SUMMARY
We studied the refractive ehanges due to the use of intraocular silicone oil in phakic (11) and aphakic (13) eyes.
Phakic eyes became more hiperopic (6,4 D in average) and aphakic eyes became less hiperopic (7,4 in average). These refractive changes occur because the silicone oil has a refractive index higher than those of the ocular media.
