OBJECTIVE Traditionally, the argon laser has been used with suture lysis. The authors evaluate the krypton laser and define the parameters for the successful use of the laser with this procedure. METHODS Five consecutive patients undergoing combined cataract and trabeculectomy surgery who were considered candidates for this procedure underwent krypton laser suture lysis. Three laser suture lysis contact lenses were used during this procedure. None of the patients underwent adjuvant chemotherapy in the form of either 5-fluorouracil or mitomycin-C. RESULTS All five patients were successfully treated with the krypton laser. In all cases, the 10-0 nylon sutures were cut. No complications were observed in any patients. The only side effect observed was occasional mild pain noted by the first few patients during the procedure. As the krypton laser settings were adjusted, this problem was corrected. CONCLUSIONS The krypton laser can be successfully used to cut 10-0 nylon sutures following trabeculectomy surgery.

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
