To assess the safety and the effectiveness of intraocular anterior chamber implants in phakic eyes for myopic correction.
Retrospective assessment of spectacle corrected and uncorrected visual acuity, refraction, central endothelium density and incidence of postoperative complications. Fifteen eyes of 12 patients were fitted into the criteria of inclusiveness and were followed for a minimum of 6 months (average 25.8 months) after surgery.
There were no complications in this sample. The average spherical equivalent decreased from -l5.l5D to -0.77D after the surgery (p<0.001). Average postoperative uncorrected visual acuity was 20/34, and was at least 20/4 0 in 11 out of 13 eyes (85%) examined. No patient presented decrease in spectacle corrected visual acuity which improved in 8 of the 15 eyes (53%). No endothelium cell loss was detected. Endothelium density averaged 2719.4 cells/mm2 and 2774 cells/mm2 before and after the surgery, respectively (p>0.05).
While using the methodology this procedure proved to be safe and effective in this sample. Certainly, larger segments of the population should be evaluated to determine the long lasting clinical value of the procedure.
