Abstract:AIM: To study the causes of complications in the application ofNd:YAG laser and provide the treatment and prevention.
METHODS: There were 387 cases(597 eyes)injured on ocular tissues by laser blasting, and the damage included inflammatory reaction, transient high intraocular pressure, corneal endothelial punctate opacity, anterior chamber hyphema, intraocular lens injury, and etc. The related values were dealt with quantitative processing.
RESULTS: Glaucoma iris perforation: inflammatory reaction in 93.7%, transient high intraocular pressure in 78.9%, anterior chamber hyphema in 23.7%, posterior synechia in 2.63%, iridodialysis in 0.53%, retinal hemorrhage in 0.53%. Intraocular lens anterior membrane incision: inflammatory reaction in 20%, transient high intraocular pressure in 33.3%, anterior chamber hyphema in 46.7%, intraocular lens injury in 33.3%. Intraocular lens posterior capsule incision: inflammatory reaction in 19.2%, transient high intraocular pressure in 17.8%, anterior chamber hyphema in 0.3%, intraocular lens injury in 26.0%.
CONCLUSION: It is safe to use Nd:YAG laser in the treatment of anterior segment. The ocular tissue damage is related with the performance of the machine, the types and degree of the diseases, and the cooperation of the patients. Learning these will help to avoid and decrease the ocular tissue damage.
