Adverse Incident Reporting for Ophthalmology
Intraocular lens defect
Intraocular lens may have defect during the manufacturing process and implantation into the patients' eyes. This ranges from the production of IOL, packaging, distribution, insertion to when the IOL is already implanted into the patients' eyes.
This defect may range from manufacturing defect such as no IOL in the box or fracture of haptics or optics. It may also be in the form of deposits on the IOL or opacification detected weeks to years after surgery. All these defects will contribute directly to the patients' visual outcome. Some defects may require explantation and results in distress to both the patients and the surgeons. The cost for explantation of an opacified IOL also has to be borne by the patient and eye care providers.
It is also important to identify any common defect for example fracture of haptics or optics as this will be used as feedback to the industries to improve their IOL quality or be used for platform for further training pertaining to the IOL if required.
Data collected include patient's demography, action taken, outcome and details of IOL.
- To identify any common defect in IOL
- To detect cases with IOL opacification
- To study the patients' characteristics in developing IOL opacification
- To study the patient's outcome following treatment if any
All patients who have undergone cataract surgery and encountered defect in the intraocular IOL delivery system. These cases if detected by any eye care providers should be notified to MOH through this online notification.
