Abstract (Max 200 words)
|
|
Purpose:
|
To evaluate the long-term refractive and visual outcomes and complications associated with Implantable Collamer Lens (ICL) and toric ICL implantation to correct high myopia and astigmatism.
|
Methods:
|
Uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), refraction, and adverse effects were evaluated in 66 eyes of 31 high myopic patients after 5 years with Visian ICMV4 pIOL (STAAR Surgical Inc.).
|
Results:
|
The mean pre-operative spherical equivalent (SE) and cylinder changed from -11.74?5.36 diopters (D) and -2.35?1.58 D to -1.53?1.48 D and -0.82?0.69 D, respectively 5 years postoperatively. Before the surgery the mean Snellen decimal CDVA was 0.58?0.31. The mean UDVA and CDVA changed to 0.61?0.32 and 0.76?0.31, respectively. 56.7% of eyes achieved 20/40 or better UDVA postoperatively. The mean safety and efficacy indices were 1.29 and 1.04 respectively. No eye lost a line of visual acuity and 42 eyes gained one or more lines. 11% Endothelial cell loose was occurred. Transient high intraocular pressure was observed in 3 patients, and 4 eyes had needed realignment. Crystalline lens was clear during the study.
|
Conclusion:
|
ICL and toric ICL implantations were effective, predictable, and safe procedures over the long term follow up for the treatment of high myopia and high myopic astigmatism.
