Abstract: :
Purpose: To observe the effect of Nd:YAG vitreolysis on the anterior vitreous opacity after cataract surgery. Methods: Forty nine pseudophakic eyes of 47 patients with the anterior vitreous opacity underwent slit lamp examination, optical coherence tomography, and B-scan. The anterior vitreolysis and posterior capsulotomy were performed simultaneously with Nd:YAG laser. The visual outcome and complications were studied. Results: Of 49 eyes, the anterior vitreous opacity associated with posterior capsule opacification was seen in 46 eyes and without posterior capsule opacification in 3 eyes. An opening was made in the opaque anterior vitreous behind the intraocular lens with vitreolysis of Nd:YAG laser. In all cases, the visual acuity improved significantly after laser procedure. The only complication was transient increase in the intraocular pressure in 4 cases (8.2%). In seven cases posterior capsulotomy was performed and visual acuity was checked, then anterior vitreolysis was performed. There was a statistically improvement in vision after vitreolysis compared to posterior capsulotomy alone (P=0.007). Conclusions: In pseudophakic eyes, visually significant anterior vitreous opacity may be seen in addition to the posterior capsular opacity. Opening of the opaque anterior vitreous with Nd:YAG vitreolysis is safe and improves the vision in these patients.
