PURPOSE: To describe the results of surgical treatment for subluxated lens in forty patients (seventy-one eyes) using lensectomy. METHODS: Forty patients with subluxated lens that were submitted to pars plana lensectomy from January 1990 to December 2000 were evaluated regarding systemic diagnosis, related ocular disease, age of patient at surgery, pre and post operative visual acuity and complications related to surgery. Indications for surgery were best corrected visual acuity of 20/70 or less and complications related to dislocated lens. RESULTS: Best corrected visual acuity improved in fifty seven eyes (80,3%), there was no change in visual acuity in four eyes (5,6%) and visual acuity became worse than before in one eye (2.08%). Follow up ranged from 6 to 120 months. Complications occurred in two eyes: one had post-operative retinal detachment and another had intraoperative vitreous hemorrhage. CONCLUSIONS: The results and long-term follow-up for these patients demonstrate that lensectomy as a closed-system for subluxated lens improves visual acuity and seems to be a safe procedure with few complications.3516269Salehpour, O., Lavy, T., Leonard, J., Taylor, D., The surgical management of non traumatic ectopic lens (1996) J Pediatr Ophthalmol Strabismus, 33, pp. 8-13Halpert, M., Ben Ezra, D., Surgery of hereditary subluxated lens in children (1996) Ophthalmology, 103, pp. 681-686Nelson, L.B., Maumenee, I., Ectopia lentis (1982) Surv Ophthalmol, 27, pp. 143-160Blumenthal, M., Kurtz, S., Assia, El., Hydroexpression of subluxated lenses using a glide (1994) Ophthalmic Surg, 25, pp. 34-37Jarret, W.H., Dislocations of the lens: A study of 166 hospitalized cases (1967) Arch Ophthalmol, 78, pp. 289-296Dixon, J., On the treatment of posterior displacement of the lens (1853) Lancet, 2, p. 313Varga, B., The results of my operations improving visual acuity of ectopia lentis (1971) Ophthalmologica, 162, pp. 98-110Maumenee, A.E., Ryan, S.J., Aspiration technique in the management of the dislocated lens (1969) Am J Ophthalmol, 68, pp. 808-811Croll, M., Croll, L.S., Cryoextraction of dislocated lenses (1975) Ann Ophthalmol, 7, pp. 1245-1252Zeeman, W.P.C., Ectopia lentis congenital (1942) Acta Ophthalmol, 20, pp. 1-13Peyman, G.A., Rauchand, M., Goldberg, M.F., Ritacia, D., Management of subluxated and dislocated lenses with the vitriophage (1979) Br J Ophthalmol, 63, pp. 771-778Behki, R., Noel, L.P., Clarke, W.N., Limbal lensectomy in the management of ectopia lentis in children (1990) Arch Ophthalmol, 108, pp. 809-811Seetner, A.A., Crawford, J.S., Surgical correction of lens dislocation in children (1981) Am J Ophthalmol, 91, pp. 106-110Reese, P.D., Weigeist, T.A., Parsplana management of ectopia lentis in children (1987) Arch Ophthalmol, 105, pp. 1202-1204Plager, D.A., Parks, M.M., Helveston, E.M., Ellis, F.D., Surgical treatment for subluxated lenses in children (1992) Ophthalmology, 99, pp. 1018-1023Speedwell, L., Russel-Eggitt, I., Improvement in visual acuity in children with ectopia lentis (1995) J Pediatr Ophthalmol Strabismus, 32, pp. 94-97Friedman, Z., Feiner, M., A simplified technique for extraction of subluxated lenses in young patient (1998) Ophthalmic Surg Lasers, 29, pp. 949-950Hakin, K.N., Jacobs, M., Rosen, P., Taylor, D., Cooling, R.J., Management of subluxated crystalline lens (1992) Ophthalmology, 99, pp. 542-545Dietlein, T.S., Jacobi, P.C., Konen, W., Krieglstein, G.K., Complications of endocapsular tensin ring implantation in a child with Marfan's syndrome (2000) J Cataract Refract Surg, 26, pp. 937-940Syrdalen, P., Pars plana technique for removal of subluxated lenses in young patients (1987) Acta Ophthalmol, 65, pp. 585-588Girard, L.J., Canizales, R., Esnaola, N., Rand, W.J., Subluxated (ectopic) lenses in adults (1990) Ophthalmology, 97, pp. 462-465Yu, Y.S., Kang, Y.H., Lim, K.H., Improvements in visual acuity following limbal lensectomy for subluxated lens (1997) Ophthalmic Surg Lasers, 28, pp. 1006-1010Tsai, Y.Y., Tseng, S.H., Transscleral fixation of foldable intraocular lens after pars plana lensectomy for subluxated lens (1999) J Cataract Refract Surg, 25, pp. 722-724Zetterstrom, C., Lundvall, A., Webber Jr., H., Jeeves, M., Sulcus fixation without capsular support in children (1999) J Cataract Refract Surg, 25, pp. 776-781Kazemi, S., Wirostko, W.J., Sinha, S., Mieler, W.F., Koenig, S.B., Sheth, B.R., Combined pars plana lensectomy-vitrectomy with open loop flexible anterior chamber intraocular lens (AC IOL) implantatiom for subluxated lenses (2000) Trans Am Ophthalmol Soc, 98, pp. 247-251Lam, D.S.C., Young, A.L., Leung, A.T.S., Rao, S.K., Fan, D., Ng, J.S.K., Scleral fixation of a capsular tension ring for severe ectopia lentis (2000) J Catarac Refract Surg, 26, pp. 609-612
