The results are summarized as follow: 1. The cryo-extraction have been done for 41 males and 57 females of the 98 patients. 2. The incidences of complication during operation were capsule rupture (5.7%), vitreous loss (4.9%), iris prolapse (1.6%). 3. The incidences of early postoperative complication were hyphema (12.1%). updra wn pupil (8.9%), corneal edema (6.5%), flat anterior chamber (4.9%). 4. The incidences of late postoperative complication were vitreous bulging (5.7%), vitreous opacity (4%), glaucoma(2.4%), uveitis (0.8%), retinal detachment (0.8%). 5. The ccrrected visual acuities before discharge of hospital were: more than 0.5 ... 39.0% (48 eyes), 0.1-0.4 ... 48.8% (60 eyes), less than 0.1 ... 12.2% (15 eyes). 6. The major causes of visual acuity less than 0.1 were vitreous opacity (33.4%), secondary glaucoma (20%), proliferative diabetic retinopathy (20%), corneal opacity (13.4%), retinal degeneration (13.3%).
