Objectives:
To evaluate the movement from their initial set position of subluxated intraocular lenses (IOL) in pig eyes following Nd: YAG laser capsulotomy.
Methods:
An extracapsular surgical intervention of the transparent crystalline lens was performed on 15 pig eyes. After the introduction of an intraocular lens into the capsular sac, a zonular dialysis was carried out to observe the shift of the IOL. We carried out a high intensity Nd: YAG laser capsulotomy in a 3.5mm cross shape in the central optical axis and then measured the final displacement of the IOL using a millimetre ruler.
Results:
We did not observe a significant shift of the lens in any of the eyes studied.
Conclusions:
Nd: YAG laser capsulotomy is a safe short-term operation for static and subluxated intraocular lenses.
