ABSTRACT
@#AIM:To investigate the effect of small incision non-phacoemulsification cataract surgery on corneal endothelial cell.METHODS:Totally 140 cataract patients (152 eyes) treated in our hospital from August 2013 to March 2016 were selected.All of the patients underwent small incision non-phacoemulsification cataract surgery.Before surgery and at 1wk, 1mo and 3mo after surgery, we measured the corneal endothelium of upper cornea, the central cornea and the lower part of cornea.The proportion and density of hexagonal cells, loss rate and cell area in corneal endothelial cells were calculated and compared.RESULTS:Postoperatively 36 eyes had posterior elastic layer folds, aqueous flare, which disappeared after treatment.After surgery, corneal incision was found to have mild corneal edema.No other complications were found.A total of 128 patients (137 eyes) were followed up for a total of up to 3mo, with a loss of follow-up in 12 patients (15 eyes).After surgery, corneal endothelial cell density of the upper part of the cornea, the central cornea and the lower part of cornea, was statistically significantly different with each other (F=3.526, P=0.031), the difference in different time points was statistically significant (F=4.111, P=0.018).The postoperative corneal endothelial cell loss rate was statistically significant different between the three groups (F=3.526, P=0.031), at different time pionts (F=4.111, P=0.018).There was statistical significance of percentage of hexagonal cells between the three groups (F=4.348, P=0.014), the difference was significantly different between different time points (F=4.964, P=0.008).There was statistical significance of corneal endothelial cell area between the three groups (F=3.180, P=0.044), the difference was significantly different between the time points (F=3.511, P=0.032).CONCLUSION:After small incision non-phacoemulsification cataract surgery, corneal endothelial cell density decreased, hexagonal cell proportion decreased, corneal cell area expanded.
ABSTRACT
AIM:To analyze clinical curative effect of small incision non - phacoemulsification cataract extraction and intraocular lens implantation in the treatment of the high myopia with cataract. METHODS:Seven-four cases (78 eyes) of patients with high myopia and cataract were randomly divided into control group and observation group, 37 cases (39 eyes) in each group. The control group underwent cataract phacoemulsification and intraocular lens implantation, the observation group received small incision non -phacoemulsification cataract extraction and intraocular lens implantation. The treatment effect was analyzed. RESULTS: After treatment, there was no significant difference in the ratio uncorrected visual acuity of 0. 5 and above in two groups. IOP was significantly decreased in two groups after treatment with no significant difference. Intraoperative and postoperative complications in observation group were significantly lower than that in control group. Wound healing time of observation group was significantly shorter than that of the control group.CONCLUSION:Small incision non-phacoemulsification cataract extraction and intraocular lens implantation in the treatment of high myopia with cataract has significant effect, lower complication rate, and is worthy of promotion in clinical.
ABSTRACT
AIM:To analyze the cause of posterior capsular rupture in small incision non - phacoemulsification cataract surgery and investigate the treatment methods. METHODS: The clinical data of 108 cases ( 121 eyes ) undergone small incision non - phacoemulsification cataract surgery combined with intraocular lenses ( IOL) implantation were retrospectively analyzed. The causes of posterior capsular rupture and treatment of 6 patients (6 eyes) after surgery were analyzed and summarized. RESULTS: Six cases ( 6 eyes, 4. 96%) occurred posterior capsular rupture during the operation, of which 2 cases ( 2 eyes ) underwent posterior chamber IOL implantation intraoperative, 2 cases (2 eyes) receivedIIstage IOL implantation in the ciliary sulcus at 1wk postoperative, 2 cases ( 2 eyes ) were given anterior chamber IOL implantation. One case ( 1 eye ) whose vision acuity CONCLUSION:Posterior capsular rupture which occurs in different stages of the operation is the commonest intraoperative complication in small lincision non -phacoemulsification cataract surgery. With improving operative techniques, and continuously accumulating experience, incidence of posterior capsular rupture can be effectively reduced. Even posterior capsular rupture occurs intraoperative, patients can still get a good outcome after timely and proper treatment.
ABSTRACT
AIM: To contrast the effect of small incision phacoemulsification and non-phacoemulsification to treat cataract. METHODS: Totally 172 patients with cataract were divided into 2 groups ( n = 86 ) randomly. Patients in Group Phaco were treated with phacoemulsification and, while those in Group Siecs were treated with small incision extracapsular cataract surgery and intraocular lens implantation. They were all followed up for 1-3y. Functional examinations were made at 3d;1,6mo and last follow - up. The visual acuity, intraocular pressure, anterior chamber depth, average corneal power ( ACP ) , cylinder ( CYL ) , surface asymmetry index ( SAI ) and complications were contrasted between groups. RESULTS: At 3d after operation, the visual acuity of Group Phaco was better than that of Group Siecs ( P 0. 05 ). Furthermore, the APC and anterior chamber depth of each point- in - time had no significant difference between groups (P>0. 05). The incidences of complication were similar in two groups ( P> 0. 05 ); but with individual differences, patients of GradeII and Ⅲ in Group Phaco got lower complication rate (PCONCLUSION: Our research shows that phacoemulsification has high effect in the treatment of patients with GradeII and Ⅲ nuclear hardness, while small incision extracapsular cataract surgery has high effect in the treatment of patients with Grade Ⅳ nuclear hardness.
ABSTRACT
Objective To evaluate the clinical effects and complications of non - phacoemulsification small incision extracapsular cataract extraction(ECCE) and intraocular lens implantation to treat cataract. Methods Through 5.5 -7mm scleral tunnel incisions at 12:00, 212 cases (231 eyes) of cataracts were treated with intraocular lens implantation after continuous circular capsulorhexis and extraction of lens nucleus. Results One week postoperatively, the visual acuity was ≥0.5 in 184 eyes(79.65% ) ; one month postoperatively, the visual acuity was ≥0.5 in 202 eyes(87.45% ). The main complications were corneal edema, anterior chamber inflammation and posterior capsular rupture etc. Conclusion Nnon - phacoemulsification small incision ECCE and intraocular lens implantation is simple and has satisfied effects to treat cataract.
