Combined cyclodialysis and cataract extraction.
Combined cyclodialysis and cataract extraction was performed on 78 eyes in a consecutive series of 26 years duration. This operation was performed on eyes with severe glaucoma, inadequately controlled on maximum medical therapy, and with a cataract needing extraction. Glaucoma types included open-angle, angle-closure with peripheral anterior synechias, combined open-angle and angle-closure, and secondary to uveitis. Seventy of the 78 eyes had follow-up of six months or more and the results in these 70 eyes were analyzed. In thirteen percent of the eyes in this study the postoperative intraocular pressure was the same or higher than the preoperative level, or reductions of intraocular pressure were not clinically significant. Eighty-seven percent (61 eyes) had a clinically significant lowering of intraocular pressure following the combined procedure. Thirty-nine percent (27 eyes) of the 70 eyes in this study had a tension of 0-14 mm Hg, and 44% (31 eyes) had a tension of 15-20 mm Hg. Intraocular pressure was improved significantly more often in patients over 60 years of age. Resulting intraocular pressures of 14 mm Hg or less were more likely when the cyclodialysis was performed in the lower quadrant. The results of the combined procedure were not significantly influenced by the type of glaucoma involved or by a history of previous glaucoma surgery. Bleeding was a frequent complication, but was not related to resulting intraocular pressure. Other complications were rare. We conclude that combining cyclodialysis with cataract extraction is safe and effective, and is a suitable procedure when there is need for surgery to relieve severe glaucoma, along with a need for cataract extraction.
