Long-Term Outcome of Cataract Surgery in Eyes with Pseudoexfoliation Syndrome Associated with Weak Zonules: A Case...

A cataract surgery in both eyes was scheduled for an 81-year-old female patient. However, ophthalmic examination revealed marked iridodonesis, phacodonesis and pseudoexfoliative material on the surface of the lens in both eyes indicating weak zonules caused by pseudoexfoliation syndrome, which was more pronounced in the left eye. Cataract surgery was performed initially in the left eye by phacoemulsification. Additionally, iris hooks and capsular tension ring (CTR) were used to stabilize the capsular bag, and the haptic of the intraocular lens (IOL) was sutured to the iris at the end of the surgery. The same procedure except haptic suturing was performed in the right eye after 6 months. The left eye remained stable, whereas the right eye developed considerable anterior capsular contraction 2 months postoperatively. Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy was performed to treat the condition. Moreover, 3 years after the initial surgery, late IOL-CTR-capsular-bag complex dislocation developed in the right eye, and reposition surgery was performed. Three days after IOL-CTR-capsular-bag complex reposition surgery, endophthalmitis developed; the eye responded well to 1 mg intravitreal vancomycin treatment. IOL in the right eye remained stable 3 years postoperatively.
