Methods: A total of 40 eyes of 20 New Zealand white rabbits were randomly divided into six similar groups of 6 to 7 eyes each. After crystalline lens evacuation, one control group (group A) was implanted with a hydrophilic acrylic intraocular lens and no device, and another control group (group B) was implanted with a hydrophobic acrylic intraocular lens and no device.
