PURPOSE: To compare endothelial cell (EC) variation after anterior chamber phakic intraocular lens (AC-pIOL) implantation in highly myopic @entity1 with a preoperative @entity8707 ( @entity8707 ) between 2.8 and 3.0 versus >= 3.0 mm. METHODS: A total of 280 eyes submitted to primary AC-pIOL implantation were analyzed. Pre- and postoperative values for uncorrected distance visual acuity, corrected distance visual acuity, spherical equivalent, @entity8707 (endothelial surface), and EC count were collected. The eyes were divided into 2 groups: group A - @entity8707 between 2.8 and 3.0 mm; group B - @entity8707 >= 3.0 mm. Mean global EC loss (ECL) and loss for each @entity8707 group, according to pIOL type, were analyzed. RESULTS: Significant improvement of the spherical equivalent (-11.38    4.57 vs. -0.49    0.79; p = 0.000) and a significant decrease in EC density (2,810.95    343.88 vs. 2,584.09    374.88 cells/mm2; p = 0.000) were noted. The mean annual ECL was -2.19    3.97%. Regarding group A (n = 80), a mean annual ECL of -2.06    3.88% was registered, higher for the Acrysof Cachet   subtype, while group B (n = 200) showed -2.25    4.01% ECL, higher for the Verisyse   subtype. There was no significant difference between the groups (p = 0.96). CONCLUSIONS: AC-pIOL implantation significantly improves the spherical equivalent in myopic @entity1 . The mean annual ECL after pIOL implantation was higher in the larger @entity8707 group, but this value was not statistically significant. A 2.8-mm @entity8707 value seems to be a safe cutoff for AC-pIOL implantation.
