 AbstractWhen silicone oil fills the entire vitreous cavity of the aphakic eye, the refractive correction can be expected to change by 5-10 diopters and sometimes as much as 12 diopters. Aphakic eyes become less hyperopic when filled with silicone oil. The vitreo retinal surgeon must anticipate significant changes in refractive error when silicone oil is introduced into the eye. Careful retinoscopy and refractiion are essential for obtaining optimal visual acuity in these patients.
