title: Phacoemulsification following treatment of choroidal melanoma.
abstract: BACKGROUND
  Little is known about the risks, effects and results of phacoemulsification following treatment with different modalities of choroidal melanoma.
  
  
  METHODS
  In a retrospective study, records were evaluated of 72 patients who underwent cataract surgery after treatment of choroidal melanoma (35 were treated with iodine-125 plaques, 27 with ruthenium-106 plaques, eight by tumor excision, and two with proton beam irradiation). The data were analyzed with respect to complications, effects on postoperative tumor care and visual outcome.
  
  
  RESULTS
  Phacoemulsification was performed at a mean interval of 21.5 months after primary tumor therapy. An intraocular lens (IOL) was implanted in 93% of the cases. The mean postoperative follow-up time was 16.2 months. Preoperative problems were rubeosis iridis (30.5%), secondary glaucoma (34.7%) and posterior synechiae (41.6%). Intraoperatively, defects of the posterior capsule occurred in 12.5%. Visual acuity equal to or better than preoperative vision was found in 95.8% of the patients as the best postoperative measurement and in 72.2% at the last follow-up measurement. A deterioration of more than two lines in visual acuity was observed in 4.2% as the best postoperative vision and in 27.8% at the last documented examination. Phacoemulsification was not the cause of deterioration in any of the cases. After cataract surgery, tumor retreatment was necessary in 19.4%. Treatment of radiation retinopathy was performed for the first time in 13.8%. Metastases developed in six patients (8.3%).
  
  
  CONCLUSIONS
  Phacoemulsification following treatment for choroidal melanoma is both possible and advisable. The majority of patients have enhanced visual acuity. No decrease of vision occurred as a result of cataract extraction. The postoperative care of intraocular tumors and the treatment of radiation retinopathy is improved by timely cataract surgery.
