Purpose: Demonstrate the possibilities of successful surgical treatment of patients with late complications after filtering surgery. Methods: This study shows patients who have developed a cystically dilated or leaking filtering bleb in the late post‐surgical period after filtering surgery. Excision of the indadequate filtering bleb has been performed in the patient with a cystic bleb. After the failure of less invasive methods of treatment, we have proceeded to bleb revision with a scleral patch graft in the patient with a leaking bleb. Results: Patients treated with either bleb excision or scleral patch graft showed no signs of neither hypotonia nor secretion during the six‐months post‐surgical period. During that period, complicated cataracts developed. After cataract surgery the function of the filtering bleb was preserved. Conclusions: During the several months of patients' follow‐up, reconstructive methods of treatment have shown to be successful in high‐risk patients who have developed post‐surgical complications in the form of leaking or inadequate filtering bleb.

Purpose: To determine the incidence of unwanted light images after cataract surgery and the relationship between various intraocular lens (IOL) types. Methods: Prospective study included 50 patients who filled up a written questionnaire where reported on incidence of glare, light sensitivity and unwanted images. Patients were included in the study only if they had uneventful cataract surgery and no additional ocular pathology. They were excluded if they had refractive errors which could cause similar phenomena. The study was performed in three month postoperative period. Results: A significant number of patients reported symptoms. Patients with acrylic IOL were at increased risk. At last control more than 1/3 of symptoms resolved spontaneously. No one reported negative dysphotopsia and there was no IOL exchange. Conclusions: Intraocular lenses can introduce stray light artifacts into the eye. While positive dysphotopsia has been largely attributed to edge effects of the implant, negative dysphotopsia appears to be more related to the patient's anatomical structure than to specific lens designs or materials.
