Visual field area in phakic, aphakic, and pseudophakic individuals.
Goldmann perimetry was done on 11 pseudophakic subjects and results were compared to those of age-matched phakic subjects and a third group of aphakic individuals who were wearing rigid gas permeable contact lenses. Testing showed that the I-3 and I-4 fields of the subjects who had had cataract surgery were generally constricted when compared to the normal phakic population. Possible explanations for this include media clarity not being as important a factor in determining field size as was previously thought, peripheral retinal changes, and implant material affecting contrast sensitivity.
