In-vivo Imaging of IOL Damage After Nd:YAG Laser Treatment

Objective: The use of specular microscopy to photograph in-vivo intraocular lens defects produced as a result of Nd-YAG laser posterior capsulotomy. Patients: Thirty randomly selected patients following Nd-YAG laser posterior capsulotomy. IOL: Lathe cut PMMA planoconvex. Results: IOL damage was found in 28 (93%) of IOLs. The most common damage was a crater with melted margins, craters with irregular margins and inclusions are also seen. Stellate defects in the intraocular lens were found in two cases. Conclusion: Specular microscopy performed during and after Nd-YAG laser capsulotomy demonstrates various kinds of intraocular lens defect.
