Management Of Intraocular Lens Calification: A Case Report

This case report aims to inform about the management of Intraocular lens (IOL) calcification

This case reported conducted at one of the ophthalmology center in Indonesia

Intraocular lens (IOL) calcification is the appearance of calcium deposits in IOL surface, which usually consists of hydroxyapatite, or another potassium, for example dicalcium phosphate, octalcium phosphate, or tricalcium phosphate. Calcification is the most common hydrophilic acrylic IOL, and the formation of calcium deposits usually appears 6 months after IOL implantation. In this study, we described IOL calcification in a pseudophkic patient evaluated in Malang Eye Center Clinic.

64-year-old women came to the outpatient-eye clinic of Malang Eye Center with chief complaint of blurred vision in her right eye, and sometimes accompanied by glare. Diagnosis was made based on history taking, and complete ophthalmology examination.

Patient had been operated with phacoemulsification + IOL implantiation 12 years ago. Her visual aquity was 6/125 on the right eye, and 6/24 on the left eye, with IOL calcification on her right eye. The patient underwent intraocular lens exchange (explanted a calcified IOL and implanted with new IOL). After 5 months, the visual acuity improved, with OD S+0,25 C-1,50 x 80^o  6/7,5 and OS S-0,50 C-2,75 x 85^o  6/6.

The diagnosis of IOL calsification was often markedly delayed. Especially distinguished from other types of opacities such as glistening and snowflakes degeneration. Proper diagnosis and treatment improve the outcome of IOL calcification.
