Application Of Anterior Chamber Infusing Tube In Cataract Extraction Associated With Vitrectomy For Intraocula Foreign Body

Objective To evaluate the clinical effects of anterior chamber maintainer to exchange infusing tube on sclera incision in cataract extraction associated with vitrectomy for intraocular foreign body.Methods experimental group: To the 30 patients (30 eyes) of intraocular foreign body and traumatic cataract. We used the anterior chamber maintainer and performed extracapsular cataract extraction and vitrectomy. In this process, only 2 sclera incisions are working. Control group: To the 26 patients (27 eyes) of intraocular foreign body and traumatic cataract, we used the classical three sclerotomy site pars plana approach and performed pars plana vitrectomy after extracapsular cataract extraction. In this process, all sclera incisions are working. IOFB was removed by forceps or intraocular. To control intraocular hemorrhage, we applied endodiathermy.Diode endophotocoagulation or transscleral cryotherapy was performed, when indicated. We record the preoperative and postoperative complications. e.g. The circumstance of removing IOFB and visual function after the operation, IOP and complication of corneal, humor vitreous and retinal.Results The study group consisted of 51 (91.07%) male and 5(8.93%) female patients. Their age ranged from 6 to 60 years. IOFB was removed for experimental group and Control group in 28 cases (93.33%) and 25 cases (92.59%), respectively, which indicates insignificant difference (P>0.05). 7 days after operation, the records, with 6 months follow-up on the visual functionality for both two groups, did not show significant difference (P>0.05). While the comparison on high intraocular between two groups revealed obvious difference (P<0.05), where there were 10 cases in the control group with percentage 37.04% and 4 cases in the experimental group with percentage 13.33%. After cure, this difference turned out to be insignificant (P>0.05) based on the observation within 6 months, which also indicates insignificant difference on both the preoperative and postoperative complications between two groups.Conclusions The difference in clinical effects between under anterior chamber maintainer and under infusing tube on sclera incision was insignificant in the clinical effects. Through the anterior chamber maintainer, the B.S.S from the anterior part to the posterior part of the eyeball, is smooth, which ensures the safety and increases the feasibility of associated surgery. Meanwhile, the ACM requires one less sclera incision, which reduces the factor of complications and further simplify the operation and increases the ratio of success. All the experimental results indicate that the anterior chamber infusing tube can take the place of infusing tube on sclera incision in cataract extraction associated with vitrectomy for IOFB...
