Abstract Details

Purpose:

The aim of this study was to compare superior and temporal clear corneal incisions of uneventful phacoemulsification and in-the-bag intraocular lens implantation on intraocular pressure control and the bleb morphology in eyes that have undergone previous successful trabeculectomy.

Setting:

Sohag University Hospital

Methods:

In this Prospective case-control study, a total of 100 eyes of 100 patients underwent previous successful trabeculectomy without antimetabolites, divided into two groups. Group A (temporal group) including 50 patients underwent phacoemulsification with a temporal corneal incision and group B (superior group) including 50 patients underwent phacoemulsification with a superior corneal incision. Comparisons between the two groups were performed after one year of follow-up regarding Intraocular pressure changes, bleb morphology score using the Wuerzburg bleb classification score and any added glaucoma medications.

Results:

At the last visit, the mean intraocular pressure for the temporal group was 17.55±1.47 (p=0.51) and for the superior group was 16.90±1.71 (p= 0.85); the difference between the two groups was insignificant (p=0.21). Regarding the bleb morphology, the mean bleb morphology score in the temporal group was 10.50±0.95 (p=0.19) and for the superior group was 10.20±1.06 (p= 0.01).There was an insignificant difference in the bleb grading morphology regarding both groups (p=0.35).

Conclusions:

Our study demonstrates that phacoemulsification whether done with a clear temporal or clear superior wound, does not affect intraocular pressure, bleb morphology or function after one year of follow-up in eyes following previous successful trabeculectomy. Furthermore, cataract surgery may be performed safely in eyes with functioning filtering blebs.
