Long-term efficiency of cataract surgery with hydrophilic acrylic Ioflex intraocular lens.

OBJECTIVE: To evaluate the efficiency of long-term cataract surgery using low-cost intraocular lens implantation in community campaigns. METHODS: Fifty-eight randomly selected patients were evaluated four years after phacoemulsification and Ioflex intraocular lens implantation. Causes of low visual acuity related to the intraocular lens were evaluated, and treatment costs were calculated. RESULTS: The mean age of patients was 72±10.2 years. Four years after surgery, 25 eyes (43.0%) had decreased visual acuity related to the intraocular lens: posterior capsule opacification was noted in 24 eyes (41.3%), and intraocular lens opacification was noted in one eye (1.7%). The total cost of the post-surgical complication treatments represented 6.3% of the initial budget of the entire surgical patient group. CONCLUSIONS: The efficiency of cataract surgery with low-cost Ioflex intraocular lens implantation was significantly reduced in a long-term follow-up study because postoperative complications related to intraocular lenses emerged at higher rates than when the gold-standard treatment was used.

Incidence of posterior capsule opacification following the implantation of a foldable hydrophilic acrylic intraocular lens: a 4 year follow-up study.

PURPOSE: To evaluate the incidence of posterior capsule opacification (PCO) four years after the implantation of a hydrophilic acrylic intraocular lens (IOL). METHODS: Fifty-eight randomly selected eyes from 58 patients were analyzed four years after phacoemulsification and Ioflex IOL implantation. The patients underwent an ophthalmic examination to detect PCO and a detailed medical history was obtained. The patients' charts were reviewed for their corrected distance visual acuity prior to the IOL implantation, as well as for one month postoperatively. The Student's t-test was used for statistical analysis. RESULTS: The mean age of patients without PCO was 74.6 ± 9.5 years, compared to 70.3 ± 15 years in patients with PCO. Four years after surgery, 39 of the 58 eyes (67%) had detectable PCO and 24 eyes (41.3%) had decreased visual acuity (VA) due to PCO. These patients were referred for Nd:YAG laser capsulotomy. Three patients (5.1%) had decreased VA due to glaucoma, IOL opacification, or age-related macular degeneration. Twelve eyes (20.7%) presented mild PCO with unchanged VA. Systemic arterial hypertension was reported by 45% of the patients, and in 3.5% of these cases this was associated with diabetes mellitus. CONCLUSION: This study found the incidence of PCO to be 67% four years after phacoemulsification and Ioflex IOL implantation.

Objetivo: Avaliar a incidência da opacificação da cápsula posterior com o implante de uma lente intraocular acrílica hidrofílica. Métodos: Cinquenta e oito olhos, de 58 pacientes, selecionados de forma aleatória, foram examinados 4 anos após a cirurgia de facoemulsificação com implante da lente intraocular Ioflex em uma campanha comunitária para pessoas carentes. Os pacientes foram submetidos ao exame oftalmológico a fim de detectar opacificação da cápsula posterior. Foi obtido histórico médico detalhado. A acuidade visual corrigida antes e 1 mês após a cirurgia foi obtida através de revisão em prontuário médico. O teste t de student foi utilizado para a análise estatística. Resultados: A idade média dos pacientes sem opacificação da cápsula posterior foi 74,6 ± 9,5 anos, e 70,3 ± 15 anos nos pacientes com opacificação da cápsula posterior. Após 4 anos da cirurgia, 39 olhos (67%) foram diagnosticados com opacificação da cápsula posterior, e 24 olhos (41,3%) tiveram redução da acuidade visual causada pela opacificação da cápsula posterior, sendo encaminhados para realização de capsulotomia com Nd:YAG laser. Três olhos (5,1%) tiveram redução da acuidade visual causada por glaucoma, opacificação da lente intraocular e degeneração macular relacionada á idade. Em outros 12 olhos (20,7%) que apresentaram opacificação da cápsula posterior, a acuidade visual ficou mantida. Dentre as doenças sistêmicas, a hipertensão arterial foi relatada por 45% da amostra avaliada e 3,5% referiram diabetes mellitus. Conclusão: O estudo encontrou incidência de 67% de opacificação da cápsula posterior na lente intraocular Ioflex 4 anos ...

Late opacification in hydrophilic acrylic intraocular lenses: analysis of 87 eyes in a random sample of 102 patients.

PURPOSE: To report the incidence of late postoperative opacification of a hydrophilic acrylic foldable intraocular lens (IOL). SETTING: Altino Ventura Foundation, Pernambuco, Brazil. DESIGN: Cross-sectional study. METHODS: Patients were examined 4 years after phacoemulsification with Ioflex IOL implantation in the rural areas of Pernambuco, Brazil, as part of a community campaign for underprivileged people. The patients had a detailed ophthalmic examination to detect late IOL opacification. The patients' charts were reviewed for preexisting ocular pathology and corrected distance visual acuity (CDVA) before and 1 month after surgery. The IOL opacification was classified according to its location and severity. RESULTS: All surgeries were uneventful intraoperatively and postoperatively. Six (7%) of the 87 eyes (58 patients) examined had a diagnosis of late IOL opacification; asteroid hyalosis and high myopia were associated ocular findings in 2 of the eyes. The preoperative CDVA ranged from hand motions (HM) to 20/80. The postoperative CDVA ranged from 20/20 to 20/40 except in 1 eye with posterior segment disease. Over the 4-year follow-up, 2 of the 6 eyes had a decrease in visual acuity to HM and 20/80, respectively, as a result of late IOL opacification. They had IOL replacement and CDVA improved to 20/60 and 20/20, respectively. A third eye with severe late opacification was not referred for IOL replacement because of macular disease. CONCLUSION: Intraocular lens opacification was observed in 7% of the eyes studied. No risk factors could be determined.
