Pigmentary Glaucoma After Cataract Surgery with Single-Piece Hydrophobic Intraocular Lens Implanted into the Ciliary Sulcus: Case Report

A 59 years old man presented with a history of phacoemulsification with an hydrophobic intraocular lens implant in his left eye 4 years ago. The biomicroscopy revealed pigments in the corneal endothelium (Krukenberg’s spindle), peripheral transillumination of the iris and intraocular pressure of 52 mmHg in the left eye. Gonioscopy revealed hyperpigmentation of the posterior trabeculate. Posterior segment examination and visual field revealed a cup/disc 0.9 with significant field damage in strategy 10-2. Biomicroscopic ultrasonography showed asymmetric implantation of the IOL loops in the left eye (one loop in the ciliary sulcus and the other in the capsular bag). He underwent antiglaucomatous treatment with adequate control of intraocular pressure, with no need for surgical intervention.

Posterior capsule opacification in pediatric eyes with and without traumatic cataract

To compare the rate of visually significant posterior capsule opacification (PCO) in pediatric eyes with and without traumatic cataract. Storm Eye Institute, Charleston, South Carolina, USA. Retrospective case control study. Eyes operated on for traumatic cataract and having in-the-bag single-piece hydrophobic intraocular lens (IOL) implantation were identified. The control group of eyes operated on for nontraumatic cataract was matched with reference to age, management of the posterior capsule, type of IOL, and follow-up duration. Data from 58 eyes were studied. Age at surgery was comparable between the study group and the control group (7.3 versus 7.8 years) (P = .7). The rate of PCO was statistically significantly different between the 2 groups (12/29 eyes versus 2/29 eyes) (P = .002). This difference was more marked for those with intact posterior capsules (9/12 eyes [75%] and 1/12 eyes [8%] (P = .001) compared with eyes with primary posterior capsulectomy and vitrectomy (3/17 [18%] and 1/17 [6%] (P = .6). For eyes with intact posterior capsules, the duration between cataract surgery and intervention for PCO was 4 to 15 months in the traumatic cataract group; 1 eye in the nontraumatic cataract group required intervention 20 months after surgery. Eyes with traumatic cataract were more likely to develop PCO than eyes without traumatic cataract. The results also suggest that PCO develops faster in eyes with traumatic cataract. Primary posterior capsulectomy and vitrectomy should be considered for children having traumatic cataract surgery, irrespective of age at the time of surgery.
