Analysis and treatment of explicit and occult Descemet's membrane detachment after phacoemulsification / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: The reasons of explicit and occult Descemet's membrane detachment ( DMD ) after phacoemulsification were analyzed and the therapeutic measures were further provided. METHODS:A total of 31 cases diagnosed as explicit and occult DMD between Jan. 2013 and Apr. 2016 received the injection of sterile air into anterior chamber by 1-3 times, and were followed up for 3mo to observe the recoveries of cornea. RESULTS: A total of 30 cases recovered with no visual impairment and other related complications. One case which refused being treated resulted in bullous keratitis.CONCLUSION:Both the internal and external factors can influence the operation effect of explicit and occult DMD after phacoemulsification. Early detection and timely treatment play important roles in improving patients'visual acuity. Early examination of anterior segment OCT or UBM for intractable corneal edema is helpful to find the occult DMD with different degree and work out the targeted therapies.

Application of capsular tension ring combined with iris hooks in phacoemulsification of traumatic cataract with lens subluxation / 国际眼科杂志(Guoji Yanke Zazhi)

AlM: To evaluate the clinical efficacy and safety of capsular tension ring ( CTR) combined with iris hooks in eyes with large traumatic zonular dialysis or weakness that underwent micro -incision coaxial phacoemulsification with posterior chamber ( PC ) intraocular lens ( lOL) implantation.METHODS: This prospective study was carried on 21 patients ( 21 eyes ) with traumatic cataract and traumaticzonular dialysis (0. 8 in 5 eyes. lOPs were in normal range too. The lOLs in 20 eyes remained the required position to the final follow- up examination except one eye in which the PC lOL was dislocated into vitreous cavity due to a postoperative spontaneity PCR, and in which vitrectomy and lOL suture fixation was performed.CONCLUSlON: ln cases of cataract associated with traumatic zonular dialysis (<180.) , by setting the rational parameters of phacoemulsification, the CTR and iris hooks are found to be efficient in preventing lOL decentration and reducing operation complication. ln our cases, the CTR combined with iris hooks is relatively safe application.
