ABSTRACT
@#AIM: To evaluate efficacy, safety and complications of 25G vitrectomy, phacoemulsification combined with intrascleral fixated intraocular lens(IOL)implantation for treatment of lens luxation.<p>METHODS: Totally 20 patients(20 eyes)with complete lens luxation and the hardness of lens nucleus was grade 3 or above who underwent 25G vitrectomy, phacoemulsification combined with intrascleral fixated IOL implantation between May 2018 and December 2020 were analyzed retrospectively. The uncorrected visual acuity, best corrected visual acuity, intraocular pressure, the count of corneal endothelium cell, central corneal thickness and complications were observed. <p>RESULTS: The uncorrected visual acuity and best corrected visual acuity after operation were improved than those before treatment(<i>P</i><0.05). The number of corneal endothelial cells in the central part of cornea after operation was lower than that before operation(<i>P</i> >0.05). There was no significant difference in central corneal thickness 2wk after operation compared with that before operation(<i>P</i> >0.05). There were 3 cases of low intraocular pressure and 2 cases of high intraocular pressure, but they all returned to normal at the end of follow-up. The IOL were all centered and there were no obvious eccentricity and inclination. No other complications such as vitreous hemorrhage and retinal detachment occurred.<p>CONCLUSION: 25G vitrectomy, phacoemulsification combined with intrascleral fixated IOL implantation is a fast, safe and simple method for the treatment of complete lens luxation.
ABSTRACT
AIM:To compare the clinical effect of 23G and 25G+ vitrectomy for treatment of proliferative diabetic retinopathy (PDR).METHODS: A total of 128 PDR patients (195 eyes) requiring vitrectomy in our hospital from November 2013 to May 2016 were randomly divided into 25G+ group and 23G group, 64 cases (97 eyes) in 25G+ group and 64 cases (98 eyes) in 23G group.In 25G+ group, patients were treated by 25G+ vitrectomy.In 23G group, patients were treated by 23G vitrectomy.The visual acuity, as well as intraocular pressure (IOP), iatrogenic injury and complications in two groups were recorded before and 1d, 1wk, 1mo after treatment.The operation time was compared between two groups.RESULTS: The operation time in 25G+ group was lower than that in 23G group (P0.05).IOP in 25G+ group before surgery had no significant difference compared with those after surgery at 1d,1wk, and 1mo(P>0.05), which it was the same in 23G group.IOP of two groups in the same period had no significant difference (P>0.05).The incidence rate of iatrogenic injury in 25G+ group was 4.1%, which was significant lower than that of 23G group (13.3%) (P<0.05).The incidence rate of complication in 25G+ group was 3.1%, which was significant lower than that of 23G group (11.2%) (P<0.05).CONCLUSION: Both 23G and 25G+ vitrectomy are safe and effective treatment for PDR.However, 25G+ vitrectomy is the better choice for PDR for the shorter operation time, lower incidence rate of iatrogenic injury and fewer surgical complications.
ABSTRACT
?AIM: To observe the efficacy of 25G vitrectomy for traumatic cataract.?METHODS:Retrospective analysis of 70 cases (70 eyes) of traumatic cataract treated by 25G vitrectomy with lensectomy from February 2013 to February 2015 in our hospital was made for the study.In the patients, there were 43 males ( 43 eyes ) , 27 females ( 27 eyes ) , aged from 22-51 years old with an average of 35.23±2.54 years, mean visual acuity was 0.10±0.03.They were all followed up for 6 -12mo postoperatively. Anterior segment, fundus, complications, best corrected visual acuity ( BCVA ) and intraocular pressure were observed during the follow - up. BCVA preoperatively, 1wk postoperatively, 1 mo postoperatively, 6mo postoperatively were compared.? RESULTS: All the patients underwent the surgery successfully, and visual acuity improved at different degrees. The differences of BCVA preoperatively compared with 1 and 6m postoperatively were all statistically significant ( P <0. 05 ). Postoperative complications:5 cases with corneal edema, 10 cases with ocular hypertension, 4 cases with ocular hypotension, 5 cases with retinal spotting.The symptoms improved after symptomatic and supportive treatment.? CONCLUSION: 25G vitrectomy with lensectomy is effective on treating traumatic cataract, with decreased operation risk, complications and improved visual acuity.
