We evaluated the lens fibers and lens thickness in 30 eyes before and after vitreous surgery. The series included proliferative diabetic retinopathy 10 eyes, tractional retinal detachment 9 eyes, central retinal vein occlusion 8 eyes among others. The crystalline lens was clear in all the eyes prior to surgery. We photographed the lens fibers in the anterior cortex using specular microscope and cone lens. The lens thickness was measured by ultrasono-graphy. We observed the width of lens fibers and fiber spaces to increase and to become irregular from the early postoperative stage on. The thick-ness of the lens increased slightly during the post-operative 2 weeks to 3 months. The observed changes in lens morphology seemed to suggest that the barrier in the lens cortex was destroyed by the absence of anterior vitreous after vitreous surgery.
