Abstract
OBJECTIVE: To assess the efficacy and safety of Nd: YAG laser in clearing the anterior fibrinous membrane of posterior chamber intraocular lens (IOL). METHODS: Twenty-four eyes with the anterior fibrinous membrane of posterior chamber IOL were treated by Nd: YAG laser with the principle of "Low energy and de-focus" from 1997 to 1999 in Peking Union Medical College Hospital. Visual acuity, intraocular pressure (IOP) and anterior segment of the eye were followed after the laser treatment. RESULTS: Nd: YAG laser successfully cleared the anterior fibrinous membrane of IOL and IOLs were not damaged in all 24 eyes. The visual acuity was improved in 83.3% of the eyes. The IOP temporarily raised to above 21 mm Hg in 37.5% of the eyes. Topical steroids were used for the control of the intraocular inflammation in anterior segment after laser treatment. CONCLUSION: The anterior membrane of IOL can successfully and safely be cleared by Nd: YAG laser with the principle of "low energy and de focus".
