2Ankara Numune Eğitim ve Araştırma Hastanesi, 3. Göz Kliniği Şef Yard., Ankara Purpose: To investigate the clinical features, visual acuity outcomes and the surgical technique of lens or lens fragments removal peroperatuar and postoperatuar complications for retained lens or lens fragments due to different etiologies.
Materials and Methods: Sixtyfive eyes were included in this retrospective study. Lens fragments were removed from the vitreous by using vitrectomy cutting/aspiration probe alone in 23 eyes and in 21 eyes the lens/fragments were delivered via limbus. Intravitreal phacoemulsification technique was preferred for the removal of hard nucleus or nucleus fragments in 21 eyes. Patients were divided into three groups according to time interval between lens drop and PPV. First group consisted of the ones treated immediately at the same operation session. The second one within 15 days of lens or lens fragment drop.The third one was the ones surgically treated 15 days after the lens or lens fragment drop.
Results: Out 65 patients 41(%63) were male and 24(%37) were female. The age of the patients varied between 14 and 88 years(mean age 60.5 years), and the follow up period varied between 1-24months (mean 12 months). 22 patients which had insufficient follow up records were not included in the prognostic evaluation studies, so assesments were based on 43 patients with sufficient follow up medical records. in 5 of 43 patients intraocular pressure rised over 21 mmHg.In 4 of this 5 patients surgical intervention were performed later than 15 days than lens luxation. The most common common cause of decreased final vision was cystoid macular edema which developed in 4 patients.
Conclusion: There is no correlation between timing of vitrectomy and final visual outcome in patients with intravitreal lens fragments managed surgically. Delayed vitrectomy increases the risk of increased intraocular pressure.
