Abstract
Correcting moderate and high myopia with phakic intraocular lenses offers a predictable and stable refractive results. This study was conducted to evaluate the efficacy, safety, predictability and stability of one of the phakic angle-supported anterior chamber lenses (pkakic-6) in correction of moderate and high myopia. The lens was implanted in 70 eyes of 40 patients with preoperative myopia ranged from -7.5 to -25D. Mean patient age was 30.36 5.6 years and all patients were followed up for at least 24 months. Postoperative refraction at the last follow up examination was within 0.68D of emmetropia. This refraction remained stable during the entire follow up period. The mean preoperative BCVA improved from 6/24 to 6/12 postoperatively with an efficacy index equal 1.5%. Central corneal endothelial cell density was significantly decreased at one month postoperatively (p<0.0001). The percentage of cell loss was maximum after one month (1.88%) and decreased to (0.44%) at the end of the first year and down to 0.3% at the end of the second year. The total cumulative loss of central endothelial cells after 2 years was 4.07%. Explanation of PIOL was performed in 2 eyes (2.9%) due to irreversible pupillary block. Mild ovalization of the pupil was recorded in 3 eyes (4.3%) and retinal detachment in 2 eyes (2.9%). The previous data showed that implantation of this type of angle-supported phakic anterior chamber intra-ocular lens to correct moderate and high myopia resulted in a stable and fairly predictable refractive outcome with limited complication.
