The Management of Posterior Lens Dislocation

ABSTRACT

From Nov. 1990 to Dec. 1994, authors have experienced 12 patients(13 eyes) diagnosed as posterior lens dislocation. The clinical results were evaluated in aspeets of sex and age distribution, preoperative and postoperative visual acuity, operative method, postoperative complication. The average age of patients was 57.8 years old and average follow-up period was 11.5 months. Male were 58%. They have history of ocular trauma in all 13 eyes. Dislocated lens was removed by extraction with lens spoon or loop through corneoscleral incision in 3 eyes and pars planar vitrectomy followed by lens lift with needle and extraction through corneoscleral incision in 7 eyes or with perfluorocarbon liquid and extraction with spoon or loop in 3 eyes. The best corrected visual acuity was improved in 10 eyes and remained the same in 2 patient(3 eyes) who was visited our hospital more than 10 years after dislocation and associated with optic nerve atrophy, macular degeneration, bullous keratopathy. Postoperative complications included glaucoma, choroidal detachment, retinal detachment, persistent vitreous inflammation, vitreous hemorrhage, bullous keratopathy.
