“…Difficulties with nucleus expression extracapsular cataract extraction have been reported in the vitrectomised eye, and have been presumed to be caused by the loss of vitreous counter pressure. 5,6 With phacoemulsification, abnormal variations in the anterior chamber depth, unstable zonules, and posterior capsules have also been described. McDermott et al 7 reported on 22 eyes that had vitrectomy for proliferative diabetic retinopathy, retinal detachment, macular holes, and epiretinal membranes.…”

“…[2][3][4] Cataract surgery in the vitrectomised eye has been reported to present special challenges, which include the loss of vitreous support, unstable posterior capsules, weakened zonules, and posterior capsular plaques. [5][6][7][8] In this study, we examine the intraoperative characteristics of phacoemulsification in the vitrectomised eye, associated complications, and evaluate the visual outcomes.…”

Aims To examine the intraoperative characteristics of phacoemulsification in eyes that had undergone pars plana vitrectomy and to determine complication rates and visual outcomes. Methods A prospective study of 45 consecutive cataract operations on vitrectomised eyes performed over a 9-month period by a single surgeon. Data were collected on preoperative characteristics, intraoperative observations and complications, postoperative complications, and visual acuities.

Aims To determine the intraoperative and postoperative complications and visual outcome of eyes undergoing cataract extraction after previous retinal detachment repair by pars plana vitrectomy (PPV). Methods Retrospective analysis of 72 patients who had cataract extraction by phacoemulsification having had retinal detachment repair by vitrectomy and internal tamponade. Results Best-corrected visual acuity (BCVA) had improved in 53 (74%) of eyes at 3 weeks after cataract surgery and 65 (90%) at final follow-up. Fifty-three eyes (74%) attained 6/12 visual acuity at final follow-up compared with 19 (26%) eyes with a preoperative vision better than 6/12. There was a significant improvement in BCVA after cataract extraction (Po0.001). Poor vision was usually related to retinal comorbidity. Intraoperative events occurred in nine eyes (12.5%) including capsulorrhexis tears, zonular dehiscence and vitreous loss. Postoperative events occurred in 15 eyes (20.8%). Retinal re-detachment occurred in four eyes (5.6%). Conclusions Cataract extraction after retinal detachment surgery by vitrectomy generally results in a significant visual improvement, however, there is an increased intraoperative and postoperative complication rate. The risk of retinal re-detachment may previously have been underestimated.

“…Cerca de 51% a 88% dos olhos desenvolvem catarata no pós-operatório. Isto faz com que o procedimento combinado exija estudo acurado como uma técnica alternativa para aqueles pacientes com retinopatia diabética proliferativa, fácicos, com esclerose do cristalino e que precisam de vitrectomia via pars plana (13,(15)(16) .…”

Facoemulsificação, vitrectomia via pars plana e implante de lente intra-ocular em olhos com retinopatia diabética proliferativa Objetivo: Avaliar a viabilidade da técnica de facoemulsificação para a extração da catarata com implante de lente intra-ocular combinada à vitrectomia via pars plana em olhos com retinopatia diabética proliferativa, em um único procedimento cirúrgico. Métodos: Foram revisados os prontuários de 47 pacientes (53 olhos) com retinopatia diabética proliferativa e catarata que foram submetidos ao procedimento combinado de vitrectomia via pars plana, facoemulsificação e implante de lente intra-ocular no mesmo ato cirúrgico, entre janeiro de 1991 e setembro de 1998 no Bascom Palmer Eye Institute, hospital de olhos filiado à Universidade de Miami. O estudo foi realizado em conjunto com a Universidade Federal de São Paulo. Participaram do estudo 43 olhos de 40 pacientes. Resultados: O tempo de seguimento variou de três a 60 meses com média de 20 meses. A idade dos pacientes variou de 37 a 77 anos com média de 59 anos. A acuidade visual melhorou duas linhas ou mais em relação ao pré-operatório em 26 (60,4%) olhos, permaneceu a mesma em 9 (20,9%) e piorou em 8 (18,6%). Em (23,2%) 10 olhos a acuidade visual aumentou para 20/40. O teste estatístico chamado de "teste do sinal" mostrou-se estatisticamente significante na melhora da acuidade visual final. A complicação mais observada foi a hemorragia vítrea recorrente, ocorrendo em 12 (27,9%) olhos, seguida pela inflamação transitória da câmara anterior em 9 olhos (20,9%). Complicações intra-operatórias relacionadas à extração do cristalino foram raras. No pós-operatório observaram-se captura da lente intraocular em 2 (4,6 %) olhos e lente intra-ocular subluxada em 1 (2,3%) olho. Conclusões: A cirurgia combinada de facoemulsificação, implante de lente intra-ocular e vitrectomia via pars plana em olhos com retinopatia diabé-tica é procedimento bem tolerado e geralmente apresenta bons resultados com relação à acuidade visual. Um único procedimento para remover a catarata e realizar a vitrectomia via pars plana, ao invés de se realizar uma segunda cirurgia, que seria somente para a remoção da catarata após a vitrectomia pars plana, é técnica segura e capaz de promover a melhora da acuidade visual além de ser menos agressiva para o paciente. O potencial para melhora da acuidade visual final é limitado pela gravidade da retinopatia diabética.
