Neodymium:YAG laser capsulotomy in vitrectomized pseudophakic eyes with persistent endotamponade.

Purpose: To evaluate the feasibility and limits of neodymium:YAG (Nd:YAG) laser capsulotomy in eyes with persistent endotamponade.

Setting: Department of Ophthalmology, University Cologne, Cologne, Germany.

Methods: In this consecutive series, an Nd:YAG laser capsulotomy was performed by 1 surgeon in 6 eyes with posterior capsule opacification (PCO) and persistent endotamponade caused by proliferative vitreoretinopathy. The endotamponade was with silicone oil (5000 centistokes) in 5 eyes and with perfluorohexyloctane (F(6)H(8)) in 1 eye. Also evaluated were 6 vitrectomized eyes without endotamponade that had an Nd:YAG laser capsulotomy for PCO by the same surgeon. All 12 eyes were pseudophakic. The mean follow-up after capsulotomy was approximately 6 months (range 2 to 12 months). Follow-up examinations included visual acuity, intraocular pressure measurement, and IOL centration and capsule reopacification evaluation.

Results: The total energy required was higher in eyes with persistent endotamponade. In 3 of these eyes, the laser capsulotomy could not be successfully completed and was surgically enhanced. The laser capsulotomy in eyes without endotamponade was successful in all cases. Complete reopacification occurred in 2 eyes with persistent endotamponade within 2 months and in no eye without endotamponade. Improvement in visual acuity was limited in all eyes because of retinal pathology.

Conclusions: Neodymium:YAG laser capsulotomy in pseudophakic eyes with persistent endotamponade was successful but had a relatively high reintervention rate. The visual prognosis was limited in all cases because of retinal pathology.
