Introduction
After vitrectomy, most patients experience a gradual improvement in vision over 1 to 3 months, although the exact duration depends on the extent of surgery, the underlying retinal condition, and individual healing capacity. Clinically, the recovery process is divided into three phases. The first phase occurs from 1 to 14 days post-surgery, during which vision is often blurry and accompanied by a floating sensation due to the unfixed vitreous cavity tamponade material and mild retinal edema.
After vitrectomy, most patients experience a gradual improvement in vision within 1 to 3 months, although the exact duration depends on the extent of surgery, the underlying retinal condition, and individual healing capacity.
Clinical observations divide the recovery process into three phases. The first phase lasts from 1 to 14 days post-surgery; during this time, the vitreous cavity filling material has not yet stabilized and mild retinal edema may occur, often causing blurred vision and a sensation of floating objects. The second phase continues up to approximately week 6, as the tamponade agent adheres to the retina and edema subsides, allowing basic visual function to begin emerging. The third phase spans weeks 6 to 12, during which refractive status stabilizes and most patients achieve their best-corrected visual acuity. However, in cases complicated by diabetic retinopathy or prior retinal detachment, stabilization may take longer—up to 3 to 6 months.
To promote healing and reduce complications, patients should follow these key guidelines: avoid running, jumping, eye rubbing, and high-altitude work to prevent displacement of the intraocular tamponade; wear a rigid eye shield at night and avoid sleeping in a prone position; use antibiotic and steroid eye drops strictly as prescribed—do not adjust steroid dosage independently; undergo fundus photography and OCT scans at follow-up visits to confirm proper retinal reattachment. Immediate medical evaluation is required if sudden vision loss, visual field defects, or flashes of light occur.
In daily life, consume dark green vegetables and fruits rich in lutein, while limiting high-sugar and high-fat foods. After reading for 20 minutes, look into the distance to relax the ciliary muscle, and maintain soft, even indoor lighting. Swimming, diving, and vigorous ball sports should be avoided for 3 months. Prior to air travel, an ophthalmologist must evaluate intraocular pressure and the absorption status of any intraocular gas bubble.
