Silicone Oil Tamponade Combined with Lensectomy Preserving Anterior Lens Capsule

Purpose: To investigate the therapeutic effect and indication of silicone oil tamponade combined with lensectomy preserving anterior lens capsule. Methods: Silicone oil tamponade combined with lensectomy preserving anterior lens capsule was performed in 33 cases (33 eyes) of high myopia, proliferative vit-roretinopathy (PVR) D grade and giant retinal tear (CRT). 10 cases were only eye and 11 cases had harder nucleus of lens. The surgical methods included: 1. smashing lens nucleus and lensectomy preserving complete anterior capsule; 2. vitrectomy and membrane peeling; 3. usage of liquid perfluorocarbin or retinotomy for drainage; 4. silicone oil tamponade; 5. postoperative Nd; YAG laser for anterior capsulectomy. Results: Follow-up time was 6 months or more in 29 cases. Total retinal reattachment was achieved in 22 cases, macular retinal reattachment in 5 cases. The visual acuity was 20/800 to 20/200 in 13 cases, 20/100 to 20/50 in 12 cases. Visual acuity was significantly improved in GRT group (P < 0. 05) . Complications included unexpected anterior capsule break intraoperatively, anterior capsule opacity, silicone oil emulsifi-cation and liquid perfluorocarbin remaining postoperatively. Conclusions: Silicone oil tamponade combined with lensectomy preserving anterior capsule was safe and can reduce the operative complications. The indications included: 1. GRT complicated with high myopia; 2. advanced PVR cases complicated with high myopia in which silicone oil must be used; 3. severe lens opacity cases in which silicone oil must be used; 4. complex retinal detachment of only eye.
