Comparison of combined cataract and glaucoma surgery using planned extracapsular and phacoemulsification techniques

Ophthalmic Surg Lasers. 1995 Sep-Oct;26(5):414-9.


Background and objective: The surgical management of coexisting cataract and glaucoma is a common problem for the ophthalmologist.

Patients and methods: We evaluated intraocular pressure (IOP) reduction and bleb formation in combined cataract and filtration surgery, comparing planned extracapsular cataract extraction (ECCE) and phacoemulsification approaches coupled with similar trabeculectomy techniques. Seventy-two eyes with primary open-angle or pseudoexfoliation glaucoma underwent combined cataract and filtration surgery. Thirty-five eyes underwent planned ECCE, intraocular lens (IOL) implantation, and trabeculectomy, and 37 eyes underwent phacoemulsification, IOL implantation and trabeculectomy. Minimum follow-up for both groups was 1 year with a mean of 16 months.

Results: The mean IOP reduction for phacoemulsification/trabeculectomy eyes (5.0 +/- 4.3 mm Hg) was significantly lower than the mean IOP reduction for ECCE/trabeculectomy eyes (2.9 +/- 4.1 mm Hg; P < 0.03). There was no significant difference between the groups in terms of visual acuity improvement or glaucoma medication reduction.

Conclusion: Combined cataract and filtration surgery using phacoemulsification is associated with greater IOP reduction than combined surgery using ECCE.
