Additionally, the lens was experimentally reimplanted into the anterior chambers of 3 human cadaver eyes. After fixation of the eyes (Karnovsky's solution), the anterior-posterior length, the white-to-white diameter, the angle-to-angle diameter, and the sulcus-to-sulcus diameter were measured. Two different techniques to cut the eyes were used: sagittal section and corneal buttonhole technique. The plate-haptic silicone lens was then implanted in the anterior chamber and sulcus ciliaris of the eyes. A Kelman multiflex IOL was used as a control for anterior chamber implantation.</p><p><strong>Results: </strong>This experiment demonstrated that the plate-haptic silicone IOL lens is too small and thick for implantation in the anterior chamber and in the sulcus. The lens could easily rotate in the anterior chamber and also dislocate inferiorly, obstructing the visual axis by its edge. The thickness of the lens theoretically could also cause endothelial cell damage and mechanical iris irritation resulting in chronic uveal inflammation.</p><p><strong>Conclusion: </strong>This case and experiment should help surgeons realize the risk and potential for IOL-missizing complications that may be caused if a lens design for the capsular bag is implanted in the anterior chamber, especially if a plate-haptic PC-IOL design is used.</p>","PeriodicalId":19509,"journal":{"name":"Ophthalmic surgery and lasers","volume":"33 6","pages":"480-7"},"PeriodicalIF":0.0,"publicationDate":"2002-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22126817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgical partial excision of the bleb was performed and the tissue was subjected to histopathological evaluation. The bleb area was covered by a conjunctival flap that was advanced with the help of a relaxing incision in the superior conjunctiva fornix. The dissecting bleb was successfully managed by controlling intraocular pressure, and the patient became asymptomatic without any medication. The light microscopic examination of the bleb showed irregularly arranged collagen bundles and hypocellularity of the subconjunctival tissue with places of nodular configuration of the fibroblast in the periphery. Surgical partial excision of the dissecting glaucoma filtering bleb is a reliable, simple, and precise method. Advancing the conjunctival flap by a superior conjunctival relaxing incision facilitates easy mobilization of the flap, ensures healthy resurfacing of the bleb, and prevents postoperative transconjunctival leakage. Histopathology of the bleb is compatible with the use of MMC during original filtering surgery.","PeriodicalId":19509,"journal":{"name":"Ophthalmic surgery and lasers","volume":"282 1","pages":"497-500"},"PeriodicalIF":0.0,"publicationDate":"2002-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80181787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three types of IOLS, acrylic, silicone, and polymethylmethacrylate (PMMA) were allocated to 30 eyes and clinically evaluated. Patients were observed for 3 years postoperatively using an anterior eye segment image analyzer (EAS1000). Opacity was determined by calculating the area of opacity from a retroillumination image. In the retroillumination mode of analysis, the measurement was limited to a 4-mm-diameter region of the pupillary zone to eliminate the influence of anterior capsular opacity.
