Abstract
Objective : study the effect of Nd -YAG Laser capsulotomy on corneal endothelium using y Specular microscope.
Patients and Methods: ophthalmological department at surgical specializations hospital / medical city Baghdad. Twenty patients having cataract extraction with posterior capsular opacification were divided into 2 groups ,10 patients for each; first group with cataract extraction and PC IOL (pseudophakic group), the second group with cataract extraction without IOL implantation, (aphakic group). both groups treated with Nd-YAG laser with approximately the same laser power used and number of shoots. Non-contact specular microscopy was performed at the center of the cornea for the eyes before and after laser (about one hour after performing laser).
Results: increase in mean cell surface area and decrease in % of hexagonality occurred in the two groups during examination and it appeared to be significantly higher in the aphakic group.
Conclusion: the scarcity of lesion following laser capsulotomy in pseudophakic eye suggests that the implant may act as barrier against particulate dispersion.
