Abstract Details


To report the first case of IOL glistenings 6 months after microincision phacoemulsification and in-the-bag implantation of an enVista MX 60 IOL in a patient with uncontrolled diabetes.


Department of Ophthalmology, Korea University College of Medicine, Seoul, Korea.


A 76-year-old woman with corticonuclear cataract (grade III in the Lens Opacities Classification System III) had uneventful cataract surgery by 2.2mm microincision phacoemulsification and in-the-bag implantation of an enVista MX60 IOL in the right eye. After three months, uneventful cataract surgery and implantation of an Akreos Adapt AO IOL (Bausch & Lomb) had been performed in the left eye. Her fasting blood sugar was 73mg/dl, postprandial 2-hour glucose (PP2) was 274mg/dl and hemoglobin A1C level was 7.5%.


At the 1-week postoperative visit, slit lamp examination revealed no significant ocular inflammation and perfect IOL positioning in the posterior chamber. The BCVA had improved to 0.8 (20/25 Snellen) at 1 month postoperatively. At 6 months, a glistening formation within the IOL optic was observed under slit lamp examination in the right eye. The BCVA was the same as the previous follow-up, which was 0.8 (20/25 Snellen) in the right eye. Her fasting blood sugar was 154mg/dl, postprandial 2-hour glucose (PP2) was 256mg/dl and hemoglobin A1C level was 7.8%.


Our report indicates that glistening formation can develop in patients with uncontrolled diabetes mellitus, even after uneventful phacoemulsification and implantation of the enVista MX60, though it had little effect on the visual acuity. We suggest that elevation of hemoglobin A1C level can be the risk factor for IOL glistening. Tight glycemic control is essential for diabetic patients who require a cataract surgery, even implantation with IOL inducing the least glistening formation.
