PURPOSE: To report two cases of zonular dehiscence two years after phakic refractive lens (PRL) implantation. METHODS: In case 1, a 31-year-old myopic patient with refraction of -12.75 diopters (D) in the right eye and -20.50 D in the left eye, a 12-mm white-to-white measurement, and anterior chamber depth (ACD) of 3.7 mm underwent implantation of a -11.0 D and a -15.5 D PRL-101. Two years after surgery, a temporal-superior PRL decentration was observed in the left eye. In case 2, a 48-year-old pseudophakic patient with refraction of +8 -2.5 x 20 degrees underwent implantation of a piggyback PRL-200. Two years after surgery, an inferior PRL decentration was observed. RESULTS: The PRL was explanted in both cases. A zonular dehiscence was found--temporal-superior in case 1 and inferior in case 2. CONCLUSIONS: We have stopped implanting PRLs for the present time as the cause of this complication has yet to be determined.
