ABSTRACT
Intraocular silicone oil can cause complications such as keratopathy, late corneal decompensation, glaucoma, hypotony, and cataract. The optical and sound attenuation properties of silicone oil make axial length measurement and intraocular lens calculation difficult. Different techniques have been recommended to calculate the true axial length and intraocular lens power in silicone oil-filled eyes, each of which has its own limitations. K. Takei et al used X-ray computed tomography to measure the axial length of eyes with incomplete filling of silicone oil in the vitreous cavity. Partial coherence interferometry is a promising alternative method for measuring axial length in eyes with staphyloma or silicone oil. Silicone oil has been used as an appropriate replacement for vitreous in complex vitreoretinal surgery. D. C. Murray et al suggested obtaining the axial length from the axial length measured in the presence of silicone oil multiplied by a factor of 0.71.
