[Comparison between the postoperative results of triple procedure and combined penetrating keratoplasty/transsclerally sutured posterior chamber lens implantation]. / Comparação entre os resultados pós-operatórios de pacientes submetidos ao procedimento tríplice e transplante de córnea combinado a fixação secundária de lente intra-ocular.

PURPOSE: To compare the outcomes of two surgical techniques of penetrating keratoplasty with different surgical time, regarding the crystalline and the intraocular lens. METHODS: This retrospective study included 37 patients' eyes divided into 2 groups: extracapsular cataract extraction, posterior chamber intraocular lens implantation and penetrating keratoplasty (Group 1, G1) and transscleral fixation of posterior chamber lens and penetrating keratoplasty (Group 2, G2). The following parameters were recorded: visual acuity, intraocular pressure, refractive astigmatism, complication and keratometric astigmatism. RESULTS: Visual acuity improved in the two groups (G1 p<0.001 and G2 p=0.008). In G2 a significant change for the worse of intraocular pressure outcome was observed when compared with the other group (p=0.014). Regarding refractive and keratometric astigmatism no significant differences between the groups were found. The follow-up was 11 months. CONCLUSION: The most important negative prognostic factor affecting visual acuity was the postkeratoplasty corneal curvature which can not be predicted accurately and the most important negative factor affecting intraocular pressure was the loss of integrity of the anterior and posterior segments.
