Purpose:
it is widely accepted that previous ocular surgery may have negative effect on trabeculectomy operation. The purpose of the study is to present the postoperative course of patients (eyes) who underwent trabeculectomy after uncomplicated phacoemulsification with posterior chamber intraocular lens implantation in comparison to eyes undergoing trabeculectomy as the first procedure.
Setting:
Glaucoma Clinic, Department of Ophthalmology, General Hospital of Lamia
Methods:
retrospective comparative study. 9 patients with glaucoma (10 eyes) and previous phacoemulsification-temporal clear corneal incision- with posterior chamber intraocular lens implantation underwent penetrating glaucoma surgery (trabeculectomy with antimetabolite) due to no further controlled glaucoma (cases). This group was compared to 12 patients (16 eyes) with uncontrolled glaucoma, without any previous ocular surgery, who underwent trabeculectomy with antimetabolite (controls). Follow up time 6 months to 3 years
Results:
In cases group: two patients needed topical antiglaucoma treatment after the first 12 months. One patient (one eye) presented postoperative leak and needed suturing. Transient postoperative hypotonia presented in two patients. No patient experienced visual acuity deterioration or any other major complications. The mean intraocular pressure (IOP) 12 months after trabeculectomy is 12mmHg (range 8-18mmHg). In control group: 8 eyes needed further cataract surgery one month to three years after trabeculectomy, 6 eyes needed supplementary antiglaucoma medication. Additional surgery was deemed necessary in one eye because of trabeculectomy failure after phacoemulsification. Transient postoperative hypotonia in 8 patients resolved during the first postoperative weeks. The mean IOP in trabeculectomy-first (control) group at 12 months post_trabeculectomy is 13.6mmHg (range 6-18mmHg)
Conclusions:
trabeculectomy surgery in patients who have undergone phacoemulsification with temporal clear corneal incision can control IOP while any early postoperative hypotonia is well tolerated. The efficacy of trabeculectomy_ after_ phaco is comparable to that of trabeculectomy_first with the advantage of no vision deterioration due to cataract formation. FINANCIAL DISCLOSURE?: No
