  • Look Inside

Purpose : To evaluate the inflammation following cataract surgery using pigment dispersion in the chamber angle as a parameter.

Cases : Small-incision cataract surgery by phacoemulsification and aspiration was performed on 86 eyes. Gonioscopy was performed before and up to 6 months after surgery. The pigment dispersion was graded after Scheie.

Results : Postoperatively, 38 eyes showed increased pigmentation in the chamber angle and 48 eyes did not. The former 38 eyes were often associated with, as risk factors, longer duration of surgery, use of heparin-coated intraocular lens, presence of diabetes mellitus and heavy pigmentation before surgery. These 38 eyes showed more intense aqueous flare after surgery than the other 48 eyes. The difference was significant up to postoperative 3 months. There was no difference between the two groups regarding postoperative intraocular pressure or corneal endothelial loss.

Conclusion : Postoperative inflammation is a liability needing preventive measures when above risk factors for pigment dispersion are detected prior to cataract surgery.
