Clouding of the Intra-Ocular Lens after cataract surgery：A case report

Backgrand : This case report describes a rare complication of intraocular lens (IOL) opacification in a 76-year-old female patient after age-related cataract surgery in the right eye. Although uncommon, IOL clouding can significantly impair postoperative visual acuity, necessitating surgical intervention. Case presentation : The patient presented with progressive blurred vision in the right eye for one year. We confirmed the diagnosis and identified the underlying cause after thoroughly excluding other potential influencing factors. Subsequently, surgical intervention was performed on the right eye, involving removal of IOL and the re-implantation of new IOL. It resulted in significant improvement in the patient's postoperative vision. Discussion : Clouding of the IOL following cataract surgery is characterized by a reduction in lens transparency after implantation. Although relatively uncommon, this complication can significantly impair vision. The etiology of IOL opacification post-surgery primarily encompasses material-related factors, surgical factors, patient-specific factors, and other miscellaneous factors. In the case under discussion, a hydrophilic acrylic IOL was implanted 12 years prior. After ruling out other potential risk factors, the primary cause was identified as material-related. Consequently, selecting an appropriate IOL for subsequent surgical procedures can help mitigate postoperative complications that may affect visual outcomes. Conclusion : With the advancement of surgical techniques and the introduction of new materials, the incidence of IOL opacification following cataract surgery has significantly decreased. Looking ahead, we will prioritize the use of hydrophobic acrylic IOLs or novel anti-calcification IOLs in future surgeries. This strategic choice aims to further minimize the impact of long-term complications on visual acuity post-cataract surgery.
