Transscleral suture fixation of posterior chamber lenses combined with trabeculectomy.
OBJECTIVE
To evaluate the outcome of transscleral suture-fixated posterior chamber intraocular lens (PCIOL) implantation in glaucoma patients when combined with a trabeculectomy.


METHODS
A retrospective study of 56 consecutive glaucoma patients with a minimum follow-up of 6 months after transscleral suture-fixated PCIOL implantation combined with trabeculectomy.


METHODS
Patients were drawn from the clinical glaucoma practice of the Kresge Eye Institute, Detroit, MICHIGAN:


METHODS
Fifty-six eyes of 56 consecutive chronic glaucoma patients who had undergone transscleral suture-fixated PCIOL implantation in combination with a trabeculectomy were included in the analysis.


RESULTS
The mean follow-up time was 38.5 +/- 19.1 months. Mean intraocular pressure (IOP) was significantly reduced, from 22.9 +/- 10.9 mmHg before surgery to 16.7 +/- 6.7 mmHg at the last follow-up visit (P = 0.0005), with the mean number of medications used also significantly decreased, from 2.3 +/- 0.9 to 1.9 +/- 0.9 (P = 0.0002). Postoperative IOP control to 21 mmHg or less was achieved or maintained in 84% of patients. Visual acuity improved or remained stable within two Snellen lines of the preoperative level in 39 eyes (70%) and within three Snellen lines in 45 eyes (80%) at the last follow-up visit. Overall, 46% to 68% of the patients had both stable visual acuity and satisfactory pressure control at the last postoperative visit, depending on criteria of varying stringency. However, 19 eyes (34%) required one or more additional surgical interventions for pressure control. Patients with anterior chamber intraocular lens (ACIOL) complications, diabetes mellitus, or a preoperative IOP level of more than 21 mmHg on maximum tolerated medications were especially prone to requiring additional surgical interventions.


CONCLUSIONS
We conclude that transscleral suture-fixated PCIOL implantation can be combined successfully with a trabeculectomy and can be useful in glaucoma patients in need of both visual rehabilitation and IOP control. However, patients with ACIOL complications, diabetes, or preoperative IOP of more than 21 mmHg on maximum tolerated medications were prone to requiring additional surgical interventions.
