[Does peripheral iridectomy increase the risk of retinal detachment in patients with aphakia or pseudophakia?]

A retrospective study of 107 cases of retinal detachment in aphakic and pseudophakic eyes showed different types of retinal break depending upon surgical method. Three techniques were studied: intracapsular extraction (ICCE), intracapsular extraction with anterior chamber lens implant (ICCE, AC-IOL), and extracapsular extraction with posterior chamber lens implant (ECCE, PC-IOL). Results were compared for each technique with and without peripheral iridectomy. Typical aphakic and pseudophakic retinal breaks were found only in eyes having undergone peripheral iridectomy: our conclusion is that peripheral iridectomy is a risk factor for typical retinal breaks.
