COLOME CAMPOS, J.; ROMERO-AROCA, P.; QUEVEDO JUNYENT, Ll.  and  MARTINEZ-SALCEDO, I.. Experimental study of pig dislocated intraocular lens shift after Nd: YAG laser capsulotomy. Arch Soc Esp Oftalmol [online]. 2011, vol.86, n.5, pp.145-148. ISSN 0365-6691.

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.
