“Yellowing Of An Intraocular Lens Following Chronic Periocular Turmeric Exposure: A Rare Case Report”

To report a rare and unusual case of yellow discoloration of an intraocular lens (IOL) associated with long-term topical exposure to turmeric (Curcuma longa), highlighting a potential non-pharmacological cause of postoperative IOL colour change.

Detailed clinical evaluation, slit-lamp photography, and patient history were analysed in a 60+ year-old woman with pseudophakia who presented with yellowish discoloration of ocular tissues and the implanted IOL.

The patient had a 25-year history of daily periocular and facial application of turmeric as part of a traditional practice. Slit-lamp examination revealed diffuse yellow staining of periocular skin, conjunctiva, cornea, and a distinct yellow discoloration of the IOL optic. No signs of uveitis, IOL opacification, calcification, or posterior capsular opacification were noted. Visual acuity remained relatively preserved.

Chronic external exposure to turmeric may result in pigment deposition and discoloration of intraocular structures, including IOLs. This appears to be a benign but visually striking phenomenon with important counselling and documentation implications for cataract surgeons.
