Descemet stripping automated endothelial keratoplasty in phakic eyes: incision modification reducing cataract formation
Journal Title: International Journal of Ophthalmology - Year 2018, Vol 11, Issue 1
Abstract
"AIM: To evaluate the efficacy of a technical modification to reduce the incidence of traumatic cataract induced by Descemet stripping automated endothelial keratoplasty (DSAEK) performed in phakic eyes. METHODS: A retrospective cohort study. The records of all patients with a clear crystalline lens and endothelial failure that underwent modified DSAEK at our insitution were reviewed. In this modification, in order to avoid inadvertent touch of the insertion forceps against the exposed crystalline lens while passing across the anterior chamber, the incision sites were shifted from the standard 9 and 3 o’clock positions, superiorly to the 10 and 2 o’clock position respectively. Formation of typically traumatic, anterior subcapsular cataract in these patients was compared to that observed in a cohort including all the patients with a clear crystalline lens and endothelial failure that underwent conventional DSAEK at our institution. RESULTS: The study group included 49 eyes following modified DSAEK and the control group included 35 eyes following DSAEK with conventional incision sites. Anterior subcapsular cataract occurring 4mo or less postoperatively was identified in 2 of 49 (4%) eyes in the study group and 7 of 35 (20%) eyes in the control group. The rates of traumatic cataract were significantly higher in the control group in comparison to the study group (P=0.03, RR=4.9, 95%CI 1.08-22.1). CONCLUSION: Traumatic cataract formation following phakic DSAEK may be avoided with a simple modification to the position of the incision sites."
