Purpose. To conduct a comparative analysis of two groups of patients according to the results of cataract phacoemulsification in combination with the silicone oil removal through flat part of the ciliary body and posterior capsulorhexis in the long term after retinal detachment surgery.Material and methods. 30 patients with a diagnosis of cataract, avitria, tamponade of the vitreous cavity with silicone oil OXANE 5700 were under observation. Patients were randomly divided into two groups. In both groups, the infusion system was installed through port 25 Ga located 3–4 mm from the limb, cataract phacoemulsification was performed in the first stage. In the first group (15 patients), silicon oil was removed through the posterior capsulorexis using a curved aspiration cannula of caliber 18 Ga. In the second group (15 patients) silicon oil was removed using aspiration through the second port of 25 Ga.The assessment of the functional and anatomical state after surgery was based on data from visometry, autorefractometry, ultrasound B-scanning of the vitreous cavity, and optical coherence tomography of the macular area. Assessment of patient satisfaction with the subjective level of quality of life was carried out using the validated visual function questionnaire Visual Function (VF-14).Results. In both groups, on average, there was a significant increase in the best corrected visual acuity. According to B-scan data, emulsified silicone oil particles were less detected in patients after removal of silicone oil through posterior capsulorexis. The subjective level of quality of life of each patient improved significantly in both groups.Conclusion. Performing the combined operation of cataract phacoemulsification with the removal of silicone oil through the posterior capsulorhexis in comparison with the silicone oil removal through the flat part of the ciliary body can equally improve visual function. Satisfaction with treatment results was slightly higher in the group with silicone oil removal through posterior capsulorexis.Key words: cataract, avitria, silicone oil, posterior capsulorexis.
