ABSTRACT
AIM: To compare the efficacy of aflibercept and ranibizumab in the treatment of diabetic macular edema(DME).METHODS: Prospective randomized controlled trial. A total of 35 patients(60 eyes)with non-proliferative diabetic retinopathy complicated with DME confirmed in our hospital from June 2020 to September 2021 were included. Intravitreal injection was performed using the 3+PRN protocol in all cases, of which 17 cases(30 eyes)received aflibercept treatment(aflibercept group)and 18 cases(30 eyes)received ranibizumab(ranibizumab group). The two groups were followed up for 12mo, observing the central macular thickness(CMT)and the best corrected visual acuity(BCVA)of the two groups, and recording the number of intravitreal injections and the occurrence of complications.RESULTS: After treatment, CMT and BCVA in the aflibercept group were significantly better than that in the ranibizumab group at 1, 3, 6 and 12 mo(all P<0.001). During the follow-up period, the number of intravitreal injections in the aflibercept group was lower than that in the ranibizumab group(4.23±0.86 vs. 6.40±0.97, P<0.05), there were no serious complications such as drug-related adverse reactions, intraocular infection, and vascular embolism in either group.CONCLUSION: Both aflibercept and ranibizumab have clear efficacy and safety in the treatment of DME, and aflibercept may be a more effective and convenient treatment option than ranibizumab for DME patients.
ABSTRACT
AIM: To observe the efficacy and safety of small incision manual nuncleofragmentation technology in hard-nucleus cataract.METHODS: Fifty-four patients (54 eyes) were performed with small incision manual nucleofragmentation and intraocular lens implantation.Uncorrected-visual acuity,corrected-visual acuity and astigmatism were measured before and after surgery.Anterior segment of eye,retina,surgical complications were observed.RESULTS: Preoperative uncorrected vision(LogMAR) was 1.095±0.171,corrected vision (LogMAR) was 0.994±0.158.Postoperative uncorrected vision(LogMAR) was 0.321±0.214 and corrected vision(LogMAR) was 0.276±0.179 at 1wk after operation.Both had statistical significance compared with uncorrected vision(LogMAR) (t=27.052,P0.05).No severe complications occurred in all cases.CONCLUSION: The technology of small incision manual nuncleofragmentation in hard-nucleus cataract is proved to be safe and effective.
ABSTRACT
To evaluate the clinical effect of small incision cataract extraction with a manual nucleus division technique combined with intraocular lens implantation in cataract operation of large quantities. ●METHODS: Totally 105 patients (105 eyes) underwent small incision cataract extraction surgery. Visual acuity was observed, eye condition, fundus and intraocular pressure were examined by slit lamp at postoperative 1wk; 1mo. ●RESULTS: The visual acuity improved significantly at postoperative 1mo, 89 cases (89 eyes) with better than 0. 3( 85%), 101 cases ( 101 eyes) with 0. 1 and above (96%). lt had short operation time, fewer complications and good anesthetic effect. ● CONCLUSlON: This operation is suitable for primary hospitals, which visual acuity improved obviously, without serious complications, and economic and feasible.
