1/4. Traumatic wound dehiscence following cataract surgery: a thing of the past?PURPOSE: This study compares the frequencies of traumatic wound dehiscence following extracapsular cataract extraction (ECCE) and following phacoemulsification through a self-sealing corneoscleral tunnel. methods: A retrospective review was performed of the surgical record at a British eye hospital from September 1986 to August 1993 and January 1996 to December 1998. Cases requiring surgical repair of wound dehiscence following cataract extraction were identified. The frequencies of traumatic wound dehiscence following ECCE and phacoemulsification were compared using a two by two contingency table (chi-square test). RESULTS: Twenty-one cases of traumatic wound dehiscence were identified following 5,600 ECCEs (0.4%). In 4,200 phacoemulsification procedures only one case of traumatic wound dehiscence was identified (0.02%) (p = 0.0006, OR 15.8, chi2 = 11.69). CONCLUSION: phacoemulsification through a self-sealing corneoscleral tunnel is associated with significantly less risk of traumatic wound dehiscence than is extracapsular cataract extraction. The case of wound rupture following phacoemulsification is discussed with reference to a mechanism for the injury.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/4. Posterior chamber intraocular lenses after extracapsular cataract extraction in patients with aniridia.Visual rehabilitation of patients with aniridia and progressive cataract is a challenging clinical problem. Reduced corneal transparency, limitations of iris support, and decreased zonular integrity may make extracapsular cataract surgery difficult. Four patients with familial aniridia had substantial visual improvement after successful extracapsular cataract extraction (ECCE) with implantation of capsular-fixated posterior chamber intraocular lenses (PC IOLs). In one patient, it was combined with trabeculectomy to treat chronic open-angle glaucoma. Posterior chamber IOLs can be safely implanted in the aniridic eye normalities in the anterior segment.- - - - - - - - - - ranking = 1.6666666666667keywords = extraction (Clic here for more details about this article) |
3/4. Frosted-iris intraocular lens for traumatic aniridia with cataract.We describe an eye with traumatic cataract and aniridia in which we implanted a frosted-iris intraocular lens following endocapsular cataract extraction. The lens was well tolerated and the cosmetic result acceptable.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
4/4. Lateral tarsorrhaphy and disposable soft contact lenses in aniridia patients after penetrating keratoplasty.We report our experience with two patients with familial aniridia who underwent combined cataract extraction and penetrating keratoplasty. Persistent epithelial defects developed in all four eyes within 4 months. Combined lateral tarsorrhaphy and application of disposable soft contact lenses restored the integrity of the corneal epithelium, and 21 months after surgery, the grafts were clear and avascular.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
