I have developed a simple method of fixating an IOL into the ciliary sulcus which does not require different needles, multiple needle passes, scleral dissection, or awkward surgical maneuvers.Methods: Thirty eyes were enrolled in this study. All eyes were either aphakic, requiring a secondary lens implantation, or required IOL exchange. The patients were followed for 30 months. Using a single 10-0 double-armed, polypropylene suture, a through-and-through infraciliary scleral pass secured each haptic without tying. The lens was then positioned into the ciliary sulcus and the knots tied outside the eye under direct visualization.Results: This procedure has been used in 30 eyes without erosion of sutures, dislocation or tilting of the IOL, or induced astigmatism. Twenty-one eyes (70%) had spectacle-corrected visual acuity of 20/40 or better.Conclusion: The results of this study demonstrate that posterior chamber transscleral fixated IOLs give improved postoperative visual results.","PeriodicalId":79348,"journal":{"name":"Journal of refractive and corneal surgery","volume":"10 6","pages":"647-51"},"PeriodicalIF":0.0,"publicationDate":"1994-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18721663","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}

Although visual acuity is usually impaired and corneal function compromised, there has been only limited success in the clinical management of this condition. We evaluated the efficacy of laser photocoagulation of neovascularization in the rabbit cornea.\u0000\u0000\u0000METHODS\u0000New vessel formation was provoked by the placement of sutures in the corneas. Rose bengal was injected intravenously and new vessels in the upper part of the corneas were treated with an argon laser. The lower halves were used as controls. Eighteen rabbits were divided into 2 groups. In group A neovascularization was treated 28 days after suture removal, when corneal inflammation had regressed. In group B treatment was performed 3 days after suture removal, when the cornea still exhibited marked inflammation. Postoperatively, the corneas were studied by slit-lamp microscopy, fluorescein angiography, and light, as well as electron microscopy.\u0000\u0000\u0000RESULTS\u0000In group A, treatment led to the immediate occlusion of the vessels and to their gradual disappearance during the course of 3 months. In group B, no occlusion was seen during the 3-month follow-up period. The main histologic findings in the occluded vessels were endothelial cell disruption and degeneration, and the formation of clots.\u0000\u0000\u0000CONCLUSION\u0000Our results suggest that argon laser photocoagulation using rose bengal is an effective method of occluding corneal new vessels, providing there is no corneal inflammation at the time of treatment.","PeriodicalId":79348,"journal":{"name":"Journal of refractive and corneal surgery","volume":"10 6 1","pages":"631-9"},"PeriodicalIF":0.0,"publicationDate":"1994-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70145954","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}

Two of the recurrent erosion patients suffered subsequent spontaneous abrasions and one of the traumatic abrasion patients developed a possible infectious keratitis which cleared without visual loss.Conclusions: In this small series, the combination of a disposable soft contact lens and the instillation of diclofenac drops provided significant pain relief while the abrasion healed and allowed the patients to function with binocular vision.
