The results of this study suggest that the Pentacam, Galilei, and Sirius Scheimpflug systems should not be accepted as interchangeable for CCT, TCT, ACD, and simK in healthy subjects.
Purpose: To report the therapeutic efficacy of an accidentally injected intralenticular sustained-release dexamethasone implant in a patient with macular edema secondary to branch retinal vein occlusion and shortly discuss the management strategy of this rare complication. Methods: Complete ophthalmological examination and optical coherence tomography imaging were performed at each visit. Results: The implant accidentally caused a posterior capsular tear during the procedure and was injected into the crystalline lens because of an involuntary head movement of the patient. Since the anterior segment was normal, and the resultant cataract and implant itself did not obscure the visual axis, the decision was made to observe the patient with intralenticular implant, preserve the therapeutic effect and avoid reinjection. The macular edema resolved within time, while visual acuity did not show significant improvement due to an increase in lens opacification. The patient underwent phacoemulsification surgery at 7 months after the injection with implantation of posterior chamber IOL into the capsular bag. Conclusion: Inadvertent injection of sustained-release intravitreal dexamethasone implant into the crystalline lens is an uncommon but possible complication that is mostly caused by surgeon inexperience, improper technique and uncontrolled head movement during the procedure. Once this complication occurs, early phacoemulsification and repositioning of the implant into the vitreous is the frequently preferred management strategy. However, remarkable decrease in macular edema and visual acuity improvement can also be achieved without an immediate surgical intervention.
Ciprofloxacin seems to be more effective in conjunctival sterilization. In consideration with high variety of bacterial flora in pretreatment period in ofloxacin group, ofloxacin seems to be superior to povidone-iodine on the reduction of bacterial flora on the conjunctiva.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
