METHODS: Electronic medical records of cataractsurgery patients (single surgeon) were reviewed fromJanuary 2018 to September 2021. The rate of postoperativecomplications including prolonged and/or recurrentpostoperative inflammation, endophthalmitis, cystoid macularedema (CME), and intraocular pressure (IOP) was comparedbetween the patients receiving combinative therapy andpatients receiving drops only. RESULTS: Totally 596 patients and 1057 eyes(Combinative-Therapy group 493 and Drop-Only group 564)were included in this study. Using combination therapyreduced the relative risk of postoperative inflammationby 26.9% (16.6% Combinative-Therapy vs 22.7% Drop-Only, P=0.013). The incidence of endophthalmitis was 0in Combinative-Therapy group vs 0.5% in Drop-Only group(relative risk reduction 100%), although not statisticallysignificant (P=0.10). The incidence of severe IOP spikeswas not significantly different between Combinative-Therapy (2.4%) and Drop-Only (1.6%) groups (P=0.33).The relative risk of postoperative CME was 51.4% less inthree months follow up visit in Combinative-Therapy group,although not statistically significant (P=0.07). The visualoutcome 1-month postop. (best corrected visual acuity) wassignificantly better in Combinative-Therapy (logMAR 0.10)compared to Drop-Only (logMAR 0.14) groups (P=0.02) whilethe baseline visual acuity was not significantly different. CONCLUSION: The combinative approach oftranszonular triamcinolone-moxifloxacin plus perioperativeeyedrops is an effective method to minimize postoperativeinflammation, with better visual outcomes. It couldpotentially reduce the risk of postoperative endophthalmitisand CME (near-significant P-values;larger studies couldanalyze better considering low incidence).展开更多

Group 1 included 50 diabetic patients with senile cataract(50 eyes, 30 females, 20 males, aged 55±7 y) received nepafenac 0.1% eye drop. Group 2 included another 50 diabetic patients with senile cataract(50 eyes, 22 female, 28 males, aged 53.8±8 y) did not receive nepafenac. All patients were followed up for 3 mo postoperatively. OCT and MF-ERG were done preoperative and at 1 wk, 1, 2 and 3 mo.RESULTS: The mean foveal thickness was statistically significantly lower in Group 1. Five eyes in Group 2 developed clinical cystoid macular oedema(CMO)(10%), and no patients in Group 1 developed central macular thickening more than 50 μm. There were insignificant differences in MF-ERG amplitudes and latencies between the two groups except in the five eyes that developed CMO, there statistically significant reduction of MF-ERG amplitude with increase in foveal thickness. CONCLUSION: Perioperative nepafenac reduces the incidence of CMO following uncomplicated phacoemulsification significantly. Nepafenac has no side effects.展开更多

Although progress in this technique has greatly reduced surgery-related complications, visual acuity can be substantially compromised in certain circumstances, postoperatively. Cystoid macular edema （CME） is one of the most common complications and needs special attention.展开更多
