patients were recalled and examined under thorough eye examination. Results: Three years after the surgery, safety index has changed significantly using the Artisan and ICL lenses respectively (P>0.001 and P 0.007=) and efficacy index in the three groups was 0.04 ± 0.91, 0.14± 1.61 and ± 0.42 0.15. Spherical Equivalent (SE) values decreased post operation that was statistically significant (P 001/0>) using Artisan and ICL lenses. Also, Astigmatism values dropped significantly using Artisan and I-care lenses (P 001/0> and P 03/0=) three years after surgery. Endothelial cell count reduction percentage was 6.1% and 5.2% in groups Arti san and ICL respectively, while it was 43.7% in Group ICare. Conclusion: No significant intraoperative complication was seen among the three groups. However, sharp decline of post operatively corneal endothelial cell count was the most important complication of I- Care lens and it is suggested to prevent implantation of this type of PIOLs for anticipation of cornea decompensation.
